    - by John Jones
    Afternoon, Bit of a tricky question this one, I have a website and need to translate the pages into french, I am using google translate API to do the translation.

  • Convert codes to HTML with CSS style

    - by David.Chu.ca
    I normally use VIM to edit my codes and convert them to HTML by using TOhtml command. The only thing I don't like is that the converted HTML does not have css class style definitions. I am not sure if there is tool to convert codes to HTML with css, or I can use additional tool or command to convert HTML HTML with css?

  • python: html writer?

    - by Bin Chen
    With jquery it's very easy to insert some element inside another element using the selector technology, I am wondering if there is any python library that can do things similar with jquery, the reason is I want server side python program to produce the static pages, which needs to parse the html and insert something into it. Or other alternative, not in python language at all? EDIT: To be clear, I want to use python to write below program: h = html.parse('temp.html') h.find('#idnum').html('<b>my html generated</b>') h.close()

  • Visual Studio 2013, ASP.NET MVC 5 Scaffolded Controls, and Bootstrap

    - by plitwin
    A few days ago, I created an ASP.NET MVC 5 project in the brand new Visual Studio 2013. I added some model classes and then proceeded to scaffold a controller class and views using the Entity Framework. Scaffolding Some Views Visual Studio 2013, by default, uses the Bootstrap 3 responsive CSS framework. Great; after all, we all want our web sites to be responsive and work well on mobile devices. Here’s an example of a scaffolded Create view as shown in Google Chrome browser   Looks pretty good. Okay, so let’s increase the width of the Title, Description, Address, and Date/Time textboxes. And decrease the width of the  State and MaxActors textbox controls. Can’t be that hard… Digging Into the Code Let’s take a look at the scaffolded Create.cshtml file. Here’s a snippet of code behind the Create view. Pretty simple stuff. @using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class="form-horizontal"> <h4>RandomAct</h4> <hr /> @Html.ValidationSummary(true) <div class="form-group"> @Html.LabelFor(model => model.Title, new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> </div> <div class="form-group"> @Html.LabelFor(model => model.Description, new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.EditorFor(model => model.Description) @Html.ValidationMessageFor(model => model.Description) </div> </div> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } A little more digging and I discover that there are three CSS files of importance in how the page is rendered: boostrap.css (and its minimized cohort) and site.css as shown below.   The Root of the Problem And here’s the root of the problem which you’ll find the following CSS in Site.css: /* Set width on the form input elements since they're 100% wide by default */ input, select, textarea { max-width: 280px; } .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Yes, Microsoft is for some reason setting the maximum width of all input, select, and textarea controls to 280 pixels. Not sure the motivation behind this, but until you change this or overrride this by assigning the form controls to some other CSS class, your controls will never be able to be wider than 280px. The Fix Okay, so here’s the deal: I hope to become very competent in all things Bootstrap in the near future, but I don’t think you should have to become a Bootstrap guru in order to modify some scaffolded control widths. And you don’t. Here is the solution I came up with: Find the aforementioned CSS code in SIte.css and change it to something more tenable. Such as: /* Set width on the form input elements since they're 100% wide by default */ input, select, textarea { max-width: 600px; } Because the @Html.EditorFor html helper doesn’t support the passing of HTML attributes, you will need to repalce any @Html.EditorFor() helpers with @Html.TextboxFor(), @Html.TextAreaFor, @Html.CheckBoxFor, etc. helpers, and then add a custom width attribute to each control you wish to modify. Thus, the earlier stretch of code might end up looking like this: @using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class="form-horizontal"> <h4>Random Act</h4> <hr /> @Html.ValidationSummary(true) <div class="form-group"> @Html.LabelFor(model => model.Title, new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.TextBoxFor(model => model.Title, new { style = "width: 400px" }) @Html.ValidationMessageFor(model => model.Title) </div> </div> <div class="form-group"> @Html.LabelFor(model => model.Description, new { @class = "control-label col-md-2" }) <div class="col-md-10"> @Html.TextAreaFor(model => model.Description, new { style = "width: 400px" }) @Html.ValidationMessageFor(model => model.Description) </div> </div> .csharpcode, .csharpcode pre { font-size: small; color: black; font-family: consolas, "Courier New", courier, monospace; background-color: #ffffff; /*white-space: pre;*/ } .csharpcode pre { margin: 0em; } .csharpcode .rem { color: #008000; } .csharpcode .kwrd { color: #0000ff; } .csharpcode .str { color: #006080; } .csharpcode .op { color: #0000c0; } .csharpcode .preproc { color: #cc6633; } .csharpcode .asp { background-color: #ffff00; } .csharpcode .html { color: #800000; } .csharpcode .attr { color: #ff0000; } .csharpcode .alt { background-color: #f4f4f4; width: 100%; margin: 0em; } .csharpcode .lnum { color: #606060; } Resulting Form Here’s what the page looks like after the fix: Technorati Tags: ASP.NET MVC,ASP.NET MVC 5,Bootstrap

