函数未定义，但显示在页面源中
我有一个在用户点击按钮时调用的函数。 Firebug一直告诉我函数没有定义，但代码在标题中：

做了一些修改，没有错，希望这有帮助。
<!doctype html>
<html>
<head>
<script>
Element.prototype.postAjax = function (params, url) {
var ajaxRequest;
try {
// Opera 8.0+, Firefox, Safari
ajaxRequest = new XMLHttpRequest();
}
catch (e) {
// Internet Explorer Browsers
try {
ajaxRequest = new ActiveXObject ("Msxml2.XMLHTTP");
} catch (e) {
try {
ajaxRequest = new ActiveXObject ("Microsoft.XMLHTTP");
}
catch (e) {
// Something went wrong
alert("Your browser broke!");
return false;
}
}
}
ajaxRequest.open ("POST", url, true);
ajaxRequest.setRequestHeader ("Content-type", "application/x-www-form-urlencoded");
ajaxRequest.setRequestHeader ("Content-length", params.length);
ajaxRequest.setRequestHeader ("Connection", "close");
ajaxRequest.send (params);
var _this = this;
ajaxRequest.onreadystatechange = function () {
if (ajaxRequest.readyState === 4) {
if (ajaxRequest.status === 200) {
_this.innerHTML = ajaxRequest.responseText;
}
else {
alert ("Error, please try again.");
}
}
}
}
window.addEventListener ("load", function () {
var button = document.getElementsByTagName ("input")[0];
var id = 1; // Don't know where you get it
var wishlist = document.getElementById ("wishlist");
button.addEventListener ("click", function () {
wishlist.postAjax ("mode=wishlist&id=" + id, "ajax.php");
}, false);
}, false);
</script>
<title></title>
</head>
<body>
<input type = "button" value = "Click me man !" />
<div id = "wishlist"></div>
</body>
</html>
多次点击：
document.body.addEventListener ("click", function (event) {
var target = event.target;
if (target.nodeName === "INPUT") {
if (target.getAttribute ("type") === "button") {
// Every single button inside your document
}
}
}, false);
这是我现在能做的最多，其余的由你决定。
