  • Using HTML Canvas for UI elements?

    - by Tower
    Hi, I have a couple of UI elements such as buttons in my web application. I was going to use CSS3's transitions to animate the transition from one background-image to another. I figured out that it's not possible with the current transitions draft at least. So, I was wondering if it would make sense to use Canvas as the button. I'm sure it can handle events, so, I see no problems here. Are there any?

  • Cross-Origin Resource Sharing (CORS) - am I missing something here?

    - by David Semeria
    I was reading about CORS (https://developer.mozilla.org/en/HTTP_access_control) and I think the implementation is both simple and effective. However, unless I'm missing something, I think there's a big part missing from the spec. As I understand, it's the foreign site that decides, based on the origin of the request (and optionally including credentials), whether to allow access to its resources. This is fine. But what if malicious code on the page wants to POST a user's sensitive information to a foreign site? The foreign site is obviously going to authenticate the request. Hence, again if I'm not missing something, CORS actually makes it easier to steal sensitive information. I think it would have made much more sense if the original site could also supply an immutable list of servers its page is allowed to access. So the expanded sequence would be: 1) Supply a page with list of acceptable CORS servers (abc.com, xyz.com, etc) 2) Page wants to make an XHR request to abc.com - the browser allows this because it's in the allowed list and authentication proceeds as normal 3) Page wants to make an XHR request to malicious.com - request rejected locally (ie by the browser) because the server is not in the list. I know that malicious code could still use JSONP to do its dirty work, but I would have thought that a complete implementation of CORS would imply the closing of the script tag multi-site loophole. I also checked out the official CORS spec (http://www.w3.org/TR/cors) and could not find any mention of this issue.

  • Using input type="submit" to change content

    - by Conti
    Okay, I'm pretty sure I'm missing something very obvious here, but I just couldn't find a proper solution so far. What I'm trying to do is simple: Have a user write something into a form, have him submit the form, and write that input into a textarea on the same page. This is my code: <html><head></head> <body> <form name='registration'> <label for="input">Input:</label> <input type="text" id="input"/> <input type="submit" id="submit" value="Submit" onclick="execute()"/> </form> <div id="results"> <span>Result</span> <span><textarea cols="30" rows="5" id="resulttext" readonly="readonly"></textarea> </span> </div> <script> function execute() { var result = document.getElementById("input").value document.getElementById("resulttext").value=result; } </script> </body> </html> Now what happens if I enter something into the form is that the textarea briefly shows my input before reverting back to showing nothing. My guess is that the textarea field is only changed for the duration of the execute() function. When I change input type="submit" to a <button> everything works as intended, but I'm pretty sure I'm not supposed to do that.

  • Dragged div change places with destination

    - by Cudos
    Hi. Maybe a bit complex to explain. I have a grid with 9 images 100 x 100 px like this (each number symbolize a picture): 1 2 3 4 5 6 7 8 9 What I want is that the user can drag and drop e.g. 9 over 1 and they change places like this: 9 2 3 4 5 6 7 8 1 Sortables from jquery UI will not work since their solution is using floats. That will "push" all the boxes to the right or left e.g.: 9 1 2 3 4 5 6 7 8 thanks in advance.

  • JQuery class selectors like $(.someClass) are case sensitive?

    - by Justin Grant
    Given this HTML: <div class="OpenIDSelector">some text</div> Why does this JQuery selector match it on some browsers and some pages, but not on others? $('.OpenIdSelector) NOTE: I ran into this problem and solved it myself, but it was annoying and I didn't find it on StackOverflow already, so I'm posting it as a Q&A pair so someone else won't waste an hour like I did.

