Question

我正在尝试使用JQuery DataTables。我按照datatables.net网站上的说明进行操作，但是我做错了。

我使用的是加载引导程序和jQuery的base.html，但出现错误。

未定义jQuery

如果我查看浏览器调试控制台，可以看到jQuery已加载。 jQuery DataTables代码是在页面加载时加载的，因此应该可以。

test.html

{% extends 'layouts/base.html' %}
{% load static %}
{% load crispy_forms_tags %}
{% block extrahead %}

<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.20/css/jquery.dataTables.css">
<script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.10.20/js/jquery.dataTables.js"></script>

{% endblock %}
{% block title %}Randomization | Intense TBM{% endblock %}
{% block content %}
<div class='container'>

    <h1>DataTable</h1>
    <table id="table_id" class="display">
        <thead>
            <tr>
                <th>Column 1</th>
                <th>Column 2</th>
            </tr>
        </thead>
        <tbody>
            <tr>
                <td>Row 1 Data 1</td>
                <td>Row 1 Data 2</td>
            </tr>
            <tr>
                <td>Row 2 Data 1</td>
                <td>Row 2 Data 2</td>
            </tr>
        </tbody>
    </table>

</div>

{% endblock %}
{% block extrabody %}
<script>
    $(document).ready( function () {
        $('#table_id').DataTable();
    } );
</script>
{% endblock %}

base.html

{% load static %}
{% load widget_tweaks %}

Answer 1

通常该代码不起作用，您需要导入jquery。顺序很重要：

<script type="text/javascript" src="https://code.jquery.com/jquery-1.11.3.min.js"></script>
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.20/css/jquery.dataTables.css">
<script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.10.20/js/jquery.dataTables.js"></script>

Answer 2

我将JQuery声明放在JQquery脚本之前（见下文）再次感谢

{% extends 'layouts/base.html' %}
{% load static %}
{% load crispy_forms_tags %}
{% block extrahead %}
<!-- <script src="https://code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css"></script>
<link rel="stylesheet" type="text/css" href="https://cdn.datatables.net/1.10.20/css/jquery.dataTables.css">
<script type="text/javascript" charset="utf8" src="https://cdn.datatables.net/1.10.20/js/jquery.dataTables.js"></script> -->

            <tr>
                <td>Row 2 Data 1</td>
                <td>Row 2 Data 2</td>
