  • jQuery validation plugin: valid() does not work with remote validation ?

    - by a-dilla
    I got started by following this awesome tutorial, but wanted to do the validation on on keyup and place my errors somewhere else. The remote validation shows its own error message at the appropriate times, making me think I had it working. But if I ask specifically if a field with remote validation is valid, it says no, actually, its not. In application.js I have this... $("#new_user").validate({ rules: { "user[login]": {required: true, minlength: 3, remote: "/live_validations/check_login"}, }, messages: { "user[login]": {required: " ", minlength: " ", remote: " "}, } }); $("#user_login").keyup(function(){ if($(this).valid()){ $(this).siblings(".feedback").html("0"); }else{ $(this).siblings(".feedback").html("1"); } }) And then this in the rails app... def check_login @user = User.find_by_login(params[:user][:login]) respond_to do |format| format.json { render :json => @user ? "false" : "true" } end end I think that my problem might have everything to do with this ticket over at jQuery, and tried to implement that code, but, being new to jQuery, it's all a bit over my head. When I say bit, I mean way way. Any ideas to fix it, or a new way to look at it, would be a big help.

  • Can't Prevent Nested Div's from Overflowing when using Percent Sizes and Padding in CSS?

    - by viatropos
    I want to be able to layout nested divs with these properties: width: 100% height: 100% padding: 10px I want it to be such that, the children are 100% width and height of the remaining space after padding is calculated, not before. Otherwise, when I have a document like the below example, the child makes the scrollbars appear. But the scrollbars are not the main issue, the fact that the child stretches beyond the width of the parent container is. I can use all position: absolute declarations, but that doesn't seem right. Here is the code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="X-UA-Compatible" content="IE=7"> <title>Liquid Layout</title> <style> body, html { width:100%; height:100%; margin:0; padding:0; background-color:black; } #container { position:relative; width:100%; height:100%; background-color:red; opacity:0.7; } #child1 { position:relative; width:100%; height:100%; padding:10px; background-color:blue; } #nested1 { position:relative; background-color: white; width:100%; height:100%; } </style> </head> <body> <div id="container"> <div id="child1"> <div id="nested1"></div> </div> </div> </body> </html> How do I make it so, using position:relative or position:static, and percent sizes, the percents size the children according to the parent's width/height minus padding and margins? Do I have to resort to position:absolute and left/right/top/bottom? Thanks for the help, Lance

  • Monitor resolution changes look of website

    - by Andrew
    I have a website that looks fine in my resolution and even in the more common 1024 x 768. Yet, in someone else's browser in 1024 x 768, it's too wide and the website doesn't even center correctly. Is there a way to have a proper width layout that doesn't change when the resolution is changed?

  • Change stack order in mobile view at 1140 grid?

    - by iHaveacomputer
    I want to implement the 1140grid at my site. The layout is pretty simple: 100% header 25% sidebar 75% page 100% footer see also http://jsfiddle.net/KB5Nq/ the problem is that i would like to change the stack order when the site is in mobile view: 100% header 100% page 100% sidebar 100% footer however, by default it arranges the blocks in the same order as they appear in the source code: header, sidebar, page, footer. is there an easy css-only fix for that?

