我有一把小提琴https://jsfiddle.net/91vLms06/1/

const CreateComponent = Vue.component('create', {
  props: ['user', 'otherProp'],
  template: '<div>User data: {{user}}; other prop: {{otherProp}}</div>'
});

const ListComponent = Vue.component('List', {
  template: '<div>Listing</div>'
});

const app = new Vue({
  el: '#app',
  router: new VueRouter(),
  created: function () {
    const self = this;
        // ajax request returning the user
    const userData = {'name': 'username'}

    self.$router.addRoutes([
      { path: '/create', name: 'create', component: CreateComponent, props: { user: userData }},
      { path: '/list', name: 'list', component: ListComponent },
      { path: '*', redirect: '/list'}
    ]);
    self.$router.push({name: 'create'}); // ok result: User data: { "name": "username" }; other prop:
    self.$router.push({name: 'list'}); // ok result: Listing

    // first attempt
    self.$router.push({name: 'create', props: {otherProp: {"a":"b"}}}) // not ok result: User data: { "name": "username" }; other prop:
    self.$router.push({name: 'list'}); // ok result: Listing

    // second attempt
    self.$router.push({name: 'create', params: {otherProp: {"a":"b"}}}) //not ok result: User data: { "name": "username" }; other prop:
  }
});

正如您首先看到的，我在初始化路由时将user传递给CreateComponent。
稍后我需要传递另一个属性otherProp，并且仍然保留user参数。当我尝试这样做时，我发送的对象没有传递到组件。
我怎样才能通过otherProp而仍然保留user？
otherProp的真实的目的是用它的数据填充表单，在列表部分我有一个对象，当我点击“编辑”按钮时，我想用列表中的数据填充表单。
