使用Bootstrap 3，表排序和搜索文本字段无法正常工作。我基本上是在开发查询生成器并为数据创建动态表，但是表排序和搜索无法正常工作。数据显示准确，但表排序和搜索文本框不显示数据。

<p align='justify'>Users may build complex queries using the logical operators 'AND' and 'OR'. Each sub-query can be built using other operators such as LIKE, NOT LIKE, EQUAL and NOT EQUAL TO while dealing with strings like
words or letters and =, !=, <=, >=, < and > while dealing with numerical values. The Query builder aids to the flexibility of performing search on a number of fields simultaneously.</p>

答案 0 :(得分：0)
您的代码使用相对链接。不要那样做使用绝对链接！
<script src="jquery-3.3.1.js" type="text/javascript"></script>
根据该脚本所在的文件夹，它将从那里查找，而不是从站点根目录查找。
但是，将其更改为
<script src="/path/to/jquery-3.3.1.js" type="text/javascript"></script>
将始终从站点根目录加载它！在示例中，我放置了/path/to/jquery.js，如果您的index.php位于公用文件夹中，则通常将js放置在js文件夹中，因此链接将为/js/jquery-3.3.1.js
