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 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?

View 2 Replies View RelatedHere 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:
View 2 Replies View RelatedI 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.
View 1 Replies View RelatedI 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]...
View 4 Replies View Relatedwhat is "div.ui-sortable"Im using it in a project to create Igoogle panels.
View 2 Replies View RelatedThere 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.
View 4 Replies View RelatedI 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?
1. the 1st popup should open automatically and open a URL 1
2. then after 30sec the popup should close
3. then 2nd pop up window should appear and open URL2
4. then after 30sec the popup should close and so on
can any body help me with this please. I really need it.Or it can be like this also,The 1st popup should open automatically and open a URL1 then, after 30sec it should open URL2 and after 30 sec open URL3 and so on in the same popup.
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.";

I need to modify the script showed at: [URL]
Right now it allows entering "numbers only", I need it so that it allows numbers and alphabets only, no special characters or spaces.
And yes, one more question, does the first part of the code need to be added in the <head> of the document or <body> ?
The code at the above URL is as follows:
<script type="text/javascript">
// initialise variable to save cc input string
var cc_number_saved = "";
</script>

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.
$(function(){ $('ul.jd_menu').jdMenu({ onShow: loadMenu //onHideCheck: onHideCheckMenu, //onHide: onHideMenu, //onClick: onClickMenu, //onAnimate: onAnimate }); $('ul.jd_menu_vertical').jdMenu({onShow: loadMenu, onHide: unloadMenu, offset: -1, onAnimate: onAnimate}); });
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'm trying to intergrate a book that pages flip into a project I'm working on. For this I am using JFlip a plugin for jQuery.
As seen here: [url]
However two problem's I'm running into are
1. The Transparency goes really strange when I flip the page.
2. I have no idea how to set a setting to let me know what page the user is looking at.

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 am writing a script and everything works fine, except when I calculate my figure i want to display only 2 decimal points.
ie. 10 = 10.00
ie. 10.56789 = 10.56
I have no idea on how to do this and I cannot use Cold Fusion.
Is there a built in JS Function?
I'm having difficulties arithmetically manipulating form element values.
I've entered data into the form, and I fetch them using a js, as:
p7Left = Number(document.form1.elements["p7_left"].value);
p7Right = Number(document.form1.elements["p7_right"].value);
...
...
scoreLeft = Number(document.form1.elements["left_score"].value);
scoreRight = Number(document.form1.elements["right_score"].value);
Then I add these as follows:
scoreLeft = Number(scoreLeft + p&Left + ...... +);
This does what I want; without the operator 'Number' I get a concatination
of the various variables (as expected). Is there some way of globally
defining all variables as numbers instead of strings?
How do I find the row & column number of the table for a checkbox on

I have create a spinnrer (numeric up and down field) in my form. Below is the code for it:
Code:
<form action="create_session.php" method="post" name="createsession"> <!-- This will post the form to its own page"-->
<table cellpadding="0" cellspacing="0" border="0">
<tr>[code]............
Now what my question is how can I get the spinner to only allow numbers to be inputted in the spinner and not letters. Also how can I get it to only allow 2 digits to be entered in the spinner?. I know it will require an if statement but I don't know how to do it.
i'm trying to achieve is to add two numbers using do while loop. below is the code however result wont show up. i cant seem to determine the error.
<script = "text/javascript">
function myanswer(x,y){
x=parseInt(x);
