Question

我是jQuery和AJAX的初学者，我只想从JSP文件中获取一个值到HTML5 所以我可以将该值放入我的HTML5源代码中的<textarea>。请帮帮我，谢谢这是源文件：

<html>
..
 <body>
<div data-role="content">
<div data-role="fieldcontain"> 
    <form method="post" action="ShowQuestion.jsp" name="frm" > <!--using post action, transfer Element Information-->   
<label for="theQuestion"></label>
 <div id="QuestionLog"> <!--to contain my question title and content-->
   <input type="text" id="qnaTitle" name="qnaTitle" > </input> <!--input title-->
<textarea cols="20" rows="5" wrap="hard" id="qnaContent" name="qnaContent">
 </textarea> <!--input content-->
     </div>       
   </form>
..
</body>
</html>

Connection conn;
PreparedStatement pstmt;
ResultSet rs=null;

pstmt = conn.prepareStatement("select * from question "); // query
rs = pstmt.executeQuery(); // execute that query 

while(rs.next()) {

   String title=rs.getString(1); //save the query's result      
   String content = rs.getString(2);  //save the query's result,too

}
}catch(Exception e) {

   e.printStackTrace(); // print the Exception Message

}

当你使用jquery时，你获得了价值（而且你确定它），你只需要做是

$('#qnaContent').val(content); // Considering that the result string is stored in "content"

如何将查询结果放入text元素和textarea元素中
