Javascript, Detect DIV Height

Jun 19, 2006

I am very new to javascript, it is on my list of things to learn... but I have a wide range of other traditional programming languages so I understand functions, etc

however in the mean time I am looking for a way to detect the height of a specific div.

My goal is that I have a div that is set to overflow: auto ,

If the content of the div goes beyond its set height, I would like to make a div visible. So basicly I need to get the height of a div element, and compair it to a pixel number.

To go a step beyond, it would be cool to make the div that is visible when there is scrolling, to disapear once you got to the bottom of the div.

Any ideas?

Detect Picture Width And Height In A Page?

Nov 17, 2009

i am using jquery to detect picture width and height in a page. if the size exceeds a specified value, then a maximum size will be assigned to the <img > attribute.

this jquery is run with $(window).load, because when $(document).ready the pictures may not be loaded and the script may fail

this theory is good. however, if the internet speed is slow, or the picture link is dead, user would have to wait for a long long time before the jquery executes.

is there any way to do the resizing job wisely? for example, resize each picture once each of the pictures is loaded?

Detect URL & Detect Something On Page & Show Content Accordingly?

Feb 14, 2009

Can Javascript be used to detect a certain url and then "not" write some html according to that url and also detect something on the page and "then" display some html?.

Example: I'm working on a volusion site that uses asp. There's basically only one page that's changed dynamically. I would like to display some html when and only if the cart has any items in it. But also not to show up on the check-out pages.

The page dynamically displays "Your cart has 1 item in it..." when the visitors puts something in their cart.

So could javascript detect when this is displayed then write some html and then also detect if the url is showing the cart and then not show the html?

how I might use JavaScript to detect the overflow of text in a DIV. Currently, I have the CSS set to Code:

However, having scroll bars are pretty tacky. Instead, I'd like to be able to detect the overflow, which would then add a small <a href> link that says "More."
