  • Appending html data when item in html select list is selected

    - by Workoholic
    I have a selector that could look like this: <label for="testselector">Test</label><br /> <select id="testselector" name="test[]" size="5" multiple="multiple"> <option name="test_1" value="1">Test Entry X</option> <option name="test_3" value="2">Test Entry Y</option> <option name="test_5" value="5">Test Entry Z</option> </select> <div id="fieldcontainer"></div> When an entry from the above fields is selected, I want two form fields to appear. I use jquery to add them: $("#fieldcontainer").append("<div><label for=\"testurl\">Test Url</label><br /><input name=\"testurl[]\" type=\"text\" id=\"testurl_1\" value=\"\" /></div>"); $("#fieldcontainer").append("<div><label for=\"testpath\">Test Path</label><br /><input name=\"testpath[]\" type=\"text\" id=\"testpath_1\" value=\"\" /></div>"); I can easily add a click handler to make those form fields appear. But how would I keep track of what form fields were already added? When multiple fields are selected, the appropriate number of input fields needs to be added to the fieldcontainer div. And if they are unselected, the input fields need to be removed again. I also need to retrieve the value from the options in the select list to add them as identifier in the added input fields...

  • New <%: %> Syntax for HTML Encoding Output in ASP.NET 4 (and ASP.NET MVC 2)

    - by ScottGu
    [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] This is the nineteenth in a series of blog posts I’m doing on the upcoming VS 2010 and .NET 4 release. Today’s post covers a small, but very useful, new syntax feature being introduced with ASP.NET 4 – which is the ability to automatically HTML encode output within code nuggets.  This helps protect your applications and sites against cross-site script injection (XSS) and HTML injection attacks, and enables you to do so using a nice concise syntax. HTML Encoding Cross-site script injection (XSS) and HTML encoding attacks are two of the most common security issues that plague web-sites and applications.  They occur when hackers find a way to inject client-side script or HTML markup into web-pages that are then viewed by other visitors to a site.  This can be used to both vandalize a site, as well as enable hackers to run client-script code that steals cookie data and/or exploits a user’s identity on a site to do bad things. One way to help mitigate against cross-site scripting attacks is to make sure that rendered output is HTML encoded within a page.  This helps ensures that any content that might have been input/modified by an end-user cannot be output back onto a page containing tags like <script> or <img> elements.  ASP.NET applications (especially those using ASP.NET MVC) often rely on using <%= %> code-nugget expressions to render output.  Developers today often use the Server.HtmlEncode() or HttpUtility.Encode() helper methods within these expressions to HTML encode the output before it is rendered.  This can be done using code like below: While this works fine, there are two downsides of it: It is a little verbose Developers often forget to call the HtmlEncode method New <%: %> Code Nugget Syntax With ASP.NET 4 we are introducing a new code expression syntax (<%:  %>) that renders output like <%= %> blocks do – but which also automatically HTML encodes it before doing so.  This eliminates the need to explicitly HTML encode content like we did in the example above.  Instead you can just write the more concise code below to accomplish the same thing: We chose the <%: %> syntax so that it would be easy to quickly replace existing instances of <%= %> code blocks.  It also enables you to easily search your code-base for <%= %> elements to find and verify any cases where you are not using HTML encoding within your application to ensure that you have the correct behavior. Avoiding Double Encoding While HTML encoding content is often a good best practice, there are times when the content you are outputting is meant to be HTML or is already encoded – in which case you don’t want to HTML encode it again.  ASP.NET 4 introduces a new IHtmlString interface (along with a concrete implementation: HtmlString) that you can implement on types to indicate that its value is already properly encoded (or otherwise examined) for displaying as HTML, and that therefore the value should not be HTML-encoded again.  The <%: %> code-nugget syntax checks for the presence of the IHtmlString interface and will not HTML encode the output of the code expression if its value implements this interface.  This allows developers to avoid having to decide on a per-case basis whether to use <%= %> or <%: %> code-nuggets.  Instead you can always use <%: %> code nuggets, and then have any properties or data-types that are already HTML encoded implement the IHtmlString interface. Using ASP.NET MVC HTML Helper Methods with <%: %> For a practical example of where this HTML encoding escape mechanism is useful, consider scenarios where you use HTML helper methods with ASP.NET MVC.  These helper methods typically return HTML.  For example: the Html.TextBox() helper method returns markup like <input type=”text”/>.  With ASP.NET MVC 2 these helper methods now by default return HtmlString types – which indicates that the returned string content is safe for rendering and should not be encoded by <%: %> nuggets.  This allows you to use these methods within both <%= %> code nugget blocks: As well as within <%: %> code nugget blocks: In both cases above the HTML content returned from the helper method will be rendered to the client as HTML – and the <%: %> code nugget will avoid double-encoding it. This enables you to default to always using <%: %> code nuggets instead of <%= %> code blocks within your applications.  If you want to be really hardcore you can even create a build rule that searches your application looking for <%= %> usages and flags any cases it finds as an error to enforce that HTML encoding always takes place. Scaffolding ASP.NET MVC 2 Views When you use VS 2010 (or the free Visual Web Developer 2010 Express) you’ll find that the views that are scaffolded using the “Add View” dialog now by default always use <%: %> blocks when outputting any content.  For example, below I’ve scaffolded a simple “Edit” view for an article object.  Note the three usages of <%: %> code nuggets for the label, textbox, and validation message (all output with HTML helper methods): Summary The new <%: %> syntax provides a concise way to automatically HTML encode content and then render it as output.  It allows you to make your code a little less verbose, and to easily check/verify that you are always HTML encoding content throughout your site.  This can help protect your applications against cross-site script injection (XSS) and HTML injection attacks.  Hope this helps, Scott

