Remove the last 16 digits at the end of text

I have a string that looks like this:

Code:

[APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC)_20121104_032834

I want to remove the digits at the end of the string, basically the 16 digits at the end of the string. In the end it should look like this:

Code:

[APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC)

This is my code that I have written so far

Code:

var str="[APPLE PIE] Sei Shoujo Sentai Lakers 3 Battle Team Lakers 3 (100% FULL-PIC)_20121104_032834";
var n=str.substr(1,74);
document.write(n);

The problem is the string will be different so each will have different amount of characters. So how I remove the digits at the end of the string in javascript?

Hi,

use slice() with a negative end index:

Code:

var extr = str.slice(0, -16);

A negative index will count from the end of the string, beginning with -1. Be careful with the start index: It begins with 0, so when you use 1, you'll lose the first character.

Another possibility would be to simply take the string length and substract 16:

Code:

var extr = str.substr(0, str.length - 16);

Kravvitz agrees!
