Checking if a GET Variable is set - HOW?

1 New Member
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.asp x?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.

I have the code below which parses an expression string and creates tokens. Can anyone suggest the best of error checking for things like: Valid variable only obj.attribute -whitespace allowed test( "ff*2/dd.r..ss r") #additional ..ss -invalid variable. test( "ff*$24..55/ddr") #double .. and $ -invalid number test( "ff*2/dd.r.ss r") #variable with double . -invalid variable

Are these equivelent? Is one approach prefered over the other #check to see if var contains something... if so proceed. if var is not None: continue #check to see if var is empty... if so prompt user again.

Whenever I read any C++ literature I find the words "C++ is statically type checked".OK.Agreed. Is there any language that supports "Dynamic type checking"? In such a case any type can be assigned to any other type during compile time?

The recent thread on threads caused me to reread the formal definition of SCOOP, and I noticed something I hadn't really impressed me the first time around: it's using staticly checkable rules to help ensure correct behavior in a concurrent environment. That's impressive. That's *really* impressive. I know of no other language that does that - though they probably exist. I'd be interested in references to them. Normally, I think of...

Hello, Ok I have 2 classes in my project, one is the main form and one is a connection class, at a certain event on my main form a new instance is made of the connection class, and a reference to the main form is passed to its constructor. The connection class opens up a new thread and starts doing work in it, and adds collected data to the main form via a (cross-thread) control invoking delegate.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows.

For most users, this new feature is actually very convenient. If you want to control the update process,...
