  • Suppose i have an HTML table. How do I use JQuery events on this?

    - by alex
    <table> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> <tr class="myRow"><td class="col1"></td><td class="col2"></td></tr> </table> How do I make the appropriate col1 fill with the letters "ABC" when the user rollovers the row? And then disappear the "ABC" when the user moves the mouse away from that row? So far, I got this. I solved it. $(".ep").hover(function(){ $(this).find('td.playButtonCol').html('PLAY'); },function(){ $(this).find('td.playButtonCol').html(''); });

  • HTML5: Can't drag on-the-fly created <div> tag even though draggable='true' Do I need to "BLESS"

    - by Pete Alvin
    After creating a div on the fly with this markup: $('.circuit').prepend("<div class='component' draggable='true'>TRANSISTOR</div>"); It is NOT draggable itself :( Is jQuery prepend() the correct way to create "live" tags in the DOM? Do I need to somehow bless it a different way to make draggable=true really work? How to I wire it up so that on-the-fly divs can be draggable? AFTER NOTE: I added a static div and that is draggable. INTERESTING: I view both the static and dynamic using FireFox F12 Firebug and they are identical. But one is draggable and one is not!!!

  • How to remove one instance of one string in PHP?

    - by Jane
    I have a open source editor on the cms that I am making that automatically inserts a <br /> tag at the beginning of the post it submits to the database. This makes validation a pain, since even though there is no real text being submitted, the form still accepts the break tag as input and prevents the "Please enter some text" error from showing. So I tried to remove the opening break tag by filtering my input like this: substr($_POST['content'], 6); This works as long as the user doesn't press the backspace a couple of times which removes the break tag in which case the first 8 characters of the post gets removed even if they are not a break tag. So how can I remove the first 6 characters of the input ONLY if those first 6 characters are composed of the break tag. Also I don't want to remove all break tags, only the one at the very beginning of the post.

  • After travelling back in Firefox history, javascript won't run.

    - by Patonza
    When I use the back button on Firefox to reach a previously visited page, scripts on that page won't run again. Is there any fix/workaround to have the scripts execute again when viewing the page the second time? Please note that I have tested the same pages on Google Chrome and Internet Explorer and they work as intended. Here are the files and the steps I used to test the problem: (navigate to 0.html, click to get to 1.html, back button) 0.html <html><body> <script type="text/javascript"> window.onload = function() { alert('window.onload alert'); }; alert('inline alert'); </script> <a href="1.html">Click Me!</a> </body></html> 1.html <html><body> <p>Go BACK!</p> </body></html>

  • How to get encoding from MAPI message with PR_BODY_A tag (windows mobile)?

    - by SadSido
    Hi, everyone! I am developing a program, that handles incoming e-mail and sms through windows-mobile MAPI. The code basically looks like that: ulBodyProp = PR_BODY_A; hr = piMessage->OpenProperty(ulBodyProp, NULL, STGM_READ, 0, (LPUNKNOWN*)&piStream); if (hr == S_OK) { // ... get body size in bytes ... STATSTG statstg; piStream->Stat(&statstg, 0); ULONG cbBody = statstg.cbSize.LowPart; // ... allocate memory for the buffer ... BYTE* pszBodyInBytes = NULL; boost::scoped_array<BYTE> szBodyInBytesPtr(pszBodyInBytes = new BYTE[cbBody+2]); // ... read body into the pszBodyInBytes ... } That works and I have a message body. The problem is that this body is multibyte encoded and I need to return a Unicode string. I guess, I have to use ::MultiByteToWideChar() function, but how can I guess, what codepage should I apply? Using CP_UTF8 is naive, because it can simply be not in UTF8. Using CP_ACP works, well, sometimes, but sometimes does not. So, my question is: how can I retrieve the information about message codepage. Does MAPI provide any functions for it? Or is there a way to decode multibyte string, other than MultiByteToWideChar()? Thanks!

  • Is it possible to redirect non-HTML files with HTTP? And chaining redirects?

