document.getElementById(“btnSubmit”).onclick = function () {

search();

};

function search() {

var request = new XMLHttpRequest();

request.open(‘GET’,’raw_ajax_php.php?number=’ + document.getElementById(“put_info”).value ,true);

request.send();

if (request.readyState === 4){

if (request.status === 200){

document.getElementById(“content”).innerHTML = request.responseText;

}else {

alert(“请求发生错误!”);

}

}

header(“content-type:text/html;charset=utf-8”);

$numberinfo = array(“jack”,”mary”,”oliao”,”griffin”);

$number = $_GET[“number”];

if (!isset($number) || empty($number)){

echo “输入有误!”;

}

switch ($number){

case 1:

echo $numberinfo[‘0’];

break;

case 2:

echo $numberinfo[1];

break;

case 3:

echo $numberinfo[2];

break;

case 4:

echo $numberinfo[3];

break;

}

为什么没有效果呢?错在哪了?
