  • How do I add a loading indicator to my page while my iframe loads?

    - by keybored
    I am currently creating a page where upon clicking a link an iframe is inserted into a div and it's contents loaded. I do this using the following jQuery call: $('#mydiv').html('<iframe src="sourcelink.html" frameborder="0" width="760" height="2400" scrolling="no"></iframe>'); Sometimes the source content loads very slowly and, as a result, it looks like nothing is happening. I would like to have a simple loading animation while the content is loading while the iframe's content loads. When the iframe finishes loading it's content should pop in and the loading animation should go away. I've been considering a couple ways I could do this (e.g. having a separate loader div to simply swap the two in and out) but I'm not sure of what the 'best' approach to solving this problem is. Perhaps I shouldn't be using .html()? I'm open to suggestion if there is a more correct solution.

  • Merging getComputedStyle and evaluate in Greasemonkey

    - by Keheliya Gallaba
    I need to get all the text nodes with a certain font-face in a page to an array. I tried.. textnodes = document.evaluate("//* [@style='font-family: foo;']//text()[" + "not(ancestor::script) and not(ancestor::style)]", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); and textnodes = document.evaluate("//* [@face='foo']//text()[" + "not(ancestor::script) and not(ancestor::style)]", document, null, XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null); But these does not work with pages that is styled by external CSS files. Seems getComputedStyle() is the way to go. I think what I need is something like.. var tags = document.getElementsByTagName('*'); for (var i in tags) { var style = getComputedStyle(tags[i], ''); if (style.fontFamily.match(/foo/i)) { textnodes.push(tags[i]); } } But text nodes were not returned in this method. Is there anyway I can use a hybrid of xpath evaluate() and getComputedStyle() or any other way to achieve this?

  • How reference popup object when opener page changes?

    - by achairapart
    This is driving me crazy! Scenario: The main page opens a pop-up window and later calls a function in it: newWin = window.open(someurl,'newWin',options); ...some code later... newWin.remoteFunction(options); and it's ok. Now, popup is still open and Main Page changes to Page 2. In Page 2 newWin doesn't exist anymore and I need to recreate the popup window object reference in order to call again the remote function (newWin.remoteFunction) I tried something like: newWin = open('','newWin', options); if (!newWin || newWin.closed || !newWin.remoteFunction) { newWin = window.open(someurl,'newWin',options); } And it works, I can call newWin.remoteFunction again BUT Safari for some reason gives Focus() to the popup window everytime the open() method is called breaking the navigation (I absolutely need the popup working in the background). Only workaround I can think to solve this is to create an interval in the popup with: if(window.opener && !window.opener.newWin) window.opener.newWin = self; and then set another interval in the opener Page with some try/catch but it is inelegant and very inefficient. so, I wonder, it's really so hard to get the popup object reference between different pages in the opener window?

  • jQuery Running a function in a context and adding to a variable

    - by Mark
    For this question I'm going to give a simplified example of what I want to do, and the function I want to learn to write. var collection = ''; <div id='container'> <span>1</span> <span>2</span> <span>3</span> </div> What I want to do this, for every span in the div, take its text, add it to the collection. So ideally it would look like: $('#container').addtoCollection(collection); The method would be something like: $(this).find('span').each(function () { collection = collection + $(this).text(); }). Where the first this would equal #container. So in the end you can do: console.log(collection); and get: 123 How do I write the function that does this? Thanks!

  • Apache Cordova (Phonegap): is jsop needed for cross-site scripting?

    - by DEX
    I've just started using Apache Cordova. I have an library that makes calls (via ajax) to a soap server. When I run these on my local machine in chrome, I get cross site scripting errors when trying to make calls to the service. When I run the same exact code using the Cordova browser in the iOS emulator, the scripts seem to hit the server fine and the response data is received properly. So my question is how is the Cordova browser able to make these requests without cross-site scripting permissions & JSONP ? One thing I noticed is that when the request is sent from iOS, there is no "Origin" header. Is this allowing the Cordova browser to stealthily circumvent cross-site scripting requirements? Is it possible that the node.js server on the device (I believe this is how Cordova works) is manipulating the headers to allow this? I'd like to avoid enabling cross-site scripting on my site so I think this "feature" is nice, but I'm wondering if it's a security hole as well. Anyone have experience with this?