  • Understanding and Implementing a Force based graph layout algorithm

    - by zcourts
    I'm trying to implement a force base graph layout algorithm, based on http://en.wikipedia.org/wiki/Force-based_algorithms_(graph_drawing) My first attempt didn't work so I looked at http://blog.ivank.net/force-based-graph-drawing-in-javascript.html and https://github.com/dhotson/springy I changed my implementation based on what I thought I understood from those two but I haven't managed to get it right and I'm hoping someone can help? JavaScript isn't my strong point so be gentle... If you're wondering why write my own. In reality I have no real reason to write my own I'm just trying to understand how the algorithm is implemented. Especially in my first link, that demo is brilliant. This is what I've come up with //support function.bind - https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/bind#Compatibility if (!Function.prototype.bind) { Function.prototype.bind = function (oThis) { if (typeof this !== "function") { // closest thing possible to the ECMAScript 5 internal IsCallable function throw new TypeError("Function.prototype.bind - what is trying to be bound is not callable"); } var aArgs = Array.prototype.slice.call(arguments, 1), fToBind = this, fNOP = function () {}, fBound = function () { return fToBind.apply(this instanceof fNOP ? this : oThis || window, aArgs.concat(Array.prototype.slice.call(arguments))); }; fNOP.prototype = this.prototype; fBound.prototype = new fNOP(); return fBound; }; } (function() { var lastTime = 0; var vendors = ['ms', 'moz', 'webkit', 'o']; for(var x = 0; x < vendors.length && !window.requestAnimationFrame; ++x) { window.requestAnimationFrame = window[vendors[x]+'RequestAnimationFrame']; window.cancelAnimationFrame = window[vendors[x]+'CancelAnimationFrame'] || window[vendors[x]+'CancelRequestAnimationFrame']; } if (!window.requestAnimationFrame) window.requestAnimationFrame = function(callback, element) { var currTime = new Date().getTime(); var timeToCall = Math.max(0, 16 - (currTime - lastTime)); var id = window.setTimeout(function() { callback(currTime + timeToCall); }, timeToCall); lastTime = currTime + timeToCall; return id; }; if (!window.cancelAnimationFrame) window.cancelAnimationFrame = function(id) { clearTimeout(id); }; }()); function Graph(o){ this.options=o; this.vertices={}; this.edges={};//form {vertexID:{edgeID:edge}} } /** *Adds an edge to the graph.

  • CSS layout problem on Firefox with filling space between end of left column and footer

    - by Jean
    Basically, the left column is supposed to extend to the footer with the continuous red color. However, in Firefox on pages with lots of text, the column does not extend to the footer and leaves a large white gap--see site: http://library.luhs.org/JHSII/about.html I've tried readjusting the heights, creating the sticky footer, and other things I've read about on this site. So I admit that I'm stumped, and what's really odd is that the layout seems to work in IE as there is no white space! I didn't create the site, but I recently inherited it and trying to work through the mess Any help is much appreciated, here's the CSS #html,body{ margin:0; padding:0; border:0; height:100%; } #body{ background:#ffffff; min-width:965px; text-align:center; width: 600px; font: Geneva, Arial, Helvetica, sans-serif; } #.style7{ clear:both; height:1px; overflow:hidden; line-height:1%; font-size:0px; margin-bottom:-1px; } #fullheightcontainer{ margin-left:auto; margin-right:auto; text-align:left; position:relative; width:965px; height:100%; } #wrapper{ min-height:100%; height:100%; background:#660000; background-color: #660000; background-repeat: repeat; } #wrapp\65 r{ height:auto; } # html wrapper{ height:100%; } #outer{ z-index:1; position:relative; margin-left:150px; width:815px; background:#FFFFFF; height:100%; background-color: #FFFFFF; } #left{ width:151px; float:left; display:inline; position:relative; margin-left:-150px; } padding: 20px; border: 0; margin: 0 0 0 240px *>html #left{width:150px;} #container-left{ width:150px; color: #CCCCCC; } * html #left{margin-right:-3px;} #center{ width:800px; float:right; display:inline; margin-left:-1px; } #clearheadercenter{ height:125px; overflow:hidden; } #clearfootercenter{ height:50px; overflow:hidden; } #footer{ z-index:1; position:relative; clear: both; width:965px; height:50px; overflow:hidden; margin-top:-50px; background-color: #660000; } #subfooter1{ background:#FFFFCC; text-align:left; margin-left:150px; height:50px; } #header{ z-index:1; position:absolute; top:0px; width:815px; margin-left:150px; height:100px; overflow:hidden; background-color: #660000; } #subheader1{ background:#FFFFCC; text-align:center; height:70px; } #gfx_bg_middle{ top:0px; position:absolute; height:100%; overflow:hidden; width:815px; margin-left:150px; background:#FFFFFF; } # html #gfx_bg_middle{ display:none; } #floatingnav { margin: 5px 10px 5px 5px; padding: 0px 5px 5px; float: right; font: .75em/1.35em Geneva, Arial, Helvetica, sans-serif; height: 600px; width: 300px; } #floatingnav a { color: #630; } #floatingnav ul { margin-top: -5; } #.floatright { float: right; margin: 0 0 10px 10px; border: 1px solid #666; padding: 2px; } #outer{ word-wrap:break-word; } #table.s1 { border-width: medium; border-spacing: 2px; border-style: none; border-color: rgb(85, 0, 0); border-collapse: collapse; background-color: white; } #table.s1 th { border-width: medium; padding: 2px; border-style: groove; border-color: red; background-color: white; -moz-border-radius: 0px 0px 0px 0px; } #table.s1 td { border-width: medium; padding: 2px; border-style: groove; border-color: #660000; background-color: #FFFFFF; -moz-border-radius: 0px 0px 0px 0px; } #a:link { color: #000066; } #a:visited { color: #000066; } #p.sample { font-family: serif; font-style: normal; font-variant: normal; font-weight: normal; font-size: medium; line-height: 100%; word-spacing: normal; letter-spacing: normal; text-decoration: none; text-transform: none; text-align: left; text-indent: 0ex; }

