you could take a screen shot, then open it up in photoshop and measure it... or do you need to measure it in the script?

Click to expand...

No, there is no way to do this. The [tt]<body>[/tt] tag does not have a [tt]height[/tt] attribute.

I'm a freaking liar.

In your body tag, put this:

[tt]<body ... id="body">[/tt]

Then, wherever you need to determine the height, put this:

[tt]var the_height = document.getElementById('body').offsetHeight;[/tt]

I think we need to go back a few pages.


The script you were given is Javascript. You cannot just put it within the HTML and have it work.
You need to place the script between <script> tags

What the script is doing is setting a variable names "the_height" to the value of the body elements height.

to use the value you need to refer to the variable within some more javascript.

I have a feeling that you may be trying to reinvent the wheel.
what actually is it you are trying to do? WHat is your end goal?
There may well be a better way.

So now you want to, in page1.html, find out the height of page2.html, even though page2.html is not opened, so you can print the height of page2.html in page1.html?

What in the world is it you're trying to accomplish?

You certainly cannot find out the height of the [tt]<body>[/tt] tag of a page that is not opened.

You'd have to open the page, find the height, store it in a variable, then print it on the main page after (I guess) closing the popup window.
