I also use i18n for mulitilingual purpose.

  • jQuery - making sure content is loaded before it's faded in?

    - by Kenny Bones
    Hi, Nick Craver really helped me out alot with this code in this thread http://stackoverflow.com/questions/2743443/jquery-can-someone-help-stitching-jquery-code-with-ajaxcomplete/2743791#2743791 And it is working. But I notice that there's a small delay after I've clicked a link and before the content is actually loaded. It's not very intense content that's loaded either so I think it's got something to do with the order which things happen in the script. The original code looks like this: $('.dynload').live('click', function(){ var toLoad = $(this).attr('href')+' #content'; $('#content').fadeOut('fast',loadContent); $('#ajaxloader').fadeIn('normal'); function loadContent() { $('#content').load(toLoad,'',showNewContent()) } function showNewContent() { $('#content').fadeIn('fast',hideLoader()); //Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); } function hideLoader() { $('#ajaxloader').fadeOut('normal'); } return false; }); The new code looks like this: $(function() { $('.dynload').live('click', function(){ $('#ajaxloader').fadeIn('fast'); $('#ajaxloaderfridge').fadeIn('fast'); var href = this.href + ' #content'; $('#content').fadeOut('fast',function() { $(this).load(href,'', function(data) { createMenus(); $('#ajaxloader').fadeOut('fast'); $('#ajaxloaderfridge').fadeOut('fast'); $('#content').fadeIn('fast'); Cufon.replace('h1, h2, h3, h4, .menuwrapper', { fontFamily: 'advent'}); }); }); return false; }); }); $(createMenus); function createMenus() { $('#kontrollpanel .slidepanels').kwicks({ min : 42, spacing : 3, isVertical : true, sticky : true, event : 'click' }); } In the original code, #content is faded out, then the function "loadContent" is started. Which is basically what is happening in the new script as well isn't it? And when I was using the old code, the content just faded out and faded in really fast and smooth and with no small pause delay before the content arrived.

  • how to view associated click function code

    - 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? In above example, i want a way to view that in firebug, or in another way $(this).closest('tr').remove(); If I'm writing in console following, i'm get a link to dom inspector >>> ($('table#users tbody tr:first #save').click) function() but link is for jquery library, not the code i want.

  • 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?

  • Query parameter using JS framework ?

    - by Maxim Veksler
    Hi, I seem to not be able to find implementation from the common Ajax libraries (JQuery, mootools, prototypejs...) that would allow the operation of parsing the window.location.href for request parameter. I would expect something like: $P{"param1"} == "param1_value" Am I missing something? p.s. The web does contains implementation examples for such operations

  • How can I clear content without getting the dreaded "stop running this script?" dialog?

    - by Cheeso
    I have a div, that holds a div. like this: <div id='reportHolder' class='column'> <div id='report'> </div> </div> Within the inner div, I add a bunch (7-12) of pairs of a and div elements, like this: <h4><a>Heading1</a></h4> <div> ...content here....</div> The total size of the content, is maybe 200k. Each div just contains a fragment of HTML. Within it, there are numerous <span> elements, containing other html elements, and they nest, to maybe 5-8 levels deep. Nothing really extraordinary, I don't think. After I add all the content, I then create an accordion. like this: $('#report').accordion({collapsible:true, active:false}); This all works fine. The problem is, when I try to clear or remove the report div, it takes a looooooong time, and I get 3 or 4 popups asking "Do you want to stop running this script?" I have tried several ways: option 1: $('#report').accordion('destroy'); $('#report').remove(); $("#reportHolder").html("<div id='report'> </div>"); option 2: $('#report').accordion('destroy'); $('#report').html(''); $("#reportHolder").html("<div id='report'> </div>"); option 3: $('#report').accordion('destroy'); $("#reportHolder").html("<div id='report'> </div>"); after getting a suggestion in the comment, I also tried: option 4: $('#report').accordion('destroy'); $('#report').empty(); $("#reportHolder").html("<div id='report'> </div>"); No matter what, it hangs for a long while. The call to accordion('destroy') seems to not be the source of the delay. It's the erasure of the html content within the report div. This is jQuery 1.3.2. EDIT - fixed code typo. ps: this happens on FF3.5 as well as IE8 . Questions: What is taking so long? How can I remove content more quickly? Addendum I broke into the debugger in FF, during "option 4", and the stacktrace I see is: data() trigger() triggerHandler() add() each() each() add() empty() each() each() (?)() // <<-- this is the call to empty() ResetUi() // <<-- my code onclick I don't understand why add() is in the stack. I am removing content, not adding it. I'm afraid that in the context of the remove (all), jQuery does something naive. Like it grabs the html content, does the text replace to remove one html element, then calls .add() to put back what remains. Is there a way to tell jQuery to NOT propagate events when removing HTML content from the dom?

  • Why does setting document.domain require me to set it in all popups and iframes too?

    - by Chris
    I'm using a long-polling iframe solution for a chat script. Unfortunately, this requires me to set document.domain='yourdomain.com' in the iframe and main document, because the iframe is a subdomain call. The huge problem is...now all my other scripts that use popups and iframes are broken. They now require me to put document.domain in them too. It does fix it, but this is not an ideal solution at all. Is there another way around this problem?