  • sub menu border calls onmouseout event

    - by insanepaul
    I've created a simple menu and submenu with tags(not allowed to use ul elements). To access the submenu the user hovers their mouse over the menu item. I use the onmouseover and onmouseout events to either show or hide the sub menu depending on which item is selected. A pipe (|) is used to seperate each submenu item and this is what is causing me problems. When a user hovers their mouse above the pipe character the subMenu div calls the onmouseout event which is not what I want. So I added padding around the pipe character and a minus margin so that there were no gaps between the pipe character and the other elements. This worked for all browsers including IE8. But in IE7 (I haven't tested IE6 yet) the submenu div calls the onmouseout event when I touch the top bit of either the left or right border of the pipe character span element. <div id="subMenu" onmouseout="hideSubMenu()" > <div id="opinionSubMenu" onmouseover="showOpinionSubMenu()"> <a id="Blogs" href="HTMLNew.htm">BLOGS</a> <span class="SubMenuDelimiter">|</span> <a id="Comments" href="HTMLNew.htm">COMMENTS</a> <span class="SubMenuDelimiter">|</span> <a id="Views" href="HTMLNew.htm">VIEWS</a> </div> <div id="learningSubMenu" onmouseover="showLearningSubMenu()"> <a id="Articles" href="HTMLNew.htm">ARTICLES</a> <span class="SubMenuDelimiter">|</span> <a id="CoursesCases" href="HTMLNew.htm">COURSES & CASES</a> <span class="SubMenuDelimiter">|</span> <a id="PracticeImpact" href="HTMLNew.htm">PRACTICE IMPACT</a> </div> </div> This is my css class #subMenu{ padding:10px 0px; background-color:#F58F2D; font-weight:normal; text-decoration:none; font-family:Lucida Sans Unicode; font-size:14px; float:left; width:100%; display:none;} #Blogs, #Comments, #Views, #Articles { padding:10px 5px; background:none repeat scroll 0 0 transparent; color:#000000; font-weight:normal; text-decoration:none; border:solid 1px black;} #Blogs:hover, #Comments:hover, #Views:hover, #Articles:hover{ color:#ffffff; text-decoration:none;} .SubMenuDelimiter{ padding:10px 5px; margin:10px -5px;}

    - by 0plus1
    I'm looking to direct the user on the channell webpage instead of the video url that I'm embedding. I've read the api and I didn't see any way to achieve this. I tried enclosing the embedded video in a and I added this code: $('#youtube').click(function() { document.write('http://www.youtube.com/user/trasportareoggi'); return false; }); And surprise it won't work. How, if it's even possible I can do this?

  • In 2011 is it truly necessary to still degrade js?

    - by 0plus1
    Serious question. I tried most of the famous websites (including facebook) and I can say that tons of functionality doesn't degrade at all with js disabled. I've been always told that js should degrade gracefully, but does this still applies in these day and age? ie6 support is being dropped by several sites, and most of the web2.0 relies heavily on js (especially ajax, I even found some sites that doesn't let you login without js enabled). What are your thought about it?

  • Get computed font size for DOM element in JS

    - by Pekka
    Is it possible to detect the computed font-size of a DOM element, taking into consideration generic settings made elsewhere (In the body tag for example), inherited values, and so on? A framework-independent approach would be nice, as I'm working on a script that should work standalone, but that is not a requirement of course. Background: I'm trying to tweak CKEditor's font selector plugin (source here) so that it always shows the font size of the current cursor position (as opposed to only when within a span that has an explicit font-size set, which is the current behaviour).

  • How can chunks be allocated in a node.js stream in object mode all at once?

    - by Quentin Engles
    I can see how buffers, and strings can be sent as chunks, but I'm having a problem thinking about how streams can be dealt when working in object mode. Say I have a byte stream from an http request message. I want to take that message, parse, and then transform it into one big object. I already know how to parse the message. What I'm wondering is if the message is big so it has many chunks, but I want to make one object for the output how can I make sure the data event waits for the whole thing? Is this just a matter of not using the push method until the chunked data has finished being sent? That would then restrict the stream data output to a smaller object which I think I'm fine with for now. As an added condition the larger data will be reduced in size after the the transform.

  • Resize jqGrid based on number of rows?

    - by Rosdi
    I want my jqGrid to shrink and expand based on the number of rows it has. Let say it currently has 10 rows, the height of the jqGrid will shrink to 10 rows (so that no gaping empty rows is exposed). If however there are too many rows, the height of the grid will expand to a maximum 'height' value and a scroll bar will appear.
