  • jQuery AJAX loaded content slideshow

    - by user369437
    Hi I have created a slideshow to go on a zencart site. The slidehow page is an external file that is loaded via AJAX. Please find the code snippet below. jQuery(document).ready(function() { //Load the slideshow page jQuery("#slidershow").load("/xxxxxxxxxx/index.php?main_page=page&id=2 #slider"); //Targetting live content, #slider is loaded via AJAX jQuery("#slider").live("click" ,function(){jQuery(this).s3Slider({timeOut:5000});}); }); Instead of live("click"...) I would like it to appear onload automatically.. But live() does not support "load". What other ways I could get the plugin to trigger onload? hope the question is clear.

  • Understanding PHP's way of reading if statements

    - by Masi
    How does PHP read if statements? I have the following if statements in this order if ( $number_of_figures_in_email < 6) { -- cut: gives false } if($number_of_emails > 0) { -- cut: gives false } if ( $number_of_emails == 0) { -- cut: gives true } The code behaves randomly. It sometimes goes to the third if clause and gives me a success, while sometimes to the one of the first two if clauses when the input variables are constant. This suggests me that I cannot code only with if statements.

  • Android drawrRect only produces squares

    - by user1905553
    I present the following code snippet: // < Android / Eclipse Kepler > // < Screen resolution: 480x800 > Graphics g = game.getGraphics(); g.drawRect(0, 0, g.getWidth()/2, g.getHeight(), Color.GRAY); Produces a square [0,0], [240, 240] (240 = g.getWidth/2 = 480/2) I expected to get a rectangle [0,0] [240, 800] Can anyone tell me if I'm wrong or if the drawRect uses width instead of height? How do I fix this? Please, if possible, test before post your answer. Help me to save a ridiculous bitmap. Thanks to all!

  • good practice for string.partition in python

    - by user1544915
    some case i write code like these: a,temp,b = s.partition('-') i just need to pick the first and 3rd element. temp would never be used. is there a better way to do this? the common case is ,a better way to pick separted element to make a new list? for example i want to make a new list use old list 0,1,3,7 element code would be this: newlist = [oldlist[0],oldlist[1],oldlist[3],oldlist[7]] it's pretty ugly,isn't it?

  • Bind event to a div appearing

    - by AndyC
    Can I create an event so I can execute some javascript whenever an element with a specific ID becomes visible or appears on the page? The element comes from a remote resource (so isn't in MY html code but appears on page load) and I'd like some code to run when it appears (and only if it appears, it may not appear every load). Thanks!

  • Are there design-time watch windows for Visual Studio 2008/2010?

    - by Jeff
    There are many times when I need to test a little snippet of .net code but rebuilding and publishing the entire project or writing a suite of unit tests just seems like overkill. For example, I am writing a regular expression right now and I want to see if it the pattern is matching on the right parts. I could go and find a million other utilities that do that sort of thing, but that is not exactly my point. FireBug has an exact analogue to what I want - the FireBug console. There is a text box where the user can enter some JavaScript and FireBug will execute it on the spot and display the return value. I would love to be able to enter something like (new Regex("b+")).Replace("abc", "x") and see the results without having to do all the overhead. Does VS have anything like this?

  • git recognizes directory as file

    - by dbarrera
    A recent issue has arised. I have my local copy of code at ~/code/ directory where I made a git init. Whenever I copied a folder with files within it, git recognized folders and files normally. But today I copied a folder and when I did a git status, git recognized hw2/ folder as a file. Additionally, I removed .git folder and reinitialized git and now every folder is recognized as file. Any ideas why this could be?

  • Separating a group of functions into an includable file in C?

    - by zebra
    I know this is common in most languages, and maybe in C, as well. Can C handle separating several functions out to a separate file and having them be included? The functions will rely on other include files, as well. I want the code to retain all functionality, but the code will be reused in several C scripts, and if I change it once I do not wish to have to go through every script and change it there, too.

  • JavaScript prototype(ing) question

    - by OneNerd
    Trying to grasp Prototyping in Javascript. Trying to create my own namespace to extend the String object in JavaScript. Here is what I have so far (a snippet): var ns { alert: function() { alert (this); } } String.prototype.$ns = ns; As you can see, I am trying to place what will be a series of functions into the ns namespace. So I can execute a command like this: "hello world".$ns.alert(); But the problem is, the this doesn't seem to reference the text being sent (in this case, "hello world"). What I get is an alert box with the following: [object Object] Not having a full grasp of the object-oriented nature of JavaScript, I am at a loss, but I am guessing I am missing something simple. Does anyone know how to achieve this? Thanks -

  • PHP: Iterate through folders and display HTML contends

    - by Mestika
    Hi, I’m currently trying to develop a method to get a overview of all my different web templates I’ve created and (legally) downloaded over the years. I thought about a displaying them like Wordpress is previewing it’s templates view a small preview windows, displaying the concrete file with styles and everything. How to divide them into rows and columns and create AJAX modal window open on preview and pagination and so on I believe I can manage, but it is the concept itself about iterate over several folders then find all index.htm / index.html pages and displaying them. I’ve not worked very much with directories in PHP and the only references and code stumps I’ve found so far is just to list all the files in a certain directory like, what it contains. I would be really grateful if someone knew about a script, a function, snippet or just could get me a nudge in the right direction to create such a (probably simple) preview function. Sincere Mestika
