jquery需要是导入的第一个脚本。页面上的第一个脚本

1	<script type="text/javascript" src="/test/wp-content/themes/child/script/jquery.jcarousel.min.js">

似乎是一个jquery插件，因为jquery还没有加载到页面上，所以很可能会产生错误。

相关讨论

你需要把它放在wp_head()后面。因为这会加载您的jquery，您需要先加载jquery，然后加载JS。

相关讨论

在我的例子中，发生错误是因为我使用了错误的jquery版本。

1	<script src="http://code.jquery.com/jquery-migrate-1.2.1.min.js">

我把它改成：

1	<script src="http://code.jquery.com/jquery-1.11.3.min.js">

设置此jquery min js

1	script src="http://code.jquery.com/jquery-1.10.1.min.js"

在wp admin/admin-header.php中

相关讨论

首先，您似乎并没有将jquery本身包含在头中，而是只包含了一堆插件。对于"<"错误，不看到生成的HTML就无法判断。
