用Vue编写抽象组件的方法

<script>
import {get, debounce, set} from 'loadsh';

export default {
  name: 'debounce',

  abstract: true, //标记为抽象组件

  render() {
    let vnode = this.$slots.default[0]; // 子组件的vnode
    if (vnode) {
      let event = get(vnode, `data.on.click`); // 子组件绑定的click事件
      if (typeof event === 'function') {
        set(vnode, `data.on.click`, debounce(event, 1000));
      }
    }
    return vnode;
  }
};
</script>

<debounce>
  <button @click="clickHandler">测试</button>
</debounce>

<script>
import {get, debounce, set} from '@/utils';

export default {
  name: 'debounce',

  abstract: true, //标记为抽象组件

  props: {
    events: String,
    wait: {
      type: Number,
      default: 0
    },
    options: {
      type: Object,
      default() {
        return {};
      }
    }
  },

  render() {
    let vnode = this.$slots.default[0]; // 子组件的vnode

    if (vnode && this.events) {
      let eventList = this.events.split(',');
      eventList.forEach(eventName => {
        let event = get(vnode, `data.on[${eventName}]`); // 子组件绑定的click事件
        if (typeof event === 'function') {
          /**
           * 加上debounce操作, 参数与 lodash 的debounce完全相同
           */
          set(vnode, `data.on[${eventName}]`, debounce(event, this.wait, this.options));
        }
      });
    }
    return vnode;
  }
};
</script>

<debounce events="click" :wait="250" :options="{maxWait: 1000}">
  <button @click="clickHandler">测试</button>
</debounce>

<debounce events="input" :wait="250" :options="{maxWait: 1000}">
  <input @input="inputandler" placeholder="输入关键字进行搜索" />
</debounce>
