是否有事件侦听器可检测点/SVG图形上的鼠标单击? [英] Are there event listeners to detect mouse clicks on dot/SVG graph?

问题描述

我正在玩生成点文件，然后将它们转换为具有很多节点的SVG图.

I am playing with generating dot files and then turned them into SVG graphs with a lot of nodes.

我的问题是，是否存在事件侦听器来检测在点/SVG图形节点上的鼠标单击?

My question is that are there event listeners to detect mouse clicks on dot/SVG graph nodes?

例如，右键单击SVG图中的一个节点，我做某事(也许从该节点获取相关信息，然后再做某事)，

For example, right click on a node in the SVG graph, I do something(maybe get the related information from the node and then do something),

然后如何生成点文件或SVG文件来实现此目的?

Then how to generate dot file or SVG file to achieve this?

推荐答案

有几种创建交互式SVG图的方法:

There are several ways to create an interactive SVG graph:

• 使用SMIL(svg的扩展名)(示例教程 http://apike.ca/prog_svg_smil.html)
• JavaScript( Raphael 库非常好)
• CSS动画

• Use SMIL, an extension to svg (Example tutorial http://apike.ca/prog_svg_smil.html)
• Javascript (the Raphael library is excellent)
• CSS animations

无论如何，您都必须在支持任何这些技术(浏览器)的客户端中显示svg图，并且除了graphviz创建的svg输出之外，还必须对其进行编码.

In any case, you'll have to display the svg graphs in a client which supports any of those technologies (browser), and you will have to code it in addition to the svg output graphviz creates.