  • Ban HTML comments from your pages and views

    - by Bertrand Le Roy
    Too many people don’t realize that there are other options than <!-- --> comments to annotate HTML. These comments are harmful because they are sent to the client and thus make your page heavier than it needs to be. When doing ASP.NET, a simple drop-in replacement is server comments, which are delimited by <%-- --%> instead of <!-- -->. Those server comments are visible in your source code, but will never be rendered to the client. Here’s a simple way to sanitize a web site. From Visual Studio, hit CTRL+H to bring the search and replace dialog. Choose “Replace in Files” from the second meny on top of the dialog. Open the find options, check “use” and make sure “Regular expressions” are selected. Use “*.aspx;*.ascx;” as the file types to examine. Choose “Entire Solution” under “Look in”. Here’s the expression to search for comments: \<!--{[^-]*}--\> And here’s the replacement string: <%--\1--%> I usually use the “Find Next” and “Replace” buttons rather than the more brutal “Replace All” in order to not apply the fix blindingly. Once this is done, I do a second manual pass of finds with the same expression to make sure I didn’t miss anything.

  • html multiple frames navigation

    - by Amarsh
    Folks, I want to create a webpage with three panes (frameLeft, frameMiddle, frameRight) The content on leftmost pane is a list from file list.html Upon clicking on an item in the leftmost pane, it loads the corresponding html file (call it listLvl2.html) in the middle pane. This is also a list. Clicking further on an item in the middle pane should load the corresponding html file in the third frame (lets call it content.html) I have made an index.html file with three frames. frameLeft loads list.html. I have coded list.html so that every link opens in the target="frameMiddle" . This works well The issue is opening content.html in frameRight. What should I put as the target in my listLvl2.html links so that they open in frameRight? I tried putting it as frameRight, but instead, it opens in a new window. I guess that is because for listLvl2.html , frameRight is not defined.

