Checking if a GET Variable is set - HOW?

[scottrichardson]

Hi guys.

Great site. This site has helped me many times before. But now I have a question to which I am yet to find an answer.

In a nutshell, I need to know how to check if a URL GET variable has been set, and if it has, to set the style of a DIV to display: block;

for instance: www.scott.com/competition.aspx?mode=entry

so.. the GET variable is mode and the value is entry

I would like to know how to check for that variable using javascript, then to have it change the style of my DIV with ID = "entryform" to be visible.

I know this may be a simple one.. but I just can't find anything about checking for GET variables in javascript.

I cannot use ASP, .NET or PHP to do the check.. as I'm working in an HTML template for a CMS.

Any help is greatly appreciated,

thanks in advance,

Scott

Use the location.search property. Split the string using .split("=") to get the variable/value pair.