    - by Earlz
    Hello, I have been thinking about a neat way of load balancing and one thing that would be required is to be capable of loading an image on an HTML page from multiple locations without rewriting the URL(on each load) So what I need to be able to do is have one URL which is the "static" URL. Such as http://example.com/myimage.png The image is not actually contained in example.com though. So example.com does a either a 302 or 301 or 307 HTTP response to cause a redirect to 2.example.com. How do browsers handle this with images like in this situation? Also, how do browsers handle multiple redirections for instance if 2.example.com also didn't contain it and it went to 3.example.com ? (Note, I am asking this because I've never seen a 301 redirect on anything but an HTML page) Also, which status code would be best to use. 301 means "moved permanently" which this "move" isn't permanent so I don't want it cached. Should I use 307? Is that supported by search engines and modern browsers?

  • how to combine these queries

    - by mmcgrail
    and get meaningful results. Currently I am running these three queries: SELECT t.type,t.id,s.title FROM db1.tags t INNER JOIN db1.st s ON s.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='s' ORDER BY tag desc LIMIT 0, 19 SELECT t.type,t.id,v.title FROM db1.tags t INNER JOIN db1.vi v ON v.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='v' ORDER BY tag desc LIMIT 0, 19 SELECT t.type,t.id,i.ca AS title FROM db1.tags t INNER JOIN db2.tablename i ON i.id=t.id WHERE id LIKE '%%' AND t.tag='foo' AND t.type='i' ORDER BY tag desc LIMIT 0, 19 then trying to combine the data results but what I would really prefer is if I could combine them into a single query. Any thoughts?

  • How to show ModelState.AddModelError when the Model is Empty in MVC4

    - by kk1076
    I am displaying a shopping cart. I need to check for empty values in Shopping cart and display a message like "The Shopping Cart is empty". When I use ModelState.AddModelError in myAction, it throws an exception as there is null reference in Model. How to display the ErrorMessage. My Action public ActionResult Index() { string id = Request.QueryString["UserID"]; IList<CartModel> objshop = new List<CartModel>(); objshop = GetCartDetails(id); if (objshop.Count > 0) { return View(objshop.ToList()); } else { ModelState.AddModelError("", "Your Shopping Cart is empty!"); } return View(); } My View @{ @Html.ValidationSummary(true) } <th > @Html.DisplayNameFor(model => model.ProductName) </th> <th > @Html.DisplayNameFor(model => model.Quantity) </th> <th > @Html.DisplayNameFor(model => model.Rate) </th> <th > @Html.DisplayNameFor(model => model.Price) </th> @foreach (var item in Model) { <td> @Html.DisplayFor(modelItem => item.ProductName)</td> <td> @Html.DisplayFor(modelItem => item.Quantity)</td> <td> @Html.DisplayFor(modelItem => item.Rate) </td> <td> @Html.DisplayFor(modelItem => item.Price) </td> } Any suggestions.

  • nginx 0.7.65 rewrite url with querystring problem?

    - by WisdomFusion
    Hi, all Recently, I altered my web server lighty to nginx. And now, Struggling with some problems. First, I have a site in nginx which only rewrites urls and redircts them to a new domain, and this site has exactly no file in its root directory. I put some rewrite rules (just string rules, no querystring) in my nginx.conf list 1 rewrite ^/index_([0-9]+)(.*)$ /forum-$1-1.html last; rewrite ^/dispbbs_([0-9]+)_([0-9]+)\.html$ /thread-$2-1-1.html last; Those rules work perfect till now. However, some rules that used to rewrite url with querystring do not work as hoped. list 2 location /index.asp { if ($arg_boardid ~ "^([0-9]+)") { rewrite ^ /forum-$arg_boardid-1.html break; } rewrite ^ /index.php break; } location /dispbbs.asp { rewrite ^ /thread-$arg_id-1-1.html break; } And, these rules are converted from rules under httpd server, list 3 ^/dispbbs\.asp\?boardID=([0-9]+)&ID=([0-9]+).*$ /thread-$2-1-1.html; ^/dispbbs\.asp\?(.*)&id=([0-9]+)(.*)$ /thread-$2-1-1.html; ^/index\.asp\?boardid=([0-9]+)(.*)$ /forum-$1-1.html; ^/index\.asp\?boardid=([0-9]+)$ /forum-$1-1.html; ^/index\.asp$ /index.php; So, what's the matter with rules listed in the list 2? and how could I make it woking. V/R, gavin

  • ASP Dot Net : How to repeat HTML parts with minor differences on a page?

