  • how to change picture using drop down list ?

    - by garcon1986
    Hello, I want to use a drop down list, every time i click the content in it, different pictures will show up. But i don't want to use the property 'value', because i want to use the values for other use. Example: <select name='test'> <option value='1'>1</option> <option value='2'>2</option> <option value='3'>3</option> <option value='4'>4</option> </select> How do i accomplish that? Thanks.

  • mailto: anchor links unloading html5 video in Chrome

    - by Robin Pyon
    I have a very simple page with a <video> tag and an email anchor link: http://jsfiddle.net/6GquX/3/ Clicking the email link in Chrome (OS X 10.8 + Win7, 23.0.1271.97) invokes the beforeunloadchange event and causes the video to unload, which isn't the desired outcome. Curiously enough, if I let the video buffer a bit and then click the email link, the video keeps playing and doesn't unload. To my knowledge this only occurs in Chrome and I'm truly at a loss. Visiting any HTML5 video player site (videojs, flowplayer etc), starting a HTML5 video and then immediately simulating an email click with document.location.href = "mailto:[email protected]" in the dev console yields the same error. However, I'm inclined to think it's the way in which the video has been encoded as I'm unable to recreate the above with a video downloaded from YouTube's HTML5 player: http://jsfiddle.net/6GquX/4/ (source) 1. Is it possible that YouTube are encoding their videos in a particular way to combat this? 2. Are there any strategies / hacks I can employ to get around this?

  • getting BR-separated text via DOM in JS/JQuery?

    - by Hellion
    Hi all, I am writing a greasemonkey script that is parsing a page with the following general structure: <table> <tr><td><center> <b><a href="show.php?who=IDNumber">(Account Name)</a></b> (#IDNumber) <br> (Rank) <br> (Title) <p> <b>Statistics:</b> <br> <table> <tr><td>blah blah etc. </td></tr></table></center></table> I'm specifically trying to grab the (Title) part out of that. As you can see, however, it's set off only by a <BR> tag, has no ID of its own, is just part of the text of a <CENTER> tag, and that tag has a whole raft of other text associated with it. Right now what I'm doing to get that is taking the innerHTML of the Center tag and using a regex on it to match for /<br>([A-Za-z ]*)<p><b>Statistics/. That is working okay for me, but it feels like there's gotta be a better way to pick that particular text out of there. ... So, is there a better way? Or should I complain to the site programmer that he needs to make that text more accessible? :-)

  • Binding Events rather than using onclick

    - by Abs
    Hello all, I have been told its better to bind events to elements rather than having onclicks with functions everywhere. I agree with this as it devolves more from the HTML which means cleaner and easier to debug code. But I am having trouble doing this! I loop through some data with PHP (see below) and I currently use onclick to call a function. How can I bind this onclick event to many elements using JQuery. <?php foreach($main_tags as $key=>$value){ ?> <li> <a id="<?php echo $key; ?>" href="#" onclick="tag_search('<?php echo $key; ?>'); return false;"> <?php echo $key; ?> <span class="num-active"> <?php echo $value; ?> </span> </a> </li> <?php } ?> Thanks all for any help

  • [jQuery] Any HTML tags inside of tooltip cause basic tooltip to close on hover.

    - by Christian
    Hi. I'm new to jQuery, in fact any kind of AJAX / JavsScript (although not new to PHP, xHTML and CSS). Anyway I'm trying to achieve a "tooltip-like" effect, where I can hover over a div...the new div fades in above it and then when I exit the div the "tooltip" fades out. So here's the basic jQuery I've managed to scrap together reading the odd guide here and there: $(function() { $('#sn-not-logged-in').hover(function() { $('#sn-not-logged-in-hover').fadeIn('medium'); }); $('#sn-not-logged-in-hover').mouseout(function() { $('#sn-not-logged-in-hover').fadeOut('medium'); }); }); Problem is if I put "any" html tag inside the div that hovers in, the second you roll over it the div fades back out. Any ideas how this can be fixed? Cheers.

