How to get the selected node of zTree on the parent page_javascript skills

The example in this article describes the method of getting the zTree selected node on the parent page. Share it with everyone for your reference. The details are as follows:

Put zTree in an iframe:

zTreeObj = $("#treeDemo").zTree(setting, zNodes);

If you are on the current page, pass

var nodes = zTreeObj.getCheckedNodes(); 

That’s it

So how do you get the selected node of zTree when you click the button on the parent page?

Assume that the id and name of the iframe are aa (both id and name are set, compatibility issue)

window.frames['aa'].window.zTreeObj.getCheckedNodes();

That’s it

I hope this article will be helpful to everyone’s JavaScript programming design.
