Need to get decimal places value by providing format like "0.0000" in jquery

Question

How can I get a number with decimal places according to given format in jQuery?

var format = "0.0000";
var number = "123456.78910123";

The result should be 123456.7891;

var format = "0.000"; var number = "123456.78910123";

The result should be 123456.789;

Answer 1

You can first get the length of digits (0s) after the decimal point and use that value in toFixed() function:

function getFormatted(format, number){
  var length = format.split('.')[1].length;
  return parseFloat(number).toFixed(length);
}

var format = "0.0000";
var number = "123456.78910123";
console.log(getFormatted(format, number));
format = "0.00";
console.log(getFormatted(format, number));
