JavaScript - Javascript Craps Out While Handling Events

I am using a freebie script that changes css elements using onClick when you hit a button.

I have 12 choices I want to add, and don't want 12 buttons, but rather a dropdown list.

2 button examples (and js code) is:
<input onclick="changecss('li','background','url(images/list_02.jpg) no-repeat 10.2em .12em')" value="Change to BG 2" type="button" />
<input onclick="changecss('li','background','url(images/list_03.jpg) no-repeat 10.2em .12em')" value="Change to BG 3" type="button" />


How do I convert this to a SELECT list??

Thank you!

in the attached photos you have a wheel of colors and a corresponding cascading menu. I'd like to just be able to onmouseover one of the 8 colored polygons within the wheel, have it replace the wheel with one of 8 new images depending on which polygon the mouse is over, and at the same time, light up the corresponding image on the cascading company menu group. is this possible with javascript? links to a tutorial?

I've had some experience with replacing one image with another onmouseover, but not with breaking up one image into 8 parts, each with a separate image replacement. I could see how you could perform this with only 4 different colored polygons, but not 8.

Hi all,

The question is hopefully relatively simple. if I have an object say
Code:

[
var SampleObject = function(id){
  SampleObject.id = id;
  SampleObject.age= 22;
}

Is there a way to create an event that triggers every time the age member value changes?

Thanks
Ollie.

Hello,

I have a question about the cut and paste javascript events calendar
at http://www.javascriptkit.com/script/...calendar.shtml
Is there any way to add links to the event description that appears in the box below the calendar?

Thanks for your help.

Hello

I need help regarding capturing page events(mouse click ,navigation) etc on web pages and write them into a text file (using javascript). One way is using javascript events and writing them into text file. Is there be a better way of doing this ??

Hi,

I think the problem I am having is an event not a css issue, so I hope I posted in the right forum.

What I am trying to achieve is the capability to provide multiple instant chat messages. I have the php/ajax for the instant messages, what I am not sure is how to be able to view multiple chats.

What I have started to do is limit it to five possible instant chat messages and have five divs in place with visibility hidden. It works fine for one.

But if someone clicks on the name of a person they wish to chat with, the way I am currently doing it, I would need to find out:
1. which divs were free to start an instant chat in (I have no idea how to do this with divs)?
2. Having identified it I will need to change the visibility so it suddenly becomes visible

I guess firstly am I going about this the right way to be able to host/view multiple chats?

My code is below.

If I have left anything out which might be helpful please let me know. I just got stuck on the logistics side of figuring out how was the best way to make this happen, any pointers would be great.

Can we have two onFocus javascriptscript events for single HTML Tag? Thank you..

without outside extensions, how does one debug javascript events on a webpage that primarily relies on unobtrusive JS events?

for instance, i have a website i log into that has a "submit" button. the button itself only has this code:

Code:

<input type="image" class="png" tabindex="5" value="Go" src="login.png">

obviously, the only way that it can submit the form is to use javascript. and it's obviously unobtrusive in this case.

consider the fact that it isn't my webpage, and i don't want to try to put random breakpoints everywhere blindly.

any help!?

HTML TARGET:

Code:

<div id="login_link" style="margin-top:-142px;margin-left:245px;height:142px;">
		<img id="login_link" src="menu_button.png" /><a href="#"><img src="menu_button.png" /></a></div>
</div>

I'm trying to get menu_button.png to change to menu_button2.png on mouseover... I'd also like it to play a sound on click like "click.wav" I can't rename the div because it controls the slider

Heres my current project table:

http://bit.ly/dbwH23

I tried to put it in a span and have the span referance to the next tag but it didn't seem to work at least not in firefox. I'm going to keep lookin around but i'm not used to these types of code structure.

I was thinking of Embeding a flash file inside the div instead but that might be overkill. Anyone know of a solution that might work?

I can get this code to take two separate sections of a file which are not beside each other and write them into another file. It always comes up as a single full line of the code instead of the sections I want. The code includes the student number first name last name and three results of assignments. I want the code to write the student number and three results of all the students into a file and then work out the average of the student results. Can you help?

Code:

 try{                    
               while (in.hasNextLine())
               {
                  String line = in.nextLine();
                  out.println( line);
                  int i=0;
                  if(!Character.isDigit(line.charAt(i)))  { i++; }
                  studentStringNumber = line.substring(0, i);
                  String stringResult = line.substring(i);
                              	
                  studentStringNumber = studentStringNumber.trim();
                  stringResults = stringResults.trim();
                  double stringResultsValue = Double.parseDouble(stringResults.trim());
                  stringResults = in.nextLine();

                  Scanner lineScanner = new Scanner(line);
                  studentStringNumber = lineScanner.next();
                  while(!lineScanner.hasNextDouble())
                  {
                     studentStringNumber = studentStringNumber+ " " +lineScanner.next();
                  }
                  stringResultsValue = lineScanner.nextDouble();     
               }
            }

Hi

I am new to Javascript. I am working in keyboard Event handling.
i dont know how to handle multple keys pressed or sequence of keys pressed.

Want to know more about key holding , key Listener.

Hi everyone;
I have created a JavaScript function to show either a enabled or a disabled text input field depending on whether a checkbox has been clicked or not. It works great for that purpose. However, when I use it for more than one text input field and I submit the form, it goes back to its disabled form. This is a problem if you by mistake submit the form without filling all the fields. As I said, the submit button makes the form go disabled. Is there a way to either not have the form go disabled after submission or to have a "Oncheck" function so I can use $_SESSION to keep the checked attribute?
Thanks in advance for all your help

I've used js only for simple form validations thus far. I've been working on a coldfusion/ajax dynamic select list for a few days and just about have it functioning the way I want it.

My question is this. Whats the best way, if any, to handle users who turn js off. What I mean is, I have so far three separate queries for my three select lists, and are populated with ajax calls. Is there a way to get the same functionality with standard queries and page refreshes in case a visitor does have js disabled?

Thanks for any tips and advice.

i have a link that references: <a href="My_Video.asx">video</a>. when you click, video will open in the "windows media player" and the parent window goes blank.

how can i prevent the parent window from going blank?

thank you for help