  • Integrating HTML into Silverlight Applications

    - by dwahlin
    Looking for a way to display HTML content within a Silverlight application? If you haven’t tried doing that before it can be challenging at first until you know a few tricks of the trade.  Being able to display HTML is especially handy when you’re required to display RSS feeds (with embedded HTML), SQL Server Reporting Services reports, PDF files (not actually HTML – but the techniques discussed will work), or other HTML content.  In this post I'll discuss three options for displaying HTML content in Silverlight applications and describe how my company is using these techniques in client applications. Displaying HTML Overlays If you need to display HTML over a Silverlight application (such as an RSS feed containing HTML data in it) you’ll need to set the Silverlight control’s windowless parameter to true. This can be done using the object tag as shown next: <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%"> <param name="source" value="ClientBin/HTMLAndSilverlight.xap"/> <param name="onError" value="onSilverlightError" /> <param name="background" value="white" /> <param name="minRuntimeVersion" value="4.0.50401.0" /> <param name="autoUpgrade" value="true" /> <param name="windowless" value="true" /> <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50401.0" style="text-decoration:none"> <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="Get Microsoft Silverlight" style="border-style:none"/> </a> </object> By setting the control to “windowless” you can overlay HTML objects by using absolute positioning and other CSS techniques. Keep in mind that on Windows machines the windowless setting can result in a performance hit when complex animations or HD video are running since the plug-in content is displayed directly by the browser window. It goes without saying that you should only set windowless to true when you really need the functionality it offers. For example, if I want to display my blog’s RSS content on top of a Silverlight application I could set windowless to true and create a user control that grabbed the content and output it using a DataList control: <style type="text/css"> a {text-decoration:none;font-weight:bold;font-size:14pt;} </style> <div style="margin-top:10px; margin-left:10px;margin-right:5px;"> <asp:DataList ID="RSSDataList" runat="server" DataSourceID="RSSDataSource"> <ItemTemplate> <a href='<%# XPath("link") %>'><%# XPath("title") %></a> <br /> <%# XPath("description") %> <br /> </ItemTemplate> </asp:DataList> <asp:XmlDataSource ID="RSSDataSource" DataFile="http://weblogs.asp.net/dwahlin/rss.aspx" XPath="rss/channel/item" CacheDuration="60" runat="server" /> </div> The user control can then be placed in the page hosting the Silverlight control as shown below. This example adds a Close button, additional content to display in the overlay window and the HTML generated from the user control. <div id="RSSDiv"> <div style="background-color:#484848;border:1px solid black;height:35px;width:100%;"> <img alt="Close Button" align="right" src="Images/Close.png" onclick="HideOverlay();" style="cursor:pointer;" /> </div> <div style="overflow:auto;width:800px;height:565px;"> <div style="float:left;width:100px;height:103px;margin-left:10px;margin-top:5px;"> <img src="http://weblogs.asp.net/blogs/dwahlin/dan2008.jpg" style="border:1px solid Gray" /> </div> <div style="float:left;width:300px;height:103px;margin-top:5px;"> <a href="http://weblogs.asp.net/dwahlin" style="margin-left:10px;font-size:20pt;">Dan Wahlin's Blog</a> </div> <br /><br /><br /> <div style="clear:both;margin-top:20px;"> <uc:BlogRoller ID="BlogRoller" runat="server" /> </div> </div> </div> Of course, we wouldn’t want the RSS HTML content to be shown until requested. Once it’s requested the absolute position of where it should show above the Silverlight control can be set using standard CSS styles. The following ID selector named #RSSDiv handles hiding the overlay div shown above and determines where it will be display on the screen. #RSSDiv { background-color:White; position:absolute; top:100px; left:300px; width:800px; height:600px; border:1px solid black; display:none; } Now that the HTML content to display above the Silverlight control is set, how can we show it as a user clicks a HyperlinkButton or other control in the application? Fortunately, Silverlight provides an excellent HTML bridge that allows direct access to content hosted within a page. The following code shows two JavaScript functions that can be called from Siverlight to handle showing or hiding HTML overlay content. The two functions rely on jQuery (http://www.jQuery.com) to make it easy to select HTML objects and manipulate their properties: function ShowOverlay() { rssDiv.css('display', 'block'); } function HideOverlay() { rssDiv.css('display', 'none'); } Calling the ShowOverlay function is as simple as adding the following code into the Silverlight application within a button’s Click event handler: private void OverlayHyperlinkButton_Click(object sender, RoutedEventArgs e) { HtmlPage.Window.Invoke("ShowOverlay"); } The result of setting the Silverlight control’s windowless parameter to true and showing the HTML overlay content is shown in the following screenshot:   Thinking Outside the Box to Show HTML Content Setting the windowless parameter to true may not be a viable option for some Silverlight applications or you may simply want to go about showing HTML content a different way. The next technique I’ll show takes advantage of simple HTML, CSS and JavaScript code to handle showing HTML content while a Silverlight application is running in the browser. Keep in mind that with Silverlight’s HTML bridge feature you can always pop-up HTML content in a new browser window using code similar to the following: System.Windows.Browser.HtmlPage.Window.Navigate( new Uri("http://silverlight.net"), "_blank"); For this example I’ll demonstrate how to hide the Silverlight application while maximizing a container div containing the HTML content to show. This allows HTML content to take up the full screen area of the browser without having to set windowless to true and when done right can make the user feel like they never left the Silverlight application. The following HTML shows several div elements that are used to display HTML within the same browser window as the Silverlight application: <div id="JobPlanDiv"> <div style="vertical-align:middle"> <img alt="Close Button" align="right" src="Images/Close.png" onclick="HideJobPlanIFrame();" style="cursor:pointer;" /> </div> <div id="JobPlan_IFrame_Container" style="height:95%;width:100%;margin-top:37px;"></div> </div> The JobPlanDiv element acts as a container