SVG路径元素未触发JavaFX8 Web视图中的鼠标事件

SVG path element is not triggering mouse events in JavaFX8 webview

本文关键字：视图 鼠标 事件 Web JavaFX8 元素 路径 SVG      更新时间：2023-09-26

我有一个带有内联SVG的html页面。path元素上有一个事件处理程序。这在浏览器（Chrome/IE/FF）中非常有效，但当我在JAVAFX8的网络视图中尝试时。不会为path元素触发click事件。

这是示例代码。http://jsfiddle.net/YTWw9/4/


    $('path').click(function(event){
        $(event.target).attr('stroke', "yellow");
    });

I used different method using SVG and XML with database links and it is posted in my blogspot
