  • Recommended lightweight jQuery lightbox plug-in?

    - by Mat Harden
    I need a lightbox plugin that is styled similar to FancyBox but will allow me to add text to the same white background as the image. Lightweight because I don't want many features as it's going to be added to an already heavy JS page. Preferably without Ajax features as I'll be handling this myself. Therefore I'm ruling out the use of Thickbox, Fancybox and jQuery UI. Basically I want the plugin to be a currently supported light-box jQuery plug-in that handles all the cross browser styling issues which I can then customise.

  • One-to-many Associations Empty Columns Issue (Ext on Rails)

    - by Joe
    I'm playing with rewriting part of a web application in Rails + Ext. However, I'm having trouble getting an associated models' name to display in the grid view. I've been able to successfully convert several models and arrange the views nicely using tabs and Ext's layout helpers. However, I'm in the middle of setting up an association -- I've followed along with Jon Barket's tutorial on how to do this using Ext -- and I've made all the Rails and JS changes suggested (with appropriate name changes for my models,) the result being that the combo box is now being correctly populated with the names of the associated models, and changes are actually written correctly to database, BUT the data doesn't show up in the column, it's just empty. However, the correct data is there in the 'detail' view. Really just wondering if anyone else ran into this, or had any thoughts on what could be happening. Definitely willing to post code if requested; just note that (AFAIK) my changes follow the tutorial pretty closely. Thanks in advance! UPDATE: Alright, slight progress - kind of. I can get the associated model id # displaying properly -- just by modifying the column model slightly. But I can't get the virtual attribute displayed in the main table (in Jon's example it's country_name.) It still goes blank when I change the data source for that column from dataIndex: 'model[associated_model_id]' to dataIndex: 'virtual_attributes[associated_model_name]' ANOTHER UPDATE: Bump. Has NOBODY here tried integrating Ext with Rails?

  • Setting CSS attributes on Change using jQuery

    - by Nick B
    I want to change css visibility and display attributes using jQuery on click when the state of another div's visibility attribute changes. (Many apologies for the obfuscated markup, but needing to manipulate someone else's construction): There are four instances of [data-label="Checkbox"] [data-label="Checked"] in this page. I want to set [data-label="trash"] and [data-label="Sort Options"] to visibility: visible; display: [empty value] when any of the [data-label="Checkbox"] [data-label="Checked"]'s attributes changes to 'visibility', 'visible'. Else, if none of [data-label="Checkbox"] [data-label="Checked"]'s have the attribute 'visibility', 'visible', I want to set [data-label="trash"] and [data-label="Sort Options"] back to their initial states: display: none; visibility: hidden;. Here's the markup: <div data-label="Sort Options" style="display: none; visibility: hidden;"> <div data-label="trash" style="display: none; visibility: hidden;"></div> </div> <div data-label="Checkbox"> <div data-label="Unchecked"></div> <div data-label="Checked" style="display: none; visibility: hidden;"></div> </div> Here is what I have tried unsuccessfully: $('[data-label="Checkbox"]').click(function() { if ('[data-label="Checkbox"] [data-label="Checked"]').css('visibility', 'visible') { $('[data-label="trash"], [data-label="Sort Options"]').css({'display': '', 'visibility': 'visible'}); } else { $('[data-label="trash"], [data-label="Sort Options"]').css({'display': 'none', 'visibility': 'hidden'}); } }); Any help would be greatly appreciated! Thanks

  • Google Chrome hardware acceleration making game run slow

    - by powerc9000
    So I have been working on a game in HTML5 canvas and noticed that the games lags and performs much slower when hardware acceleration is turned on in Google Chrome then when it is turned off. You can try for yourself here From doing some profiling I see that the problem lies in drawImage. More specifically drawing one canvas onto another. I do a lot of this. Hardware Acceleration on. Hardware Acceleration off. Is there something fundamental I am missing with one canvas to another? Why would the difference be that profound?

  • JQuery div tag has children in FireFox but not Chrome

    - by John Edwards
    I am using JQuery ajax to load images from a url, display them, and then place a button on top of each image. The code works in firefox, but in chrome, the div parent "photos" that should have all the children(one child div "photo" for each image received from the url) is 0. I have tried read() and load(), but nothing seems to work. If I run alert($('#photos').children().size()); in the Chrome console it returns the children. But at execution it returns 0. Any ideas? $(window).load(function () { $("p").text("The DOM is now loaded and can be manipulated."); //returns 0 in chrome, but 10 in firefox alert($('#photos').children().size()); $('#photos').children().each(function() { //do stuff

  • upload a image and insert directly into CKEditor

    - by Timmeh
    I'd like to create the same kind of function tumblr has for uploading images and then inserting them directly into the WYSIWYG editor. I was planning on using uploadify to upload the image, then I am not sure of the method for inserting into the CKEditor. Has anyone done anything similar or know of a plugin that could do this? Ideally I'd like it to insert the image wherever the text cursor was last placed. Thanks in advance, Tim

  • How do you chain functions dynamically in jQuery?