  • Using jquery validate with multiple fields of the same name

    - by Matt H
    I am trying to get jquery validate to work on multiple fields. Reason being I have dynamically generated fields added and they are simply a list of numbers. So I thought I'd put together a basic example and followed the concept from the accepted answer in the following link: http://stackoverflow.com/questions/931687/using-jquery-validate-plugin-to-validate-multiple-form-fields-with-identical-name However, it's not doing anything useful. Why is it not working? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <script src="http://code.jquery.com/jquery-latest.js"></script> <script type="text/javascript" src="http://dev.jquery.com/view/trunk/plugins/validate/lib/jquery.delegate.js"></script> <script type="text/javascript" src="http://dev.jquery.com/view/trunk/plugins/validate/jquery.validate.js"></script> <script> $("#submit").click(function(){ $("field").each(function(){ $(this).rules("add", { required: true, email: true, messages: { required: "Specify a valid email" } }); }) }); $(document).ready(function(){ $("#myform").validate(); }); </script> </head> <body> <form id="myform"> <label for="field">Required, email: </label> <input class="left" id="field" name="field" /> <input class="left" id="field" name="field" /> <input class="left" id="field" name="field" /> <input class="left" id="field" name="field" /> <br/> <input type="submit" value="Validate!" id="submit" name="submit" /> </form> </body> </html>

  • jQuery 1.4 Dynamically created images aspect ratio incorrect in IE8 and max-width

    - by Chris
    After upgrading to jQuery 1.4, when I try to add an image to a page dynamically using jQuery 1.4 in IE8, the image will lose the correct aspect ratio. This appears to affect only IE8 (IE7 and Firefox work fine) with jQuery 1.4 (1.3.2 works fine). Including the jQuery compatability file does not fix the problem. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js" language="javascript" type="text/javascript"></script> <!-- Switching to 1.3.2 fixes the problem --> <!--<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js" language="javascript" type="text/javascript"></script>--> <script type="text/javascript"> $(document).ready(function() { var dynImg = $('<img></img>').attr('src', 'http://www.google.com/intl/en_ALL/images/logo.gif'); $('body').append(dynImg); }); </script> <style type="text/css"> img { max-width: 5em; } </style> </head> <body></body></html>

  • jQuery and XHTML layout problems in ie7

    - by abysslogic
    Hi there, I am back again with more layout problems on my up and coming website. I am able to achieve the proper animation, positioning and results with my layout / splash on every modern browser (excluding ie7 or older). I have an image in the center of the page, that is text-align: center'd, and pushed to a vertical center by having a div (#SPLASH_HEAD) set to 50% on the top half of the page. The loading animation changes the height of #SPLASH_HEAD to 0px, to drag the image to the top (and then do other things). In ie7 (or compatability mode), it appears that there is an error in jquery-1.4.2.min.js, line 116 char 165 (which I dont think has anything to do with the actual jQuery file itself). The splash is not centered either vertically (#SPLASH_HEAD does not register at 50% of window height) and is not centered properly with margin-left. Also, none of the other elements are hidden properly (with .hide()) as ie7 does not appear to be loading all of my jQuery / javascript. heres a link: www.voidsync.com/test (it would be easier to view the source on there) thanks!

