  • Prototype mouseleave for two elements

    - by TenJack
    I have created a small navigation element that is positioned right on top of another element. It is only shown when a user mousenters/mouseovers the main element. I am having some trouble with the prototype. I would like this small nav element to be hidden when a user mouses out of the main box, but I would also like the small nav element to remain visible if a user mouses out of the main box but mouses into the small nav at the same time. This is my attempt so far with some pseudo-code to hopefully explain: $('main_box').observe('mouseenter', function(){ $('small_div').show() }) $('main_box').observe('mouseleave', function(){ if this element is $('small_div') then Event.stop() $('small_div').observe('mouseleave', function(){ if this element is $('main_box') Event.stop observe $('main_box') mouseleave else $('small_div').hide(); }) else $('small_div').hide(); }) The main thing I'm having trouble with is figuring out what element the mouse is over at a given point in time. Is there a way to do something like: on mouseleave do blah unless the mouse is over a specific element then do not do blah?

  • functions inside or outside jquery document ready

    - by Hans
    Up until now I just put all my jQuery goodness inside the $(document).ready() function, including simple functions used in certain user interactions. But functions that don´t require the DOM document to be loaded or are only called afterwards anyway, can be placed outside the $(document).ready() as well. Consider for example a very simple validation function such as: function hexvalidate(color) { // Validates 3-digit or 6-digit hex color codes var reg = /^(#)?([0-9a-fA-F]{3})([0-9a-fA-F]{3})?$/; return reg.test(color); } The function is only called from within the $(document).ready() function though. What is best practice (syntax, speed); placing such a function inside or outside the jquery document ready function?

  • jquery tooltip shows a div's content

    - by bob
    Hello, I want to use either http://onehackoranother.com/projects/jquery/tipsy/ or http://bassistance.de/jquery-plugins/jquery-plugin-tooltip/ and I was wondering if lets say I have a div on my page that has a class 'item_info'. Can I have my tooltip that is created output the div inside the tooltip and formatted properly according to my css? Is there another plugin I should be looking into? Thanks. I hope this is clear enough.

  • Javscript filter vs map problem

    - by graham.reeds
    As a continuation of my min/max across an array of objects I was wondering about the performance comparisons of filter vs map. So I put together a test on the values in my code as was going to look at the results in FireBug. This is the code: var _vec = this.vec; min_x = Math.min.apply(Math, _vec.filter(function(el){ return el["x"]; })); min_y = Math.min.apply(Math, _vec.map(function(el){ return el["x"]; })); The mapped version returns the correct result. However the filtered version returns NaN. Breaking it out, stepping through and finally inspecting the results, it would appear that the inner function returns the x property of _vec but the actual array returned from filter is the unfiltered _vec. I believe my usage of filter is correct - can anyone else see my problem?

  • Resources for looking up differences in rendering behavior between web-browsers and browser bugs

    - by ICodeForCoffee
    I recently encountered a printing issue in Firefox that eventually turned out to be a problem with the fieldset tag we wrapped the entire page in. (Bugzilla: Bug 471015) All browsers have their own rendering quirks and issues, but it can be very hard to know what's causing different behaviors. Sure, you can Google, but that's often taking a shot in the dark about what you think is causing the problem. It also doesn't stop you from having to sort through multiple complains about the same behavior before you find someone who has the issue your looking for. Are there any websites out there that let you search for rendering behavior issues by browser version, browser function, css tag, or html tag? I've seen this SO Question, Wanted: Resource for documented Cross-Browser differences, but I'd like to find something more detailed that includes browser bugs.

  • Accessing contents of NativeWindow in a HTML AIR application?

    - by Dan Scotton
    I'm currently building a HTML/JS AIR application. The application needs to display to the user a different 'window' - dependant on whether this is the first time they've launched the application or not. This part is actually fine and I have the code below to do that: if(!startUp()) { // this simply returns a boolean from a local preferences database that gets shipped with the .air // do first time stuff var windowOptions = new air.NativeWindowInitOptions(); windowOptions.systemChrome = 'none'; windowOptions.type = 'lightweight'; windowOptions.transparent = 'true'; windowOptions.resizable = 'false'; var windowBounds = new air.Rectangle(300, 300, 596, 490); var newHtmlLoader = air.HTMLLoader.createRootWindow(true, windowOptions, true, windowBounds); newHtmlLoader.load(new air.URLRequest('cover.html')); } else { // display default window // just set nativeWindow.visible = true (loaded from application.xml) } However, what I want to be able to do is manipulate the html content from within cover.html after it has loaded up. There seems to be plenty of tutorials online of how to move, resize, etc. the NativeWindow, but I simply want access to the NativeWindow's HTML content. For example, how would I add a new paragraph to that page? I've tried the following: newHtmlLoader.window.opener = window; var doc = newHtmlLoader.window.opener.document.documentElement; Using AIR's Introspector console, ....log(doc) returns [object HTMLHtmlElement]. Hmm, seems promising right? I then go on to try: var p = document.createElement('p'); var t = document.createTextNode('Insert Me'); p.appendChild(t); doc.appendChild(p); ...but nothing gets inserted. I've also tried the following replacements for doc: var doc = newHtmlLoader.window.opener.document.body; // .log(doc) -> [object HTMLBodyElement] var doc = newHtmlLoader.window.opener.document; // .log(doc) -> Error: HIERARCHY_REQUEST_ERR: DOM Exception 3 ...as well as the following with jQuery: $(doc).append('<p>Insert Me</p>'); // again, nothing So, anyone had any experience in accessing a NativeWindow's inner content programmatically? Any help will be greatly appreciated.