    - by clarke78
    I want to loop through an object that contains functions which will execute one after another. My most ideal approach would be to have these chain somehow (ie. func2 waits for func1 and func3 waits for func2) but this needs to happen dynamically and the functions will all have different durations. I'm using jQuery so I thought that perhaps "queue()" may help but I haven't worked with it much. A main concern is to not add any scope/callbacks to the functions within the object. I'd rather somehow enclose them within a parent function to execute within the loop in order to create the callback/chaining. Here's an example of what I've got now, but dumbed down. Thanks for any help! var obj = [ {'name':'func1','callback':function(){ alert(1); }}, {'name':'func2','callback':function(){ alert(2); }}, {'name':'func3','callback':function(){ alert(3); }} ]; $.each(obj, function(x, el) { el.callback(); });

  • Adobe AIR canvas dimensions messed up

    - by Nikhil
    I'm messing about with Canvas in Adobe Air. But their seems to be some issue with the mouse coordinates. The more I click towards the right, the difference between the draw position and actual click increases. My code is Wb.canvas.fillRect(evt.clientX-canvasTag.clientX, evt.clientY-canvasTag.clientY, 50, 50);

  • Are AJAX calls to a sub-domain considered Cross Site Scripting?

    - by AaronPresley
    I have Server A (www.example.com) sending information to Server B. I can only have HTML / JS on Server A (and have to do the "crunching" on Server B) so I'm trying to send form data via AJAX (trying to avoid a form post to Server B - don't ask). Obviously doing an AJAX call cross-domain is considered XSS and a big no-no, but if I were to put Server B in a subdomain (sub.example.com), would that be considered okay? How are cross-domain errors detected? Does the browser look up DNS records? IP address? Thanks in advance for you help.

  • Image visualization with canvas. How to resize them?

    - by Luca Matteis
    I'm building a website photo gallery for a friend. Images are loaded as simple DOM image objects (<img src="" />), and the size of these images is based on the browser size. So I resize them with CSS. This isn't an optimal solution since CSS resizing seems to change the quality of the image and pixelate it quite a bit. I was thinking of rendering the image with canvas and then resize it with that so that the quality remains effective, but I can't find any info about this online. Any ideas?

  • jquery animate boxshadow

    - by mstef
    http://jsfiddle.net/mstefanko/w5aAn/877/ Below, i'm achieving the effect I wanted, but with a pending issue. Since i'm using a separate span and positioning it absolute over-top of a box with relative position. I can not access the inputs until after the animation is finished. I'm guessing the only way to alleviate this would be do something similar with just animating the border of the outer box? But nothing I was doing to animate box-shadow:inset was working. HTML <div id="wow"> <span id="pulse"></span> <input id="form-input"/> <input id="form-input"/> </div>? CSS #wow { width: 500px; height: 200px; display: inline-block; position: relative; border: 1px solid black; } #pulse { width: 100%; height: 100%; box-shadow:inset 0 0 20px #6c95c3; -moz-box-shadow:inset 0 0 10px #6c95c3; position: absolute; z-index: 20000; } JS $('#pulse').stop().animate({"opacity": 0}, "fast"); $('#pulse').effect("pulsate", { times:4 }, 500, function() { $(this).remove(); });

  • getting the names of elements in JS/jQuery

    - by Mala
    I have some checkbox inputs like so: <input type="checkbox" name="1" class="filter"/> <input type="checkbox" name="2" class="filter"/> ...etc... I'm trying to write a function where any time a checkbox is selected, it generates a string with all the names concatenated. Here's what I have so far: $('.filter').click(function(event){ var filters = $('.filter').toArray(); var fstr = ""; for (f in filters) { fstr = fstr+","+f.name; } alert(fstr); }); The names keep coming up as 'undefined', though (i.e. the alert returns ,undefined,undefined,undefined,undefined,undefined,undefined). How do I access the names?

  • Loading jQuery multiple times in the same page

    - by Winaji
    I'm implementing a plug-in that's embeddable in different sites (a la Meebo, Wibiya), and I want to use jQuery. Problem is, the site I'm embedding to, may already have a jQuery script loaded. The question is, what's the best approach for this kind of problem: Should I just check if jQuery is already loaded and if so, use the original site's jQuery, otherwise load it myself? If I use this approach, am I not risking comaptibility problems (i.e. the site uses an old version of jQuery)? Should I load jQuery myself (whether it's already loaded or not) and call "jQuery.noConflict(true)" when it's finished loading? If so, how can I make sure that my jQuery has finished loading (hooking to the onLoad event doesn't seem to work all the time, and polling for "jQuery" won't work for obvious reasons)? Should I do something else? Thanks.
