  • How to get rid of a JQUERY APPEND GIve the following code...

    - by nobosh
    Given the following lines of code which is using JQTOUCH: $('#customers').bind('pageAnimationEnd', function(e, info){ if (!$(this).data('loaded')) { $('.loadingscreen').css({'display':'block'}); $(this).append($('<div> </div>'). load('/mobile/ajax/customers/ .info', function() { $(this).parent().data('loaded', true); $('.loadingscreen').css({'display':'none'}); })); } }); How can I get ride of the .append($(' '). It used to be append($('loading') but I didn't need that and now it seems like a waste of processing time to have in the function. Is it possible?

  • is there a way to add a variable/property to a DOM element (eg, an element returned by a jQuery sele

    - by bt
    Hi there, I am looking for an alternative to using an object/variable in global scope -- I would like to associate key/value pairs with specific DOM elements (eg, a DIV), so that I can use them as input for logic that processes other elements (eg, child elements of said DIV). I tried something naive like: $('[foo=bar]').key='value' , and $('[foo=bar]')[key]='value', but it puked. Doing something like: var foobar = $('[foo=bar]'); foobar.key = 'value' -- works, but the new property/value only affects the new object (ie, foobar, not $('[foo=bar]')) Most likely there's something terribly basic I am overlooking. Any help is appreciated, thanks!

    - by majc

Some help will be appreciated. Thanks in advance!

  • How to create a gesture controlled rotating image for a UI

    - by ocdtrekkie
    I'm trying to figure out the best way to make an image rotate along with a user's finger dragging it left or right. I want to try and match the rate a user's finger is moving with the rate the image is rotating. I've got the basic setup for my application going, with the menus and whatnot I want to have, and that's all running great on the emulator, I'm just not sure how to approach this part. I can code all the logic I need for my app, I'm just not doing to well designing the UI, I have a picture in mind, I've actually made a couple mock images of it, I just can't figure out how to get it going in Android, and any help would be appreciated.

  • Recieveing "EXC_BAD_ACCESS" before any UI elements load (on device only)

    - by morgancodes
    Everything works fine on the simulator, but I gete EXC_BAD_ACCESS when I try to load my app on the device. I've put in a bunch of NSLogs to try and catch where it happens, but the log statements are never reached. Also, the UI doesn't load. So, seems the problem is happening before any of my code is reached. I tried a clean build, no luck. Also tried building and installing a different app, which works fine. So, looks like there's something wrong with my app, but it's something that happens before any of my code gets called. So, any ideas?

  • Using jQuery to make a group of images appear in order.

    - by Sean Johnson
    I have a page that shows a bunch of thumbnails (around 30), and the client is wanting them to appear one by one, in order, going from left to right on the page. This is what I've tried: var start_opacity = 500; $j('.grid-photo').each(function(i) { start_opacity = start_opacity + 500; setTimeout(function() { $j(i).animate({opacity: 1}, 4000); }, start_opacity); }); It doesn't seem to know what i is referencing. Any thoughts?

  • check for a span class content and then update the quantity using jquery?

    - by PD24
    I have code code here: //Check current if (parseInt($("#Quantity").val()) < 25) { // If it is less than 25 then set it to 25 $("#Quantity").attr("value", "25"); } It checks if the quantity box has less than 25 and if it is, adds 25 to the box. The problem is on a particular product i need to check IF my pages contains: <span class="ProductNameText">This is product ABC</span> This is a work around because the customer only has 2 products which dont require 25 quantity. Ideally i would want to check if a page contained Kit Option form fields and then add 25 to the box. Any ideas on how to check for a span and then update the quantity. But the quantity shouldnt be forced, so if the user wants 6 items they should be able to add that figure.

  • The ** idiom in C++ for object construction

    - by bobobobo
    In a lot of C++ API'S (COM-based ones spring to mind) that make something for you, the pointer to the object that is constructed is usually required as a ** pointer (and the function will construct and init it for you) You usually see signatures like: HRESULT createAnObject( int howbig, Object **objectYouWantMeToInitialize ) ; -- but you seldom see the new object being passed as a return value. Besides people wanting to see error codes, what is the reason for this? Is it better to use the ** pattern rather than a returned pointer for simpler operations such as: wchar_t* getUnicode( const char* src ) ; Or would this better be written as: void getUnicode( const char* src, wchar_t** dst ) ; The most important thing I can think of is to remember to free it, and the ** way, for some reason, tends to remind me that I have to deallocate it as well.

  • GWT: Loading different UI's based on URL

    - by jmccartie
    Trying to get a GWT project off the ground and finding it difficult to do any basic routing. Trying to fire up different UI's based on the URL. Thought I could set a string based on the getHash() and then switch off that, but seems cumbersome (and annoying since I can't do string-based switches in Java). There's got to be a best practice for this. I know Gerrit uses hashes for determining this type of information but couldn't find where they do it in the source. Or is this totally not GWT-related? Something I can handle in web.xml? Any help is much appreciated.

  • How do I add a function to an element via jQuery?

    - by Chad Johnson
    I want to do something like this: $('.dynamicHtmlForm').validate = function() { return true; } $('.dynamicHtmlForm .saveButton').click(function() { if (!$(this).closest('.dynamicHtmlForm').validate()) { return false; } return true; }); And then when I have a form of class dynamicHtmlForm, I want to be able to provide a custom validate() function: $('#myDynamicHtmlForm').validate = function() { // do some validation if (there are errors) { return false; } return true; } But I get this when I do this: $(this).closest(".dynamicHtmlForm").validate is not a function Is what I've described even possible? If so, what am I doing wrong?

  • jQuery select image in div if image parent does't have a certain class.

    - by Alex
    Wordpress wraps images with captions in a div with a class of .wp-caption. I'm looking for a way to select images that don't have this div so I can wrap them in different div. (to keep a consistent border around all the images) <div class="blog-post-content"> <div id="attachment_220" class="wp-caption alignleft" style="width: 310px"> <a href="/somewhere/"><img class="size-medium wp-image-220" src="/path/to/image" alt="" width="300" height="280" /></a> <p class="wp-caption-text">Caption Text</p> </div> <p>This is the body of the post</p> </div> To test my selector, I'm just trying to add a green border. I can handle the .wrap() once the selector is working. The most promising of my attempts is: $('.blog-post-content img').parent('div:not(".wp-caption")').css('border', '2px solid green'); ... but no luck.

  • jQuery .next() and .prev() not working as they should!

    - by Luca Matteis
    I want to get the .next() and .prev() sibling of an HTML element without excluding TextNodes. I basically need to understand if an element is directly sorrounded by <br> HTML elements. This would return true: <br> <div></div> <br> This would return false: <br> Some text <div></div> <br> BUT this needs to also return true: <br> <div></div> <br> The third example basically uses an empty TextNode, or blankspaces, or newlines. What's the best way to do this?
