Method to obtain ZTREE selected nodes in the background_javascript skills

The example in this article describes the method of obtaining ZTREE selected nodes in the background. Share it with everyone for your reference. The specific implementation method is as follows:

function count() {
    var zTree = $.fn.zTree.getZTreeObj("classpurview");
    checkCount = zTree.getCheckedNodes(true);

    var classpurview = "";
    for(var i=0;i<checkCount.length;i++) {
   classpurview += "," + checkCount[i].id
    }
    alert(classpurview);
}

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