问题
I just loaded jQuery Tools onto my site. But the Google Chrome console shows an error:
Uncaught Error: Syntax error, unrecognized expression: [href=/] (http://cdn.jquerytools.org/1.2.7/full/jquery.tools.min.js)
The jQuery version I am using is 1.7.1
How to deal with this problem?
回答1:
I'm assuming you have a selector that is meant to match elements with an href attribute value of /. You will need to put the / character in quotes:
var elems = $("[href='/']");
Alternatively, you can escape the character:
var elems = $("[href=\\/]");
From the jQuery docs:
If you wish to use any of the meta-characters ( such as
!"#$%&'()*+,./:;<=>?@[\]^{|}~` ) as a literal part of a name, you must escape the character with two backslashes: \\.
Here's a working example. Remove the quotes to generate the same error you mention in your question.

My guess is that you changed the order of the libraries. If you want to use JQuery, its lib has to be loaded first to use an additional JQuery-Expansion-Lib. You should change the order in the <head> like this:
<html>
<head>
<link rel="stylesheet" type="text/css" href="formate.css"> //CSS always first
<script src="URL_TO_JQUERY" type="text/javascript"></script> //JQuery first
<script src="URL_TO_ADDITIONAL_LIB_1" type="text/javascript"></script>
<script src="URL_TO_ADDITIONAL_LIB_..." type="text/javascript"></script>
<script src="URL_TO_ADDITIONAL_LIB_n" type="text/javascript"></script>
</head>
</html>