for two other divs that handle showing a close button and hosting an iframe that will be added dynamically at runtime. JobPlanDiv isn’t visible when the Silverlight application loads due to the following ID selector added into the page: #JobPlanDiv { position:absolute; background-color:#484848; overflow:hidden; left:0; top:0; height:100%; width:100%; display:none; } When the HTML content needs to be shown or hidden the JavaScript functions shown next can be used: var jobPlanIFrameID = 'JobPlan_IFrame'; var slHost = null; var jobPlanContainer = null; var jobPlanIFrameContainer = null; var rssDiv = null; $(document).ready(function () { slHost = $('#silverlightControlHost'); jobPlanContainer = $('#JobPlanDiv'); jobPlanIFrameContainer = $('#JobPlan_IFrame_Container'); rssDiv = $('#RSSDiv'); }); function ShowJobPlanIFrame(url) { jobPlanContainer.css('display', 'block'); $('<iframe id="' + jobPlanIFrameID + '" src="' + url + '" style="height:100%;width:100%;" />') .appendTo(jobPlanIFrameContainer); slHost.css('width', '0%'); } function HideJobPlanIFrame() { jobPlanContainer.css('display', 'none'); $('#' + jobPlanIFrameID).remove(); slHost.css('width', '100%'); } ShowJobPlanIFrame() handles showing the JobPlanDiv div and adding an iframe into it dynamically. Once JobPlanDiv is shown, the Silverlight control host has its width set to a value of 0% to allow the control to stay alive while making it invisible to the user. I found that this technique works better across multiple browsers as opposed to manipulating the Silverlight control host div’s display or visibility properties. Now that you’ve seen the code to handle showing and hiding the HTML content area, let’s switch focus to the Silverlight application. As a user clicks on a link such as “View Report” the ShowJobPlanIFrame() JavaScript function needs to be called. The following code handles that task: private void ReportHyperlinkButton_Click(object sender, RoutedEventArgs e) { ShowBrowser(_BaseUrl + "/Report.aspx"); } public void ShowBrowser(string url) { HtmlPage.Window.Invoke("ShowJobPlanIFrame", url); } Any URL can be passed into the ShowBrowser() method which handles invoking the JavaScript function. This includes standard web pages or even PDF files. We’ve used this technique frequently with our SmartPrint control (http://www.smartwebcontrols.com) which converts Silverlight screens into PDF documents and displays them. Here’s an example of the content generated:   Silverlight 4’s WebBrowser Control Both techniques shown to this point work well when Silverlight is running in-browser but not so well when it’s running out-of-browser since there’s no host page that you can access using the HTML bridge. Fortunately, Silverlight 4 provides a WebBrowser control that can be used to perform the same functionality quite easily. We’re currently using it in client applications to display PDF documents, SSRS reports and standard HTML content. Using the WebBrowser control simplifies the application quite a bit since no JavaScript is required if the application only runs out-of-browser. Here’s a simple example of defining the WebBrowser control in XAML. I typically define it in MainPage.xaml when a Silverlight Navigation template is used to create the project so that I can re-use the functionality across multiple screens. <Grid x:Name="WebBrowserGrid" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Visibility="Collapsed"> <StackPanel HorizontalAlignment="Stretch" VerticalAlignment="Stretch"> <Border Background="#484848" HorizontalAlignment="Stretch" Height="40"> <Image x:Name="WebBrowserImage" Width="100" Height="33" Cursor="Hand" HorizontalAlignment="Right" Source="/HTMLAndSilverlight;component/Assets/Images/Close.png" MouseLeftButtonDown="WebBrowserImage_MouseLeftButtonDown" /> </Border> <WebBrowser x:Name="JobPlanReportWebBrowser" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" /> </StackPanel> </Grid> Looking through the XAML you can see that a close image is defined along with the WebBrowser control. Because the URL that the WebBrowser should navigate to isn’t known at design time no value is assigned to the control’s Source property. If the XAML shown above is left “as is” you’ll find that any HTML content assigned to the WebBrowser doesn’t display properly. This is due to no height or width being set on the control. To handle this issue the following code is added into the XAML’s code-behind file to dynamically determine the height and width of the page and assign it to the WebBrowser. This is done by handling the SizeChanged event. void MainPage_SizeChanged(object sender, SizeChangedEventArgs e) { WebBrowserGrid.Height = JobPlanReportWebBrowser.Height = ActualHeight; WebBrowserGrid.Width = JobPlanReportWebBrowser.Width = ActualWidth; } When the user wants to view HTML content they click a button which executes the code shown in next: public void ShowBrowser(string url) { if (Application.Current.IsRunningOutOfBrowser) { JobPlanReportWebBrowser.NavigateToString("<html><body><iframe src='" + url + "' style='width:100%;height:97%;' /></body></html>"); WebBrowserGrid.Visibility = Visibility.Visible; } else { HtmlPage.Window.Invoke("ShowJobPlanIFrame", url); } } private void WebBrowserImage_MouseLeftButtonDown(object sender, MouseButtonEventArgs e) { WebBrowserGrid.Visibility = Visibility.Collapsed; }   Looking through the code you’ll see that it checks to see if the Silverlight application is running out-of-browser and then either displays the WebBrowser control or runs the JavaScript function discussed earlier. Although the WebBrowser control’s Source property could be assigned the URI of the page to navigate to, by assigning HTML content using the NavigateToString() method and adding an iframe, content can be shown from any site including cross-domain sites. This is especially handy when you need to grab a page from a reporting site that’s in a different domain than the Silverlight application. Here’s an example of viewing  PDF file inside of an out-of-browser application. The first image shows the application running out-of-browser before the user clicks a PDF HyperlinkButton.  The second image shows the PDF being displayed.   While there are certainly other techniques that can be used, the ones shown here have worked well for us in different applications and provide the ability to display HTML content in-browser or out-of-browser. Feel free to add a comment if you have another tip or trick you like to use when working with HTML content in Silverlight applications.   Download Code Sample   For more information about onsite, online and video training, mentoring and consulting solutions for .NET, SharePoint or Silverlight please visit http://www.thewahlingroup.com.

