python - Flask 渲染 svg 文件，没有交互性

我的 Flask 应用程序有一个创建 .svg 文件(使用 pygal)并在模板中渲染的路线。在应用程序中，没有交互功能，但是，如果我从文件浏览器打开相同的 .svg 文件，我会获得我想要的完整交互功能，例如悬停标签等。有关如何获得交互的任何想法悬停在我的路线上吗？

{% extends "base.html" %}
{% block content %}
<div class="container">
<h2 style="text-align:center;">Matrix of Concern for {{ company.companyname }}</H2>
<div class="container-fluid">
    <div class="row-fluid">
        <img src="{{plot|safe}}" alt="Image did not Load">
    </div>
</div>
</div>
{% endblock %}

这是传递给模板的绘图变量

最佳答案

当您将 SVG 作为图像加载时，在本例中是通过 <img>标记它不是交互式的。这是一般规则，并非特定于 Flask。

图像中的 SVG 具有与光栅图像相同的功能，因此可以在相同的情况下使用它们，而无需特别考虑其安全和隐私影响。

关于python - Flask 渲染 svg 文件，没有交互性，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/47688964/
