Javascript quetion

is there any way to get a id that was created dynamically into a JavaScript function

i know its possible to get a specified id using document.getElementById

is there a function similar or a similar method for getting id on the fly

any help would be greatly appreciated

thanks

 

Why won't "document.getElementById" work?
Show us a bit of your code and what you're trying to do.

 

well

the code goes like this

the HTML

these are created from items in a database

<img id="label1" src="http://www.example.com" />

<img id="label2" src="http://www.example.com" />

<img id="label3" src="http://www.example.com" />

i have no problem passing the id from the images onclick to the java code, the problem is getting it to be dynamic. document.getElementById would only work for the id you specified

like below

the java

document.getElementById(label1)

//because from what i understand you must specify an id when using document.getElementById... therefore it can never be dynamic it would always be the same. this code would only get the first id (label1) out of the three

i also tried this

document.getElementById(label1)
document.getElementById(label2)
document.getElementById(label3)
this didnt make any difference, instead all it did now was get the id of the last image (label3). and never paid any attention to the first two calls

 

What are you trying to do after you get the id?
You need to store the values using an array

[COLOR=#000000][FONT=courier new]var images=new Array(); [/FONT][/COLOR]
[COLOR=#000000][FONT=courier new]for(i=0; i<3; i++){
var increment = i+1;
images[i]=[/FONT][/COLOR][COLOR=#111111]document.getElementById('label'+increment);[/COLOR][COLOR=#000000][FONT=courier new]
}[/FONT][/COLOR]

Code (markup):

images[0] will be the first <img>
images[1] will be the second <img>
images[2] will be the third <img>
.... and so on

 

so here is the original code inside the java file
maybe yo understand it bettere than i do

var button = document.getElementById('button');

switch(button.name)
{
case 'button0':
button.src = 'images/1.jpg';
button.name = 'button1';
break;
case 'button1':
button.src = 'images/0.jpg';
button.name = 'button0';
break;
}


can i use your code to do the same thing

 

Still not understanding what you're trying to do.