  • Restricting Input in HTML Textboxes to Numeric Values

    - by Rick Strahl
    Ok, here’s a fairly basic one – how to force a textbox to accept only numeric input. Somebody asked me this today on a support call so I did a few quick lookups online and found the solutions listed rather unsatisfying. The main problem with most of the examples I could dig up was that they only include numeric values, but that provides a rather lame user experience. You need to still allow basic operational keys for a textbox – navigation keys, backspace and delete, tab/shift tab and the Enter key - to work or else the textbox will feel very different than a standard text box. Yes there are plug-ins that allow masked input easily enough but most are fixed width which is difficult to do with plain number input. So I took a few minutes to write a small reusable plug-in that handles this scenario. Imagine you have a couple of textboxes on a form like this: <div class="containercontent"> <div class="label">Enter a number:</div> <input type="text" name="txtNumber1" id="txtNumber1" value="" class="numberinput" /> <div class="label">Enter a number:</div> <input type="text" name="txtNumber2" id="txtNumber2" value="" class="numberinput" /> </div> and you want to restrict input to numbers. Here’s a small .forceNumeric() jQuery plug-in that does what I like to see in this case: [Updated thanks to Elijah Manor for a couple of small tweaks for additional keys to check for] <script type="text/javascript"> $(document).ready(function () { $(".numberinput").forceNumeric(); }); // forceNumeric() plug-in implementation jQuery.fn.forceNumeric = function () { return this.each(function () { $(this).keydown(function (e) { var key = e.which || e.keyCode; if (!e.shiftKey && !e.altKey && !e.ctrlKey && // numbers key >= 48 && key <= 57 || // Numeric keypad key >= 96 && key <= 105 || // comma, period and minus key == 190 || key == 188 || key == 109 || // Backspace and Tab and Enter key == 8 || key == 9 || key == 13 || // Home and End key == 35 || key == 36 || // left and right arrows key == 37 || key == 39 || // Del and Ins key == 46 || key == 45) return true; return false; }); }); } </script> With the plug-in in place in your page or an external .js file you can now simply use a selector to apply it: $(".numberinput").forceNumeric(); The plug-in basically goes through each selected element and hooks up a keydown() event handler. When a key is pressed the handler is fired and the keyCode of the event object is sent. Recall that jQuery normalizes the JavaScript Event object between browsers. The code basically white-lists a few key codes and rejects all others. It returns true to indicate the keypress is to go through or false to eat the keystroke and not process it which effectively removes it. Simple and low tech, and it works without too much change of typical text box behavior.© Rick Strahl, West Wind Technologies, 2005-2011Posted in JavaScript  jQuery  HTML

