what is v-tree?

Tree menu based on Vue

en:A demo path: v-tree/src/components/vTreeDemo.Vue

zh:一个demo的路径: v-tree/src/components/vTreeDemo.Vue

Explain：

en:Functions already implemented： Single election、check box、Cascade selection、Yes/No pull-down、Callback function before clicking on node、
Click node function、Check/Cancel Check Box Events、Asynchronous loading node

zh:单选、复选、复选是/否级联选择（默认级联选中）、是否展示下拉虚线、点击节点回调函数，返回true 选中并触发选中事件，false相反，
节点选中事件，返回选中节点信息和上个选中节点信息，选中/取消选中复选框事件，将返回所有选中复选框数据
异步加载数据

Vue custom variables and function description. vue自定义变量和函数说明

Default single selection

:treeNode     type:json    default:[]

Standard JSON tree node,'name' attribute required. 标准json tree节点，name属性必填

:allOpen      type:boolean    default:false

Open/close all nodes
开启/关闭所有节点

:nodeTrigger     type:boolean     default:false

Click on a node to trigger a node event
点击节点是否触发节点事件

@call    type:Function     parameter:inside treeNode,You can change it and the page will be re-rendered.

Initialize callback function 初始化回调函数 参数为节点数据的深拷贝，你可以修改此数据，tree将会重新渲染

:beforeClick    type:Function     parameter:Current node information(参数：当前节点信息)

Trigger the callback function before clicking on the node,
return false Unable to trigger clickNode 击节点前触发回调函数，return false 无法触发clickNode事件

:clickNode    type:Function     parameter 1:Current node information,parameter 2:Last selected node information(上一个选中的节点信息)

click node callback function 点击节点 回调函数

:hiddenLine    type:Boolean     default: false

Hide hidden lines 是否隐藏 虚线

:checkBox    type:boolean     default:false

Open/close the check box 开启/关闭复选框

:checkBoxType    type:boolean     default:true

Open/close Cascade Selection 开启/关闭级联选中

@checkBoxCall    type:Function     parameter:All selected node sets(所有选中的节点集合)

Check/uncheck check box callback function 选中/取消选中复选框回调函数

:async    type:boolean     default:false

Open/close async loading 是否开启异步 默认关闭

:asyncCall    type:Function     parameter 1:Current node information,parameter 2:callback function,Receive an array parameter  
Example:

asyncCall(data, call) {    //data:Current node information
        setTimeout(function () {
          let hm = '' + (new Date()).getTime();
          let addNode = [
            {id: hm, name: "children node" + hm.substr(hm.length - 4, hm.length)},
          ];
          call(addNode);  //callback function
        }, 800);
      }

async loading callback function 异步回调函数function(data,call)，data:current node， call 回调执行，接收一个数组参数

A complete example：

    <Tree
        :treeNode="treeNode"
        :allOpen="allOpen"
        :nodeTrigger="nodeTrigger"
        :checkBox="checkBox"
        :beforeClick="beforeClick"
        :checkBoxType="checkBoxType"
        :clickNode="clickNode"
        :hiddenLine="hiddenLine"
        @checkBoxCall="asyncCheckBoxCall"
        @call='callAsync'
        :async="async"
        :asyncCall="asyncCall"
    />
