Answer 1

Use JS String.prototype.replace first argument should be Regex pattern or String and Second argument should be a String or function.

str.replace(regexp|substr, newSubStr|function);

Ex:

var str = 'this is some sample text that i want to replace'; var newstr = str.replace(/want/i, "dont't want"); document.write(newstr); // this is some sample text that i don't want to replace
