  • closure not working

    - by dorelal
    var Dog = function() { var _instance = 'hello world'; return function() { console.log(this._instance); } } (); //note that it is self invoking function var l = new Dog(); //#> undefined In the above case I was expecting output of 'hello world'. Why this._instance is not accessing the the varible which should be accessible by virtue of closure. I tested this in FF and am getting undefined.

  • jQuery animate opacity doesn't work properly on IE

    - by fidoboy
    I'm trying to use animate function to change the height and opacity for a DIV. The div has a image background in CSS, it works fine on Firefox and Safari, but when i test it on IE the background is being removed. This is my code: if (jQuery.support.opacity) { jQuery('#list_box').animate({opacity: '1',height: '300px',top: newTop},{duration: 300}); } else { jQuery('#list_box').animate({filter: 'alpha(opacity=100)',height: '300px',top: newTop},{duration: 300}); } How can i fix it?

  • How to match !x but not !!x in JS regex?

    - by mpeterson
    Given the following text: This is!!xa simple string!xpattern I would like to get a regexp that matches the !x that's between "string" and "pattern" but not !!xa that's between "is" and "a". This regexp is to be used inside a string split(). I have tried several combinations but I cannot get a regexp that meets my needs. Perhaps my expression is not so regular after all =) Thanks in advance!

  • Iterating Through N Level Children

    - by bobber205
    This seems like something neat that might be "built into" jQuery but I think it's still worth asking. I have a problem where that can easily be solved by iterating through all the children of a element. I've recently discovered I need to account for the cases where I would need to do a level or two deeper than the "1 level" (just calling .children() once) I am currently doing. jQuery.each(divToLookAt.children(), function(index, element) { //do stuff } ); This is what I'm current doing. To go a second layer deep, I run another loop after doing stuff code for each element. jQuery.each(divToLookAt.children(), function(index, element) { //do stuff jQuery.each(jQuery(element).children(), function(indexLevelTwo, elementLevelTwo) { //do stuff } ); } ); If I want to go yet another level deep, I have to do this all over again. This is clearly not good. I'd love to declare a "level" variable and then have it all take care of. Anyone have any ideas for a clean efficient jQueryish solution? Thanks!

  • onclick from an Object's button doesn't work

    - by 730
    I instantiate an object, with an argument which is a button. When the button of an instance is clicked, it should run a function, but it doesn't. In the full version of the code, Chrome gives this message in the console: "Uncaught TypeError: Cannot read property 'onclick' of undefined" HTML: <textarea id='txt' readonly rows='5' cols='40'></textarea> <button id='btn' type='button'>click</button> JS: var btn = document.getElementById('btn'); var txt = document.getElementById('txt'); var foo = new Foo(btn); function Foo(btn) { this.button = btn; } Foo.prototype.buy = function() { txt.value = 'Foo Bar'; }; Foo.button.onclick = function() { foo.buy(); }; Fiddle

  • jQuery reader() on downloaded content.

    - by David
    Hi all! jQuery.ready() allows us to wait for the construction of the webpage. Recently it has been added support to wait until CSS files are loaded. I would like to know if that feature can be used for downloaded content, because I fetch content via $.ajax() that holds CSS references and I would like to retrieve the content of the CSS before working with the retrieved content. Fetch with $.ajax() the html. -- Wait until all CSS is downloaded. Show to fetched content (already css'ed). Thank you very much for your help.

  • jQuery Nested Droppables

    - by John
    I have a nested set of jQuery droppables...one outer droppable that encompasses most of the page and an a set of nested inner droppables on the page. The functionality I want is: If a draggable is dropped outside of any of the inner droppables it should be accepted by the outer droppable. If a draggable is dropped onto any of the inner droppables it should NOT be accepted by the outer droppable, regardless of whether the inner droppable accepts the draggable. So that would be easy if I could guarantee 1+ inner droppables would accept the draggable, because the greedy attribute would make sure it would only get triggered once. Unfortunately the majority of the time the inner droppable will also reject the draggable, meaning the greedy option doesn't really help. Summary: The basic functionality is a set of valid/invalid inner droppables to accept the draggable, but when you toss the draggable outside any of the draggables it gets destroyed by the outer droppable. What's the best way of doing this?

Any ideas why this doesn't work on IE6? $('#button_holder').html('<a href="#" onclick="run_activity_upload(); return false;" id="save_button">Upload</a>'); Thanks, Abs

  • Getting a Script Error Every Time I Click a Link

    - by Flip4Life
    I have everything working perfectly on my site, but for some reason, I get an error message in console whenever I click a link anywhere on my site. The error has to do with this line of coding here: jQuery(function($){ $('.navbar a, .scroll a, .smoothscroll a').bind('click',function(event){ var $anchor = $(this); $('html, body').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 850,'easeInOutExpo'); event.preventDefault(); }); }); And the error I am getting is this: "SCRIPT5007: Unable to get value of the property 'top': object is null or undefined custom.min.js, line 6 character 197" The exact code it is highlighting is this part of the above code: $('html, body').stop().animate({ scrollTop: $($anchor.attr('href')).offset().top }, 850,'easeInOutExpo') All I know is that when I remove the above code, my scroll-to links stop working on pages such as these: http://www.northtownsremodeling.com/things-to-know.php You can see the popup error happen and stay in the console easily by going to a page with a filter like this: http://www.northtownsremodeling.com/bathroom/ And clicking one of the filter buttons. Ultimately, I am trying to make it so my scroll-to setting still works, but not have that error come up anymore. I made this script a long time ago, and I'm really confused as to what could be causing this error when everything is functioning perfectly otherwise? Thanks!

  • What's the best way to display a blown-up image using minimal JQuery?

    - by TkTech
    The Goal: On mouseover (or :hover), enlarge the preview image by about 400% and display it in the center of the page Remove the preview when the mouse leaves The Problem: Solutions like FancyBox are too bloated in FancyBox's case it ignores width and height for image elements, which makes it useless Most of these "lightboxes" steal focus when they're called Really, I'm just looking for a simple, efficient solution. Oops - StackOverflow won't let me post images yet, mockup - http://img685.imageshack.us/img685/7649/idae.png

  • Embedding script with timeout in case server goes down

    - by vsync
    I need a way to make sure my script won't block the viewed page, if the server serving the script is down (port 80 is blocked for some reason). Currently when I test it and take down the server (Apache), or close the firewall, I see in the browser that it is trying to load the resource (script in that case), without success for long seconds, until it aborts. Is there a nice way to get past this issue?
