  • What's wrong with this jQuery example?

    - by Sven Larson
    The following jQuery example should put some text into the div, but it doesn't. I tried Firefox, Google Chrome and Internet Explorer. <html> <head> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" language="javascript"></script> <script language="javascript"> $(window).load(function() { $('adiv').html('<p>hello world</p>'); alert('done'); }); </script> </head> <body> <div id="adiv"> </div> </body> </html> Sorry, this might be stupid, but I'm stuck.

  • Speeding up jQuery empty() or replaceWith() Functions When Dealing with Large DOM Elements

    - by Levi Hackwith
    Let me start off by apologizing for not giving a code snippet. The project I'm working on is proprietary and I'm afraid I can't show exactly what I'm working on. However, I'll do my best to be descriptive. Here's a breakdown of what goes on in my application: User clicks a button Server retrieves a list of images in the form of a data-table Each row in the table contains 8 data-cells that in turn each contain one hyperlink Each request by the user can contain up to 50 rows (I can change this number if need be) That means the table contains upwards of 800 individual DOM elements My analysis shows that jQuery("#dataTable").empty() and jQuery("#dataTable).replaceWith(tableCloneObject) take up 97% of my overall processing time and take on average 4 - 6 seconds to complete. I'm looking for a way to speed up either of the above mentioned jQuery functions when dealing with massive DOM elements that need to be removed / replaced. I hope my explanation helps.

  • Lightbox scrolling issue with IE7 & 8

    - by BlazeK
    The lightbox that i am using works great with all browsers except for IE. In IE, its giving me triple scrolls. http://obliqueinteractive.com/demo/monster/ CSS code for the iframe: #wrap { float:left; width:800px; height:500px; overflow-x: hidden; overflow-y: scroll; } #content-wrap { float:left; width:700px; padding-left:50px; } Why is IE adding additional scrolls to the lightbox window? any suggestions?

  • jQuery Validation 1.10 and MVC server-side errors

    - by sam360
    This feature used to work just fine on my website. If I added a custom error to ModelState, the input on the page would be marked as "input-validation-error" and the Html.ValidationMessage() would take care of rendering a span with the error message inside it. Due to incompatibility reasons we had to upgrade our jQuery Validation to 1.10: Now when I add a custom error to ModelState, I can debug and see that the HTML elements being rendered correctly, but as soon as the page load is completed, jQuery Validation removes the error message and set the "class" attribute of the input to "valid"! Has any one else come across this issue? UPDATE Testing further shows that the error message is shown on the screen until the field gains focus. As soon as the field gains focus jQuery Validation removes the customer server-side error message and marks the field as good.

  • problem with template: negative margins on float

    - by Fuxi
    hi, i'm having a very strange problem with the wordpress template. i'd like to place 2 divs besides each other like this: <div style='float:left;'> left div </div> <div style='float:right'> right div </div> normally this works as it should - both divs should stick directly to each other - but something in the style.css (which uses css reset) causes the right div to overlap the left div with ~ 5pixels. i searched the whole .css for it but couldn't find out :(( it's just a fact that it must be something with the default css. anyone knows what is causing this - some fix? thanks

  • nth-child doesn't respond to class

    - by Arne Stephensson
    Is it possible to get the nth-child pseudo-selector to work with a specific class? See this example: http://jsfiddle.net/fZGvH/ I want to have the second DIV.red turn red, but it doesn't apply the color as expected. Not only that, but when you specify this, it changes the 5th DIV to red: div.red:nth-child(6) When you specify this, it changes the 8th DIV to red: div.red:nth-child(9) It seems to be one DIV behind. There are only 8 DIV tags in the example so I don't know why nth-child(9) even works. Testing using Firefox 3.6, but in my actual production code the same problem occurs in Chrome. I'm not understanding something about how this is supposed to work, would appreciate clarification. Also, this will change the 6th DIV to red, but what I actually want is for it to change the second DIV.red to red: div.red:nth-of-type(6) And I don't understand why nth-child() and nth-of-type() respond differently, since there are only eight tags of the same type in the document.

  • Conversion of DOM element selection code to jQuery

    - by Tom McDonnell
    I have a large Javascript codebase to convert to jQuery. The code is structured such that DOM elements are created in Javascript (using a library called DomBuilder), and saved to variables if they will be needed later, before being added to the DOM. Eg. var inputs = { submitConfirm: INPUT({type: 'button', value: 'Submit'}), submitCancel : INPUT({type: 'button', value: 'Cancel'}) }; document.appendChild(inputs.submitConfirm); Then later for example... inputs.submitCancel.style.display = 'none'; inputs.submitCancel.addEventListener('click', onClickSubmitCancel, false); My problem is that jQuery seems to lack a way of manipulating DOM elements directly, as opposed to selecting them first (with for example $('#submitCancel'). Can anyone suggest a way to directly translate the last two Javascript lines given above to use jQuery, given that the DOM elements are already available, and so do not need to be selected?

  • How to force div to appear below not next to another?

    - by Vafello
    I would like to place my div below the list, but actually it is placed next to the list.The list is generated dynamically, so it doesn't have a fixed hight. I would like to have the map div on the right, and on the left (next to the map) the list placed on top and the second div below the list. #map { float:left; width:700px; height:500px; } #list { float:left; width:200px; background:#eee; list-style:none; padding:0; } #similar { float:left; width:200px; background:#000; } <div id="map"></div> <ul id="list"></ul> <div id ="similar"> this text should be below, not next to ul. </div> Any ideas?