  • Creating a textarea with auto-resize

    - by DisgruntledGoat
    There was another thread about this, which I've tried. But there is one problem: the textarea doesn't shrink if you delete the content. I can't find any way to shrink it to the correct size - the clientHeight value comes back as the full size of the textarea, not its contents. The code from that page is below. I'd appreciate any help or pointers. function FitToContent(id, maxHeight) { var text = id && id.style ? id : document.getElementById(id); if ( !text ) return; var adjustedHeight = text.clientHeight; if ( !maxHeight || maxHeight > adjustedHeight ) { adjustedHeight = Math.max(text.scrollHeight, adjustedHeight); if ( maxHeight ) adjustedHeight = Math.min(maxHeight, adjustedHeight); if ( adjustedHeight > text.clientHeight ) text.style.height = adjustedHeight + "px"; } } window.onload = function() { document.getElementById("ta").onkeyup = function() { FitToContent( this, 500 ) }; }

  • How do I override the OK/Cancel button of new list item form in SharePoint?

    - by jlech
    I have a custom list in SharePoint, and I want to override the OK/Cancel buttons that are in the New Item form (The form displayed when you click "New" in the default view of the list). I want the saving logic to remain intact, but I just want to change the default page it redirects to, ideally, to a whole separate page on the site that's not a view of the list. Is there any way I can achieve this? Thanks in advance!

  • Dynamically udpate canvasOverlay property of jQuery jqPlot

    - by You Kuper
    I want to dynamically udpate canvasOverlay property of jQuery jqPlot. This will provide the effect of a timeline in my jqPlot. This effect should be similar to the one shown in this jFiddle. However, instead of drawing points, I want to update canvasOverlay property every second: canvasOverlay: { show: true, objects: [ { rectangle: { xmax: new Date(), xminOffset: "0px", xmaxOffset: "0px", yminOffset: "0px", ymaxOffset: "0px", color: "rgba(0, 0, 0, 0.1)", showTooltip: true } }, ] } How can I do this? What are the functions I should use? UPDATE: My idea is to do something like this: canvasOverlay: { name: 'current', show: true, objects: [ { rectangle: { xmax: new Date(), xminOffset: "0px", xmaxOffset: "0px", yminOffset: "0px", ymaxOffset: "0px", color: "rgba(0, 0, 0, 0.1)", showTooltip: true } }, ] } /... var co = plot.plugins.canvasOverlay; var current = co.get('current'); current.options.objects.rectangle.xmax = new Date(); co.draw(plot);

  • TinyMCE empty link popup

    - by silent1mezzo
    When I try to insert a link using the TinyMCE link plugin all that happens is I get an empty popup box. It continuously tries to load: tiny_mce/utils/mctabs.js tiny_mce/utils/form_utils.js tiny_mce/utils/validate.js tiny_mce/themes/advanced/js/link.js I've seen solutions where you need to edit a config.php file, but I only have the JS version of TinyMCE

    I am using the DataTables plugin for jQuery and need to get one of the table rows. DataTables has a fnGetNodes function that returns an Array with all of the DOMElements of the table. I would like to use a jQuery selector to find that row (I know the id of the row), but I need to convert the Array to a jQuery Object, is this possible?

  • how to use q.js promises to work with multiple asynchronous operations

    - by kimsia
    Note: This question is also cross-posted in Q.js mailing list over here. i had a situation with multiple asynchronous operations and the answer I accepted pointed out that using Promises using a library such as q.js would be more beneficial. I am convinced to refactor my code to use Promises but because the code is pretty long, i have trimmed the irrelevant portions and exported the crucial parts into a separate repo. The repo is here and the most important file is this. The requirement is that I want pageSizes to be non-empty after traversing all the dragged'n dropped files. The problem is that the FileAPI operations inside getSizeSettingsFromPage function causes getSizeSettingsFromPage to be async. So I cannot place checkWhenReady(); like this. function traverseFiles() { for (var i=0, l=pages.length; i<l; i++) { getSizeSettingsFromPage(pages[i], calculateRatio); } checkWhenReady(); // this always returns 0. } This works, but it is not ideal. I prefer to call checkWhenReady just ONCE after all the pages have undergone this function calculateRatio successfully. function calculateRatio(width, height, filename) { // .... code pageSizes.add(filename, object); checkWhenReady(); // this works but it is not ideal. I prefer to call this method AFTER all the `pages` have undergone calculateRatio // ..... more code... } How do I refactor the code to make use of Promises in Q.js?

