• How do i create an array of unequal length arrays?

  - by Faken

  Hello everyone, I need to create a sort of 2D array in which each one of the secondary arrays are of different length. I have a 1D array of known length (which defines the number of arrays to be formed) with each element having a number that denotes the length of the secondary array in that position. Each one of the arrays are fairly large so i don't want to create a one-size-fits-all "fake" 2D heap array to cover everything. How would i go about doing this? Any 2D array I have made before are always rectangular. I'm trying to do this so that i can create some code to dynamically generate threads to split up some workload. Thanks, -Faken

• jQuery event handler queue

  - by resopollution

  Overview of the problem In jQuery, the order in which you bind a handler is the order in which they will be executed if you are binding to the same element. For example: $('#div1').bind('click',function(){ // code runs first }); $('#div1').bind('click',function(){ // code runs second }); But what if I want the 2nd bound code to run first? . My current solution Currently, my solution is to modify the event queue: $.data(domElement, 'events')['click'].unshift({ type : 'click', guid : null, namespace : "", data : undefined, handler: function() { // code } }); . Question Is there anything potentially wrong with my solution? Can I safely use null as a value for the guid? Thanks in advance. .

• Safari anchors on links not working.

  - by Keyo

  My html anchor is as follows. <a name="template-8"/> <h4 class="template" id="template-8">A title</h4> As far as I know the browser should skip to the element matching either name or id attributes. When I type in the url http://my.site.com/templates#template-8 safari jumps down the page as expected. However when linking as below the anchor does nothing. Chrome, Opera, IE7 and Firefox all work. <a href="http://my.site.com/templates#template-8">A link</a> Safari is version 5.0, could this be a safari bug?

• flex: move item around in a tree control

  - by Markus

  Hi everybody, I have a tree control and I want to give the user the ability that he can move up and down the element he just selected with a up and a downbutton. The tree gets generated from XML. I managed to insert the selected item a second time at a other place, with the following code: var parentXML:XML = XML(containerTree.selectedItem).parent(); var upperItem:XML = topContainer.source[containerTree.selectedIndex-1]; parentXML.insertChildBefore(upperItem,XML(containerTree.selectedItem)); but then I have the item there twice in the List. How can I remove to reinsert it? Thanks for Hints! Markus

• Struts2 dynamic form elements

  - by bozo

  Hi, I would like to create little higer-level framework on top of Stuts2 which can take form element description from Action and render a complete form, in order to avoid having a separate JSP files with hardcoded form elements for every form in a large web application (so if I manage to do this I will have just a few generic JSPs for data form and few for layout). Application is extremely data-driven. My idea is to create form description using custom objects in the Action (i.e. Button, TextInput etc.) and then to create a single JSP page that will render eveything out. What is the best way of doing this? Can you propose some concrete way to do this? I don't want to write something if I can reuse the existing code with some effort. Any ideas are appreciated. Kind regards, Bozo

• Passing big multi-dimensional array to function in C

  - by kirbuchi

  Hi, I'm having trouble passing a big array to a function in C. I declare: int image[height][width][3]={}; where height and width can be as big as 1500. And when I call: foo((void *)image,height,width); which is declared as follows: int *foo(const int *inputImage, int h, int w); I get segmentation fault error. What's strange is that if my values are: height=1200; width=290; theres no problem, but when they're: height=1200; width=291; i get the mentioned error. At 4 bytes per integer with both height and width of 1500 (absolute worst case) the array size would be of 27MB which imo isn't that big and shouldn't really matter because I'm only passing a pointer to the first element of the array. Any advice?

• WYSIWYG iframe editor and oninput event.

  - by teehoo

  I'm writing a simple WYSIWYG editor in an iframe, but having trouble registering the "oninput" event to detect when the user modifies the text field such as pasting in data etc. var txtArea = document.getElementById('txtArea'); txtArea.contentWindow.document.designMode="on"; txtArea.contentWindow.document.open(); txtArea.contentWindow.document.write("<head><style type='text/css'>body{font-size:13px;}</style></head><body>"+data.document+"</body>"); txtArea.contentWindow.document.close(); $([txtArea.contentWindow.document]).bind("click", updateCaretPosMouse); //fires $([txtArea.contentWindow.document]).bind("keyup", updateCaretPosKeyboard); //fires $([txtArea.contentWindow.document]).bind("input", textChanged); //doesn't fire If I create a plain old element, and add the "input" event to this, then it works. Do 'input" events not work with iframes WYSIWYG editors?

