advanced use of images in objects

ok, noone touched my inner html issue so lets try this one.

anyone ever stored an Image inside an object?

I want to declare an object which has an image as one of it's data items.

so I created a constructor which passes the source file in. I tried

this.mypic = new Image();
this.mypic.src = src_in;

I tried

mytmp = new Image();
mytmp.src = src_in;
(which works)
this.mypic = mytmp;
(which does not)

I am trying to scour the docs and also my o'reilly book but I am coming up short here.

any ideas?

RE: advanced use of images in objects

here is a little test

here is the link
http://www.hysteriaweb.net/stuff/temp/jsxmenu2/test.html

do not worry about the graphics, watch the errors.

this is IE only please.

what I do is create an image as part of an object and assign a src to it, then I wish to use that image inside the object functions.

I use a popup alert to test the src is being set, which you see it is, then I in the function I get an error. because the this.mysrc.src (and even this.mysrc) are not defined.

I have used javascript function elsewhere just fine, and I can assign regular variables, just not Images.

what is the deal here????

thanks, hope you guys can help.

here is the code

php Code:

Original - php Code
<html> <head> <script language="javascript"> function test() { this.mysrc = new Image(); this.mysrc.src = "jsxmfolder.gif"; alert(this.mysrc.src); this.show = show; } function show() { document.write('<img src="jsxmnone.gif" onLoad="this.src = this.mysrc.src;"></img>'); } me = new test(); me.show(); </script> </head> </html>

 
<html>
<head>
<script language="javascript">
 
function test()
{
        this.mysrc = new Image();
        this.mysrc.src = "jsxmfolder.gif";
        alert(this.mysrc.src);
        this.show = show;
}
 
function show()
{
        document.write('<img src="jsxmnone.gif" onLoad="this.src = this.mysrc.src;"></img>');
}                                               
me = new test();
me.show();
</script>
</head>
</html>