  • Using rounded corners in modern websites with CSS3

    - by nikolaosk
    This is going to be the sixth post in a series of posts regarding HTML 5. You can find the other posts here , here, here , here and here.In this post I will provide a hands-on example on how to use rounded corners (rounded corners in CSS3) in your website. I think this is the feature that is most required in the new modern websites.Most websites look great with their lovely round panels and rounded corner tab style menus. We could achieve that effect earlier but we should resort to complex CSS rules and images. I will show you how to accomplish this great feature with the power of CSS 3.We will not use Javascript.Javascript is required for IE 7, IE 8 and the notorious IE 6. The best solution for implementing corners using CSS and Javascript without using images is Nifty corners cube. There are detailed information how to achieve this in the link I provided. This solution is tested in earlier vesrions of IE (IE 6,IE 7,IE 8) and Opera,Firefox,Safari. In order to be absolutely clear this is not (and could not be) a detailed tutorial on HTML 5. There are other great resources for that.Navigate to the excellent interactive tutorials of W3School.Another excellent resource is HTML 5 Doctor.Two very nice sites that show you what features and specifications are implemented by various browsers and their versions are http://caniuse.com/ and http://html5test.com/. At this times Chrome seems to support most of HTML 5 specifications.Another excellent way to find out if the browser supports HTML 5 and CSS 3 features is to use the Javascript lightweight library Modernizr.In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like.You can use Visual Studio 2012 Express edition. You can download it here.Before I go on with the actual demo I will use the (http://www.caniuse.com) to see the support for web fonts from the latest versions of modern browsers.Please have a look at the picture below. We see that all the latest versions of modern browsers support this feature.We can see that even IE 9 supports this feature.  Let's move on with the actual demo. This is going to be a rather simple demo.I create a simple HTML 5 page. The markup follows and it is very easy to use and understand <!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">       </head>  <body>      <div id="header">      <h1>Learn cutting edge technologies</h1>    </div>        <div id="main">          <h2>HTML 5</h2>                        <p id="panel1">            HTML5 is the latest version of HTML and XHTML. The HTML standard defines a single language that can be written in HTML and XML. It attempts to solve issues found in previous iterations of HTML and addresses the needs of Web Applications, an area previously not adequately covered by HTML.          </p>      </div>             </body>  </html>Then I need to write the various CSS rules that style this markup. I will name it style.css   body{        line-height: 38px;        width: 1024px;        background-color:#eee;        text-align:center;      }#panel1 { margin:auto; text-align:left; background-color:#77cdef;width:400px; height:250px; padding:15px;font-size:16px;font-family:tahoma;color:#fff;border-radius: 20px;}Have a look below to see what my page looks like in IE 10. This is possible through the border-radious property. The colored panel has all four corners rounded with the same radius.We can add a border to the rounded corner panel by adding this property declaration in the #panel1,  border:4px #000 solid;We can have even better visual effects if we specify a radius for each corner.This is the updated version of the style.css. body{        line-height: 38px;        width: 1024px;        background-color:#eee;        text-align:center;      }#panel1 { margin:auto; text-align:left; background-color:#77cdef;border:4px #000 solid;width:400px; height:250px; padding:15px;font-size:16px;font-family:tahoma;color:#fff;border-top-left-radius: 20px;border-top-right-radius: 70px;border-bottom-right-radius: 20px;border-bottom-left-radius: 70px;} This is how my page looks in Firefox 15.0.1  In this final example I will show you how to style with CSS 3 (rounded corners) a horizontal navigation menu. This is the new version of the HTML markup<!DOCTYPE html><html lang="en">  <head>    <title>HTML 5, CSS3 and JQuery</title>    <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >    <link rel="stylesheet" type="text/css" href="style.css">       </head>  <body>      <div id="header">      <h1>Learn cutting edge technologies</h1>    </div>        <div id="nav"><ul><li><a class="mymenu" id="activelink" href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8934038#">Main</a></li><li><a class="mymenu" href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8934038#">HTML 5</a></li><li><a class="mymenu" href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8934038#">CSS 3</a></li><li><a class="mymenu" href="http://weblogs.asp.net/controlpanel/blogs/posteditor.aspx?SelectedNavItem=Posts§ionid=1153&postid=8934038#">JQuery</a></li></ul></div>        <div id="main">          <h2>HTML 5</h2>                        <p id="panel1">            HTML5 is the latest version of HTML and XHTML.

  • Knockout with ASP.Net MVC2 - HTML Extension Helpers for input controls

    Goal: Defining Knockout-style input controls can be tedious and also may be something that you may find obtrusive, mixing your HTML with data bind syntax as well as binding your aspx, ascx files to Knockout.

