您可以使用JavaScript来实现模糊搜索的功能,以下是一个简单的示例代码:
HTML部分:- <select id="select">
- <option value="1">Apple</option>
- <option value="2">Banana</option>
- <option value="3">Cherry</option>
- <option value="4">Orange</option>
- </select>
复制代码 JavaScript部分:- document.getElementById('select').addEventListener('input', function() {
- var input, filter, option, i;
- input = this.value;
- filter = input.toUpperCase();
- options = this.getElementsByTagName('option');
- for (i = 0; i < options.length; i++) {
- if (options[i].innerHTML.toUpperCase().indexOf(filter) > -1) {
- options[i].style.display = '';
- } else {
- options[i].style.display = 'none';
- }
- }
- });
复制代码 以上代码会监听select框的input事件,当用户输入内容时,会根据用户输入的内容来过滤选项。只有当某个选项的内容包含了用户输入的内容时,该选项才会显示出来,否则会被隐藏。这样就实现了模糊搜索的功能。
扩展:js实现模糊查询
今天为大家分享的是使用js实现模糊查询:
首先写出html- <div class="search">
- <input type="text" class="inp">
- <div class="but">搜索</div>
- </div>
- <div class="list"></div>
复制代码 再写css- * {
- padding: 0;
- margin: 0;
- }
- .search {
- width: 96%;
- margin-left: 2%;
- height: 60px;
- display: flex;
- align-items: center;
- justify-content: center;
- }
- .search input {
- width: 60%;
- height: 20px;
- border: 1px #eeeeee solid;
- padding: 5px;
- border-top-left-radius: 20px;
- border-bottom-left-radius: 20px;
- }
- .search div {
- width: 20%;
- height: 32px;
- text-align: center;
- line-height: 32px;
- background-color: #eeeeee;
- border-top-right-radius: 20px;
- border-bottom-right-radius: 20px;
- }
- .list {
- width: 96%;
- margin-left: 2%;
- }
- .list div {
- width: 100%;
- height: 40px;
- display: flex;
- justify-content: space-around;
- }
- .list span {
- display: block;
- width: 20%;
- line-height: 40px;
- text-align: center;
- }
复制代码 现在结构样式都有的就该写数据了- let arr = [{
- name: "吴小糖",
- addres: "河南",
- base: 410725,
- num: 9999
- }, {
- name: "吴三",
- addres: "浙江",
- base: 102419,
- num: 10000
- }, {
- name: "吴磊",
- addres: "北京",
- base: 314345,
- num: 5555
- }, {
- name: "吴谨言",
- addres: "湖南",
- base: 341026,
- num: 7888
- }, {
- name: "吴爽",
- addres: "河南",
- base: 410756,
- num: 6666
- }, {
- name: "吴宣仪",
- addres: "海南",
- base: 243187,
- num: 9999
- }]
复制代码
下一步就该js部分了- let but = document.getElementsByClassName("but")[0];
- let inp = document.getElementsByClassName("inp")[0];
- sorts(arr);
- but.onclick = function() {
- let data = [];
- for (let i = 0; i < arr.length; i++) {
- for (let k in arr[i]) {
- if (String(arr[i][k]).indexOf(inp.value) > -1) {
- data.push(arr[i]);
- break;
- }
- }
- }
- sorts(data);
- }
- function sorts(a) {
- let str = "";
- for (let i = 0; i < a.length; i++) {
- str += `<div>
- <span>${a[i].name}</span>
- <span>${a[i].base}</span>
- <span>${a[i].num}</span>
- <span>${a[i].addres}</span>
- </div>`
- }
- document.getElementsByClassName("list")[0].innerHTML = str;
- }
复制代码 这样就制作完成了,整体代码如下:- <!DOCTYPE html>
- <html>
- <head>
- <meta charset="utf-8" />
- <title></title>
- </head>
- <body>
- <!DOCTYPE html>
- <html>
- <head>
- <meta charset="utf-8">
- <meta name="viewport" content="width=device-width, initial-scale=1">
- <title></title>
- <style>
- * {
- padding: 0;
- margin: 0;
- }
- .search {
- width: 96%;
- margin-left: 2%;
- height: 60px;
- display: flex;
- align-items: center;
- justify-content: center;
- }
- .search input {
- width: 60%;
- height: 20px;
- border: 1px #eeeeee solid;
- padding: 5px;
- border-top-left-radius: 20px;
- border-bottom-left-radius: 20px;
- }
- .search div {
- width: 20%;
- height: 32px;
- text-align: center;
- line-height: 32px;
- background-color: #eeeeee;
- border-top-right-radius: 20px;
- border-bottom-right-radius: 20px;
- }
- .list {
- width: 96%;
- margin-left: 2%;
- }
- .list div {
- width: 100%;
- height: 40px;
- display: flex;
- justify-content: space-around;
- }
- .list span {
- display: block;
- width: 20%;
- line-height: 40px;
- text-align: center;
- }
- </style>
- </head>
- <body>
- <div class="search">
- <input type="text" class="inp">
- <div class="but">搜索</div>
- </div>
- <div class="list"></div>
- <script type="text/javascript">
- let arr = [{

- addres: "浙江",

- let but = document.getElementsByClassName("but")[0];
- let inp = document.getElementsByClassName("inp")[0];
- sorts(arr);
- but.onclick = function() {
- let data = [];
- for (let i = 0; i < arr.length; i++) {
- for (let k in arr[i]) {
- if (String(arr[i][k]).indexOf(inp.value) > -1) {
- data.push(arr[i]);
- break;
- }
- }
- }
- sorts(data);
- }
- function sorts(a) {
- let str = "";
- for (let i = 0; i < a.length; i++) {
- str += `<div>
- <span>${a[i].name}</span>
- <span>${a[i].base}</span>
- <span>${a[i].num}</span>
- <span>${a[i].addres}</span>
- </div>`
- }
- document.getElementsByClassName("list")[0].innerHTML = str;
- }
- </script>
- </body>
- </html>
- </body>
- </html>