  • jQuery .load() and sub-pages

    - by user354051
    Hi, I am not just a newbie with Javascript. I am developing a simple site to get my hands on web programming. The web site is simple and structure is like this: A simple ul/li/css based navigation menu Sub pages are loaded in "div" using jQuery, when ever user click appropriate menu item. Some of the sub-pages are using different jQuery based plugins such as LightWindow, jTip etc. The jQuery function that loads the sub-page is like this: function loadContent(htmlfile){ jQuery("#content").load(htmlfile); }; The menu items fires loadContent method like this: <li><a href="javascript:void(0)" onclick="loadContent('overview.html');return false">overview</a></li> This loads a sub-page name "overview.html" inside the "div". That's it. Now this is working fine but some of the sub-pages using jQuery based plugins are not working well when loaded inside the "div". If you load them individually in the browser they are working fine. Based on above I have few qustions: Most of the plugins are based on jQuery and sub-pages are loaded inside the "index.html" using "loadContent" function. Do I have to call <script type="text/javascript" src="js/jquery-1.4.2.min.js"></script> on each and every sub-page? If a page is using a custom jQuery plugin, then where do I call it? In "index.html" or on the page where I am using it? I think what ever script you will call in "index.html", you don't to have call them again in any of the sub pages you are using. Am I right here? Thanks Prashant

  • jQuery problem with change event and IE8

    - by Marcus
    There is a bug in jQuery 1.4.2 that makes change event on select-element getting fired twice when using both DOM-event and a jQuery event, and this only on IE7/8. Here is the test code: <html> <head> <script src="http://code.jquery.com/jquery-1.4.2.js" type="text/javascript"></script> <script type="text/javascript"> jQuery(document).ready(function() { jQuery(".myDropDown").change(function() { }); }); </script> </head> <body> <select class="myDropDown" onchange="alert('hello');"> <option>1</option> <option>2</option> <option>3</option> <option>4</option> </select> </body> </html> Ticket to actual bug: http://dev.jquery.com/ticket/6593 This causes alot of trouble for us in our application cause we use both ASP.NET-events mixed with jQuery and once you hook up a change event on any element every select (dropdown) gets this double firing problem. Is there anyone who knows a way around this in the meantime until this issue is fixed?

  • error handler isn't called when file is uploaded via ajax using jQuery form plugin

    - by scompt.com
    Here's my test case. If the form is posted, a 500 error response is sent. If not, the form is sent. If the file input tag is commented out, the error handler is called. If the file input tag is present, the error handler isn't called. I think this might have something to do with the fact that jQuery needs to use an iframe to handle the upload and iframes don't seem to respond to the error handler. Edit: If I add iframe: true to the options passed to ajaxSubmit to force the use of an iframe, the non-file-upload case stops working also, so it definitely has to do with the iframe. Edit2: I'm using the jQuery Form Plugin. <?php if($_SERVER['REQUEST_METHOD'] == 'POST') { header('HTTP/1.1 500 Internal Server Error'); die; } else {?> <html><head> <script type='text/javascript' src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js?ver=2.9.2'></script> <script type='text/javascript' src='http://github.com/malsup/form/raw/master/jquery.form.js?v2.43'></script> <script type="text/javascript"> jQuery(document).ready(function() { jQuery('a').click(function() {jQuery('form').ajaxSubmit({error: function(){alert('error handler called');}})}); }); </script> </head><body> <form method="POST"> <input type="text" name="mytext" /> <input type="file" name="myfile" /><!-- comment this element out --> <input type="hidden" name="blah" value="blah" /> <a>submit</a> </form> </body></html> <?php } Is there any way to get the error handler to be called in both situations?

