  • Force an array to recalcuate length after sort

    - by Rhyono
    If you take an array and do the following: arr = []; arr[100] = 1; The length will be 101, which makes sense due to 0-99 being set as undefined Now if we sort that array: arr.sort() it will look like this: [1, undefined x100] since keys are not preserved. However, the length is still 101, since the undefined have all been moved to the end, instead of removed. Is this behavior intentional and if so: is there a built-in function that removes undefined and recalculates and why is it intentional? I am not asking how to write my own function to recalculate length. A sorted array's length can easily be forced with for (x = 0; arr[x] != undefined; x++);arr.length = x;

  • How to determine which element(s) are visible in an overflowed <div>

    - by jjross
    Basically, I'm trying to implement a system that behaves similar to the reading pane that's built into the Google Reader interface. If you haven't seen it, Google Reader presents each article in a separate box and as you scroll it highlights the current box (and marks the article as read). In addition to this, you can move forward or backward in the article list by clicking the previous and next buttons in the UI. I've basically figured out how to do most of the functionality. However, I'm not sure how I can determine which of my divs is currently visible in in the scrollable pane. I have a div that is set to overflow:auto. Inside of this div, there are other divs, each one containing a piece of content. I've used the following jquery plugin to make everything scroll based on a click of the "next" or "previous" button and it works like a charm: http://demos.flesler.com/jquery/serialScroll/ But I can't tell which div has "focus" in the scrollable pane. I'd like to be able to do this for two reasons. I'd like to highlight the item that the user is currently reading (similar to Google Reader). I need to do this regardless of whether or not they used the plugin to get there or used the browser's scroll bar. I need to be able to tell the plugin which item has focus so that my call to scroll to the "next" pane actually uses the currently viewed pane (and not just the previous pane that the plugin scrolled from). I've tried doing some searching but I can't seem to figure out a way to do this. I found lots of ways to scroll to a particular item, but I can't find a way to determine which element is visible in an overflowed div. If I can determine which items are visible, I can (probably) figure out the rest. I'm using jquery if that helps. Thanks!

  • 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.

  • Is canvas security model ignoring access-control-allow-origin headers?

    - by luklatlug
    It seems that even if you set the access-control-allow-origin header to allow access from mydomain.org to an image hosted on domain example.org, the canvas' origin-clean flag gets set to false, and trying to manipulate that image's pixel data will trigger a security exception. Shouldn't canvas' obey the access-control-allow-origin header and allow access to image's data without throwing an exception?

  • Prototype setStyle not working in IE6.

    - by Smickie
    Hi, I'm using prototype and setStyle in IE6 is just messing everything up. It's throwing a big error. I've Googled it but cant find a solution. I've identified the line in prototype with the IE script debugger, it's the final else block: setStyle: function(element, styles) { element = $(element); var elementStyle = element.style, match; if (Object.isString(styles)) { element.style.cssText += ';' + styles; return styles.include('opacity') ? element.setOpacity(styles.match(/opacity:\s*(\d?\.?\d*)/)[1]) : element; } for (var property in styles) if (property == 'opacity') element.setOpacity(styles[property]); else elementStyle[(property == 'float' || property == 'cssFloat') ? (Object.isUndefined(elementStyle.styleFloat) ? 'cssFloat' : 'styleFloat') : property] = styles[property]; return element; }, Anyone had this problem? P.S. normally I would use jQuery however this is someone else code I've had to update.

  • Is this the best way to query an element and its children?

    - by Soviut
    I'm trying to query an element and its children to find ID's that begin with a particular string. var foundIDs = containerElement.find('[id^=something]').andSelf().filter('id^=something'); The find() method only searches descendants so I thought I'd try andSelf(). However, andSelf() does not take a selector. This means that the container element is included regardless of whether it matches the find query or not and I then have to perform a secondary filter() on it to remove the container element if it didn't match after all. I attempted to put andSelf() before the find() but it didn't seem to pick up the container element into the stack. containerElement.andSelf().find('[id^=something]'); Is there any better way to achieve what I'm doing?

