Javascript getFullYear函数在IE 9中不起作用

Question

If I do

function test()
    {
        var fromDate="01/17/2012";        
        var res= Test1(fromDate);
        return false;             
    }

 function Test1(d1) {


            alert(d1.getFullYear());           

        }

It is failing at d1.getFullYear() with the message

Microsoft JScript runtime error: Object doesn't support property or method 'getFullYear'

What is the problem..please help Thanks

Answer 1

The problem is that you have a string, and treat it likt it was a Date object.

Create a Date object:

var fromDate = new Date(2012, 0, 17);

or parse a string:

var fromDate = Date.parse('2012-01-17');
