jQuery toggle连续点击事件报错 "Uncaught TypeError: undefined is not a function"

<br> $(document).ready(function(){<br> $(&#39;#bd&#39;).toggle(<br> function(){<br> $(&quot;body&quot;).css(&quot;background-color&quot;,&quot;aliceblue&quot;);<br> },<br> function(){<br> $(&quot;body&quot;).css(&quot;background-color&quot;,&quot;aquamarine&quot;);<br> },<br> function(){<br> $(&quot;body&quot;).css(&quot;background-color&quot;,&quot;bisque&quot;);<br> }<br> );<br> })<br>

emmm，看了半天，想看看分析下。有心无力呀

注：下次粘代码的时候检查下，这完全看不懂是啥东西呀。
