JS中如何獲取當前日期，並與輸入日期作比較

1. 首先我們獲取到"2020-5-5"類型的值
   通過Date函數轉換 var inputDate = new Date(Date.parse(realTimeEnd));

2. 獲取當前時間，直接貼代碼

                            var date = new Date(); 
                            var seperator1 = "-";
                            var year = date.getFullYear();
                            var month = date.getMonth() + 1;
                            var day = date.getDate();
                            var currentdate = year + seperator1 + month + seperator1 + day;
   

3. 變量currentdate 當前日期的字符串，下面直接轉換類型比較

                            inputDate < (new Date(currentdate.replace(/-/g, "\/")))