The third overloaded method does it client-side via the viewmodel. The first two overloads can be done when you have no requirement to add complex JSON objects to your lists. Furthermore, why render and parse the JSON object when you can have it all built and rendered server-side like any other list control.

  • Highlighting rows and columns in an HTML table using JQuery

    - by nikolaosk
    A friend of mine was seeking some help regarding HTML tables and JQuery. I have decided to write a few posts demonstrating the various techniques I used with JQuery to achieve the desired functionality. ?here are other posts in my blog regarding JQuery.You can find them all here.I have received some comments from visitors of this blog that are "complaining" about the length of the blog posts. I will not write lengthy posts anymore...I mean I will try not to do so..We will demonstrate this with a step by step example. I will use Visual Studio 2012 Ultimate. You can also use Visual Studio 2012 Express Edition. You can also use VS 2010 editions. 1) Launch Visual Studio. Create an ASP.Net Empty Web application. Choose an appropriate name for your application.2) Add a web form, default.aspx page to the application.3) Add a table from the HTML controls tab control (from the Toolbox) on the default.aspx page4) Now we need to download the JQuery library. Please visit the http://jquery.com/ and download the minified version.5) We will add a stylesheet to the application (Style.css)5) Obviously at some point we need to reference the JQuery library and the external stylesheet. In the head section ? add the following lines.   <link href="Style.css" rel="stylesheet" type="text/css" />       <script src="jquery-1_8_2_min.js" type="text/javascript"></script> 6) Now we need to highlight the rows when the user hovers over them.7) First we need to type the HTML markup<body>    <form id="form1" runat="server">    <div>        <h1>Liverpool Legends</h1>        <table style="width: 50%;" border="1" cellpadding="10" cellspacing ="10">            <thead>                <tr><th>Defenders</th><th>MidFielders</th><th>Strikers</th></tr>            </thead>            <tbody>            <tr>                <td>Alan Hansen</td>                <td>Graeme Souness</td>                <td>Ian Rush</td>            </tr>            <tr>                <td>Alan Kennedy</td>                <td>Steven Gerrard</td>                <td>Michael Owen</td>            </tr>            <tr>                <td>Jamie Garragher</td>                <td>Kenny Dalglish</td>                <td>Robbie Fowler</td>            </tr>            <tr>                <td>Rob Jones</td>                <td>Xabi Alonso</td>                <td>Dirk Kuyt</td>            </tr>                </tbody>        </table>            </div>    </form></body>8) Now we need to write the simple rules in the style.css file.body{background-color:#eaeaea;}.hover { background-color:#42709b; color:#ff6a00;} 8) Inside the head section we also write the simple JQuery code.  <script type="text/javascript"> $(document).ready(function() { $('tr').hover( function() { $(this).find('td').addClass('hover'); }, function() { $(this).find('td').removeClass('hover'); } ); }); </script>9) Run your application and see the row changing background color and text color every time the user hovers over it. Let me explain how this functionality is achieved.We have the .hover style rule in the style.css file that contains some properties that define the background color value and the color value when the mouse will be hovered on the row.In the JQuery code we do attach the hover() event to the tr elements.The function that is called when the hovering takes place, we search for the td element and through the addClass function we apply the styles defined in the .hover class rule in the style.css file.I remove the .hover rule styles with the removeClass function. Now let's say that we want to highlight only alternate rows of the table.We need to add another rule in the style.css.alternate { background-color:#42709b; color:#ff6a00;} The JQuery code (comment out the previous JQuery code) follows  <script type="text/javascript">        $(document).ready(function() {                     $('table tr:odd').addClass('alternate');        });    </script>  When I run my application through VS I see the following result You can do that with columns as well. You can highlight alternate columns as well.The JQuery code (comment out the previous JQuery code) follows  <script type="text/javascript">        $(document).ready(function() {                      $('td:nth-child(odd)').addClass('alternate');        });    </script>  In this script I use the nth-child() method in the JQuery code.This method retrieves all the elements that are nth children of their parent.Have a look at the picture below to see the resultsYou can also change color to each individual cell when hovered on.The JQuery code (comment out the previous JQuery code) follows    <script type="text/javascript">        $(document).ready(function() {          $('td').hover(                  function() {                 $(this).addClass('hover');               },                function() {                    $(this).removeClass('hover');                }                );        });    </script> Have a look at the picture below to see the results. Hope it helps!!!