    - by tinky05
    It's a really simple problem. I've got HTML code like this : <div> <img src="image1.jpg" alt="test1" /> </div> <div> <img src="image2.jpg" alt="test2" /> </div> <div> <img src="image3.jpg" alt="test3" /> </div> etc... The data is comming from a DB (image name, alt text). In JAVA, I would do something like : save the info in array in the back end. For the presentation I would loop through it with JSTL : <c:foeach items="${data}" var="${item}> <div> <img src="${item.image}" alt="${item.alt}" /> </div> </c:foreach> What's the best practice in ASP.net I just don't want to create a string with HTML code in it in the "code behind", it's ugly IMO.

  • Override Maven's default resource filter replacement pattern.

    - by Matt Campbell
    By default maven will filter resources like this: <properties> <replace.me>value</replace.me> </properties> <some-tag> <key>${replace.me}</key> </some-tag> will get you: <some-tag> <key>value</key> </some-tag> Is there a way to override the way maven selects the strings to replace? Specifically, I want to be able to use this: <some-tag> <key>@replace.me@</key> </some-tag> to get the same result as above.

  • Dynamically generate client-side HTML form control using JavaScript and server-side Python code in Google App Engine

    - by gisc
    I have the following client-side front-end HTML using Jinja2 template engine: {% for record in result %} <textarea name="remark">{{ record.remark }}</textarea> <input type="submit" name="approve" value="Approve" /> {% endfor %} Thus the HTML may show more than 1 set of textarea and submit button. The back-end Python code retrieves a variable number of records from a gql query using the model, and pass this to the Jinja2 template in result. When a submit button is clicked, it triggers the post method to update the record: def post(self): if self.request.get('approve'): updated_remark = self.request.get('remark') record.remark = db.Text(updated_remark) record.put() However, in some instances, the record updated is NOT the one that correspond to the submit button clicked (eg if a user clicks on record 1 submit, record 2 remark gets updated, but not record 1). I gather that this is due to the duplicate attribute name remark. I can possibly use JavaScript/jQuery to generate different attribute names. The question is, how do I code the back-end Python to get the (variable number of) names generated by the JavaScript? Thanks.

  • Which templating languages output HTML *as a tree of nodes*?

    - by alamar
    HTML is a tree of nodes, before all. It's not just a text. However, most templating engines handle their input and output as it was just a text; they don't care what happens around their tags, their {$foo}'s and <% bar() %>'s; also they don't care about what are they outputting. Sometimes they happen to produce a correct html, but that's just a coincidence; they didn't aim for that, all they wanted is to replace some funny marks in the text stream with their evaluation. There are a few templating engines which do treat their output as a set of nodes; XSLT and Haml come to mind. For some tasks, this has advantages: for example, you can automatically reformat (like, delete all empty text nodes; auto-indent; word-wrap). The result is guaranteed to be a correct xml/sgml unless you use a strict subset of operations that can break that. Also, such templating engine would automatically quote strings, differently in text nodes and in attributes, because it strictly knows whether you're writing an attribute or a text node. Moreover, it can conditionally remove a node from output because it knows where it does begin and end, which is useful, and do other non-trivial node operations. You might not like XSLT for its verbosiness or functionalness, but it's damn helps that your template is xmllint-able XML, and your output is a good sgml/xml. So the question is: Which template engines do you know that treat their output as a set of correct nodes, not just an unstructured text? I know XSLT, Haml and some obscure python-based one. Moar!

  • What is the appropriate HTML 5 element for a hero unit/showcase?

    - by deb
    A lot of marketing and content-heavy sites showcase the page's primary content using large text and/or images, sometimes with a slider, containing a call to action for signing up for a service, or downloading an app, etc.. I'm not sure what this design element is called, I got the term hero unit from twitter bootstrap: http://twitter.github.com/bootstrap/components.html#typography I think most of you know what I'm trying to describe... If it's not clear I can add screenshots or links to this question. I looked at a few different sites, and some put this hero unit inside a ASIDE element, others use SECTION, ARTICLE and even HEADER. Using twitter bootstrap as an example again: <header class="jumbotron masthead"> <div class="inner"> <h1>Bootstrap, from Twitter</h1> <p>Simple and flexible HTML, CSS, and Javascript for popular user interface components and interactions.</p> <p class="download-info"> Is HEADER the most appropriate tag for this type of content? Or should I use ASIDE, ARTICLE or SECTION?

