借助baidu的jsonp接口,做一个自己的候选词组件
2019-12-03

先观察

对接口进行提炼:https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=关键词&cb=回调函数

简单测试一下:

<!DOCTYPE html><html><head> <meta charset="utf-8" /> <meta http-equiv="X-UA-Compatible" content="IE=edge"> <title>百度候选词</title> <meta name="viewport" content="width=device-width, initial-scale=1"> <script> let test = (data) => { console.log(data); } </script> <script src="https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=dn&cb=test"></script></head><body> <!-- https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=关键词&cb=回调函数 --></body></html>

效果:

尝试把内容放入一个ul内:

<!DOCTYPE html><html><head> <meta charset="utf-8" /> <title>百度候选词</title></head><body> <ul id="myul"></ul> <script> // 为什么放ul的下面,可以看这篇文章:https://www.cnblogs.com/dotnetcrazy/p/10106976.html let test = (json) => { let ulobj = document.getElementById("myul"); json.s.forEach(item => { let liobj = document.createElement("li"); liobj.innerHTML = item; ulobj.appendChild(liobj); }); } // https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=关键词&cb=回调函数 </script> <script src="https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=dn&cb=test"></script></body></html>

效果:

根据input输入动态获取

<!DOCTYPE html><html><head> <meta charset="utf-8" /> <title>百度候选词</title> <script> // https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=关键词&cb=回调函数 let show_ul = (json) => { let ul_obj = document.getElementById("myul"); ul_obj.innerHTML = ""; // 清空现在的ul console.log(json.s); json.s.forEach(item => { let li_obj = document.createElement("li"); li_obj.innerHTML = item; ul_obj.appendChild(li_obj); }); } window.onload = () => { let input_obj = document.getElementById("myinput"); input_obj.oninput = () => { // 用script加载的方式,只会执行一次,不满足我们的需求,so ==> 动态创建 let script_obj = document.createElement("script"); script_obj.src = `https://sp0.baidu.com/5a1Fazu8AA54nxGko9WTAnF6hhy/su?wd=${encodeURIComponent(input_obj.value)}&cb=show_ul` document.body.appendChild(script_obj); //添加到body里面 } } </script></head><body> <input type="text" id="myinput" /> <ul id="myul"></ul></body></html>

效果:

线上测试

可行,下面就美化,然后放入自己项目的input中了
