Vue-Element
Ajax
原生Ajax
1. 创建XMLHttpRequest
var xmlHttpRequest = new XMLHttpRequest();2. 发送异步请求
xmlHttpRequest.open('GET','http://yapi.smart-xwork.cn/mock/169327/emp/list');
xmlHttpRequest.send();//发送请求3. 获取服务响应数据
xmlHttpRequest.onreadystatechange = function(){
if(xmlHttpRequest.readyState == 4 && xmlHttpRequest.status == 200){
document.getElementById('div1').innerHTML = xmlHttpRequest.responseText;
}
}Axios
引入Axios的js文件
<script src="js/axios-0.18.0.js"></script>通过axios发送异步请求-get
// axios({
// method: "get",
// url: "http://yapi.smart-xwork.cn/mock/169327/emp/list"
// }).then(result => {
// console.log(result.data);
// })
axios.get("http://yapi.smart-xwork.cn/mock/169327/emp/list").then(result => {
console.log(result.data);
})通过axios发送异步请求-post
// axios({
// method: "post",
// url: "http://yapi.smart-xwork.cn/mock/169327/emp/deleteById",
// data: "id=1"
// }).then(result => {
// console.log(result.data);
// })

开发流程
Element
快速入门
安装ElementUI组件库(在当前工程的目录下)，在命令行执行指令：
npm install [email protected]
引入ElementUl组件库
import ElementUI from 'element-ui';
import 'element-ui/lib/theme-chalk/index.css';
Vue.use(ElementUI);访问官网，复制组件代码，调整
<!-- button按钮 -->
<el-row>
<el-button>默认按钮</el-button>
<el-button type="primary">主要按钮</el-button>
<el-button type="success">成功按钮</el-button>
<el-button type="info">信息按钮</el-button>

表格
Table 表格:用于展示多条结构类似的数据，可对数据进行排序、筛选、对比或其他自定义操作。
<el-table :data="tableData" border style="width: 100%">
<el-table-column prop="date" label="日期" width="180"> </el-table-column>
<el-table-column prop="name" label="姓名" width="180"> </el-table-column>
<el-table-column prop="address" label="地址"> </el-table-column>
</el-table>分页
Pagination 分页:当数据量过多时，使用分页分解数据。
<el-pagination background layout="total,sizes, prev, pager, next, jumper"
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:total="1000"></el-pagination>对话框
Dialog 对话框:在保留当前页面状态的情况下，告知用户并承载相关操作。
<el-button type="text" @click="dialogTableVisible = true">打开嵌套表格的 Dialog</el-button>
<el-dialog title="收货地址" :visible.sync="dialogTableVisible">
<el-table :data="gridData">
<el-table-column property="date" label="日期" width="150"></el-table-column>
<el-table-column property="name" label="姓名" width="200"></el-table-column>
<el-table-column property="address" label="地址"></el-table-column>
</el-table>
</el-dialog>表单
Form 表单:由输入框、选择器、单选框、多选框等控件组成，用以收集、校验、提交数据
<el-button type="text" @click="dialogFormVisible = true">打开嵌套Form的 Dialog</el-button>
<el-dialog title="Form表单" :visible.sync="dialogFormVisible">
