vue给对象动态添加属性和值的实例

let that = this;  
let params = {
 "type":that.addQueTable.type,
 "discussTitle":that.addQueTable.discussTitle, 
};
// 区分普通题库还是模考题库
let addQuestionApi = '';
if(that.questionTypes == 0){
  // 动态设置vue对象参数
  Vue.set(params,'charpterId',that.charpterIds)
 addQuestionApi = api.saveBgInfoQuestion;
 }else{
 Vue.set(params,'mockexamSectionId',that.charpterIds);
 addQuestionApi = api.saveMockQuestion;
 }
that.$refs.addQueTable.validate((valid) => {
 if(valid){
 that.$axios({
 url:addQuestionApi,
 method: "post",
 data: qs.stringify(params),
 headers: {
 "Content-Type": "application/x-www-form-urlencoded"
 }
}).....

// 1、页面导入Vuejs文件库
import Vue from 'vue'
// 2、Vue.set即可，按照上面方式
