Comparing date part only without comparing time in JavaScript

Question

What is wrong with the code below?

Maybe it would be simpler to just compare date and not time. I am not sure how to do this either, and I searched, but I couldn\'t

Answer 1

This is the way I do it:

var myDate  = new Date($('input[name=frequency_start]').val()).setHours(0,0,0,0);
var today   = new Date().setHours(0,0,0,0);
if(today>myDate){
    jAlert('Please Enter a date in the future','Date Start Error', function(){
        $('input[name=frequency_start]').focus().select();
    });
}