  • Which is the best jQuery-powered site?

    - by Reigel
    This "Top 10 JavaScript (jQuery) Powered Sites", posted about 2 years ago, was the one that invites me(after seeing the list) to use jQuery. All the sites in that list made me realize how cool it is to build sites powered by jQuery. And now more and more sites are being powered by jQuery. More and more developers are learning jQuery. Two years have past now but I still do a search to google for best sites and still got me to that link and which the link is not updated from the first time I have looked at it. Here at stackoverflow, there are lots of jQuery user. I was thinking if we can here show some of the sites that you know that is powered by jQuery which you think is best. If you can, please make it one site one answer, so that we can make a vote if it's really best jQuery powered site. We will take a look if it is really well implemented ( the way the codes are written, fast speed site, etc...) and deserves to be the best. Lot's of viewers will benefit from it. Like, we can view and have an idea of how we will make our next project cooler, faster, and powerful.

In essence, the user comes to the page, and their location is found using the HTML5 method and then using jQuery, the location is posted to a page which saves the location/address to a codeigniter session, but if they want to update their location, or change to a different location(IE they want to use their work address as the location instead of their present address), theres a jQuery colorbox that displays and lets them type in a custom address. Everything works flawlessly to get the initial location, but when I try and get the updated location saved, I receive the error "Uncaught TypeError: Object [object DOMWindow] has no method 'lat'" which then Google Chrome references as being an error not in jQuery, but in the file for Google Maps API. Any suggestions? jQuery('.inputsubmit').click(function() { //Takes values from user submitted fields and parses them into an address string var street = jQuery('.inputaddress').val(); var city = jQuery('.inputcity').val(); var state = jQuery('.inputstate').val(); var address = street +" "+ city +", " +state; geocoder = new google.maps.Geocoder(); var geocoderresult= geocoder.geocode({'address': address}, function(results, status) { if (status == google.maps.GeocoderStatus.OK) { var newlocation = results[0].geometry.location; //Posts coordinates and address string to a CodeIgniter function to update users session information jQuery.post("somepage", {location: newlocation, address: address},function(data) { alert("Data Loaded: " + data); }); } else { alert("Geocoder failed due to: " + status); } }); }); I've tried everything I can think of to get the post to work. All of the code works up till the point, and I've commented out the post line and everything works correctly. This is one of our main website's features, to provide instant and quick results based off of location. Thanks!

  • jQuery update not replacing js files in Drupal 6.16.

    - by vr3690
    Hi, I am using jquery update in drupal 6.16 along with a lot of other modules. I am trying to use jquery ui 1.7.2 to render tabs. But unfortunately they don't work properly since jquery update is not replacing the jquery file (jquery 1.3.2). I checked the version using $.fn.jquery (in firebug) and got 1.2.6 (not 1.3.2 as required) as the result - and as expected the aggregated js file was using the 1.2.6 version of jquery (see source). earlier I had just replaced the core script files in /misc with the js files in sites/default/modules/jquery_update/replace folder (like you'd do in 5.x) and got the necessary result (i also renamed jquery.min.js to jquery.js ). now suddenly that stopped working after i upgraded to 6.x-2.0-alpha1 and also installed the mollom module. disabling/uninstalling mollom or down-grading jQuery update does not seem to help. the problem only occurs on the front page though. other content pages have jQuery 1.3.2 the problem can be seen here. So, basically, for some reason, jquery update is not replacing the jquery files (as it is supposed to) on the front page. and i cannot figure out why that happens. any ideas?

  • Same jQuery code returns two different results – Submit Button Text

    - by Lijo
    I have two jQuery codes - http://jsfiddle.net/Lijo/CXGX7/7/ and http://jsfiddle.net/Lijo/CXGX7/8/ . The first code returns undefined whereas the second code returns text of button.