  • make my file readable as either Perl or HTML

    - by JoelFan
    In the spirit of the "Perl Preamble" where a script works properly whether executed by a shell script interpreter or the Perl interpreter... I have a Perl script which contains an embedded HTML document (as a "heredoc"), i.e.: #!/usr/bin/perl ... some perl code ... my $html = <<'END' ; <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> ... more HTML ... </html> END ... perl code that processes $html ... I would like to be able to work on the HTML that's inside the Perl script and check it out using a web browser, and only run the script when the HTML is the way I want. To accomplish this, I need the file to be openable both as an HTML file and as a Perl script. I have tried various tricks with Perl comments and HTML comments but can't get it quite perfect. It doesn't have to be "strictly legal" HTML... just displayable in a browser with no (or minimal) Perl garbage visible.

  • How to save Word documents as HTML to be viewed in Firefox

    - by private_meta
    I'm in need for saving a Word document as HTML. It has some background images, other images, texts, ... It opens correctly in Internet Explorer, but how can I save a word doc as HTML so that Firefox and other current browsers render it correctly? All images are missing in the document. I looked through the generated html document, but the paths for the images appear to be correct. Any idea? Things like "Don't save docs as html" won't be helpful here. Edit: To make myself clear, the normal "Save as HTML" doesn't cut it, the result is broken in any browser other than Internet Explorer. Edit 2: What I'm using is Word 2010 and Firefox 4. I also tried rendering it in the latest Chrome version, which failed as well. I used different compatibility settings for saving as html, it did not help

  • Translate report data export from RUEI into HTML for import into OpenOffice Calc Spreadsheets

    - by [email protected]
    A common question of users is, How to import the data from the automated data export of Real User Experience Insight (RUEI) into tools for archiving, dashboarding or combination with other sets of data.XML is well-suited for such a translation via the companion Extensible Stylesheet Language Transformations (XSLT). Basically XSLT utilizes XSL, a template on what to read from your input XML data file and where to place it into the target document. The target document can be anything you like, i.e. XHTML, CSV, or even a OpenOffice Spreadsheet, etc. as long as it is a plain text format.XML 2 OpenOffice.org SpreadsheetFor the XSLT to work as an OpenOffice.org Calc Import Filter:How to add an XML Import Filter to OpenOffice CalcStart OpenOffice.org Calc andselect Tools > XML Filter SettingsNew...Fill in the details as follows:Filter name: RUEI Import filterApplication: OpenOffice.org Calc (.ods)Name of file type: Oracle Real User Experience InsightFile extension: xmlSwitch to the transformation tab and enter/select the following leaving the rest untouchedXSLT for import: ruei_report_data_import_filter.xslPlease see at the end of this blog post for a download of the referenced file.Select RUEI Import filter from list and Test XSLTClick on Browse to selectTransform file: export.php.xmlOpenOffice.org Calc will transform and load the XML file you retrieved from RUEI in a human-readable format.You can now select File > Open... and change the filetype to open your RUEI exports directly in OpenOffice.org Calc, just like any other a native Spreadsheet format.Files of type: Oracle Real User Experience Insight (*.xml)File name: export.php.xml XML 2 XHTMLMost XML-powered browsers provides for inherent XSL Transformation capabilities, you only have to reference the XSLT Stylesheet in the head of your XML file.

