  • Ideas for band site, which technology to use?

    - by brux
    I am attempting to design and build a website for my friends band. There is minimal content to be included such as bio,news,enbemdded Audio/Visual material. My web dev expertise is average. I'm basicaly looking for inspiration, I was edging towards embedding a silverlight deepzoom xap object to add some visual stimulation, perhaps by featuring a high res photo of the bandshardware/equipment which zooms when mouseover occurs. Does anyone have any cool ideas for a central feature for this site, and which way to approact it in terms of technique (js,css,silverlight etc) If anyone has any immediate ideas which they think would be cool then I am eager to hear them! Also if anyone can link me to any cool band sites they have come across recently I would be greatful,nothing too complicated though please I will be doing all the work myself. Im want the site to be simple but have a certain wow factor!

  • jQuery Dynamic Page Loading wont work, not sure why any ideas?

  • How can I implement lazy loading on a page with 500+ images?

    - by Fedor
    I basically have a booking engine unit results page which must show 40 units and per each unit there's 1 large image of the first thumbnail and an X number of accompanying thumbnail images. I've been using the jquery lazy load plugin, but it's not thorough enough ( I'm invoking it on DOM Ready ), plus it doesn't really work in IE ( 50% of the clients use IE so it's a big issue ). What I think I really need to do is not really spit out the image but a fake element such as a span, and possibly modify my code such that if the user views the span, render it into an image element. <span src="/images/foo.gif"> The booking engine relies on JS so I think I might be forced to just rely on ajaxifying all the thumbnails and have event handlers on window scroll, etc in order for the page to be "usable" and load at an average time ( 2-3 seconds instead of 5-30s on high speed DSL/Cable ). I'd appreciate any examples or ideas.

  • How can accomplish an if else statement from the underscore template to mustache

    - by user2942566
    I have an underscore template and I have to use Mustache to render it.

How can i loop through the code to render as a mustache template. Any ideas???

  • SlickGrid V2.0 Column name/id does not follow column when dragging

    - by Brian
    I have an application (using SlickGrid) where I need to get the column name or id at any time when user clicks on a cell (this pulls up a menu specific to the data in that column/cell). Grid works fine initially but if the column is moved (drag/drop), the column name/id does not follow the drop but remains mapped to it's initial column position. Has anyone else seen this and, if so, how did you fix it? Thanks

  • jQuery UI .widgets resetting scroll positions of elements contained within

    - by Derek Adair
    I am making heavy use of jQuery UI with my latest project. Unfortunately I've hit a major wall due to some really whacky behavior exhibited by the jQuery UI widgets when they contain elements with scrollbars for overflow. Check out this demo Scroll down in one of the .scroll-container elements Click an accordion header Click on old header - note the element was auto-scrolled to the top. Is there anyway to prevent this from happening? It's screwing with a major plugin of mine that utilizes jQuery scrolling. I'm flat-out lost as to what to do here! Perhaps this is a bug worth mentioning in the jQuery UI dev forums... EDIT I am using Chrome - 8.0.552.231 and OSX 10.6.5

  • Colorbox iFrame content not appearing in IE 8/9

    - by Rocketpig
    I'm using ColorBox to call a few informational modals on-screen and given the client's requirements, the best way to do this is via iFrames (not my first choice but whatever). Everything is working peachy in Chrome, FF, etc. but the iFrame content is not working in any version of IE. The modal wrapper appears but nothing is inside. This is what I've done so far: Changed the doctype to transitional and strict for IE. No dice. Removed the "iframe: true" and replaced it with HTML "Hello". That worked fine and "Hello" appeared in the Colorbox modal. I've removed all stylesheets from the header. No luck so it's not a CSS issue. Just to be sure, I rolled back my JQuery library to 1.6.2 from 1.8.2. Nothing there, either. Any help would be appreciated. This is aggravating. Some code: $(function () { $(".modal-large").colorbox({iframe:true, innerWidth:580, innerHeight:500}); }) HTML: <div class="top-droptext"><a class="modal-large" href="modal/serviceproviderinfo.html">Update Password</a></div>

