I have a javascript variable. I'd like to assign the value of it to JSTL variable.
How can I achieve it?
This is not possible since JavaScript is run in the client browser and JSTL in the server.
Your JavaScript must send the value to a servlet, one way or another.

I am trying to figure out how to get the parts of a URL I am going to be receiving from a third-party website. The URL I am expecting is something like: index.html?lob=company&ZipCode=22407
All of my pages are coded in .html rather than PHP due to my client's needs/desires, so my question is how can I get the "ZipCode" value.
In PHP this would be super simple, however I cannot do that.
Use Javascript instead.
var value_of_zipcode = "index.html?lob=company&ZipCode=22407".match("ZipCode=([0-9]{5})")[1];
now the value_of_zipcode is 22407