  • Jquery Sorting by Letter

    - by Batfan
    I am using jquery to sort through a group of paragraph tags (kudos to Aaron Harun). It pulls the value "letter" (a letter) from the url string and displays only paragraphs that start with that letter. It hides all others and also consolidates the list so that there are no duplicates showing. See the code: var letter = '<?php echo(strlen($_GET['letter']) == 1) ? $_GET['letter'] : ''; ?>' function finish(){ var found_first = []; jQuery('p').each(function(){ if(jQuery(this).text().substr(0,1).toUpperCase() == letter){ if(found_first[jQuery(this).text()] != true){ jQuery(this).addClass('current-series'); found_first[jQuery(this).text()] = true; }else{ jQuery(this).hide(); } } else{ jQuery(this).hide();} }) } Been working with this all day and I have 2 Questions on this: Is there a way to get it to ignore the word 'The', if it's first? For example, if a paragraph starts with 'The Amazing', I would like it to show up on the 'A' page, not the 'T' page, like it currently is. Is there a way to have a single page for (all) numbers? For example, the url to the page would be something similar to domain.com/index.php?letter=0 and this would show only the paragraph tags that start with a number, any number. I can currently do this with single numbers but, I would like 1 page for all numbers.

  • jquery touch punch - draggable on ipad

    - by dshuta
    i am starting to work with the jquery touch punch extensions in order to allow draggability on ipad, but i am getting tripped up right away. probably something terribly dumb on my part. the draggable example from the developer works fine on my ipad: http://furf.com/exp/touch-punch/draggable.html but not for me: http://danshuta.com/touchpunch/ this works fine in my desktop browser, but on the ipad it just focuses on the block and scrolls the entire page as i drag, as if it were just an image or other normal embedded object. as this is what happens normally with jquery/ui on ipad, this makes me think it is not loading or otherwise ignoring the "punch" code from my site (though if i host the jquery files on my site via the same path, those load and function fine in desktop browser). here's the entire code, very basic: <!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8" /> <title>Touchpunchtest</title> <script src="http://code.jquery.com/jquery.min.js"></script> <script src="http://code.jquery.com/ui/1.8.17/jquery-ui.min.js"></script> <script src="js/jquery.ui.touch-punch.js"></script> </head> <body> <div id="draggybox" onclick="void(0)" style="width: 150px; height: 150px; background: green;"></div> <script>$('#draggybox').draggable();</script> </body> </html> what am i missing?!

  • Advise guidance on how to form this jQuery script for show/hide fade element

    - by Rick
    Hey guys.. I basically have several links on the left side of the screen and on the right is a preview window. Below the preview window is another box for the affiliate link code. So what I am trying to do is create an affiliate page where you choose the banner size on the left by clicking on the link and on the right you see it dynamically change to the banner size and the code changes accordingly as well. So far I have the following code and it works but it seems very very cumbersome and bloated. Can you see if I can trim this down? jQuery(".banner-style li").click(function() { jQuery(".banner-style li").removeClass("selected"); jQuery(this).addClass("selected"); var $banner = jQuery(this).attr("class"); $banner = $banner.replace(" selected",""); jQuery(".preview img").fadeOut('fast',function() { jQuery(".preview img").attr("src", "http://localhost/site/banners/"+$banner+".jpg") .fadeIn('slow'); }); jQuery(".code p").removeClass('hide').hide(); jQuery(".code p."+$banner).show(); }); Also to note the funny thing is in FF, when you click for the first to on any link, the original image on the right fades out and in real quick and then it loads the "clicked" image. This does not happen in other browsers...

  • Keep the current Jquery accordion pane open after asp.net postback?

    - by Xaisoft
    I have a jquery accordion on an asp.net aspx weppage. Inside the panes, I have asp.net buttons. When I click on the button, the pane I was in, closes and reloads the page, defaulting to the first pane. I don't mind the reload, but is there a way to keep the current pane open after the reload. Right now, I am just calling accordion() on a div with the id of accordion.