  • Help porting a bit of Prototype JavaScript to jQuery

    - by ewall
    I have already implemented some AJAX pagination in my Rails app by using the example code for the will_paginate plugin--which is apparently using Prototype. But if I wanted to switch to using jQuery for future additions, I really don't want to have the Prototype stuff sitting around too (yes, I know it's possible). I haven't written a lick of JavaScript in years, let alone looked into Prototype and jQuery... so I could use some help converting this bit into jQuery-compatible syntax: document.observe("dom:loaded", function() { // the element in which we will observe all clicks and capture // ones originating from pagination links var container = $(document.body) if (container) { var img = new Image img.src = '/images/spinner.gif' function createSpinner() { return new Element('img', { src: img.src, 'class': 'spinner' }) } container.observe('click', function(e) { var el = e.element() if (el.match('.pagination a')) { el.up('.pagination').insert(createSpinner()) new Ajax.Request(el.href, { method: 'get' }) e.stop() } }) } }) Thanks in advance!

  • jQuery featured content slider

    - by azz0r
    Hello, I have a content area that loops through divs and shows there content. I'm having trouble making it display the initial content, unfortunately it waits 5000 milliseconds before triggering the very first content area to display. Anyone spot an easy way to make it display the initial area, then slide to the next area and do them at 5000 milliseconds.

  • Page loading effect with jquery

    - by Andy Simpson
    Hello all, Is there a way to use jquery (or other method) to display a loading div while page loads? I have a table that is populated using PHP/MySQL and can contain several thousand rows. This is then sorted using the tablesorter plugin for jquery. Everything works fine, however the page can sometimes take 4-5 seconds to fully load and it would be nice to display a 'loading...' message within a div which automatically disappears when whole table is loaded. I have heard of loadmask plugin for jquery - would this be suitable for my needs and if not any alternative? No AJAX calls are being made while loading this table if thats relevant. Thanks in advance Andy

  • Jquery CPU usage

    - by nharry
    I am using Jquery to make an image scroll across my page horizontally. The only problem is that it uses a serious amount of cpu usage. Up to 100% on a single core laptop in firefox. What could cause this??? Jquery <script> jQuery(document).ready(function() { $(".speech").animate({backgroundPosition: "-6000px 0px"}, 400000, null); }); </script> CSS .speech { /*position:fixed;*/ top:0; left:0px; height:400px; width:100%; z-index:-1; background:url(/images/speech.png) -300px -500px repeat-x; margin-right: auto; margin-left: auto; position: fixed; } HTML <div class="speech"></div>

  • How can I add styles to dynamically added table cells?

    - by Doc Hoffiday
    In my program I have a table that, when loaded, has jQuery add some styles/classes to the table cells and table headers. Everything works fine until rows are added via functionality on the rest of the page. Instead of adding the classes to the table cell during addition, is it possible to "listen" or fire some event that checks to see if child elements were added to the table. Essentially, I want something functionally equivalent to this: $("#table td").live("ready", function(){ // do something }); but the live/ready won't work on a table cell... Any ideas?

  • Official way to ask jQuery wait for all images to load before executing something

    - by Simon_Weaver
    In jQuery when you do this: $(function() { alert("DOM is loaded, but images not necessarily all loaded"); }); It waits for the DOM to load and executes your code. If all the images are not loaded then it still executes the code. This is obviously what we want if we're initializing any DOM stuff such as showing or hiding elements or attaching events. Let's say though that I want some animation and I don't want it running until all the images are loaded. Is there an official way in jQuery to do this? The best way I have is to use <body onload="finished()">, but I don't really want to do that unless I have to. Note: There is a bug in jQuery 1.3.1 in Internet Explorer which actually does wait for all images to load before executing code inside $function() { }. So if you're using that platform you'll get the behavior I'm looking for instead of the correct behavior described above.

  • PHP script for creating calendar table or jquery complete solution required

    - by finn_meister
    Ok so this is what I want to make: http://i44.tinypic.com/eiwphl.jpg red = booked green = available I have data in mysql in the format of: property_id, booked_from, booked_until . Before I start trying to create the correct loops etc to create and style the table, i thought i best ask if there are already good jquery plugins / php classes create this visual interface and uncluttered enough to allow me to add a select date range method (like Google Analytics)? I'm looking for something to create a basic calendar table on a loop, which i can then style and add jquery features. Though worth asking if there's a complete package that already does what i plan on making?!! (jquery ui's date-picker doesn't look powerful enough / easy enough to modify)

  • jQuery Optimizations

    - by aepheus
    I've just come to the end of a large development project. We were on a tight timeline, so a lot of optimization was "deferred". Now that we met our deadline, we're going back and trying to optimize things. My questions is this: What are some of the most important things you look for when optimizing jQuery web sites. Alternately I'd love to hear of sites/lists that have particularly good advise for optimizing jQuery. I've already read a few articles, http://www.tvidesign.co.uk/blog/improve-your-jquery-25-excellent-tips.aspx was an especially good read.