  • Jquery plugin seems to leak memory no matter what I do

    - by ddombrow
    I've recently been tasked with ferreting out some memory leaks in an application for my work. I've narrowed down one of the big leaks to a jquery plugin. It appears we're using a modified version of a popular context menu jquery plugin. It looks like one of the developers before me attempted to add a destroy method. I noticed it wasn't very well written and attempted to rewrite. Here's the meat of my destroy method: if (menu.childMenus) { for (var i = 0; i < menu.childMenus.length; i++) { $(menu.childMenus[i]).destroy(menu.childMenus[i], 'contextmenu'); } } var recursiveUnbind = function(node) { $(node).unbind(); //$(node).empty().remove(); $.each(node, function(obj) { recursiveUnbind(obj); }); }; $.each(menu, function() { recursiveUnbind(menu); }); $(menu).empty().remove(); In my mind this code should blow away all the jquery event binding and remove the dom elements, yet still the plugin leaks gobs of memory in IE7. The modified plugin with a test page can be found here: http://www.olduglyhead.com/jquery/leaks/ Clicking the button repeatedly will cause IE7 to leak a bunch of memory.

  • CSS + jQuery - Unable to perform .toggle() and repeated jQueryTemplate Item [I must warn you this is a bit overwhelming]

    - by user1027620
    Okay here we go: Stream.html (Template file) <div class="streamItem clearfix"> <input type="button" /> <div class="clientStrip"> <img src="" alt="${Sender}" /> </div> <div class="clientView"> <a href="#" class="clientName">${Sender}</a> <p>${Value}</p> <p>${DateTime}</p> <div class="itemGadgets"> <ul> <li class="toggleInput">Value</li> <li></li> </ul> </div> <div class="inputContainer"> <input type="text" value="" /> </div> </div> </div> <div class="spacer" /> Default.aspx (jQuery) $('.toggleInput').live('click', function () { $(this).parent().parent() .find('.inputContainer').toggle(); $(this).parent().parent().find('.inputContainer') .find('input[type=text]').focus(); }); Update: The above has been changed to: $('.toggleInput').live('click', function () { $(this).closest(".clientView").find(".inputContainer").toggle() $(this).closest(".clientView").find(".inputContainer") .find('input[type=text]').focus(); }); Issues with jQuery: I have comments that belong to each .streamItem. My previous solution was to use ListView control as follows: <ItemTemplate> <asp:Panel ID="StreamItem" CssClass="StreamItem" runat="server"> ... <!-- Insert another nested ListView control here to load the comments for the parent stream. --> So as you can see, this is not a solution since I started using jQuery Templates and I am fetching the data using the following jQuery $.ajax method: $.ajax({ type: 'POST', url: 'Services.asmx/GetStream', data: "{}", contentType: 'application/json', success: function (Stream) { $.get('Templates/Stream.html', function (template) { $.tmpl(template, Stream.d).appendTo("#Stream"); }); } }); How can I resolve this without using the old ListView solution but by using jQuery Templates to load the comments whenever I am getting data for a specific stream? I am using a simple WebMethod to return my data as follows: [WebMethod] public List<Stream> GetStream() { List<Stream> Streams = Stream.GetRange(X, X, HttpContext.Current.User.Identity.Name); return Streams; } I am looking for a way to handle the .toggleInput click event. I need check if .Comments (a main container for the (to be comments container <div>)) has children (or more than one .commentItem). If so, then I need to show that .inputContainer and hide all the other .inputContainer divs with .Comments size() == 0 if they're visible. Please see the image below: Default.aspx (Partial CSS) div.streamItem div.clientView { float : left; width : 542px; } div.streamItem div.clientView p { margin : 5px 0 0 0; font-size : 10pt; } div.streamItem div.clientView div.inputContainer { display : none; /* Doesn't hide .inputContainer */ padding : 2px; background-color : #f1f1f1; } Issues with CSS: On page load, display: none; has no effect. That's it! If you're reading this I'd like to thank you for your time and thoughts! :)

  • Submit multiple forms as one

    - by Stephen Sarcsam Kamenar
    I have two forms on the page. To the user it looks like 1 form, and I actually wish it was one form. But the way I'm trying to reuse code and include things, I can't avoid two forms in the source code... trying to act as one. I don't want to do ajax submit, I want a normal post submit, my form handler has redirects in it. How can I submit both of these, and get values that make sense on the server side. something like $_POST['form1]['whatever'] $_POST['form2]['thing'] Maybe take all the inputs from form 2, rename all of them with a prefix, and append them to form 1? I can't find a non-messy way of doing this. I don't think I need code, just a plan. Least messy idea wins.
