我怎麼能去到預覽頁面，從註冊頁面並返回從預覽頁面註冊頁面進行修改
我要註冊在MySql數據庫的基本信息。但是在註冊數據之前，我希望用戶預覽值，如果他符合他所返回的值，則返回並修改其信息。我想用Ajax來做，而不需要重新加載頁面。
utils.js
function createRequest() {
try {
request = new XMLHttpRequest();
} catch (tryMS) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (otherMS) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = null;
}
}
}
return request;
}
function getActivatedObject(e) {
var obj;
if (!e) {
// early version of IE
obj = window.event.srcElement;
} else if (e.srcElement) {
// IE 7 or later
obj = e.srcElement;
} else {
// DOM Level 2 browser
obj = e.target;
}
return obj;
}
function addEventHandler(obj, eventName, handler) {
if (document.attachEvent) {
obj.attachEvent("on" + eventName, handler);
} else if (document.addEventListener) {
obj.addEventListener(eventName, handler, false);
}
}
Validation.js
window.onload = initPage;
function initPage() {
document.getElementById("register").onclick = registerUser;
}
function registerUser() {
document.getElementById("register").value = "Processing...";
registerRequest = createRequest();
if (registerRequest == null) {
alert("Unable to create request.");
} else {
var url = "register-feedback.php";
var requestData = "username=" +
escape(document.getElementById("username").value) + "&firstname=" +
escape(document.getElementById("firstname").value) + "&lastname=" +
escape(document.getElementById("lastname").value) + "&email=" +
escape(document.getElementById("email").value) + "&tastes=" +
escape(document.getElementById("tastes").value);
registerRequest.onreadystatechange = registrationProcessed;
registerRequest.open("POST", url, true);
registerRequest.setRequestHeader("Content-Type",
"application/x-www-form-urlencoded");
registerRequest.send(requestData);
}
}
function registrationProcessed() {
if (registerRequest.readyState == 4) {
if (registerRequest.status == 200) {
document.getElementById('wrapper').innerHTML =
registerRequest.responseText;
}
}
}
