Javascript regex replace function

Question

If I have the following string:

var str = "Test.aspx?ID=11&clicked=false+5+3";
str = str.replace(????????, 'true');

How can I replace the substring "false+5+3" with "true" using REGEX?

Thanks in advance!!!

str = str.replace(/false\+5\+3/, 'true');

You need to escape the + since it means something special in regex.

my problem is that 5 and 3 are set dynamically... so I actually need to replace the substring that starts from "false" and till the end of the string...

str = str.substring( 0, str.indexOf( "false" )+5 );

str = str.replace(/clicked=[^&]*/, 'clicked=true');

this will replace anything in clicked parameter, not only false+...