  • urllib2 misbehaving with dynamically loaded content

    - by Sheena
    Some Code headers = {} headers['user-agent'] = 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:16.0) Gecko/20100101 Firefox/16.0' headers['Accept'] = 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8' headers['Accept-Language'] = 'en-gb,en;q=0.5' #headers['Accept-Encoding'] = 'gzip, deflate' request = urllib.request.Request(sURL, headers = headers) try: response = urllib.request.urlopen(request) except error.HTTPError as e: print('The server couldn\'t fulfill the request.') print('Error code: {0}'.format(e.code)) except error.URLError as e: print('We failed to reach a server.') print('Reason: {0}'.format(e.reason)) else: f = open('output/{0}.html'.format(sFileName),'w') f.write(response.read().decode('utf-8')) A url http://groupon.cl/descuentos/santiago-centro The situation Here's what I did: enable javascript in browser open url above and keep an eye on the console disable javascript repeat step 2 use urllib2 to grab the webpage and save it to a file enable javascript open the file with browser and observe console repeat 7 with javascript off results In step 2 I saw that a whole lot of the page content was loaded dynamically using ajax. So the HTML that arrived was a sort of skeleton and ajax was used to fill in the gaps. This is fine and not at all surprising Since the page should be seo friendly it should work fine without js. in step 4 nothing happens in the console and the skeleton page loads pre-populated rendering the ajax unnecessary. This is also completely not confusing in step 7 the ajax calls are made but fail. this is also ok since the urls they are using are not local, the calls are thus broken. The page looks like the skeleton. This is also great and expected. in step 8: no ajax calls are made and the skeleton is just a skeleton. I would have thought that this should behave very much like in step 4 question What I want to do is use urllib2 to grab the html from step 4 but I cant figure out how. What am I missing and how could I pull this off? To paraphrase If I was writing a spider I would want to be able to grab plain ol' HTML (as in that which resulted in step 4). I dont want to execute ajax stuff or any javascript at all. I don't want to populate anything dynamically. I just want HTML. The seo friendly site wants me to get what I want because that's what seo is all about. How would one go about getting plain HTML content given the situation I outlined? To do it manually I would turn off js, navigate to the page and copy the html. I want to automate this. stuff I've tried I used wireshark to look at packet headers and the GETs sent off from my pc in steps 2 and 4 have the same headers. Reading about SEO stuff makes me think that this is pretty normal otherwise techniques such as hijax wouldn't be used. Here are the headers my browser sends: Host: groupon.cl User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:16.0) Gecko/20100101 Firefox/16.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-gb,en;q=0.5 Accept-Encoding: gzip, deflate Connection: keep-alive Here are the headers my script sends: Accept-Encoding: identity Host: groupon.cl Accept-Language: en-gb,en;q=0.5 Connection: close Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 User-Agent: User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:16.0) Gecko/20100101 Firefox/16.0 The differences are: my script has Connection = close instead of keep-alive. I can't see how this would cause a problem my script has Accept-encoding = identity. This might be the cause of the problem. I can't really see why the host would use this field to determine the user-agent though. If I change encoding to match the browser request headers then I have trouble decoding it. I'm working on this now... watch this space, I'll update the question as new info comes up

  • Rendering a UIWebView in drawRect with loadHTMLString

    - by Nick Weaver
    Hello there, I am having a problem with UIWebView. I'd like to render my own html code in it. When I add a webview as a subview and put in some html code it renders just fine. When it gets down to some optimized drawing of tableview cell with the drawRect method the problem pops up. Drawing UIView descendants works pretty well this way. It's even possible to load a URL with the loadRequest method, setting the delegate, conforming to the UIWebViewDelegate protocol and redrawing the table cell with setNeedsDisplay when webViewDidFinishLoad is called. It does show, but when it comes to loadHTMLString, nothing shows up, only a white rect. Due to performance reasons I have to do the drawing in the drawRect method. Any ideas? Thanks in advance Nick Example snippet code for the html code being loaded by a UIWebView: NSString *html = @"<html><head><title>My fancy webview</title></head><body style='background-color:green;'><p>It somehow seems<h2 style='color:black;'>this does not show up in drawRect</h2>!</p></body></html>"; [webView loadHTMLString:html baseURL:nil]; Snippet for the drawRect method: - (void)drawRect:(CGRect)aRect { CGContextRef context = UIGraphicsGetCurrentContext(); [[webView layer] renderInContext:context]; }

  • HTML: How to create a DIV with only vertical scroll-bar to show long paragraphs on a webpage?

    - by Awan
    I want to show terms and condition note on my website. I dont want to use text field and also dont want to use my whole page. I just want to display my text in selected area and want to use only vertical scroll-bar to go down and read all text. Currently I am using this code: <div style="width:10;height:10;overflow:scroll" > text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text </div> It is not fixing the width and height and spread until the all text appears.

  • How can I add HTML near the </body> tag within a Joomla Module?

    - by Luke
    I am quite new to using Joomla. I have created a custom module, however I would like to add some code near the tag (or near the opening tag) so it is guaranteed to be not nested in any tables whatsoever that might be in the template. I have located details on how to do this within a content plug-in, however I would like to just have the module. Any ideas? Thank you.
