JavaScript How to prevent the value to not exceed 5 chars?

use toFixed() method and pass the number to appear after decimal.

$("#tutar").text((+$("#tutar").text()+5.99).toFixed(2));

e.g. 2.55555 will become 2.56

Answer:1

First do addition, convert it to string and then use substring (as you are worried about chars only not decimal places).

$("#tutar").text((parseFloat($("#tutar").text())+5.99).toString().substring(0, 5));