  • Get all Select Elements in a Form by referencing $(this) instead of $("form select")

    - by DaveDev
    Hi Guys I'm currently getting all the Select elements that exist in a form with the following: $("form").submit(function(event) { // gather data var data = GetSelectData($("form select")); // do submit $.post($(this).attr("action"), data, ..etc) }); Instead of passing in $("form select"), is there a way I can say something like $(this).children('select') // this doesn't work, btw to get all the select elements that exist within the context of the form the submit event is executing for? This will allow me to reduce my code to the following, moving all the functionality into a common function: $("form").submit(function(event) { GatherDataAndSubmit($(this)); }); function GatherDataAndSubmit(obj) { var data = GetSelectData(obj.children('select')); $.post(obj.attr("action"), data, ..etc) } Thanks Dave

  • Is it possible to wrap an asynchronous event and its callback in a function that returns a boolean?

    - by Rob Flaherty
    I'm trying to write a simple test that creates an image element, checks the image attributes, and then returns true/false. The problem is that using the onload event makes the test asynchronous. On it own this isn't a problem (using a callback as I've done in the code below is easy), but what I can't figure out is how to encapsulate this into a single function that returns a boolean. I've tried various combinations of closures, recursion, and self-executing functions but have had no luck. So my question: am I being dense and overlooking something simple, or is this in fact not possible, because, no matter what, I'm still trying to wrap an asynchronous function in synchronous expectations? Here's the code: var supportsImage = function(callback) { var img = new Image(); img.onload = function() { //Check attributes and pass true or false to callback callback(true); }; img.src = 'data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs='; }; supportsImage(function(status){ console.log(status); }); To be clear, what I want is to be able to wrap this in something such that it can be used like: if (supportsImage) { //Do some crazy stuff } Thanks! (Btw, I know there are a ton of SO questions regarding confusion about synchronous vs. asynchronous. Apologies if this can be reduced to something previously answered.)

  • jQuery: Moving window (or FIFO) type DIV?

    - by Legend
    I have been trying to get this effect for a couple of hours now and I must admit I am failing at it. I am trying to construct a DIV that accepts a particular number of items (say 5), when the 6th item is added, the first item that was aded should be removed (first-in-first-out). The feel should have some kind of a fadeIn and fadeOut. Here's what I managed to write till now: ... //Create a ul element with id 'ulele' and add it to a div ... //Do an ajax call and when an element arrives Hash = ComputeHash(message) if(!$("#" + Hash).exists()) { var element = $("<li></li>").html(message).attr('id', Hash).prependTo("#ulele"); $("#" + Hash).hide().delay(10000 - 1000 * messageNumber).show("slow"); _this.prune("#ulele"); } ... prune: function(divid) { $("#" + divid).children().each( function(i, elemLi) { if(i >= maxMessages) $(this).delay(10000).hide("slow").delay(10000).remove(); } ); } I've tried a couple of variations but the final effect I am getting is not that of a FIFO. The elements disappear instantaneously despite the delay and hide("slow") calls. Anyone has a more straightforward approach?

  • What does the MS Ajax Framework use location.hash for?

    - by DDaviesBrackett
    I've noticed that the MS ajax framework touches the action of the default form during Sys.Application.initialize, appending location.hash to it. This is interfering with other code in my app that expects different behaviour. What does the framework do with that? It refers to the values it puts on the hash as 'state', but how do I find out what it's communicating and from where?

  • CSS Pseduo-selectors and IE

  • How do you make an image opened in colorbox scrollable

    - by nicholas.alipaz
    I would like my images that I open in colorbox to be displayed fullsize with no resizing applied to them and then apply scrollbars to allow for viewing the larger images. Some of my images are quite tall and things get pixelated when resized down. Currently colorbox just resizes my images down to the size of the available height/width. Is there a way to make all images display fullsize with overflow scrollable in colorbox? I am linking directly to an image: <a href="/myimage.png" title="My Image" class="colorbox imagefield imagefield-imagelink imagefield-field_portfolio_screenshot initColorbox-processed cboxElement" rel="gallery-12"> <img src="/thumb/myimage.png" alt="image" title="My Image" class="imagecache imagecache-portfolio_screenshot_thumb" height="50" width="50"> </a>

  • JS: Why isn't this variable available to the other functions?

