我想嘗試一個lib ala jquery,但我不明白爲什麼我的方法getUrl不輸出任何內容,是嗎?javascript匿名函數:爲什麼我的腳本不工作
mylib.js
(function() {
var scripts = document.getElementsByTagName('script');
var index = scripts.length - 1;
var thisScript = scripts[index];
var myLib = {
getUrl: function() {
return thisScript;
}
}
}
if (!window.$$) {window.$$ = myLib}
)();
和mytest.html
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.0/jquery.js"></script>
<script src="mylib.js" type=text/javascript></script>
</head>
<body>
<DIV id=url>url</DIV>
<script>
var url = $$.getUrl();
jQuery("#url").html(url);
</script>
</body>
</html>
感謝我找JS很難找到錯誤:) – user310291 2012-01-30 20:08:37
