There is an example of how to use JQuery flowchart in Angular programs here : https://github.com/nephilimboy/Angular_FlowChartJS .
(这里有一个如何在Angular程序中使用JQuery流程图的示例: https : //github.com/nephilimboy/Angular_FlowChartJS 。)
What I am trying to do is adding click events to the selected operator in the chart.(我正在尝试将点击事件添加到图表中的所选操作符。)
These are related codes of the flowchart:

When I select operators on the screen, the border color will change and also when hovering it the border becomes yellow.
(当我在屏幕上选择运算符时,边框颜色将更改,并且将鼠标悬停时边框也会变为黄色。)
But I don't know how to add click events to them to open a form when I click(select) them?(但是我不知道如何在单击(选择)它们时向它们添加单击事件以打开表单?)
