添加日期的Java腳本不會產生結果

請有人可以幫助我已經寫了一些JavaScript，它應該將寫入我的表格的天數添加到保留的開始日期。它應該輸出回報日期。我沒有看到任何語法錯誤，但腳本無法運行。請有人幫助我找出問題的根源。添加日期的Java腳本不會產生結果

的JavaScript

<script type="application/javascript"> 
function ReturnDate(){ 
    var reservationStart = document.getElementById('ReservationStart').value; 
     var requestedDays = parseInt(document.getElementById('days').value); 
     var returnDate = document.getElementById('ReturnDate'); 
     var arrParts = reservationStart.split("/"); 
     var myDate = new Date(arrParts[2], parseInt(arrParts[1])-1, parseInt(arrParts[0]) + requestedDays, 0, 0, 0, 0); 
     var sResult = ("0"+myDate.getDate()).substr(-2)+"/"; 
     sResult += ("0"+(myDate.getMonth()+1)).substr(-2)+"/"; 
     sResult += myDate.getFullYear(); 
     document.getElementById('ReturnDate').value = sResult; 
    } 
</script>

問題是函數名是一樣的變量之一。這意味着電腦會感到困惑。

解決辦法：

的JavaScript

<script> 
    function myReturnDate(){ 
     var reservationStart = document.getElementById('ReservationStart').value; 
     var requestedDays = parseInt(document.getElementById('days').value); 
     var returnDate = document.getElementById('ReturnDate'); 
     var arrParts = reservationStart.split("/"); 
     var myDate = new Date(arrParts[2], parseInt(arrParts[1])-1, parseInt(arrParts[0]) + requestedDays, 0, 0, 0, 0); 
     var sResult = ("0"+myDate.getDate()).substr(-2)+"/"; 
      sResult += ("0"+(myDate.getMonth()+1)).substr(-2)+"/"; 
     sResult += myDate.getFullYear(); 
     document.getElementById('ReturnDate').value = sResult; 
     } 


    </script>
