我是JavaScript新手，目前正在学习有事件处理的DOM基础知识。 这是我的HTML代码： -使用JavaScript处理事件
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en-US">

<title>My Test Program for Event Handler</title>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<body>
<p>The first captain of the USS Enterprise NCC-1701 was
<a id="t1" href="http://en.wikipedia.org/">My Link!</a>.</p>
<script type="text/javascript" src="example.js"></script>
</body>
</html>
而且，这是我的Jscript： -
var StrayClickCatcher = {
init: function() {
var links = document.getElementsByTagName("a");
if (typeof document.addEventListener != "undefined") {
document.addEventListener("click", StrayClickCatcher.strayClickListener, false);
for (var i = 0; i < links.length; i++) {
links[i].addEventListener("click", StrayClickCatcher.linkClickListener, false);
}
} else if (typeof document.attachEvent != "undefined") {
document.attachEvent("onClick", StrayClickCatcher.strayClickListener);
for (var i = 0; i < links.length; i++) {
links[i].attachEvent("onClick", StrayClickCatcher.linkClickListener);
}
}
},
strayClickListener: function (event) {
alert("Did you mean to click a link? " + "It's that blue, underlined text.");
},
linkClickListener: function (event) {
if (typeof event == "undefined") {
event = window.event;
}
if (typeof event.stopPropagation != "undefined") {
event.stopPropagation();
} else {
event.cancelBubble = true;
}
}
};
我想显示的提示信息时，用户不点击链接。但是，它不工作。我错过了什么吗？如果调用
StrayClickCatcher.init();
在你的js代码年底
为了上帝的爱，正确缩进代码。这是一个难以理解的混乱。 – casraf
你从某处调用过StrayClickCatcher.init（）吗？ – sedran
