Click the button to display the array values after the split. Try it function myFunction() { var str2=MFA/2017/; var str = MFA/2017/0001; var res = str.split('/'); var Number=res[2]; // coerce the previous variable as a number and add 1 var incrementvalue = (+Number) + 1; // insert leading zeroes with a negative slice incrementvalue = (0000 + incrementvalue).slice(-4); // -> result: 0002 document.getElementById(demo).innerHTML = str2 + incrementvalue; }
