JavaScript dateTime string to seconds?

I'm using javascript to take a value from HTML div field that is long date in this format: "MM/DD/YY hh:mm:ss (am/pm)". So I get the value, and what I want to do is to convert that value (which is string) into seconds, and preview it in a alert box? I tried with this code, but it shows NaN

        myDivObj = document.getElementById("date").innerHTML;
        var a = myDivObj.split('/');
        var seconds = (+a[0]) * 60 * 60 + (+a[1]) * 60 + (+a[2]);

        alert(seconds);

Any ideas?

Right from W3Schools JavaScript Date object's reference page:

Date.parse()

Parses a date string and returns the number of milliseconds since midnight of January 1, 1970

Divide that by 1000 and you get the seconds.

var string = TextInput.value;
var seconds = (Date.parse(string)) / 1000;
alert("Seconds: "+seconds);

try using parseInt() to create numbers from the strings that is the output from the .split() function

    myDivObj = document.getElementById("date").innerHTML;
    var a = myDivObj.split('/');
    var seconds = parseInt(a[0]) * 60 * 60 + parseInt(a[1]) * 60 + parseInt(a[2]);

    alert(seconds);

here is a fiddle (in jQuery, I'm not much of an 'au natural' guy) http://jsfiddle.net/danieltulp/sZ9Gz/1/
