便宜点的网站建设wordpress登录可见插件

码

const shuai = 'No'
'My Name Is ShuaiGe'.match(new RegExp(shuai, 'gi'));
//↑↑↑↑↑↑↑↑
//等同于
//↓↓↓↓↓↓↓↓
/No/gi.test('My Name Is ShuaiGe')

用作领域

• 搜索的字符动态改变，例如↓
• 模糊搜索
• 例：
  • 一个文本宽，输入文本模糊搜索用户

码

• 现有n条数据，文本框输入时模糊过滤

<template><inputtype="text"@input="inputEv"v-model="search"placeholder="输入用户昵称"/><h5 style="border-bottom: dashed 1px black" v-for="i in renderList">{{ i.name }}</h5>
</template>
<script setup>
import { ref } from "vue";// 假如这里有很多数据
const data = [{name: "abcsjddhfjkfkfedkfdjf",},{name: "dfefea",},{name: "fefefee",},{name: "dddwd",},{name: "dwdwd",},{name: "2233",},{name: "ewe34",},{name: "dwdw",},{name: "343dw",},{name: "2343w",},{name: "343ewd",},{name: "2344wd",},{name: "343edwd",},{name: "343wd",},{name: "e2432ew",},{name: "22ewd",},{name: "ewe243",},
];
const renderList = ref([]);
const search = ref("");/*** input事件触发*/
const inputEv = _ =>  renderList.value = filterArr(search.value, data)//开始调用过滤方法/*** 数据过滤器* @param {String} filterStr 过滤的字符串* @param {Array} arr 查询的数组* @returns Array 过滤返回的数组*/
const filterArr = (filterStr, arr) => {// 若传入空值，返回空数组if (filterStr === "") return [];const fliterData = [];arr.forEach((it) => {// 正则表达式 -> 相当于 -> /xxxx/.test(it.name) -> xxxx表示动态正则 ↓const reg = new RegExp(filterStr, "gi");const res = it.name.match(reg); //开始模糊搜索// 搜索到，push到fliterDataif (res !== null) fliterData.push(it);});// 最后返回过滤的数组return fliterData;
};
</script>
