I am creating a particle system for WebGL and have created a class to generate individual particles. Since I wanted to control the rate at which these particles were generated, i put a setTimeout function to recall the method at a given rate. However, the setTimeout never fires and loops. I was wondering if anyone could help me. BTW the javascript has been designed to mimic OOP, so its kinda of a weird setup [code]...
I have a drop down box that selects a project name. This is then taken to a javascript function that is supposed to fill in a read-only box with that name, but instead of filling it in with the project name, it fills it in with the project ID, which is how the sql database is set up. Each project has an ID, a name, and other values. Is there a way I can get the project name given the project ID in the javascript function?
My assignment for my programming class is to create a script using JavaScript that asks a user to enter a number in a pop up dialog box on their browser, and then tell them if they entered an odd or an even number. This is what I have come up with so far, whenever I test it on a browser it says that every number is even.
I would like to use JQUERY API in one of my assigned project. I am looking for open source API only, please suggest me if I can go for JQUERY or not..?
Here is a small test for all those hardcore JavaScript programmers. Is it possible to drag'n'drop a text/image element (eg. A or IMG tag) from one (I)FRAME to another (I)FRAME. This is easy & possible with IE's proprietary ondrag events. However the question is, is there a work-around using standard W3C/Firefox onmousedown, onmouseup, etc. events only? Code:
I need to implement a next to last selector for our project. I came up with the following code: jQuery.expr[':'].next_to_last = function(obj, index, m){ var $this = jQuery(obj); return $this.find(m[3]).last().prev(); }; Is there any problem with this implementation?
Very new using jQuery. Anyway, I have the following few lines which create a component on a web page.[code]...
Upon some analysis, I can see that the css does contain the styles used by my div. So now, I would like to change the colors of the component, but I am not sure what is the best practice. Can one override in the div tag the colors, or should one duplicate the .css and change it?
Seeking the best way to perform this that other in the group use.
I have a site [URL] in which i display project thumbnails on the right, by clicking it, i want that project id to open it's project photos on the left without reloading/refreshing the page. (the data/photos comes from the database using php & mysql)I tried doing that with ajax's XMLHttpRequest, but i can't execute javascript through responseText.
I have the following function that's supposed to say "Please make a guess" 20 seconds after an initial confirmation is displayed. However, it's immediately displayed as soon as someone hits "Cancel". If I change it's time to 40000 (20 seconds after the initial function is called), it does do it 40 seconds total, so it kind of does what I want. So it seems that the second setTimeout is initiated from the time the script is called generally, but I'm looking for a way specifically to have the 20 seconds start only after the "cancel" button is hit.
There are two text boxes in a HTML form.The first text box takes the time when the user starts to work on a project. The second box takes the time when the user stops working on that project.Now, I would like to calculate the total time worked on that project for that user. That is (stop time - start time). I tried few things without success.
I would like to explore a project using javascript . The project is kind of similar to the 3D Room feature on mydeco [URL] and click on 'Design a 3D room' (about a third of the way down the page). The application allows the user to position 3D items in a 3D room as well as viewing that 3D room from two additional angles. I would like to create something similar but for a different use.
Basically it would have similar features as the 3D room but with the following differences: - There would be no 3D elements/images. All would be 2D. - The 3D room builder has a panel on the right which allows users to navigate to images via categories. My app would still have the right hand panel, but the images would be 2D - The rest of the window would just have a single main 2D image in it. - The user would drop/position 2D images from the right hand panel, on to the main 2D image. - There would be no need for additional views or for any rendering of images. - It would have the other functionality at the top of the window such as save, share, undo, redo etc. An additional function would be needed to allow the user to adjust images to be 'above' or 'below' other images. Also, is there any reason this app opens in a new window instead of running on the website itself?

I'm creating a javascript class that draws triangles for a project I'm working on (none of the other vector solutions for triangles were satisfactory so I'm writing my own).
Anyway here is a small snippet of code:
Code:
The idea of the code is to create a small div in the middle of the triangle that a user can click on, pretty basic stuff.
Problem with highlighted code is, on their own they work, together they dont.
IE, if I only set the LEFT of the div, it moves across the screen to required position.
