我可以获得一些解码 Facebook 页面的帮助吗？
我试图弄清楚某个特定函数在 Facebook 页面上是如何工作的，但我不熟悉 JS 语法，所以遇到了麻烦。这是问号位：
<a href="#" clicktoshowdialog="my_dialog" onclick="
(new Image()).src = '/ajax/ct.php?app_id=4949752878&action_type=3&post_form_id=3b933f46f9c4c44981e51b90c754bfce&position=2&' + Math.random();
FBML.clickToShowDialog("app4949752878_my_dialog");
return false;">
<img src="linktopicture" title="Are your friends fans?" width="190" height="230" />
</a>
<div style="display:none">
<div id="app4949752878_my_dialog" fbcontext="aa3fcff8e653">
<div class="app_content_4949752878" style="padding:10px">
<div with hidden then exposed content...
它的功能是一个图像，当单击该图像时，会弹出之前隐藏的 div。我知道该应用程序###### 被添加到 Facebook 中使用的所有 JS 之前以限制其范围。我对什么是标识的锚参数感到困惑
clicktoshowdialog="mydialog"
，它如何定位单击图像时暴露的 div？感谢您的任何澄清，如果我可以发布更多示例代码，请告诉我。
I'm trying to figure out just how a particular function works on a Facebook page, and being no friend of JS syntax, am having trouble. Here's the question mark bit:
<a href="#" clicktoshowdialog="my_dialog" onclick="
(new Image()).src = '/ajax/ct.php?app_id=4949752878&action_type=3&post_form_id=3b933f46f9c4c44981e51b90c754bfce&position=2&' + Math.random();
FBML.clickToShowDialog("app4949752878_my_dialog");
return false;">
<img src="linktopicture" title="Are your friends fans?" width="190" height="230" />
</a>
<div style="display:none">
<div id="app4949752878_my_dialog" fbcontext="aa3fcff8e653">
<div class="app_content_4949752878" style="padding:10px">
<div with hidden then exposed content...
The functionality of this is an image that, when clicked, pops out the previously hidden div. I know that the app###### is prepended to all JS used in Facebook to limit its scope. I'm confused by the anchor parameter of
clicktoshowdialog="mydialog"
What is that identifying, and how is it targeting the div that's exposed when the image is clicked? Thanks for any clarification, and let me know if I can post any more sample code.

根据wiki，它只是用于打开对话框（定义为在底部）。 Facebook 生成打开对话框的 JS。该属性经过后处理，并在此基础上生成 JS 代码（您在 onclick= 属性中看到）。
According to the wiki it's just for opening the dialog (which is defined at the bottom). Facebook generates the JS to open the dialog. The attribute got post-processed and the JS code (that you see in the onclick= attribute) was generated on it's basis.
