Javascript Replace All with Variable

Monday, December 28, 2009

Here is how you replace all values in a string with another string which is inside of a variable using Javascript:

var str = "Please change all the change words in this sentence.";

var searchfor = "change";

str = str.replace(new RegExp(searchfor, 'g'), "changed");

The resulting value for str would be:

"Please changed all the changed words in this sentence.";
