jsvascript使用dhtmlXTreeObject的loadJSONObject绘制目录树

1，引入dhtmlXTreeObject的css和js文件

注意： js的引用顺序很关键！！！

2，创建一棵目录树

2.1，let tree = new dhtmlXTreeObject(id-dhtmltree-0, “100%”, “100%”, 0);

2.2，设置图片根目录（后续使用到的图片都是相对于该目录的）

tree.setImagePath("/common/dhtmlxTree/imgs/");

3，代码

            let tree = new dhtmlXTreeObject(`id-dhtmltree-${this.groupId}`, "100%", "100%", 0);tree.setImagePath("/common/dhtmlxTree/imgs/");//tree.enableCheckBoxes(1);let jsonobj = {id:0, item:[{id:1,text:"root",im0:"common/dhtmlxtree_icon.gif",im1:"common/dhtmlxtree_icon.gif",im2:"common/dhtmlxtree_icon.gif",item:[{id:2,text:"first"},{id:3, text:"middle", item:[{id:"31", text:"child"}]},{id:4,text:"last"}]}]}console.log(tree)tree.loadJSONObject(jsonobj, function(){console.log("load json to tree success!")});
