Question

How do you compare a value from jQuery with a fixed number?

I thought this might work but it doesn't:

if (parseInt($("#days").value) > 7) {
            alert("more than one week");
        }

Answer 1

As well as @redsquare 's answer to use .val(), you should specify the radix:

if (parseInt($("#days").val(), 10) > 7) {
            alert("more than one week");
        }

This is because the value could have a leading 0, in which case parseInt would interpret the value as octal.

Answer 2

if #days is an input then you need .val() instead of value

e.g.

  if (parseInt($("#days").val()) > 7) {
        alert("more than one week");
   }
