我正在开发一个基于从互联网下载的模板的网页。这个页面包含几个包含，我不知道可以改变。
我的问题是我正在实现一个Flot图表，错误“Uncaught TypeError：$ .plot不是一个函数”总是出现。
我在示例页面上实现了相同的图表，它使用了四个包括：jquery-2.2.3.min.js，/ jquery.flot.min.js，jquery.flot.time.js和utilitarios .js（我的作者）
我认为问题可能出现在模板中的某些包含内，并且存在某种冲突。
erro行：
$.plot("#line-chart", [line_data1, line_data2],

在您的HTML输出中，您在该页面上获得了三次jQuery源代码。在您采购Flot之前，它第一次来源。
<!-- jQuery 2.2.3 -->
<script src="http://localhost/sistema/public/plugins/jQuery/jquery-2.2.3.min.js"></script>
<!-- ChartJS 1.0.1 Hídrico-->
<script src="http://localhost/sistema/public/plugins/chartjs/Chart.min.js"></script>
<!-- date-range-picker -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.11.2/moment.min.js"></script>
<script src="http://localhost/sistema/public/plugins/daterangepicker/daterangepicker.js"></script>
<!-- Flot graph (Temperatura) -->
<script src="http://localhost/sistema/public/plugins/flot/jquery.flot.min.js"></script>
<script src="http://localhost/sistema/public/plugins/flot/jquery.flot.time.js"></script>
然后在页面后面再次来源：
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.3/jquery.min.js" integrity="sha384-I6F5OKECLVtK/BL+8iSLDEHowSAfUo76ZL9+kGAgTRdiByINKJaqTPH/QVNS1VDb" crossorigin="anonymous"></script>

<script src="http://localhost/sistema/public/js/dropdown.js"></script>
然后几乎在你再次这样做之后立即：
<!-- jQuery 2.2.3
<script src="plugins/jQuery/jquery-2.2.3.min.js"></script> -->
<script src="http://localhost/sistema/public/plugins/jQuery/jquery-2.2.3.min.js"></script>
除了加载jQuery太多次之外，你所看到的问题是第一个jQuery被加载，然后你找到了绑定到jQuery实例的Flot。一旦jQuery的下一个源实例发生，该关联就会消失。
请花些时间确保您在源代码脚本的开头一次获取jQuery，然后获取依赖于jQuery的所有内容。