  • Minimizing server load in case of many XMLHttpRequest calls

    - by user1888975
    I am making a website where users are to like some articles. Whenever the like button is clicked I am sending a XMLHttpRequest to the server to run a file called like_clicked.php along with the get data of article id and user id. This file takes article id and user id and updates the sql database and also adds a node in an xml file related to the user. This is the first time I am doing something for mass usage. I am worried about the server load when too many users call the like_clicked.php file. Please help me, if this method is ok. I am also thinking of an alternative in case the above method fails. I am thinking of making many like_clicked files (namely like_clicked1.php, like_clicked2.php ... ) to minimize load on a single i-node. Is there a method to detect that it is better to call the next like_clicked file. Here we would need to detect how many calls per unit time are coming for the particular file. How do we handle this? Thanks in advance.

  • Heroku "We're sorry, but something went wrong." due to javascript_include_tag

    - by Newton
    Uploading my ruby on rails app to heroku causes the following error: We're sorry, but something went wrong. This does not occur on my local machine. After some debugging, I think I may have spotted the error, but do not know how to fix it. In my file application.html.erb, removing the following line solves the problem, but then my app loses its jquery mobile theme. Any ideas what I could do to fix the problem? Line causing the problem: <%= javascript_include_tag "application" %> application.html.erb file: <!DOCTYPE html> <html> <head> <title>Washapp</title> <meta name="viewport" content="width=device-width"> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.css" /> <%= javascript_include_tag "application" %> <script src="http://code.jquery.com/mobile/1.0.1/jquery.mobile-1.0.1.min.js"></script> <%= csrf_meta_tags %> <script> if (window.location.hash == "#_=_") window.location.hash = ""; </script> </head> <body> <div data-role="page"> <%= yield %> </div> </body> </html>

  • jQuery access each matched element from '.find' by an index

    - by GHarping
    Using jQuery's .find() method to return a set of elements, I am trying to access items in the returned set by their order in that set. For example, a table with two rows and in each row a select box and two text input fields, accessed with the following: $('table#tbl').find('tr.row').each(function(i) { }); To get the first element I would have thought I could use $('table#tbl').find('tr.row').each(function(i) { alert( $(this).find(':input').get(1).val() ); }); And variations of the above, but apparently this doesn't work. Could anyone suggest the correct method to access item x of n elements returned?

  • Appending target="_blank" to links in an iframe without using <body onload>

    - by CincauHangus
    I'm trying to change the links in an iframe to load in a new window instead of the iframe itself. Currently I use this code in head: $(document).ready(function() { var oIFrame = document.getElementById("iframeID"); var oDoc = (oIFrame.contentWindow || oIFrame.contentDocument); if(oDoc.document) oDoc = oDoc.document; var links = oDoc.getElementsByTagName("a"); for(var i=0; i<links.length; i++) { links[i].target="_blank"; } }); However, the code above is triggered before the iframe is fully loaded with its contents. I know this code would work if it's triggered in the body onload attribute, but I'd like to avoid that method and implement it in a function or a file instead.

  • How to hide an dom element after creating it on the fly with Jquery ?

    - by ismaelsow
    I am trying to build a form where users can add a text field by clicking on a "add option" button. They can also remove added fields by a "remove option" link created on the fly by Jquery, along with the text field. My code looks like this : $(document).ready(function(){ $("#add_option").click(function(){ var form = $("form"); var input_field = '<input type="text" />'; var delete_link = '<a href="#">remove</a>'; form.append(input_field + delete_link); return false; }); $("a").click(function(){ alert('clicked'); return false; }); }); This code is not working : when I click on the "add_option" button, a new text field and the "delete_link" appear. But when clicking on the "delete_link" created by JQuery, the browser follows the link instead of launching a pop-up displaying "clicked". Any idea ? Thanks !
