img width

Function setToWidth()
{
var x = 0
.........code......code........code.........
return x;
}

<body>
document.write("<IMG SRC='myimage.jpg' width='setToWidth()' height='100'>");
</body>

I was hoping to set the width to the returned value from the function.

The function was tested and works perfectly.

Any help would be appreciated.

Thanks

Thanks, but unfortunately that didn't work.

You've put the function call inside the string literal. Try instead:


document.write('<img src="myimage.jpg" width="' + setToWidth() +'"
height="100" alt="Alt text here"');


By the way, document.write is a very old fashioned way of modifying the
document - try reading up on the DOM.

No it isn't.

Firstly, document.write does not "modify" the document, it's used while
the document is being parsed/created and only "adds" to the document, it
doesn't "modify" it. For this purpose it's as current now as it's ever
been, it's not old-fashioned at all. There is no better way.

Secondly, if you're talking about "modifying" the document, then you're
talking about AFTER the page has loaded. In which case, document.write
doesn't work now, nor has it ever.
