我有一个Google图表HTML页面,每当我单独发动它时,它都会绘制出精美的图表。页面代码如下

现在,当我将内容放置在现有项目页面之间时,尤其是在现有项目页面之间时,将不会绘制图表,并且在chrome的控制台中遇到以下错误
VM410:7 Uncaught (in promise) TypeError: google.visualization.DataTable is not a constructor
at drawElement3Dashboard (eval at <anonymous> (jquery-1.7.2.js:614), <anonymous>:7:13)
我已经包括在内
<script type='text/javascript' src='https://www.gstatic.com/charts/loader.js'></script>
在我的项目中。
伙计,这可能是什么原因?
您可以将其添加到代码中吗。
drawDisplacementChart();
drawDistanceChart();
