方法一：

var t = "2015-03-16";
var array =  t.split("-");
var dt = new Date(array[0], array[1], array[2]);
//    var dtt = new Date(t.replace("-g-/", ""));

方法二：

var remindTime = "2008-04-02 10:08:44"; 
var str = remindTime.toString();
str = str.replace("/-/g", "/");
//// str =  str.replace("T"," ");
var oDate1 = new Date(str);
