Case insensitive replace all

I am looking for any implementation of case insensitive replacing function. For example, it should work like this:

'This iS IIS'.replaceAll('is', 'as');

and result should be:

'Thas as Ias'

Any ideas?

UPDATE:

It would be great to use it with variable:

var searchStr = 'is';
'This iS IIS'.replaceAll(searchStr, 'as');
Solution

  • Try regex:

    'This iS IIS'.replace(/is/ig, 'as');

    Working Example: http://jsfiddle.net/9xAse/

    e.g:
    Using RegExp object:

        var searchMask = "is";
    var regEx = new RegExp(searchMask, "ig");
    var replaceMask = "as";
    
    var result = 'This iS IIS'.replace(regEx, replaceMask);
    
    console.log(result);