  • Build tools for php, html, css, js web app development

    What are some recommendations for a build tool that would allow me to upload changes to a web server or a repository and minify the js and css automatically, and possibly even run Closure compiler on the JavaScript? Im not worried about doing anything with the php code other than update with most recent changes although in the future would like to have phpdoc updated automatically. Just wondering if there is some way to do all this other than an amalgam of scripts that run or have to be invoked every time. Thanks.

  • Suggestions for html tag info required for jQuery Plugin

    - by Toby Allen
    I have written a tiny bit of jQuery which simply selects all the Select form elements on the page and sets the selected property to the correct value. Previously I had to write code to generate the Select in php and specify the Selected attribute for the option that was selected or do loads of if statements in my php page or smarty template. Obviosly the information about what option is selected still needs to be specified somewhere in the page so the jQuery code can select it. I decided to create a new attribute on the Select item <Select name="MySelect" SelectedOption="2"> <-- Custom Attr SelectedOption <option value="1">My Option 1 </option> <option value="2">My Option 2 </option> <-- this option will be selected when jquery code runs <option value="3">My Option 3 </option> <option value="4">My Option 4 </option> </Select> Does anyone see a problem with using a custom attribute to do this, is there a more accepted way, or a better jquery way?

    - by yes123
    Hi guys, I am thinking to switch to CSS Sprite for my images. The main problem is I need something compatible with alt attribute. (Seo-purpouse) What Can I use? The first think I thought was to use a standard <img src="1x1.gif" class="mysprite"> The problem is I can't use that because that would like suspicous by google because of this: <img src="1x1.gif" class="mysprite" alt="my keyword1"> <img src="1x1.gif" class="mysprite" alt="my keyword2"> <img src="1x1.gif" class="mysprite" alt="my keyword3"> (the same image "1x1.gif" with different alt text) How we can solve this?

  • From .psd to working HTML and CSS - help me suck less

    - by kevinmajor1
    I am not much of a designer. My strength lies in coding. That said, I'm often forced into the role of "The Man," responsible for all aspects of site creation. So, that said I'm wondering if the pros can give me tips/solutions/links to tutorials to my main questions. Resolution. What should I aim for? What are the lower and upper edges I should be aware of? I know that systems like 960 Grid were popular recently. Is that the number I should still aim for? Slicing up a .psd - are there any tricks I should know? I've always found it difficult to get my slices pixel perfect. I'm also really slow at it. I must be looking at it wrong, or missing something fundamental. The same goes for text. Layouts are always filled with the classic "Lorem...", but I can never seem to get real content to fit quite as well on the screen. The advanced (to me, anyway) looking things, like a part of a logo/image overlaying what looks like a content area. How does one do that? How do layouts change/are informed by the decision to go fixed or liquid? Again, any tips/tricks/suggestions/tutorials you can share would be greatly appreciated.

  • displaying multi-section html documents - best practices

    - by ecpepper
    I work at a research organization and we publish a lot of large-ish documents, usually organized in sections. What I want to know is how best to present these multi-section documents on our website. Presently, what I do is load the entire document as a single page, with each section as its own div. Then I show and hide divs as needed via a table of contents and "next" and "prev" buttons. The advantages to this are mainly: 1) that you can move between sections very quickly, 2) it produces consistent analytics (when a page is loaded, I know a report is being read). The disadvantages, however, are real: Readers can't take advantage of browser back/forward buttons to move between sections. It's complicated to create direct links to individual sections (I can do it with javascript but it's not easy for other people to grab and share). For long reports, you have to wait for the full report to load before you can move around (and that can include hordes of images and charts). Do other people have thoughts on better ways to organize this? Here's an example of the current system: http://massbudget.org/825

  • Practical considerations for HTML / CSS naming conventions (syntax)

