Question

I wanna replace several words in a text using replace() in javascript, how can I do that?

For example, if I wanna replace, \'Dave Chambers,

Answer 1

You'll want to use regular expressions if you want to ignore case:

var str = sometext.innerHTML;
str.replace(/Dave Chambers/ig, 'Jackie Chan')
   .replace(/David Chambers/ig, 'Jackie Chan')
   .replace(/Will Smith/ig, 'Jackie Chan');

You can do it all in one statement like above and that's how I would prefer as it's more readable.
