1、问题背景

系统利用zTree插件生成下拉复选树，点击文字勾选复选框

2、实现源码

		$(document).ready(function(){
			//初始化树
			zTree = $.fn.zTree.init($("#treeSelect"), setting, datas);
		});
	
		//设置
		var setting = {
			check: {
				enable: true
			},
			data: {
				simpleData: {
					enable: true
				}
			},
			callback: { 
			 	onClick: function (e, treeId, treeNode, clickFlag) { 
			 		zTree.checkNode(treeNode, !treeNode.checked, true); 
			 	} 
			},
    	}, zTree;

		//数据
		var datas =[
			{ id:1, pId:0, name:"树", open:true},
			{ id:11, pId:1, name:"松树", open:true},
			{ id:12, pId:1, name:"樟树", open:true},
			{ id:2, pId:0, name:"花", checked:true, open:true},
			{ id:21, pId:2, name:"梅花"},
			{ id:22, pId:2, name:"桃花", open:true}
		];