  • Anyone have ideas for solving the "n items remaining" problem on Internet Explorer?

    - by CMPalmer
    In my ASP.Net app, which is javascript and jQuery heavy, but also uses master pages and .Net Ajax pieces, I am consistently seeing on the status bar of IE 6 (and occasionally IE 7) the message "2 items remaining" or "15 items remaining" followed by "loading somegraphicsfile.png|gif ." This message never goes away and may or may not prevent some page functionality from running (it certainly seems to bog down, but I'm not positive). I can cause this to happen 99% of the time by just refreshing an .aspx age, but the number of items and, sometimes, the file it mentions varies. Usually it is 2, 3, 12, 13, or 15. I've Googled for answers and there are several suggestions or explanations. Some of them haven't worked for us, and others aren't practical for us to implement or try. Here are some of the ideas/theories: IE isn't caching images right, so it repeatedly asks for the same image if the image is repeated on the page and the server assumes that it should be cached locally since it's already served it in that page context. IE displays the images correctly, but sits and waits for a server response that never comes. Typically the file it says it is waiting on is repeated on the page. The page is using PNG graphics with transparency. Indeed it is, but they are jQuery-UI Themeroller generated graphics which, according to the jQuery-UI folks, are IE safe. The jQuery-UI components are the only things using PNGs. All of our PNG references are in CSS, if that helps. I've changed some of the graphics from PNG to GIF, but it is just as likely to say it's waiting for somegraphicsfile.png as it is for somegraphicsfile.gif Images are being specified in CSS and/or JavaScript but are on things that aren't currently being displayed (display: none items for example). This may be true, but if it is, then I would think preloading images would work, but so far, adding a preloader doesn't do any good. IIS's caching policy is confusing the browser. If this is true, it is only Microsoft server SW having problems with Microsoft's browser (which doesn't surprise me at all). Unfortunately, I don't have much control over the IIS configuration that will be hosting the app. Has anyone seen this and found a way to combat it? Particularly on ASP.Net apps with jQuery and jQuery-UI? UPDATE One other data point: on at least one of the pages, just commenting out the jQuery-UI Datepicker component setup causes the problem to go away, but I don't think (or at least I'm not sure) if that fixes all of the pages. If it does "fix" them, I'll have to swap out plug-ins because that functionality needs to be there. There doesn't seem to be any open issues against jQuery-UI on IE6/7 currently... UPDATE 2 I checked the IIS settings and "enable content expiration" was not set on any of my folders. Unchecking that setting was a common suggestion for fixing this problem. I have another, simpler, page that I can consistently create the error on. I'm using the jQuery-UI 1.6rc6 file (although I've also tried jQuery-UI 1.7.1 with the same results). The problem only occurs when I refresh the page that contains the jQuery-UI Datepicker. If I comment out the Datepicker setup, the problem goes away. Here are a few things I notice when I do this: This page always says "(1 item remaining) Downloading picture http:///images/Calendar_scheduleHS.gif", but only when reloading. When I look at HTTP logging, I see that it requests that image from the server every time it is dynamically turned on, without regard to caching. All of the requests for that graphic are complete and return the graphic correctly. None are marked code 200 or 304 (indicating that the server is telling IE to use the cached version). Why it says waiting on that graphic when all of the requests have completed I have no idea. There is a single other graphic on the page (one of the UI PNG files) that has a code 304 (Not Modified). On another page where I managed to log HTTP traffic with "2 items remaining", two different graphic files (both UI PNGs) had a 304 as well (but neither was the one listed as "Downloading". This error is not innocuous - the page is not fully responsive. For example, if I click on one of the buttons which should execute a client-side action, the page refreshes. Going away from the page and coming back does not produce the error. I have moved the script and script references to the bottom of the content and this doesn't affect this problem. The script is still running in the $(document).ready() though (it's too hairy to divide out unless I absolutely have to). FINAL UPDATE AND ANSWER There were a lot of good answers and suggestions below, but none of them were exactly our problem. The closest one (and the one that led me to the solution) was the one about long running JavaScript, so I awarded the bounty there (I guess I could have answered it myself, but I'd rather reward info that leads to solutions). Here was our solution: We had multiple jQueryUI datepickers that were created on the $(document).ready event in script included from the ASP.Net master page. On this client page, a local script's $(document).ready event had script that destroyed the datepickers under certain conditions. We had to use "destroy" because the previous version of datepicker had a problem with "disable". When we upgraded to the latest version of jQuery UI (1.7.1) and replaced the "destroy"s with "disable"s for the datepickers, the problem went away (or mostly went away - if you do things too fast while the page is loading, it is still possible to get the "n items remaining" status). My theory as to what was happening goes like this: The page content loads and has 12 or so text boxes with the datepicker class. The master page script creates datepickers on those text boxes. IE queues up requests for each calendar graphic independently because IE doesn't know how to properly cache dynamic image requests. Before the requests get processed, the client area script destroys those datepickers so the graphics are no longer needed. IE is left with some number of orphaned requests that it doesn't know what to do with.

