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>

</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>