    - by Marius Jonsson
    Hello there, I've am trying to make a canvas animation: var context; var meter; var pin; function init() { var meter = new Image(); var pin = new Image(); var context = document.getElementById('canvas').getContext('2d'); meter.src = 'background.png'; pin.src = 'needle.png'; context.drawImage(meter,0,0); context.translate(275,297); context.save(); setTimeout(startup,500); } function startup() { var r=2; // set rpm here. var i=r*36-27; var angleInRadians = 3.14159265 * i/180; //converting degree to radian context.rotate(angleInRadians); //rotating by angle context.drawImage(pin,-250,-3); //adjusting pin center at meter center context.restore(); } You can see the script at http://www.kingoslo.com/instruments/ With firebug I get error saying that context is undefined, which I think is strange. Thanks. Kind regards, Marius

  • Need some help with onClick and an if/else issue...

    - by Adam
    I have a menu with seven items. If you click the first item, div one shows. If you click any other item (2 through 7) div two shows. That's what I'm looking to do. I'm new at all this but am pretty sure it's an if/else function, such that if I click on <a id="1">, show the first div, else show the second div. I suppose I can do a hide/show to get back to the first div. I'm going to keep poking around, but if I can't find it, any help is surely appreciated.

  • Help with manipulating child/parent elements with jQuery

    - by Mohammad
    Currently I have this JQuery script var img = $(this); img.wrap('<div class="photo"></div>'); img.parent().append("<p>" + img.attr("alt") + "</p>"); which successfully turns the following: <img src="photo.jpg" alt="caption"> into this <div class="photo"> <img src="photos.jpg" alt="caption"/> <p>caption</p> </div> All is well unless the image has a link as a parent; <a href="#"><img since I want it to be correct html (I'm fussy) improving the resulting outcome bellow would be satisfactory <a href="#"> <div class="photo"> <img src="photos.jpg" alt="caption"/> <p>caption</p> </div> </a> to this: <div class="photo"> <a href="#"> <img src="photos.jpg" alt="caption"/> </a> <p><a href="#">caption</a></p> </div> </a> This is my jQuery script so far (which doesn't work bc I'm a noob) aha if(img.parent('a')){ var targetLink = img.parent('a').attr('href').val(); img.parent('a').wrap('<div class="photo"></div>'); img.parent('div').append('<p><a href="'+targetLink+'">' + img.attr("alt") + '</p></a>'); }else{ img.wrap('<div class="photo"></div>'); img.parent().append("<p>" + img.attr("alt") + "</p>"); }; Any advice, or help will be greatly appreciated : ) Thank You! Update *Answer* (works but looks sloppy) I'm editing it atm; if(img.parent('a').length){ var targetLink = img.parent().attr('href'); img.parent().wrap('<div class="photo"></div>'); var divTarget = img.parent('a').parent('div'); divTarget.append('<p><a href="'+targetLink+'">' + img.attr("alt") + '</p></a>'); }else{ img.wrap('<div class="photo"></div>'); img.parent().append("<p>" + img.attr("alt") + "</p>"); };

  • Checking if radio buttons are checked in Firefox

    - by Andrew Song
    On my site, I have two checkboxes created in my ASP.NET MVC view like so: Html.RadioButton("check", "true", "true" == (string) ViewData["someKey"], new { id = "check1"}); Html.RadioButton("check", "false", "false" == (string) ViewData["someKey"], new { id = "check2"}); I am positive that ViewData["someKey"] has the value "true" in it. In my JS init function, I perform the following check: alert($('#check1').is(':checked') + " " + $('#check2').is(':checked')); In Firefox (and only Firefox), my alert dialog will show the following (it works as expected in every other browser): Initial page load: true false Normal refresh via Ctrl + R: false false Refresh skipping cache via Ctrl + Shift + R: true false I have tried many different methods of looking at the checkbox value, including $('#check1').attr('checked') without success. If I examine the HTML in Firebug, I can see that the first radio button has the property checked="checked" in it. Why is the checkbox value changing in FF when I refresh, and how can I mitigate this? Since this seems to be a FF-only bug, how can I change my code to make it work? This SO question seemed to ask something similar, but none of the proposed solutions seem to work in this case. Edit: I should also point out that when the radio button is rendered after the refresh in FF, it's not actually being displayed as checked either, despite what the HTML is telling me. Edit2: Adding raw HTML as per request <input id="check1" type="radio" value="True" name="check" checked="checked"/> <input id="check2" type="radio" value="False" name="check"/>

  • 'Fixed' for loop - what is more efficient?

    - by pimvdb
    I'm creating a tic-tac-toe game, and one of the functions has to iterate through each of the 9 fields (tic-tac-toe is played on a 3x3 grid). I was wondering what is more efficient (which one is perhaps faster, or what is the preferred way of scripting in such situation) - using two for nested loops like this: for(var i=0; i<3; i++) { for(var j=0; j<3; j++) { checkField(i, j); } } or hard-coding it like this: checkField(0, 0); checkField(0, 1); checkField(0, 2); checkField(1, 0); checkField(1, 1); checkField(1, 2); checkField(2, 0); checkField(2, 1); checkField(2, 2); As there are only 9 combinations, it would be perhaps overkill to use two nested for loops, but then again this is clearer to read. The for loop, however, will increment variables and check whether i and j are smaller than 3 every time as well. In this example, the time saving at least might be negligible, but what is the preferred way of coding in this case? Thanks.
