function btn_click() {
//創(chuàng)建XMLHttpRequest對(duì)象
var xmlHttp = new XMLHttpRequest();
//獲取值
var username = document.getElementById("txt_username").value;
var age = document.getElementById("txt_age").value;
//配置XMLHttpRequest對(duì)象
xmlHttp.open("get", "action?user=" + <%=user%>
,true);
//設(shè)置回調(diào)函數(shù)
xmlHttp.onreadystatechange = function () {
if (xmlHttp.readyState == 4 && xmlHttp.status == 200) {
document.getElementById("result").innerHTML = xmlHttp.responseText;
}
}
//發(fā)送請(qǐng)求
xmlHttp.send(null);
}
忽然笑
