Vue路由器从vue路由器链接获取价值

Question

我的桌子上有清单。它具有一个编辑按钮，如果单击编辑按钮，它将转到另一个称为editTeacher的组件。我的问题是如何从表中获取数据并将其传输到editTeacher组件。我使用axios从路由获取数据。在laravel中是这样的

<a href="/editTeacher/{{$teacher->id}}" class="btn btn-info"><span class="glyphicon glyphicon-pencil"></a>。

我该如何在Vue中实现它？

这是我的代码段

<table id="myTable" class="table table-hover">
  <tbody>
   <tr>
    <th>ID</th>
    <th>Image</th>
    <th>First Name</th>
    <th>Last Name</th>
    <th>Gender</th>
    <th>Birthday</th>
    <th>Age</th>
    <th>Type</th>
    <th>Department</th>
    <th>Status</th>
    <th>Actions</th>
   </tr>
   <tr v-for="teacher in teachers" :key="teacher.id">
    <td>{{teacher.id}}</td>
    <td><img style=" border-radius: 50%;" :src="'img/'+teacher.image"  height="42" width="42"/></td>
    <td>{{teacher.firstname}}</td>
    <td>{{teacher.lastname}}</td>
    <td>{{teacher.gender}}</td>
    <td>{{teacher.birthday}}</td>
    <td>{{teacher.age}}</td>
    <td>{{teacher.type}}</td>
    <td>{{teacher.department_name}}</td>
    <td v-if="teacher.status == 1"><span  class="label label-success">Active</span></td>
    <td v-else><span  class="label label-danger">Inactive</span></td>
    <td><router-link to="/viewTeacher"> <i class="fa fa-edit"></i></router-link></td>
   </tr>
  </tbody>
</table>

路线

//Teachers
Route::get('/getTeachers','TeacherController@index');
Route::post('/addTeacher','TeacherController@store');
Route::put('/editTeacher/{id}','TeacherController@update');

app.js路线

{ path: '/viewTeacher', component: require('./components/editTeacher.vue').default },

Answer 1

请按照以下代码进行Vue js编辑方法。根据您的git repo。

app.js路线

{ path: '/viewTeacher/:id', component: require('./components/editTeacher.vue').default, name: viewTeacher},

Teachers.vue中的编辑按钮

<router-link :to="{name: 'viewTeacher', params: {id: teacher.id}}" class="btn btn-xs btn-default">Edit</router-link>

EditTeacher.vue组件

<template>
   <div class="row">
      <div class="col-xs-3">
          <div class="box">
              <div class="box-tools">