• Html string replace a span's class doesn't work in IE?

  - by SeanJA

  Someone tried to recreate smarty in js: // actually from a template file, not hardcoded in the javascript html = '<span class="{test}">yay</span>'; html = change(html, 'test', 'foo bar'); function change(html, key, value){ html = html.replace('{'+key+'}',value); html = html.replace('%7B'+key+'%7D',value); return html; } element.innerHTML = html; In FF this works fine (as expected): yay In IE 7/8 and probably 6... it gives me this: <span class="foo" bar="">yay</span> Why does it create the extra attribute instead of doing what I expected it to do?

  - by Purni

  I have a list element in my model instance. I am using Orbeon XForms. <mypage> <list name='mylist'/> <status /> </mypage> Status can be Private or Public.

I tried the following and it does not work. <xforms:bind nodeset="instance('myinstance')/list[@name='mylist']" relevant="instance('myinstance')/status='Private'" />

• Why is IE7 hiding my overflow when, as far as I can tell, all it's containing elements have overflow

  - by dougoftheabaci

  If you visit the site in question (haddongrant.com) and go to the Artwork section, if you click on an image and view it's stack in Safari, Chrome or Firefox you'll notice the images extend up and down the page, eventually disappearing over the edge. This is what you should be seeing. In Internet Explorer 7, however, the overflow gets cut off at some point before it ever gets to the end of the page. The problem is... I can't tell where! I've had a look and every containing element should show overflow. I don't know why IE7 isn't. Does anyone have any ideas where I might need to add an overflow-y:visible;?

• Dynamically assigning properties on a non data bound ASP.NET control

  - by thinknow

  For example, let's say I have a HyperLink: <asp:HyperLink runat="server" Text="Foo" NavigateUrl="foo.aspx" /> How can I set the NavigateUrl on the server side, without having to go the code-behind? This doesn't work of course: <asp:HyperLink runat="server" Text="Foo" NavigateUrl="<%= urlString %>" /> (where urlString might be a string I created earlier in the page) And this doesn't work because the HyperLink is not within a data bound control: <asp:HyperLink runat="server" Text="Foo" NavigateUrl='<%# urlString %>' /> I guess I could just use a standard anchor element: <a href="<%= urlString %>">Foo</a> But I'd rather not mix up HTML and ASP.NET controls, and it would be handy to be able to do this for other controls. Surely there must be a way?

• Drupal 6 / Views2 Grid style: whole cells link to nodes

  - by jackocnr

  I have a Users page, which is simply a nicely styled grid (HTML table) of users. I'm displaying a few fields for each one, and both the name and the profile picture have been set to link to the user node. What is the best way to change it so that the whole cell (HTML td) links to the user node? Would you have to use javascript? I've looked into modifying the theme of the view (over-riding the Style output e.g. views-view-grid--users.tpl.php), but cant see an elegant way to get the URL of the user node. And I think you would have to use javascript anyway to turn a whole block element into a link.

• Any ideas on how to implement a 'touchMoveOver' event in Javascript?

  - by gargantaun

  I'm faffing around with SVG, specifically for web content aimed at iPad users. I've created a little dial type thingy that I'm calling a "cheese board" that I'd like to use as an interface element. http://appliedworks.co.uk/files/times/SVGTests/raphael.html Clicking on a piece of cheese (to keep the analogy going) will do "something". That bit's easy. However, I'd like the user to be able to drag their finger around the 'cheese board', firing a new event (touchesMovedOver?) every time they their finger moves over a new piece of cheese. But I can't figure out how to do it since there's no 'mouseOver' equivalent for touch interfaces. If the whole thing was made of squares, I could have created some sort of 'rectContainsPoint' method to be called for every 'touchesMoved', but that approach wouldn't work here. If anyone has any idea about how something like this could be achieved, I'd love to hear it.