  • Fluid width Son of Suckerfish dropdown menus

    - by derekerdmann
    For CSS dropdown menus, I usually stick with the Son of Suckerfish dropdowns. The technique works extremely well, but there's one small thing that's always bothered me: the width of the dropdown links is always fixed. Are there any ways to automatically resize the width of the items in a Suckerfish dropdown menu? If not, are there any other CSS-based dropdown menu strategies that can accomplish this?

  • Not very objective - please help

    - by chainwork
    I am having trouble understanding the meaning and more importantly the concept of an object as it relates to jQuery. I understand the basics that its a collection of data that comes in two forms, properties and methods but I kind of get lost on how it works beyond that. Can anyone point me to some good tutorials that maybe helped you understand? I'm hoping to "Get it" once and for all. Many many thanks for your help! =]

  • How can I avoid causing memory leaks in Firefox?

    - by mrdanimal
    It seems that there is a lot of information on memory leaks in IE and how web developers can avoid them, but I can't find much on avoiding leaks in FF. I've found lots of random tips on how end users can tweak their preferences, or tips for extension developers, but little on what I can do as a web developer to make sure my pages don't leak. Am I missing something? It seems lazy to just blame it on the user and say "you've got too many extensions". Or are the major patterns the same as in IE -- circular references and all that? Also, if anyone knows of any tools to troubleshoot leaks in FF, that would be great. I found this: https://addons.mozilla.org/en-US/firefox/addon/2490/ But it's apparently just for chrome and extension development.

  • jQuery Prototype conflict, alternative solutions

    - by lbolognini
    I have a problem as I'm conditionally including the Prototype-based Lightbox script for IE6 as it works better than the jQuery plugin. Of course the two libraries conflict but the official solution is not really feasible for me as i would have to replace tons of $ with the alternative no-conflict syntax. Is there any other solution for me, keeping in mind that in my case it would be easier to have Prototype work nicely with jQuery than the other way around?

    What would be the best way to create a JS chat client with GWT? The bit that I'm having trouble with is the persistence and transfer of the messages. Should I store the messages in a DB and check the db for new messages? Is there a much better way to do this?

  • Building an array out of values from another array

    - by George
    This is a follow up from a question of mine that was just answered concerning parsing numbers in an array. I have an array, data[], with numbers that I'd like to use in a calculation and then put the resulting values into another array. So say data[0] = 100. I'd like to find a percentage using the calculatin, (data[0]/dataSum*100).toFixed(2) where dataSum is the sum of all the numbers in data[]. I've tried: dataPercentage = []; for (var i=0; i < data.length; i++) { data[i] = parseFloat(data[i]); dataSum += data[i]; // looping through data[i] and setting it equal to dataPercentage. dataPercentage[] = (data[i]/dataSum*100).toFixed(2); // thought maybe I was overriding dataPercentage everytime I looped? dataPercentage[] += (data[i]/dataSum*100).toFixed(2); } I also tried just setting dataPercentage = [(data/dataSum*100).toFixed(2)], but I think this creates a nested array, which I don't think is what I need.

  • Can events fired from an iframe be handled by elements in its parent?

    - by allyourcode
    Suppose I have a page located at www.example.com/foo, and it contains an iframe with src="http://www.example.com/bar". I want to be able to fire an event from /bar and have it be heard by /foo. Using the Prototype library, I've tried doing the following without success: Element.fire(parent, 'ns:frob'); When I do this, in ff 3.5, I get the following error: Node cannot be used in a document other than the one in which it was created" code: "4 Line 0 Not sure if that's related to my problem. Is there some security mechanism that's preventing scripts in /bar from kicking off events in /foo?

  • Do I have to duplicate this function? - jQuery

    - by Josh
    I'm using this function to create an transparent overlay of information over the current div for a web-based mobile app. Background: using jQTouch, so I have separate divs, not individual pages loading new. $(document).ready(function() { $('.infoBtn').click(function() { $('#overlay').toggleFade(400); return false; }); }); Understanding that JS will run sequentially when i click the button on the first div the function works fine. When I go to the next div if I click the same button nothing "happens" when this div is displayed, but if i go back to the first div it has actually triggered it on this page. So I logically duplicated the function and changed the CSS selector names and it works for both. But do I have to do this for each use? Is there a way to use the same selectors, but load the different content in each variation?
