Question

I am using a function where I have a readonly text input, and when I execute the function I want the number value + 1. So let’s say I have 60, when I execute the function, the number returned should be 61.

But instead it’s coming out 601, which is just adding the number 1 to the string. Any clue as to what is going on? Subtraction, multiplication and division all work fine. Here is a snippet

 var num= $("#originalnum").val() + 1;
 $("#originalnum").val(num);

And yes i’ve tried a few different variations, am I missing something?

Answer 1

A simple unary + is sufficient to turn a string into a number in this case:

var num = +$("#originalnum").val() + 1;
$("#originalnum").val(num);
