jQuery Replace All in String

By Sam Deering

Simple jQuery code snippet to replace all occurrences of characters (or strings) within a string. It could be used to find and replace all substrings found inside a string. Don’t forget to leave out the quotes on the first parameter (the g stands for global, you can also use i for an case insensitive search).

//global search in string
str = str.replace(/find/g,”replace”);
//OR global and case insensitive search in string
str = str.replace(/find/gi,”replace”);

global replace with dynamic var

//global replace
var regex = new RegExp('{'+fieldname+'}', "igm");
$itemForm = $itemForm.replace(regex, fieldvalue);
