How to remove Backslash from the middle of a string

The usernames used by my organization are in the following format:

i:4#.w|abcd\1231231234.abc

I need to remove the \ and everything before it using JavaScript. I have the following code but because of the escape function of the \ in JS I find that JS simply remove \13 from the string. I have search for hours and haven't been able to find any solution. Here is the current code.

<script type="text/javascript">
   window.onload = function () {
       document.getElementById('userId').innerHTML ="i:4#.w|abmy\1391251254.abc";
   }
</script>

<div>
    <span id="userId"></span>
</div>

I need the result to be 1391251254.abc

An alternative is using the function substring along with the function lastIndexOf.

var str = "i:4#.w|abmy\\1391251254.abc"
str = str.substring(str.lastIndexOf('\\') + 1)

You can use a regex to extract the last part of your string. It will work event if the string contains more than one backslash.

var string = "i:4#.w|abmy\\1391251254.abc"; //Note the escaped '\'

var regex = /.*?\\(.*)$/;
var match = regex.exec(string);
console.log(match[1]); //1391251254.abc
