Final width of a table?

#1 September 3rd, 2008, 08:15 AM

Dear All,

I specified the table width to be 50% (regardless of whether I specify
or not), but the final width of the table will be different because of
its content.

Quesion now is how can I find out the final width?

table.width or table.style.width only returns the value that I have
specify (or null if I do not specify).

Thankd in advace!

See DOM, Firebug in FF is your best friend for this purpose...

Thanks for the answer. There is two issues.

1. I am using IIS with ASPNET, I can get the width in scrollWidth, and
clientWidth, but not offsetWidth. May I know what are the different
between these 3 values?

2. The width are not updated until it is completely render. Means if I
put a java script at the bottom of the page and try to read this
value, it will return 0. I can only read these value later (trigger by
an event, example timer / user click). Is there a better way to get
these value?

Perhaps <body onload="function-to-check-value()">

What is Bytes?