If I only set the TOP of the div, it moves down the screen to the required position.
But BOTH together (as above) just make the div dissapear somewhere. Weird.
I have to create a website as a project for my university course. Said course has nothing at all to do with computers really so it's really throwing us into the deep end as the majority of us have/had no interest in this particular field.
Regardless, I am creating a website that uses the Random Quote Generator Javascript that I copied from the Hotscripts website. The code details are below and my question is: is there any way I could change the formatting for each quote? For example, change quote 1 to be, say, yellow or bold and change quote 3 to be aligned right and blue? I mainly want to change the colour for each quote but having any other info on how to format it would be really helpful.
var quotes=new Array(); quotes[0] = "This is quote 1."; quotes[1] = "This is quote 2."; quotes[2] = "This is quote 3.";
OK, so jquery code works fine on a sample test html page. However, when I try to execute the exact same code in my asp.net project, it does not work. I have included the scripts and the paths are correct so it has nothing to do with that.
That is the section of code it gives me an error on, it says " Object doesn't support this property or method"
Also, even before I run the project, I have a warning in my error list box that says: Error updating JScript Intellisense (C:~~~blah blah jquery-1.4.2.min.js
I have done some ugly hacking in JavaScript before but nothing serious. Now I have decided to learn the language properly, so yesterday I threw together a function plotter that you can see here: balazsbotond dot hu/plotterThe script is here: balazsbotond dot hu/plotter/raphael-test.jsI use Google Chrome as my primary browser. My script works perfectly in every other browser (IE6, IE8, FF, Opera, Safari), but there are some problems in Chrome. Some functions do not work at all (exp()), some do not always work (sin(x) works, x*sin(x) works sometimes, 0.7*x*sin(x) never works). Since I am new to JS and this seems to be a very subtle problem, I have no idea where to start.
I have read that the use of eval() is not recommended because of performance and security reasons. erformance is not a problem here (eval is definitely better here than writing my own expression parser), but what about security? Did my use of eval introduce a security risk in my site (I find this quite unlikely because the whole thing runs on the client side but who knows...)?By the way, is there a way to detect if eval() was not successful?And finally, is there a reliable, cross-browser way of getting the client size of the window? I'm talking about the size without the title bar, toolbars, etc. My solution does not work in IE6 and IE8.
i have a Drop down list with 10 choices (skillset). users must choose one skillset and the corresponding level (beginer/intermediate/master). ( they have to do this 10 times for all the sillsets) what i want is :
1 - i need to show up only one record (dropdowanlist) with level then have a button to add new skill and level if required 2- then when they choose the 1st skill from the dropdown , this one will not show up on the 2nd choice dropdown.
I'm using IE6 and I've just created a simple page with this event: <body onunload="alert('sad')">
could someone tell me if this works for you if you have IE 6? I've tested this in firefox and IE 7 and they both work fine with it. but on the IE6 copy I'm testing, the event is fired only when the page is refreshed. It's not fired when I close the page...
I am using Ajax to refresh a DIV area by setting the innerHTML=request.responseText in the usual manner. in the response text I have a <SCRIPT> tag in line, but this is not executed. Is there a way of making the ajax refresh process this.
I'm trying to modify this piece of code to stop firing when I constantly mouseon and mouseout.[code]I know I need to use stop(), but I dont know where to stick it
I posted this in the UI group and was told to put it in here... My problem is that I have a function that is to call blockUI both upon login and logout. BlockUI only fires upon logout.
Here's my code:
**code** function Processing(dataString,l_processing,control) { if (l_processing == "yes") {
The code is standard $(document).ready(handler); and it doesn't fire in my script I have alert(document) to test the document object is defined and it is. I put an alert in the ready and it doesn't fire.I put an alert outside of the ready and it fires.
I am trying to build myself a blog at the moment. on the following page (http://www.thebenjamin.co.uk/) you will see little edit buttons to the left of the title. These are hyperlinks which have been disabled with the following code
var hyperlinks = document.getElementsByTagName('a'); for(var i = 0; hyperlinks[i]; i++) { switch(hyperlinks[i].className) {
