replace string with another string by second occurrence

Question

I have string like "key-original-original" and I want to replace it with "key-original-resized".

somebody help me with this by using regular expression and replace function in Javascript ?

developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/… Also this is a duplicated question ;) — Sander Visser

<script>
      text = 'key-original-original';

    var t=0;   
    text = text.replace(/\-original/g, function (match) {
      t++;
      return (t === 2) ? "-resized" : match;
    });
    alert(text);
</script>

You may try this:

var str = 'key-original-original';
var newStr = str.replace(/key\-(.*)\-(.*)/i, 'key-$1-resized');

Here is a pretty good tutorial on working with strings. digitalocean.com/community/tutorials/… I know you asked for a regular expression but there are many combinations to do this. If you look through the quick walk-through I am sure you'll find something of your liking.
