HTML:
<input id="inp" type="text" value="some a bit longer text to demonstrate the bug" />

ECMAScript:
document.getElementById("inp").scrollWidth

Problem description:
scrollWidth doesn't return width of the text inside input. It returs the same value as offsetWidth even if text doesnt fit the space of input field.

In MS Internet Explorer it works correctly.

BTW, isn't that the same as bug 209807?

Reproducible: Always

Actual Results:  
scrollWidth ignores width of the input's content

Expected Results:  
scrollWidth shold be equal to input's content width

scrollWidth would only apply to a scrollable object, and the text input itself is not scrollable...

We could try to hack something together here for IE compat, but I'm not sure it's worth it.

Martin: How is this value useful? I.e. what would you use the value for if it was available?

Boris: Is there some other way for the user to get this value?

Not really, no.

[Martin Zdila]

I needed this to resize width of the input field to the size of this content with JS.

Comment 6

[Boris Zbarsky [:bzbarsky]]

Confirming, but maybe we want a different API here for getting that information...

Attachment: Attachment shows incorrect behaviour of scrollWidth in FireFox

I'm having same problem with scrollWidth in FireFox (3.5.7), while in IE7 this works fine - returns scrollWidth values correctly.
