var dt_from = "2013/05/25";
var dt_to   = "2013/05/25";

if(dt_from == dt_to)
{
    alert("Both dates are Equal!");
}
else if(dt_from > dt_to)
{
    alert("From date should not be greater than todate!");
}
else if(dt_from < dt_to)
{
    alert("Okay!");
}

上述守则工作正常.但是以下代码不起作用:

var dt_from = new Date("2013/05/25");
var dt_to   = new Date("2013/05/25");

if(dt_from === dt_to)
{
    alert("Both dates are Equal!");
}
else if(dt_from > dt_to)
{
    alert("From date should not be greater than todate!");
}
else if(dt_from < dt_to)
{
    alert("Okay!");
}

这 …
