async和await
一，基本使用
其实就是之前学过的异步函数，异步编程在函数前写一个ansyc，就转化为异步函数，返回的是一个promise对象，于是就可以使用await关键字，可以把异步函数写成同步函数的形式，极大地提高代码的可读性。
原本的：
axios.get('adata',{
params:{
id:123,
name:'zhangsan'
}
}).then(function(ret){
console.log(ret)
})
现在：
//利用ansyc和await编写
async function queryData(){
var ret=await axios.get('adata',{
params:{
id:12,
name:'lisi'
}
})
//直接利用axios.get('地址')，通过await取得服务器的响应，并赋值给ret
console.log(ret)
//因为响应拦截器已经处理成ret.data了，所以这里会直接得到服务器响应的信息
}
queryData()
整体代码：
-------------------------------------------------------------------------------
用try {} catch() {},配合async 和await ，await后面可以接对应的方法（该方法必须返回一个promise对象，方法必须包含async和await）
async doSave () {
let param = this.$props.currentLog // 当前待办数据
let config = {
'pivCompetenceAppraiseInstanceId': this.currentMemberInfodata.pivCompetenceAppraiseInstanceId,
'pivCompetenceScoreConfirmDetailList': this.tableData3,
'pivSchemeCompetenceId': param ? param.pivSchemeCompetenceId : this.currentIndexRowData.pivSchemeCompetenceId,
'pivSchemeCompetenceTemplateId': param ? param.pivSchemeCompetenceTemplateId : this.currentIndexRowData.pivSchemeCompetenceTemplateId
}
try {
let res = await Api.getEdit(config)
this.$message.success(res.data)
await this.editRow(this.currentRowdata) // 等刷新当前数据后再赋值,editRow 方法必须加上async 和await
// 保留之前输入的备注，不被清空
this.pivAnonymousAccountRows.map(v1 => {
this.tableDataRowData.map(v2 => {
if (v1.id === v2.id) {
v1.remark = v2.remark
}
})
})
} catch (err) {
this.$message.error(err.message)

this.templateEvaluationMode = row.templateEvaluationMode
