Javascript replace query string + space

Question

I grab the query string parameters and try to do this:

var hello = unescape(helloQueryString); 

and it returns:

 this+is+the+string 

instead:

 this is the string 

Works great if there was% 20, but that's +. Any way to decode them correctly so that they + characters move to spaces?

Thanks.

Answer 1

The decodeURIComponent function correctly processes decoding:

 decodeURIComponent("this%20is%20the%20string"); // "this is the string" 

Take a look at the following article:

• Comparison of escape() , encodeURI() and encodeURIComponent()

Answer 2

Adding this line after work:

 hello = hello.replace( '+', ' ' );