    - by Jeroen
    Question: what are the practical considerations for the syntax in class and id values? Note that I'm not asking about the semantics, i.e. the actual words that are being used, as for example described in this blogpost. There are a lot of resources on that side of naming conventions already, in fact obscuring my search for practical information on the various syntactical bits: casing, use of interpunction (specifically the - dash), specific characters to use or avoid, etc. To sum up the reasons I'm asking this question: The naming restrictions on id and class don't naturally lead to any conventions The abundance of resources on the semantic side of naming conventions obscure searches on the syntactic considerations I couldn't find any authorative source on this There wasn't any question on SE Programmers yet on this topic :) Some of the conventions I've considered using: UpperCamelCase, mainly as a cross-over habit from server side coding lowerCamelCase, for consistency with JavaScript naming conventions css-style-classes, which is consistent with naming of css properties (but can be annoying when Ctrl+Shift+ArrowKey selection of text) with_under_scores, which I personally haven't seen used much alllowercase, simple to remember but can be hard to read for longer names UPPERCASEFTW, as a great way to annoy your fellow programmers (perhaps combined with option 4 for readability) And probably I've left out some important options or combinations as well. So: what considerations are there for naming conventions, and to which convention do they lead?

  • HTML coding style: attribute starts on a new line

    - by Matty
    sublvl's front end developer seems to have a strange coding style that I've never seen before. Every time they begin a new element, immediately after the element name they insert a line break. The first thing that appears on the next line is the first attribute of the element. For example: id="player-container"><div id="player-bar"><div id="player-controls-wrapper"><div id="player-controls"><div id ="player-controls-buttons"> <a The above code was found here. I've never seen this kind of coding style before. What's going on here? Is this just a quirky style or is there some reasoning behind it?

  • Does sitewide html refactoring affect Google traffic?

    - by Name
    Good morning, I have recently made a big structural change on my site and the very next day the number of Google impressions went from 75.000 to 3.000, with a proportional drop of traffic from searches. No URLs were changed, neither were the page titles or descriptions. Everything is exactly the same, but different looking, except that it does barely appear on Google anymore. Anybody has a clue to why?

  • Render Ruby object to interactive html

    - by AvImd
    I am developing a tool that discovers network services enabled on host and writes short summary on them like this: init,1 +-- login,1560 -- +-- bash,1629 +-- nc,12137 -lup 50505 { :net = [ [0] "*:50505 IPv4 UDP " ], :fds = [ [0] "/root (cwd)", [1] "/", [2] "/bin/nc.traditional", [3] "/xochikit/ld_poison.so (stat: No such file or directory)", [4] "/dev/tty2", [5] "*:50505" ] } It proved to be very nice formatted and useful for quick discovery thanks to colors provided by the awesome_print gem. However, its output is just a text. One issue is that if I want to share it, I lose colors. I'd also like to fold and unfold parts of objects, quickly jump to specific processes and what not? Adding comments, for example. Thus I want something web-based. What is the best approach to implement features like these? I haven't worked with web interfaces before and I don't have much experience with Ruby.

  • Does jQuery strip some html elements from a string when using .html()?

    - by Nic Hubbard
    I have a var that contains a full html page, including the head, html, body, etc. When I pass that string into the .html() function, jQuery strips out all those elements, such as body, html, head, etc, which I don't want. My data var contains: <html> <head> <title>Untitled Document</title> </head> <body> </body> </html> // data is a full html document string data = $('<div/>').html(data); // jQuery stips my document string! alert(data.find('head').html()); I am needing to manipulate a full html page string, so that I can return what is in the element. I would like to do this with jQuery, but it seems all of the methods, append(), prepend() and html() all try to convert the string to dom elements, which remove all the other parts of a full html page. Is there another way that I could do this? I would be fine using another method. My final goal is to find certain elements inside my string, so I figured jQuery would be best, since I am so used to it. But, if it is going to trim and remove parts of my string, I am going to have to look for another method. Ideas?

  • COMPLETE list of HTML tag attributes which have a URL value?

    - by system PAUSE
    Besides the following, are there any HTML tag attributes that have a URL as their value? href attribute on tags: <link>, <a>, <area> src attribute on tags: <img>, <iframe>, <frame>, <embed>, <script>, <input> action attribute on tags: <form> data attribute on tags: <object> Looking for tags in wide usage, including non-standard tags and old browsers as well as HTML 4.01, HTML 5, and XHTML. Yes this question is kinda lightweight, but I googled around for about 45 minutes and didn't find this data centralized anywhere, so I figure it might help some other developer to have it here. Plus I'm sure I'm missing something. Feel free to repeat/reorganize this list in your answer. Upvoting the most complete answers will probably be most helpful to others.
