python - Flask 渲染 svg 文件，没有交互性

Question

我的烧瓶应用程序有一个创建 .svg 文件（使用 pygal）并在模板中呈现的路由。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，我将获得我想要的完整交互功能，例如悬停标签等。关于如何获得交互的任何想法悬停在我的路线上工作？

{% 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

当您将 SVG 作为图像加载时，在这种情况下，通过<img>标签它不是交互式的。这是一般规则，并非特定于烧瓶。

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

python - Flask 渲染 svg 文件，没有交互性