  • jQuery onkeyup event in textarea that does not fires when nothing change.

    - by Kucebe
    I was thinking to a function that check the key value pressed, and accept only the most common characters, canc, enter, ... because i need it only for basic ascii character set (not ñ, c, chinese chars, ...). Or function that after every keyup checks if value has changed. But really jQuery doesn't have an event handler for this situation? Oh, it should be cross-borwser.

  • Cascading dropdownlist jQuery does not retain value on post back.

    - by John Smith
    I have two html select server control on an add data form page. the user selects a value in the first html select server control and then values are populated into the second html select server control with jquery. The problem is when a a user clicks the save button and the page posts back, the values are no longer in the drop down list populated by jQuery. The drop downlist is a html server control, shouldn't it retain the values on post-back? How can I retain the values and save the selected value to the database? $(document).ready(function() { $("#<%=ddlCourseWare.ClientID %>").change(function() { var courseWareId = this.value; try { $.ajax({ type: "POST", url: "Left_SubCategory.aspx/GetTabData", data: "{courseWareId:" + courseWareId + "}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(data) { var result = json_parse(data.d); $("#<%=ddlTabType.ClientID %>")[0].innerHTML = ''; if (result.length > 0) { $.each(result, function(key, item) { $("#<%=ddlTabType.ClientID %>").append($("<option></option>").val(item.id).html(item.TabName)); }); } else { $("#<%=ddlTabType.ClientID %>").append($("<option></option>").val('0').html('--Select--')); } }, error: function(request, status, error) { alert(request.responseText); } }); } catch (ex) { alert(ex); } }); }); HTML <select id="ddlCourseWare" name="ddlCourseWare" runat="server" Width="230px" class="TextBox" Height="18px" > <select id="ddlTabType" name="ddlTabType" runat="server" Width="230px" class="TextBox" Height="18px" onchange="BindMainCat();"> <option>--Select--</option> </select> C# private void BindCourseWare() { ddlCourseWare.DataSource = courseWare.GetCourseWare(); ddlCourseWare.DataTextField = "CourseWareType"; ddlCourseWare.DataValueField = "id"; ddlCourseWare.DataBind(); ddlCourseWare.Items.Insert(0, "----Select Course Ware----"); } [WebMethod] public static string GetTabData(int courseWareId) { var result = new CourseWare().GetCourseTabByCoursewareId(courseWareId); JavaScriptSerializer json_tabs = new JavaScriptSerializer(); string jsonArray_tabs = json_tabs.Serialize(result); return jsonArray_tabs; } protected void btnSave_Click(object sender, EventArgs e) { int mainCategoryID1 = int.Parse(ddlTabType.Value); // not working int mainCategoryID2 = int.Parse(Request["ctl00$ContentPlaceHolder1$ddlTabType"]); // working but always return same value means the upper value (selected index 1) }