• twitter bootstrap typeahead ajax example

  - by emeraldjava

  I'm trying to find a working example of the twitter bootstrap typeahead element that will make an ajax call to populate it's dropdown. I have an existing working jquery autocomplete example which defines the ajax url to and how to process the reply <script type="text/javascript"> //<![CDATA[ $(document).ready(function() { var options = { minChars:3, max:20 }; $("#runnerquery").autocomplete('./index/runnerfilter/format/html',options).result( function(event, data, formatted) { window.location = "./runner/index/id/"+data[1]; } ); .. What do i need change to convert this to the typeahead example? <script type="text/javascript"> //<![CDATA[ $(document).ready(function() { var options = { source:'/index/runnerfilter/format/html', items:5 }; $("#runnerquery").typeahead(options).result( function(event, data, formatted) { window.location = "./runner/index/id/"+data[1]; } ); .. I'm going to wait for the 'Add remote sources support for typeahead' issue to be resolved.

• JQUERY nav problem

  - by turborogue

  This is part 2 of a different problem that I was having... Hopefully this is about as simple as you can get, but I'm clearly missing something..... The gist is, I'm trying to get a mouseover effect using jquery/css with a mix of background images and colors. It's mostly there, but the issue that I'm having at the moment is, I mouseover the main nav = fine, I mouseover the subnav = fine, I mouse BACK over to that same main nav element, and it's OFF state kicks in instead of remaining ON as it's supposed to... I pasted my code here (since it's kinda long, and apparently I can only paste one link....) http://tinypaste.com/2222e -- a link to my most recent efforts is at the bottom of that pastebin -- hopefully the gist of what I'm trying to do will be clear. I'll keep plugging away for a while, but any help would be greatly appreciated!!:)

• How to access ASP.NET drop down box from jquery

  - by Sayem Ahmed

  Well, I have a really small problem. How can I access an ASP.NET Drop down list from jquery? I tried to use "CssClass" property of the drop down list to assign a CSS class and then accessing that list using that class, but later I found out that the class changes when an element is selected, so my initial class replaced by a new class. I also cannot use the "ClientID" property because the part of code that access that list is not inside the page, but in a separate javascript file. So how can I access it ?

• Objective C - Constants with behaviour

  - by Akshay

  Hi, I'm new to Objective C. I am trying to define Constants which have behavior associated with them. So far I have done - @interface Direction : NSObject { NSString *displayName; } -(id)initWithDisplayName:(NSString *)aName; -(id)left; // returns West when North -(id)right; // return East when North @end @implementation Direction -(id)initWithDisplayName:(NSString *)aName { if(self = [super init]) { displayName = aName; } return self; } -(id)left {}; -(id)right {}; @end Direction* North = [Direction initWithDisplayName:@"North"]; // error - initializer element is not constant. This approach results in the indicated error. Is there a better way of doing this in Objective C.

• How to exclude read only fields using :input in jquery?

  hi guys, thus far i've only been using some basic jquery selectors and functions. but i'm looking at this clear form function and i can't figure out how to add it so i can remove hidden inputs and readonly input from getting cleared. can anybody help? thanks. function clearForm(form) { // iterate over all of the inputs for the form // element that was passed in $(':input', form).each(function() { var type = this.type; var tag = this.tagName.toLowerCase(); // normalize case // it's ok to reset the value attr of text inputs, // password inputs, and textareas if (type == 'text' || type == 'password' || tag == 'textarea') this.value = ""; // checkboxes and radios need to have their checked state cleared // but should *not* have their 'value' changed else if (type == 'checkbox' || type == 'radio') this.checked = false; // select elements need to have their 'selectedIndex' property set to -1 // (this works for both single and multiple select elements) else if (tag == 'select') this.selectedIndex = -1; }); };

• How to get rid of the double scroll bar problem when using an iframe

  - by stu

  I've seen this problem on the web, and all the suggested solutions aren't working for me, so I thought I'd come here. I have a page that has an iframe. The top of the page is a dropdown menu, the rest of the page is the iframe. The idea like I'm sure everybody else does, is to have the menu stay stationary and the menu selection runs an application in the iframe. The contents of the iframe should scroll, but the page as a whole should not. I've tried putting the iframe width=height=100% inside a single table element also with width=height=100% but I get two scrollbars if I make the window too short vertically. Any suggestions?
