function imageReplace ( str ) {
var arr = str.split('');
var returnArr = new Array();
for(var i in arr ){
returnArr.push("image"+arr[i]);
}
return returnArr;
}I think thats what your looking for

Dear your coding not working. dd=123 how to create function convert 123 to image if 1=image1 if 2=image2 if 3=image3 best regards

I don't know what that means... perhaps updating the question with a little more info. I just took a stab at what I thought you meant.

dear sir. example var dd=312 .so i want to convert dd value to image.if dd=3 so ur coding catch image3.gif, if dd=1 ur coding catch image1, if dd=2 so ur coding catch image2. Best regards

Result=dd=312 (image3.gif,image1.gif,imag2.gif)

this function returns an array like this, ['image3', 'image2', 'image1'] you want it to return a string like "312 (image3.gif,image1.gif,imag2.gif)"?
Hard to answer because of the lack of expected flow control, but something like this:
function concatFilename(str,index)
{
return 'image'+str[index];
}
Usage:
var dd = 'abc123';
for (var i=0; i < dd.length; i++)
{
console.log(concatFilename(dd, index));
}
Or... easier:
dd[2] = 'c';

Does dd contain a single number, to be converted as a whole? If so:
var dd = '123';
dd.replace(/([\d]+)/, /image$1/); // 'image123'
If you want each digit to be converted:
var dd = '123';
dd.replace(/([\d])/, /image$1/); // 'image1image2image3'
Hope that helps. :)
Honestly, I'm assuming you almost certainly want the first of the two. (If in doubt, ask yourself -- what behavior do you expect if you're on image 10 or 11?)

some dd=34433 is random number sir.

Then you want the first of the two code samples I offered. It will work for any arbitrary positive integer.
user730815
can you provide full script ?
Luke Sneeringer
What full script? I only wrote code specifically to answer your question.
You can use a regular expression to replace each digit with an image tag:
dd = dd.replace(/(\d)/g, '<img src="image$1.gif" alt="$1" />');
This also works on a string containing numbers, like "Page 12 of 42" is turned into "Page <img src="image1.gif" alt="1" /><img src="image2.gif" alt="2" /> of <img src="image4.gif" alt="4" /><img src="image2.gif" alt="2" />".

var getImages = function(s) {
var images=[], ss=(""+s).split(''), len=ss.length, i;
for (i=0; i<len; i++) {
images.push("image" + ss[i] + ".gif");
}
return images;
};
getImages(123); // => ["image1.gif", "image2.gif", "image3.gif"]
getImages(42); // => ["image4.gif", "image2.gif"]
getImages(0); // => ["image0.gif"]
[Edit] or perhaps something like this?
var getImageNames = function(s) {
return (""+s).split('').map(function(x) {
return '"image'+x+'.gif"';
}).join(' ');
}
getImageNames(123); // => '"image1.gif" "image2.gif" "image3.gif"'

@user: something like
getImages(123).join(' ')? I am not sure what you are asking - please update your question with more details for all to see.user730815
this is result ["image4.gif", "image2.gif"] i dont need symbol (,).how can i replace , to blank....best regards
maerics
@user: the result is an array, try using its "join" function, per my updated answer.
