Re: [ajax] (將code寫活的)要如何利用 javascript …
我將 xhr 提出來成為一個全域變數，因為showMsg()也會用到
passwd 跟 name 的部份都暫時用數值帶入。
底下是HTML的部份，不包含JSP Code
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<meta http-equiv="content-type" content="text/html; charset=utf-8" />
<script type = "text/javascript">
var xhr;
function sendRequest() {
var url, qs;
var name, passwd;
xhr = createXMLHttp();
if (xhr) {
passwd = 'aaa';
name = "ee";//指派ee給name
url = "test.jsp";
qs = "account=" + name + "&passwd=" + passwd;
xhr.onreadystatechange = showMsg;
xhr.open("POST", url, true); // 非同步傳輸 + POST
xhr.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
xhr.send(qs); //查詢字串
}
}
function createXMLHttp() {
try {
return new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
return new ActiveXObject("Microsoft.XMLHTTP");
} catch (e1) {
try {
return new XMLHttpRequest();
} catch (e2) {
return null;
}
}
}
}
function showMsg() {
var strMsg;
if (xhr.readyState == 4 && xhr.status == 200) {
strMsg = "<hr>已成功接收，伺服器的回傳結果是：<p>" +
xhr.responseText;
document.getElementById("disp").innerHTML = strMsg;
}
}
