這樣改寫還是失敗
無法船直到JSP
可是我改寫小程式
<%--
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"
http://www.w3.org/TR/html4/loose.dtd">
<html>
<script type = "text/javascript">
function sendRequest() {
var url, qs;
var name, passwd;
xmlhttp = createXMLHttp();
if (xmlhttp) {
passwd = aForm.passwd.value;
name = "ee";//指派ee給name
url = "test.jsp?";
qs = "account=" + name + "&passwd=" + passwd;
//alert("url = " + url);
xmlhttp.onreadystatechange = showMsg;
xmlhttp.open("POST", url, true); // 非同步傳輸 + POST
xmlhttp.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded");
xmlhttp.send(qs); //查詢字串
}
}
function createXMLHttp() {
var xhr;
try {
xhr = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xhr = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e1) {
try {
xhr = new XMLHttpRequest();
} catch (e2) {
xhr = null;
}
}
}
return xhr;
}
function showMsg() {
var strMsg;
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
strMsg = "<hr>已成功接收，伺服器的回傳結果是：<p>" +
xmlhttp.responseText;
document.getElementById("disp").innerHTML = strMsg;
}
}
</script>
<form id="aForm" action="test.jsp">
帳號：<input name="account" size="20"><br>
密碼：<input name="passwd" type="password" size="10"><p>
<input type="button" value="送出去" onClick="sendRequest()">
<input type="reset" value="這次不算"></p>
<div id="disp"></div>
</form>
</html>
把 url = "test.jsp"; 改寫 url = "test?.jsp";
<%@ page contentType = "text/html; charset=big5" %>
<%
request.setCharacterEncoding("UTF-8");
String strName = request.getParameter("account");
// strName = new
String(request.getParameter("account").getBytes("ISO-8859-1"));
out.println("<h2>");
out.println(strName + ", 你好！<br>");
out.println("你的密碼是：");
out.println(request.getParameter("passwd"));
out.println("</h2>");
%>
都能把javascript傳值(post) jsp
請問大家是哪邊出問題
