# 文本节点自定义

# 使用说明

  1. 初始化参数添加customText函数,返回的参数data为当前节点数据
  2. 通过在回调函数中拼接节点,并返回节点
  3. 添加的节点事件可以在节点的click回调事件中捕获,click事件的this代表当前点击的事件event
  4. 给每个节点添加一个class,并在事件中使用this.target.classList.contains('class'),判断当前点击的是否为某个节点,然后可以在对应的事件中执行某些操作,如增删改查等

# 注意

  1. 拼接的节点中,文本不能被其他dom包裹,如<span>data.label</span>,否则点击文本无法展开合并节点

# 示例

<div class="eletree13"></div>

<script>
var index = 0;
var el = eleTree({
    el: '.eletree13',
    url: '/eleTree/json/1.json?v=2.0.12',