  • jquery "this" binding issue on event handler

    - by clyfe
    In jquery an event hadler's binding is the event generating DOM element (this points to the dom element). In prototype to change the binding of an event handler one can use the bindAsEventListener function; How can I access both the instance and the DOM element from a event handler? Similar to http://stackoverflow.com/questions/117361/how-can-i-bind-an-event-handler-to-an-instance-in-jquery function Car(){ this.km = 0; $("#sprint").click(this.drive); //setup event handler } // event handler // in it I need to access both the clicked element // and the binding object (instance of car) Car.prototype.drive = function(){ this.km += 10; // i'd like to access the binding (but jq changes it) this.css({ left: this.km }); // also the element // NOTE that is inside this function I want to access them not elsewhere } var car = new Car();

  • Getting req.params in order in Express JS

    - by Adam Terlson
    In Express, is there a way to get the arguments passed from the matching route in the order they are defined in the route? I want to be able to apply all the params from the route to another function. The catch is that those parameters are not known up front, so I cannot refer to each parameter by name explicitly. app.get(':first/:second/:third', function (req) { output.apply(this, req.mysteryOrderedArrayOfParams); // Does this exist? }); function output() { for(var i = 0; i < arguments.length; i++) { console.log(arguments[i]); } } Call on GET: "/foo/bar/baz" Desired Output (in this order): foo bar baz

  • Finding out inside which iframe a script is executing

    - by juandopazo
    I have a page with several iframes. One of this iframes has a page from a different domain. Inside this iframe there's another iframe with a page from the parent domain. my page from mydomain.com -> an iframe -> iframe "#foo" from another-domain.com> -> iframe "#bar" from mydomain.com -> another iframe I need to get a reference to the "#foo" node inside the main page. The security model should allow me to do that because "#bar" has the same domain as the main page. So what I'm doing is iterating through the window.top array and comparing each element to the window object which is currently the "#bar" window object. My test code looks like: for (var i = 0; i < top.length; i++) { for (var j = 0; j < top[i].length; j++) { if (top[i][j] == window) { alert("The iframe number " + i + " contains me"); } } } This works fine in all browsers, but Internet Explorer 6 throws a security error when accesing top[i][j]. Any ideas on how to solve this on IE6? Thanks!

  • Is it possible to create a timer in jscript that you can manually change without it being affected by timezones?

    - by Lixorp
    is it possible to create a timer where I can manually set the hours each day to a set number of hours but still remains accurate? For example; if I set the countdown for 5 hours at 2pm I want the timer to stop as soon as it hits 7pm. Also, when I set the timer for 5 hours I would like everyone in the world to see it countdown from 5 hours, no matter what the time is in their country. In the format: days hours minutes seconds. The reason I want to do this is for a streamer's website. He needs a flexible timer which can be manually changed and is the same worldwide for his viewers to know when he starts streaming. The current timer we're using at the moment; setInterval(function(){ var currentTime = new Date(); if(currentTime.getHours() > 19){ var countdownHours = (24 - currentTime.getHours()) + 19; }else if(currentTime.getHours() < 19){ var countdownHours = 19 - currentTime.getHours(); }else{ var countdownHours = 0; } var countdownMins = 59 - currentTime.getMinutes(); var countdownSecs = 60 - currentTime.getSeconds(); $('#countdown-days h1').text('0'); $('#countdown-hours h1').text(countdownHours); $('#countdown-minutes h1').text(countdownMins); $('#countdown-seconds h1').text(countdownSecs); }, 1000); As you can tell it isn't ideal for what we need it for since it counts down to 7pm in the timezone you're in. Any help/examples would be greatly appreciated, Thank you in advance, Lixorp.

  • Prototype - DOM Traversal with up()

    - by Jason McCreary
    I have the following structure: <form> <div class="content"> ... </div> <div class="action"> <p>Select <a class="select_all" href="?select=1" title="Select All">All</a></p> </div> </form> I am using Prototype's up() to traverse the DOM in order to find the <form> element in respect to the a.select_all. However the following doesn't work: select_link.up('form'); // returns undefined Yet, this does. select_link.up().up().up(); // returns HTMLFormElement Clearly this is an ancestor of a.select_all. The API Docs state Element.up() supports a CSSRule. What am I missing here?

  • [jquery] editableText plugin enabling problem

    - by noName
    Hi, I've been experimenting with this plugin http://valums.com/edit-in-place/, so far so good... But i ran into this problem. I want to update my page when update or new request to save data is sent but if i update this function(edit-in-place) it will add second set of buttons, third, fourth and so on. How could i tell it that it would update just on that returned data, but not all elements? I have an idea it has to do something with each function of jquerys, but I'm not sure as I'm quite new to jquery. Thanks for any help!

  • get js file query param from inside it

    - by vsync
    I load this file with some query param like this: src='somefile.js?userId=123' I wrote the below function in 'somefile.js' file that reads the 'userId' query param but I feel this is not the best approach. Frankly, its quite ugly. Is there a better way? function getId(){ var scripts = document.getElementsByTagName('script'), script; for(var i in scripts){ if( scripts.hasOwnProperty(i) && scripts[i].src.indexOf('somefile.js') != -1 ) var script = scripts[i]; } var s = (script.getAttribute.length !== undefined) ? script.getAttribute('src') : script.getAttribute('src', 2); return getQueryParams('userId',s); };
