两个具有完全相同代码的 JSFiddle,但一个有效,另一个无效



以下SJFiddle工作正常。

http://jsfiddle.net/JMPerez/62wafrm7/

我创建了第二个SJFiddle来测试它,并从第一个复制了完全相同的所有内容(HTML/CSS/JS(。我也包含了相同的资源,但它不起作用。

https://jsfiddle.net/kennethcode/dz1tubf6/

两者的 HTML 是相同的

<div class="container">
<h1>Displaying User Data</h1>
<p>Log in with your Spotify account and this demo will display information about you fetched using the Spotify Web API</p>
<button class="btn btn-primary" id="btn-login">Login</button>
<div id="result"></div>
</div>
<script id="result-template" type="text/x-handlebars-template">
<dl>
<img src="{{images.0.url}}">
<dt>User Name</dt>
<dd>{{id}}</dd>
<dt>Display Name</dt>
<dd>{{display_name}}</dd>
<dt>Country</dt>
<dd>{{country}}</dd>
<dt>Followers</dt>
<dd>{{followers.total}}</dd>
<dt>Profile</dt>
<dd><a href="{{external_urls.spotify}}" target="_blank">{{external_urls.spotify}}</a></dd>
<dt>Email</dt>
<dd>{{email}}</dd>
<dt>Product</dt>
<dd>{{product}}</dd>
</dl>
</script>

JavaScript 对于两者是相同的

(function() {
function login(callback) {
var CLIENT_ID = '6b284830006843e7ae7b170725715aed';
var REDIRECT_URI = 'http://jmperezperez.com/spotify-oauth-jsfiddle-proxy/';
function getLoginURL(scopes) {
return 'https://accounts.spotify.com/authorize?client_id=' + CLIENT_ID +
'&redirect_uri=' + encodeURIComponent(REDIRECT_URI) +
'&scope=' + encodeURIComponent(scopes.join(' ')) +
'&response_type=token';
}
var url = getLoginURL([
'user-read-email'
]);
var width = 450,
height = 730,
left = (screen.width / 2) - (width / 2),
top = (screen.height / 2) - (height / 2);
window.addEventListener("message", function(event) {
var hash = JSON.parse(event.data);
if (hash.type == 'access_token') {
callback(hash.access_token);
}
}, false);
var w = window.open(url,
'Spotify',
'menubar=no,location=no,resizable=no,scrollbars=no,status=no, width=' + width + ', height=' + height + ', top=' + top + ', left=' + left
);
}
function getUserData(accessToken) {
return $.ajax({
url: 'https://api.spotify.com/v1/me',
headers: {
'Authorization': 'Bearer ' + accessToken
}
});
}
var templateSource = document.getElementById('result-template').innerHTML,
template = Handlebars.compile(templateSource),
resultsPlaceholder = document.getElementById('result'),
loginButton = document.getElementById('btn-login');
loginButton.addEventListener('click', function() {
login(function(accessToken) {
getUserData(accessToken)
.then(function(response) {
loginButton.style.display = 'none';
resultsPlaceholder.innerHTML = template(response);
});
});
});
})();

两者的CSS是相同的

.container {
margin: 1em;
}
img {
margin-bottom: 1em;
}

为什么会发生这种情况的任何线索?谢谢

检查侧边栏中的"资源"部分。第一个有以下 3 个附加资源:

  • 缓存.css
  • 车把.js
  • jquery-1.10.1.min.js

只需在html 部分顶部手动添加所需的脚本:

<link rel="stylesheet" type="text/css" href="https://developer.spotify.com/web-api/static/css/cached.css">
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/handlebars.js/2.0.0-alpha.1/handlebars.min.js"></script>
<script type="text/javascript" src="https://code.jquery.com/jquery-1.10.1.min.js"></script>
