How to use comparison operator in Javascript for two input values

Question

I want to compare the two input values, just try in javascript, but it\'s not working fine. I\'m using the following code

function check_closing()
{
var opening         


        

Answer 1

First of all you you need to convert the strings into integers

function check_closing(){
    var opening = parseInt($('#opening').val(), 10);
    var closing = parseInt($('#closing').val(), 10);
    if(opening > closing){
        alert('Opening is greater than Closing. Please enter the correct value');
        $('#closing').val('');
    }
}
