Javascript replace

Javascript replace


Javascript string replace is a very useful function. Javascript has a built-in string replace function but it uses regular expressions. Here you will fint two versions of custom string replace functions (maybe more wrappers for built-in functions).

Source code for strreplace.js

// standart string replace functionality
function str_replace(haystack, needle, replacement) {
	var temp = haystack.split(needle);
	return temp.join(replacement);
}
 
// needle may be a regular expression
function str_replace_reg(haystack, needle, replacement) {
	var r = new RegExp(needle, 'g');
	return haystack.replace(r, replacement);
}
