Answer 1

You can use

• parseInt - Parses a string argument and returns an integer of the specified radix or base.

If parseInt encounters a character that is not a numeral in the specified radix, it ignores it and all succeeding characters and returns the integer value parsed up to that point. parseInt truncates numbers to integer values. Leading and trailing spaces are allowed.

Example:

parseInt("1025*1", 10); // 1025

Answer 2

You're looking for the split method.

For example:

var array = value.split('*');
var first = array[0];

Alternatively,

var first = value.substring(0, value.indexOf('*'));

Answer 3

Use the spli method:

var itemid=document.getElementById('item_code').value.split("*")[0];

Answer 4

This will display "1025" (will strip *1) into DIV with ID="DIV_ID":

document.getElementById('DIV_ID').innerHTML = itemid.split(/(\d+)\*\d+/)[1];
