Question

我在将havascript添加到我的HTML代码时遇到了麻烦。该代码适用于JSfiddle，但不适用于我的html代码

     <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta  http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Untitled Document</title>
<script type='text/javascript' src='http://code.jquery.com/jquery-1.9.1.js'></script>
<link href="dropdownmenu.css" rel="stylesheet" type="text/css" />
<body>


<script>

window.fbAsyncInit = function() {
    FB.init({
        appId : '593528484105939',
        xfbml : true,
        version : 'v2.2'
    });
};
(function(d, s, id){
    var js, fjs = d.getElementsByTagName(s)[0];
    if(d.getElementById(id)) {return;}
    js = d.createElement(s); js.id = id;
    js.src = "http://connect.facebook.net/en_US/sdk.se";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));
</script>

所以这是javascript代码之一，即使我将开始标记更改为，它也不起作用 <script type="text/javascript">

Answer 1

关闭Head标记，然后重试，如果仍无效，则尝试使用

<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>

<script src="//code.jquery.com/jquery-migrate-1.2.1.min.js"></script>

您可以通过替换

来使用上述两个或其中一个链接

<script type='text/javascript' src='http://code.jquery.com/jquery-1.9.1.js'></script>

<head>
    <meta  http-equiv="Content-Type" content="text/html; charset=utf-8">
    <title>Untitled Document</title>
    <script type="text/javascript" src="http://code.jquery.com/jquery-1.9.1.js"></script>
    <link href="dropdownmenu.css" rel="stylesheet" type="text/css" />
</head>

<body>
    <script>
        window.fbAsyncInit = function() {
            FB.init({
                appId : '593528484105939',
                xfbml : true,
                version : 'v2.2'
            });
        };
        (function(d, s, id){
            var js, fjs = d.getElementsByTagName(s)[0];
            if(d.getElementById(id)) {return;}
            js = d.createElement(s); js.id = id;
            js.src = "http://connect.facebook.net/en_US/sdk.se";
            fjs.parentNode.insertBefore(js, fjs);
        }(document, 'script', 'facebook-jssdk'));
    </script>
</body>

Javascript适用于JSfiddle，但不适用于浏览器
