我写了一个javascript代码来比较2个文本框中的2dates

     function CompareDates() {
            var fdate = document.getElementById('txtFromDate');
            var edate = document.getElementById('txtToDate');
            var FromDate = fdate.value.split('/');
            var EndDate = edate.value.split('/');
            var val = 'false';

                    if (parseInt(FromDate[1]) <= parseInt(EndDate[1])) {

                        return true;
                    }
                }
            }
            if (val == "false") {
                alert("FromDate Always Less Than …
