一、Ajax
1 Ajax 介绍
1.1 Ajax 概述
1.2 同步异步
2 原生 Ajax
<body>
<input type="button" value="获取数据" onclick="getData()">
<div id="div1"></div></body>
<script>
function getData(){
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open('GET','http://yapi.smart-xwork.cn/mock/169327/emp/list');
xmlHttpRequest.send();
xmlHttpRequest.onreadystatechange = function(){
if(xmlHttpRequest.readyState == 4 && xmlHttpRequest.status == 200){
document.getElementById('div1').innerHTML = xmlHttpRequest.responseText;
}
}
}
</script>
3 Axios
3.1 Axios 的基本使用
<script src="js/axios-0.18.0.js"></script>
axios({
method: "get",
url: "http://yapi.smart-xwork.cn/mock/169327/emp/list"
}).then((result) => {
console.log(result.data);
});
axios({
method: "post",
url: "http://yapi.smart-xwork.cn/mock/169327/emp/deleteById",
data: "id=1"
}).then((result) => {
console.log(result.data);
});
3.2 请求方法的别名
axios.get("http://yapi.smart-xwork.cn/mock/169327/emp/list").then((result) => {
console.log(result.data);
});
axios.post("http://yapi.smart-xwork.cn/mock/169327/emp/deleteById","id=1").then((result) => {
console.log(result.data);
