vue实现点击div外部触发事件的封装方法，注：基于element-ui

链接处：element-ui网址

实现代码

<template>
  <div class="app-container">
    <div v-clickoutside="clickOut" style="background: red">
      我是里面内容
    div>
    <div v-clickoutside="clickOut2" style="background: red">
      我是里面内容2
    div>
  div>
template>

<script>

import Clickoutside from 'element-ui/src/utils/clickoutside'
export default {
  directives: { Clickoutside },
  methods: {
    clickOut() {
      console.log('点击了外面内容')
    },
    clickOut2() {
      console.log('点击了外面内容2')
    }
  }
}

当然也给出clickoutside.js的源码 ( 只会复制粘贴的机器人！！！)

/**
 * v-clickoutside
 * @desc 点击元素外面才会触发的事件
 * @example
 * ```vue
 * 

 * ```
 */
export default {
  bind(el, binding, vnode) {
    nodeList.push(el);
    const id = seed++;
    el[ctx] = {
      id,
      documentHandler: createDocumentHandler(el, binding, vnode),
      methodName: binding.expression,
      bindingFn: binding.value
    };
  },

  update(el, binding, vnode) {
    el[ctx].documentHandler = createDocumentHandler(el, binding, vnode);
    el[ctx].methodName = binding.expression;
    el[ctx].bindingFn = binding.value;
  },

  unbind(el) {
    let len = nodeList.length;

    for (let i = 0; i < len; i++) {
      if (nodeList[i][ctx].id === el[ctx].id) {
        nodeList.splice(i, 1);
        break;
      }
    }
    delete el[ctx];
  }
};
