因此，我正在爲自己設計一個網站，它通過表單從用戶處獲取用戶輸入，在數據庫中搜索相同的內容，並返回預期的輸出。在HTML中重新輸入表格輸入
下面顯示的是我的HTML代碼相同。
<%@ page import="java.sql.*"%>
<%@ include file="DBConn.jsp" %>
<%@ page import = "java.sql.*"%>
<%
String ID,time,result,obj;
Statement stmt,stmt2;
ResultSet rs;
String SQL="";
String k="key";
String w="wallet";
String p="pen";
String a="atm";
ID="";
time="";
result="";
String save=request.getParameter("bSave");
String delete=request.getParameter("BDelete");
String search=request.getParameter("BSearch");
stmt = con.createStatement();
if (search!=null)
{
obj=request.getParameter("ID");
if(obj.equals(k))
{
ID="05447646";
}
else if(obj.equals(w))
{
ID="05447647";
}
else if(obj.equals(p))
{
ID="05447649";
}
else if(obj.equals(a))
{
ID="05447650";
}
rs=stmt.executeQuery("Select * from tablename1 where ID='"+ ID +"'");
while(rs.next()) {
ID=rs.getString("ID");
time=rs.getString("time"); }
}

這是實際頁面的樣子：
那麼這頁基本上做的是，當用戶在表單中輸入的值（有效值是筆， key，atm，wallet），它將檢索筆訪問的最後一次以及已存儲在數據庫中的TAG_ID。雖然我可以輕鬆地檢索這兩個值。我不知道如何在第一列「OBJECT」中打印對象的名稱，它應該打印有效的對象（如筆，錢包，atm，鍵）
我應該在這部分代碼，實現相同。 ：
<table align="center" width="800" style="border:10px solid #d2d2d2">
<tr><th align="center"><h3><u>Object</u></h3></th><th width="234" align="center"><h3><u>Tag-ID</u></h3></th>
<th width="394" align="center"><h3><u>Last Accessed Date and Time</u></h3></th></tr>
<tr></tr>
<tr><td align="center"><script type="text/javascript">
what goes here ..???
</script>
</td><td align="center"><%=ID%></td>
<td align="center"><%=time%></td>
</tr>
</table>
我已經嘗試過使用Document.getElementbyID但那不起作用...！是的，那裏也沒有驗證.. !!
是的，我知道，但同樣沒有驗證.. !!我只需要把它與數據庫匹配時。 – rahul888
