regExp

[duniyadnd]

I got the following code:


var pattern = "/java/i";
if (pattern.test("JavaScript"))
document.write("yup");
else
document.write("nope");



But I keep getting this error with this code:

Object doesn't support this property or method.

Any suggestions of what's going wrong?

get rid of your quotes in the var pattern line

Just an elaboration: you can create a regular expression using a string - regexes are not strings - by calling the constructor:

var pattern = new RegExp("java" , "i");

The forward slashes (pair) indicate a regular expression literal - no constructor needed:

var pattern = /java/i;

Without either usage - no regex, so no test() method ('Object doesn't support this property or method').

Very Strange, cause the Javascript reference book I'm using has quotations.

Thanks for the help guys, works fine now.