  • 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

  • JQuery .get() only passing first two data parameters in url

    - by The.Anti.9
    I have a $.get() call to a PHP page that takes 4 GET parameters. For some reason, despite giving the $.get() call all 4, it only passes the first two. When I look at the dev console in chrome, it shows the URL that gets called, and it only passes action and dbname. Heres the code: $.get('util/util.php', { action: 'start', dbname: db, url: starturl, crawldepth: depth }, function(data) { if (data == 'true') { status = 1; $('#0').append(starturl + "<ul></ul>"); $('#gobutton').hide(); $('#loading').show("slow"); while(status == 1) { setTimeout("update()",10000); } } else { show_error("Form data incomplete!"); } }); and heres the URL that I see in the developer console: http://localhost/pci/util/util.php?action=start&dbname=1hkxorr9ve1kuap2.db

  • jquery next siblings

    - by Contra
    Hi stackoverflow! (first post!) Ive been trying to get this problem solved, but I cant seem to figure it out without some serious workarounds. if I have the following html code: <ul> <li class="parent"> headertext </li> <li> text </li> <li> text </li> <li> text </li> <li class="parent"> headertext </li> <li> text </li> <li> text </li> </ul> Now, how do I now just select the li's following the first parent (or second, for that matter)? Basically selecting an li with class=parent and the following siblings until it reaches another li with the parent class. I could restructure the list with nested lists, but I dont want to do that. Any suggestions?

  • How to return function in document ready?

    - by FatDogMark
    I don't know if it is possible to do this, like I have 2 js files. The first Js File: var news_pos, about_pos, services_pos, clients_pos; function define_pos(){ var $top_slides=$('#top_slides'), $mid_nav=$('#mid_nav'), $news_section=$('#section-1'); var fixed_height = $top_slides.height()+$mid_nav.height(); news_pos = fixed_height-20 ; about_pos = fixed_height+$news_section.height(); services_pos = fixed_height+$news_section.height()*2; clients_pos = fixed_height+$news_section.height()*3; } $(document).ready(function(){ var section_news = $('#section-1'), section_about = $('#section-2'), section_services = $('#section-3'), section_clients = $('#section-4'); setheight(); function setheight(){ var section_height=$(window).height()+200; $section_news.height(section_height); $section_about.height(section_height); $section_services.height(section_height); $section_clients.height(section_height); define_pos(); } }); The second JS File: $(document).ready(function(){ var nav = { '$btn1':$('#btn1'), '$btn2':$('#btn2'), '$btn3':$('#btn3'), '$btn4':$('#btn4'), '$btn5':$('#btn5'), myclick : function(){ myclicked(nav.$btn1,0); myclicked(nav.$btn2,news_pos); myclicked(nav.$btn3,about_pos); myclicked(nav.$btn4,services_pos); myclicked(nav.$btn5,clients_pos); function myclicked(j,k){ j.click(function(e) { e.preventDefault(); $('html,body').animate({scrollTop: k}, 1000); }); } //Is it right to do return{'myclick':myclick}, how to call? seems not logical } } nav.myclick(); // Here will not work because it say news_pos is undefined //if I use setTimeout(nav.myclick,1000), it will works but I want to run it right the when position is caculated. }); How do I pass the nav.myclick() function to the frist js file and put it in setheight() and under define_pos()? By the way writing codes right in stackoverflow is strange,press tab not really give you any spacing.

  • Slide Effect happening too many times

    - by Abs
    Hello all, I call this functions on onmouseover and onmouseout for several divs. //Takes effect on divs with id, 62,63,64,65... function slide_it(id){ $('#options_'+id).slideToggle('slow'); } The problem is that if I move my mouse over and then mouse out, then again, mouse over and then mouse out. If I do this several times, the slide effect happens the same number of times I moved my mouse over and out of the div, as expected. But I can't figure out how I can do this once? I can set a variable, but I have several divs that this function is used by and I can't think of a simple way of doing this rather than storing things into an array, but this is messy! I really appreciate any help on this that is simple to implement! Thanks all for any help
