您可以使用此

you can use this

function CompareDates()
       {
            var fdate = document.getElementById('<%=txtAgValidFrom.ClientID%>');
            var edate = document.getElementById('<%=txtAgValidTo.ClientID%>');
            var FromDate = fdate.value.split('/');
            var EndDate = edate.value.split('/');
            var val = 'false';

            if (parseInt(FromDate[2]) < parseInt(EndDate[2])) {
                val = 'true';
                return true;
            }
            else if (parseInt(FromDate[2]) == parseInt(EndDate[2])) {
                if (parseInt(FromDate[0]) < parseInt(EndDate[0])) {
                    val = 'true';
                    return true;
                }
                else if (parseInt(FromDate[0]) == parseInt(EndDate[0])) {
                    if (parseInt(FromDate[1]) <= parseInt(EndDate[1])) {
                        val = 'true';
                        return true;
                    }
                }
            }
            if (val == "false") {
                alert("Agreement valid from date cannot be greater than Agreement valid to date");
                return false;
            }
        }
