由於項目裡面需要用到Java調用PHP的儲值介面，所以學習了一下，以下這個Demo是個小小的例子，寫下來做個筆記>

jsp頁面：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"
contentType="text/html; charset=GBK"%>

<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>

<script type="text/javascript">
function getXmlHttp(){
    var http_request = false;
    if (window.XMLHttpRequest){
        http_request = new XMLHttpRequest();
        if (http_request.overrideMimeType){
            http_request.overrideMimeType('text/xml');
}
   }else if (window.ActiveXObject){
        try{
            http_request = new ActiveXObject("Msxml2.XMLHTTP");
        } catch (e){
            try{
                http_request = new ActiveXObject("Microsoft.XMLHTTP");
            }catch (e) {
            }
        }
    }
    if (!http_request){
        alert("不能建立對象！");
        return false;
    }
    return http_request;
}

function result(){
    if(req.readyState == 4 && req.status == 200){
    var names = req.responseText;
    alert("Hello:"+names);
    }
}

function checkTest(){
var name = document.getElementById("name").value;
    var ul = "http://localhost:8011/TestAjax/index.php?name=" + name;
    req = getXmlHttp();
    req.onreadystatechange = result;
    req.open("POST",ul,true);
    req.setRequestHeader('If-Modified-Since', '0');
    req.send(null);
}
</script>
