Uncaught ReferenceError: $ is not defined?
How come this code throws an
Uncaught ReferenceError: $ is not defined
when it was OK before?
$(document).ready(function() {
$('#tabs > ul').tabs({ fx: { opacity: 'toggle' } });
$('#featuredvid > ul').tabs();
});
Results in tabs don't close anymore.
jQuery is referenced in the header:
<script language="JavaScript" type="text/javascript" src="<?php echo get_option('siteurl') ?>/js/sprinkle.js"></script>
<script language="JavaScript" type="text/javascript" src="<?php echo get_option('siteurl') ?>/js/jquery-1.2.6.min.js"></script>
<script language="JavaScript" type="text/javascript" src="<?php echo get_option('siteurl') ?>/js/jquery-ui-personalized-1.5.2.packed.js"></script>
您应该首先将参考引用到jquery脚本。
<script language="JavaScript" type="text/javascript" src="/js/jquery-1.2.6.min.js"></script>
<script language="JavaScript" type="text/javascript" src="/js/jquery-ui-personalized-1.5.2.packed.js"></script>
<script language="JavaScript" type="text/javascript" src="/js/sprinkle.js"></script>
You are calling the ready function before the jQuery JavaScript is included. Reference jQuery first.
This is what solved it for me. Originally I went to Google and copied and pasted their suggested snippet for jQuery on their CDN page:
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
The snippet does not include the HTTP: or HTTPS: in the src attribute but my browser, FireFox, needed it so I changed it to:
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
Then it worked.
