javascript - 将日期输入 SQL 数据库

Question

我现在遇到的问题是 SQL 数据库中输入的日期是 1899 年 12 月 30 日。我使用 Access 2003 作为数据库，想不出发生这种情况的任何潜在原因!

window.status='Loading contingency scripts - please wait...';
audit('Loading contingency scripts');
var conting={ i:0

,start:function(){
    window.status='Loading form - please wait...';
    var t='';
    t+='<form name="frm_conting" id="frm_conting" onsubmit="return false;">';
    t+='<table width="100%" cellspacing="1" cellpadding="0">';
    t+='<tr><td>Date (DD/MM/YY):</td><td><input type="text" size="8" value="'+current_date+'" id="date"></td></tr>';

t+='<tr><td>Time Started:</td><td><select id="timefrom"><option></option>';
  for(h=8;h<23;h++){  
      for(m=0;m<46;m=m+15){  t+='<option value='+nb[h]+':'+nb[m]+'>'+nb[h]+':'+nb[m]+'</option>';  };
     };
t+='</select></td></tr>';

t+='<tr><td>Time Finished:</td><td><select id="timeto"><option></option>';
  for(h=8;h<23;h++){  
  for(m=0;m<46;m=m+15){  t+='<option value='+nb[h]+':'+nb[m]+'>'+nb[h]+':'+nb[m]+'</option>';  };
     };

    t+='</select><tr><td>Extension #:</td><td><input type="text" size="5" value="'+my.extension+'" id="staffid"></td></tr>';
t+='<tr><td>Desk ID:</td><td><input type="text" size="5" value='+my.deskid+' id="desk"></td></tr>';
    t+='<tr><td>Number of calls:</td><td><input type="text" size="5" id="calls"></td></tr>';
    t+='<tr><td>Avid ID:</td><td><input type="text" size="5" id="avid"></td></tr>';
    t+='<tr><td><input type="button" value="Submit" onClick="conting.save()"></td>';    
    t+='</table>';
    t+='</form>';

    div_form.innerHTML=t;       
    window.resizeTo(400,385);
    window.status='';
    }

,save:function(){
var conting_date=frm_conting.date.value; 
 if(!isdate(conting_date)){alert("You have entered an incorrect date.");return false;};

var conting_timefrom=frm_conting.timefrom.value; 
var conting_timeto=frm_conting.timeto.value; 
 if(conting_timefrom==''||conting_timeto==''){alert("You need to enter a starting & finishing time.");return false;}; 
 if(conting_timefrom>conting_timeto){alert("The time you have entered is after the finish time.");return false;}; 

var conting_staffid=frm_conting.staffid.value; 
 if(conting_staffid.length!=5) { alert("You have entered an incorrect extension number.");return false;};

var conting_desk=frm_conting.desk.value; 
 if(conting_desk.length!=5) { alert("You have entered an incorrect desk ID.");return false;}; 

var conting_calls=frm_conting.calls.value; 
 if(isNaN(conting_calls)){alert("You have not entered amount of calls.");return false;};

var conting_avid=frm_conting.avid.value; 
 if(isNaN(conting_avid)){alert("You have entered an incorrect avid ID.");return false;};
 if(conting_avid.length!=5) { alert("You have entered an incorrect avid ID.");return false;}; 

 conn.open(db["contingency"]);
 rs.open("SELECT MAX(prac_id) FROM practice",conn);
var prac_id=rs.fields(0).value+1;
var prac_staffid=frm_conting.staffid.value; 
var prac_date=frm_conting.date.value; 
var prac_timefrom=frm_conting.timefrom.value; 
var prac_timeto=frm_conting.timeto.value; 
var prac_calls=frm_conting.calls.value; 
var prac_avid=frm_conting.avid.value; 
 rs.close();
var q="INSERT INTO practice (prac_id, prac_staffid, prac_date, prac_timefrom, prac_timeto, prac_extension, prac_desk, prac_calls, prac_avid) VALUES ("+prac_id+","+my.id+", "+prac_date+", '"+prac_timefrom+"', '"+prac_timeto+"', '"+my.extension+"', '"+my.deskid+"', '"+prac_calls+"', '"+prac_avid+"')";

 rs.open(q,conn); 
 conn.close();
     alert("Your contingency times were successfully added.");
     window.status='';
   conting.start();
 }

 };
 window.status='';

1899年12月30日是Access数据库的“零”日期。

很可能 prac_date 变量不包含正确的日期时间值。它要么丢失、不完整，要么格式错误。在执行查询之前发出警报或记录它，以查看进入查询的实际值并验证其正确性。
