通过单击控制台"选项卡左上角的图标，将Firebug设置为打破所有脚本错误.
下次发生错误时，您将转到相关行. (不过，您需要先增加调用堆栈)

Set Firebug to break on all script errors, by clicking the icon on the top-left corner of the Console tab.
Next time the error happens, you'll be taken to the relevant line. (You'll need to go up the call stack first, though)

或者，在脚本中的选择器中搜索单词search.

Alternatively, search your script for the word search inside a selector.