  • Create function in python to find the highest of all function arguments, and return the "tag" of the value.

    - by gatechgrad
    Consider the following: p1=1; p2=5; p3=7; highest=max(p1,p2,p3). The max function would return 7. I am looking to create a similar function, which would return "p3". I have created a small function (by simple comparisons) for the above example, shown below. however I am having trouble when the number of arguments go up. def highest(p1,p2,p3) if (p1p2) and (p1p3): return "p1" if (p2p1) and (p2p3): return "p2" if (p3p1) and (p3p1): return "p3". Is there a simpler way to do this

  • Rails: Rendered JS file doesn't execute using UJS

    - by Hassinus
    I would like to display a Rails edit form using JS instead of redirecting with HTML. To do this, I use UJS for the edit link: <%= link_to "Edit user info", edit_user_path(1), :remote => true %> Then, the "edit" action of User controller is like this (simplified version): controllers/users_controller.rb: def edit # Step 1: Get the edit HTML form @html = render_to_string(:template => "users/edit.html") # Step 2: Use JS to display the form in the correct place render "users/edit.js" end As you may guess, I have two views: The html version of "edit" action which contains the form in HTML format. Let's consider a test version: views/users/edit.html.erb: <h1>This is just a test</h1> The js version that will display the form in the correct place, using jQuery for example. Again, for test purpose, let's just popup the html text: views/users/edit.js.erb: alert("<%= @html %>"); The problem is that nothing is executed (no popup) Using the inspector (from Chrome web browser), I get the response as text format: alert("<h1>This is just a test</h1>"); Do you have any idea? Why do the rendered JS is not executed? Thanks in advance.

  • Passing a outside variable into a <asp:sqldatasource> tag. ASP.NET 2.0

    - by MadMAxJr
    I'm designing some VB based ASP.NET 2.0, and I am trying to make more use of the various ASP tags that visual studio provides, rather than hand writing everything in the code-behind. I want to pass in an outside variable from the Session to identify who the user is for the query. <asp:sqldatasource id="DataStores" runat="server" connectionstring="<%$ ConnectionStrings:MY_CONNECTION %>" providername="<%$ ConnectionStrings:MY_CONNECTION.ProviderName %>" selectcommand="SELECT THING1, THING2 FROM DATA_TABLE WHERE (THING2 IN (SELECT THING2 FROM RELATED_DATA_TABLE WHERE (USERNAME = @user)))" onselecting="Data_Stores_Selecting"> <SelectParameters> <asp:parameter name="user" defaultvalue ="" /> </SelectParameters> </asp:sqldatasource> And on my code behind I have: Protected Sub Data_Stores_Selecting(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles Data_Stores.Selecting e.Command.Parameters("user").Value = Session("userid") End Sub Oracle squaks at me with ORA-01036, illegal variable name. Am I declaring the variable wrong in the query? I thought external variables share the same name with a @ prefixed. from what I understand, this should be placing the value I want into the query when it executes the select. EDIT: Okay, thanks for the advice so far, first error was corrected, I need to use : and not @ for the variable declaration in the query. Now it generates an ORA-01745 invalid host/bind variable name. EDIT AGAIN: Okay, looks like user was a reserved word. It works now! Thanks for other points of view on this one. I hadn't thought of that approach.

  • How to take html markup from a string and escape it to work within a script?

    - by zac
    I am using wordpress as a CMS and trying to allow user fields to be input to populate the info windows in a Google Map script. I am using this to select the id and pull in the content from a custom field : $post_id = 222; $my_post = get_post($post_id); $snip = get_post_meta($post_id, 'custom-field', true); $permalink = get_permalink( $post_id ); $pass_to = '<div class="content">'.$snip.'</div><div class="moreLink"><a href="'.$permalink.'">Find out more » </a></div></div>'; var point = new GLatLng('<?php echo $lat; $lat; ?>','<?php echo $long; $long; ?>'); var marker = createMarker(point,"<?php echo $mapTitle; $mapTitle; ?>", '<?php echo $pass_to; ?>') map.addOverlay(marker); It works fine unless there is any html in the custom-field which breaks the script. I looked at htmlspcialchar and htmlentities but rather than strip everything out I would like to have it escaped so it still works and the html is intact. Any suggestions? I am pretty new to PHP and would really appreciate any pointers.
