vue实现前端简易版模糊查询

在实际工作中，我们会遇到很多的模糊查询以及查询功能，今天做个记录，用vue实现简易版的模糊查询

<template>
  <div>
    <van-search v-model="value" @input="moduleChange" placeholder="请输入搜索关键词" />
    <div>
      <ul>
        <li v-for="(item,index) in list" :key="index">
          <span :style="{color:item.color?'red':''}">{{item.name}}</span>
        </li>
      </ul>
    </div>
  </div>
</template>

<script lang="ts">
import { cloneDeep } from "lodash";
import { Component, Vue } from "vue-property-decorator";
@Component
export default class Menu extends Vue {
  public value = "";
  public arr: { name: string; id: number; color?: boolean | undefined }[] = [
    {
      name: "张三",
      id: 1,
      color: false,
    },
    {
      name: "李四",
      id: 2,
      color: false,
    },
    {
      name: "测试",
      id: 2,
      color: false,
    },
  ];
  public list = cloneDeep(this.arr);

  public moduleChange(val: string) {
    const newArr = cloneDeep(this.arr);
    let reg = new RegExp(val);
    newArr.map((i) => {
      i.color = i.name.match(reg) && this.value ? true : false;
    });
    const searArr = newArr.find((el: any) => val === el.name);
    this.list = searArr ? [searArr] : newArr;
  }
}
</script>

<style scoped>
</style>
