这jQuery隐藏功能只是不想工作 [英] This jQuery hide function just does not want to work

问题描述

这是我的浏览器看到的HTML。我想隐藏 div.embed 元素：

Here's the HTML that my browser sees. I want to hide the div.embed element:

<div id="video_div">
<img src="http://i2.ytimg.com/vi/ERF9lCf86I8/hqdefault.jpg" style="width: 200px; ">
<div class="embed">
<object width="300" height="194"><param name="wmode" value="opaque"><param name="movie" value="http://www.youtube.com/v/ERF9lCf86I8?version=3">
<param name="allowFullScreen" value="true">
<param name="allowscriptaccess" value="always"><embed src="http://www.youtube.com/v/ERF9lCf86I8?version=3" type="application/x-shockwave-flash" width="300" height="194" allowscriptaccess="always" allowfullscreen="true" wmode="opaque">
</object>
</div>
</div>

这里是我的application.js代码，用它相应的嵌入视频动态替换链接，显示缩略图，并且未成功隐藏视频：

Here's my application.js code to dynamically replace a link with its corresponding embedded video, display the thumbnail, and unsuccessfully hide the video:

$(document).ready(function() {

$('a.oembed').embedly({maxWidth:300,'method':'replace'}).bind('embedly-oembed', function(e, oembed){ 
    $("#video_div").prepend($("<img>", { src: oembed.thumbnail_url, width:200 }));
});
$('div.embed').hide();
});

这种隐藏方法不起作用真的很奇怪。任何想法为什么？

It's really weird that this hide method does not work. Any ideas why?

推荐答案

我期望上面的代码 hide 呼叫失败，呼叫根本没有执行。如果我插入假的嵌入的插件，它可以工作： http://jsbin.com/ucuru4/2

I expect the code above the hide call is failing and the call isn't getting executed at all. If I put in a fake embedly plug-in, it works: http://jsbin.com/ucuru4/2

我建议在调试器中单步执行代码。 Chrome，Safari，Opera和IE8都有内置的调试器。有Firefox的Firebug，以及VS.Net的免费版本，用于在以前版本的IE上进行调试。

I recommend single-stepping through the code in a debugger. Chrome, Safari, Opera, and IE8 all have built-in debuggers. There's Firebug for Firefox, and the free edition of VS.Net for debugging on previous versions of IE.

如果代码没问题，但是您发现 embedly call间歇性失败，可能最好将它包装在 try / catch 块中。

If the code is okay but you find that the embedly call is failing intermittently, may be best to wrap it in a try/catch block.
