Preg_replace

Hey everyone, im wondering how I would go about doing the equivelant of preg_replace, in javascript

basicallyt i wanna set something up so that if someone comes across the word "cat" on my site, it changes it to "kitty" or something along those lines.

help please?

 

var str=document.body.innerHTML
document.write(str.replace(/cat/, "kitty"))

thats what ive tried so far...
but it doesnt seem to be working

 

var str=document.body.whole
document.write(str.replace(/cat/, "kitty"))

i cant get this to work... ahhh

 

anyone care to reply and even say they DONT know what to do?

aye yay aye

 

what do you mean "it doesn't work"? Gives you an error? (if you have Firefox, have you checked the Error Console?) Doesn't do anything?
Also, can you please show more of your script and/or give us the URL - as your code seems fine to me...

 

Use RegExp:
