【导语】:一个纯 JS 的轻量级主动补全工具库。
简介
autoComplete.js 是一个简略的、轻量级的、无其余依赖的 JS 主动补全工具库,它疾速、功能丰富,并且能够与各种我的项目或零碎无缝集成。它具备以下性能个性:
- 纯 JS 语言编写
- 无其余内部依赖
- 简略易用
- 轻量
- 疾速
- 功能丰富
- 高度可定制

- HTML 本地加载
<`script src="./autoComplete.js"></script>
- HTML 本地 ES6 模块加载
<script src="./index.js" type="module"></script>
- ES6 导入
import autoComplete from "./autoComplete";
- npm 装置
npm i @tarekraafat/autocomplete.js
- yarn 装置
yarn add @tarekraafat/autocomplete.js
- Node 援用
const autoComplete = require("@tarekraafat/autocomplete.js/dist/js/autoComplete");
应用
- 将 CSS 放到 HEAD 标签内
<link rel="stylesheet" href="./css/autoComplete.css">
OR
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/@tarekraafat/autocomplete.js@8.3.2/dist/css/autoComplete.min.css">
- 将默认 id 值 autoComplete 调配给 input 元素或任何自定义的 id/class,并在 selector 中选中自定义的元素。参考第 4 步
<input id="autoComplete" tabindex="1"> <!-- Default "id" value = "autoComplete"> -->
- 将 autoComplete.js 或集体的 js 文件放到 BODY 标签内
<script src="./js/autoComplete.min.js"></script>
<script src="./js/index.js"></script>
OR
<script src="https://cdn.jsdelivr.net/npm/@tarekraafat/autocomplete.js@8.3.2/dist/js/autoComplete.min.js"></script>
<script src="./js/index.js"></script>
- 创立 autoComplete 引擎示例,并增加配置
new autoComplete({data: { // Data src [Array, Function, Async] | (REQUIRED)
src: async () => {
// API key token
const token = "this_is_the_API_token_number";
// User search query
const query = document.querySelector("#autoComplete").value;
// Fetch External Data Source
const source = await fetch(`https://www.food2fork.com/api/search?key=${token}&q=${query}`);
// Format data into JSON
const data = await source.json();
// Return Fetched data
return data.recipes;
},
key: ["title"],
cache: false
},
query: {// Query Interceptor | (Optional)
manipulate: (query) => {return query.replace("pizza", "burger");
}
},
sort: (a, b) => {// Sort rendered results ascendingly | (Optional)
if (a.match < b.match) return -1;
if (a.match > b.match) return 1;
return 0;
},
placeHolder: "Food & Drinks...", // Place Holder text | (Optional)
selector: "#autoComplete", // Input field selector | (Optional)
observer: true, // Input field observer | (Optional)
threshold: 3, // Min. Chars length to start Engine | (Optional)
debounce: 300, // Post duration for engine to start | (Optional)
searchEngine: "strict", // Search Engine type/mode | (Optional)
resultsList: {// Rendered results list object | (Optional)
container: source => {source.setAttribute("id", "food_list");
},
destination: "#autoComplete",
position: "afterend",
element: "ul"
},
maxResults: 5, // Max. number of rendered results | (Optional)
highlight: true, // Highlight matching results | (Optional)
resultItem: {// Rendered result item | (Optional)
content: (data, source) => {source.innerHTML = data.match;},
element: "li"
},
noResults: (dataFeedback, generateList) => {
// Generate autoComplete List
generateList(autoCompleteJS, dataFeedback, dataFeedback.results);
// No Results List Item
const result = document.createElement("li");
result.setAttribute("class", "no_result");
result.setAttribute("tabindex", "1");
result.innerHTML = `<span style="display: flex; align-items: center; font-weight: 100; color: rgba(0,0,0,.2);">Found No Results for "${dataFeedback.query}"</span>`;
document.querySelector(`#${autoCompleteJS.resultsList.idName}`).appendChild(result);
},
onSelection: feedback => {// Action script onSelection event | (Optional)
console.log(feedback.selection.value.image_url);
}
});
- 属性配置信息
-
data:示意数据源,键,缓存和后果集,值为
- 1-src:字符串或对象数组;或者返回字符串或对象数组的函数,Function() => {}
- 2-key:如果 src 是对象,key 是必须的,用于解析对象
- 3-Cache:静态数据设置为 true,动态数据设置为 false
- 4-Result:list,字符串或对象数据
-
query:查问拦截器
- 只有一个办法 manipulate,参数是查问的对象,拦挡查问对象做个性化开发
-
sort:对后果集排序
- 函数,对后果集排序,返回 1,-1,0
-
selector:输入框选择器,抉择需进行主动补全的元素:
- id 或 class 字符串
- 或者一个查问返回 html 元素的函数
- 以上只是列出了比拟重要的几个配置属性,具体的阐明参考官网
- 生命周期函数
- init:初始化 autoComplete 引擎后触发
- fetch:获取数据实现后触发
- input:用户每次输出时触发
- results:搜寻实现准备就绪后触发
- rendered:渲染后果列表后触发
- navigation:在每个 resultList 后果交互上触发
- unInit:初始化 autoComplete 引擎前触发
- 例子
