javascript里时间转换

方法一：
var s = '2012-07-24 14:00', arr = s.split(' '), dArr = arr[0].split('-'), tArr = arr[1].split(':');
    var d = new Date(parseInt(dArr[0], 10), parseInt(dArr[1], 10) - 1, parseInt(dArr[2], 10), parseInt(tArr[0], 10), parseInt(tArr[1], 10))
    alert(d.getTime())

方法二：
var time = new Date("2012-07-24 14:00");
    alert(time.getTime());
