  • dynamic tag count on keyup

    - by rod
    Hi All, I have a div that contains many spans and each of those spans contains a single href. Basically it's a tag cloud. I have a textbox with a keyup event that filters the tag cloud div (It actually just hides the tags if not in filter condition). Is there a way to get a count of the tags shown as the keyup event occurs? Thanks, rodchar

  • Change cursor style in firefox input file tag

    - by JohnJ
    I have been trying to change the cursor style to look like a pointer rather than an I beam thing, but it looks like FF does not respect the cursor spec in an input file field. For example, I have made this small fiddle: http://jsfiddle.net/jDZtn/4/ where Id like the cursor to look like a pointer rather than an Ibeam when the user hovers over it. My end plan is to introduce opacity==0 and use a clickable button over it. I am not sure if this behaviour is a bug or not.

  • how to handle large dataset like sproutcore

    - by Nik
    Hello all, I really don't have any substantial code to show here, actually, that's kinda why I am writing: I looked at the SproutCore demo, especially the Collection demo, on http://demo.sproutcore.com/sample_controls/, and am amazed by its loading 200,000 records to the page so easily. I tried using Rails to provide 200,000 records and in a completely blank HTML page with <% @projects.each do |p| % <%= p.title % <% end % that freezes the browser for seconds on my m1530 laptop with 4gb ram and t7700 256gb ssd. Yet the sproutcore demo does not freeze and takes less than 3 seconds to load. What do you think the one technique they are using to enable this is? Thanks!

  • mootools: $ not defined

    - by eaigner
    I've strange error i don't understand. I'm just moving my code from jQuery over to Mootools because it's much cleaner than the jQuery mess. Now when i use the $$('div.canvas') in mootools i get the correct element. When i try $(document).getElement('div.canvas') it tells me that $ is not defined. How can $$ and all helper functions like $lambda etc. be defined but not $? Has something changed there from 1.1 to 1.2 and the docs are not updated yet?

  • Reference an object, based on a variable with it's name in it

    - by James G
    I'm looking for a way to reference an object, based on a variable with it's name in it. I know I can do this for properties and sub properties: var req = {body: {jobID: 12}}; console.log(req.body.jobID); //12 var subProperty = "jobID"; console.log(req.body[subProperty ]); //12 var property = "body"; console.log(req[property][subProperty]); //12 is it possible for the object itself? var req = {body: {jobID: 12}}; var object = "req"; var property = "body"; var subProperty = "jobID"; console.log([object][property][subProperty]); //12 or console.log(this[object][property][subProperty]); //12 Note: I'm doing this in node.js not a browser. Here is an exert from the function: if(action.render){ res.render(action.render,renderData); }else if(action.redirect){ if(action.redirect.args){ var args = action.redirect.args; res.redirect(action.redirect.path+req[args[0]][args[1]]); }else{ res.redirect(action.redirect.path); } } I could work around it by changing it to this, but I was looking for something more dynamic. if(action.render){ res.render(action.render,renderData); }else if(action.redirect){ if(action.redirect.args){ var args = action.redirect.args; if(args[0]==="req"){ res.redirect(action.redirect.path+req[args[1]][args[2]]); }else if(args[0]==="rows"){ rows.redirect(action.redirect.path+rows[args[1]][args[2]]); } }else{ res.redirect(action.redirect.path); } }

  • Rendering ExtJs components without panels?

    - by Tower
    Hi, Take a look at this example: http://www.extjs.com/deploy/dev/examples/multiselect/multiselect-demo.html On it, there are components rendered against a panel. I've been searching for a way to render components without a panel, so that they are laid out against empty background directly, without any window-like panels. Is there a way to accomplish this?

  • jQuery: Freezing/Disabling all events temporarily?

    - by Legend
    I have the following usecase: A div with some buttons When the user clicks on a button, a popup is shown and the background div is faded out to 0.5 opacity The problem is that when the popup comes in, the user is still able to click on the background buttons. At this point, I can remove the entire DIV temporarily but I don't want to do that. Is there anyway I can disable all the previously attached events and then add event handlers ONLY to the current popup? (I mean something like a close button should still work on a popup) Any suggestions?

  • HTML and jQuery anchoring

    - by Wayne
    Whenever the url contains the div id, it would obviously go down to the div when the URL has: http://domain.com.faq.php#1 <div id="1">Bla bla bla</div> But what I like is to have same feature of Stackoverflow, when you click on an answer in your messages, it will scroll down to the page and has that fadeOut effect on the answer. How do I do this?

    - by llamerr
    For example, i associate following function with some element $('table#users tbody tr:first #save').click(function(){ $(this).closest('tr').remove(); }); Now, if i don't know where this function is stored, is there a way to view associated with click() code?

  • prevent form from automatically re-submitting on page load

    - by user323774
    I am using jQuery to point a form's target to an iframe on .submit(). This is to upload a file. It works fine, but when the page reloads, and the iframe is appended to the DOM, the iframe automatically resubmits the form, causing the same file to be sent to the server on each page load. If I do not include the iframe in the HTML markup, or do not append it to the DOM, this doesn't happen, but of course, I need the iFrame. So my question is, how can i prevent this? :) Andrew

  • Why does a checkbox remain checked in FF3 but not in IE, Chrome or ...

    - by sirrocco
    So - I have a checkbox <asp:CheckBox ID="chkOrder" runat="server" Visible='<%#IsCheckBoxVisible() %>' Checked="false" OnCheckedChanged="chkOrder_CheckedChanged" AutoPostBack="true" EnableViewState="false"></asp:CheckBox> the one above. Now, the checkbox is in a gridview and on databound - for all the rows in the gridview the checkbox is set to false. The problem is that the first checkbox is still true checked. In IE the problem doesn't exist, same for Chrome. I'm running out of options. Also if i use $("checkboxName").attr("checked"); // verified on jquery ready function. In FF it is true; IE false; Chrome false. Any tips? EDIT Now get ready for this : in the generated html - there is NO checked attribute. The diff between FF and IE is exactly the same. Another thing - the grid that contains the checkboxes has an ajax panel on it and when I page the grid, try to go to page 2 - the checkedChanged in codebehind is triggered.
