If you want to replace insensitively, make use of regex and use ignoreCase(i) flag also use word-boundaries. The string version replaces only the first occurrence and is case-sensitive.

If you want to replace all "or" regardless of their case, add g to the regex.

var k = "Red Color Or Black Color";
var s = k.replace(/\bor\b/gi,"and");
alert(s);

Oh Sorry I Forget To Use ignoreCase + Global .. anyway thanks it working greatly :D

@KarimMamdouh why would you do that? It returns the index, which isn't what's needed.

i'm using jQuery too .. for example

$(document).ready(function() {     $('textarea').keyup(function() {     var val = this.value; 	if ( this.value.indexOf("wrong") !== -1 ) {     	this.value = this.value.replace("wrong","right");
