Vue.js 和 Laravel 沒有使用 axios 刷新頁面

Question

大家好，我是 vue.js 的新手，我很困惑是否可以使用嵌入在 Blade.php 中的組件在不刷新頁面的情況下重新加載數據表（服務器端渲染）？

這是我的代碼。 所有這些組件都附加在一個blade.php 文件中。

Department.vue 組件（用於添加）

    <template>
      <div class="container">
        <div class="row justify-content-center">
          <div class="col-md-8">
            <div class="card">
              <div class="card-header">Add Department / Section</div>
              <div class="card-body">
                <form @submit.prevent="addData()">

                <div class="form-group">
                  <label class="form-control-label" for="name">Department</label>
                  <input type="text" class="form-control" v-model="department">
                  <div v-if="errors.department" :class="['invalid-feedback']">{{ errors.department[0] }}</div>
                </div>

                <div class="form-group">
                  <label class="form-control-label" for="name">Section</label>
                  <input type="text" class="form-control" v-model="section" v-bind:class="{'is-invalid': validate && attemptSubmit && missingName }">
                  <div v-if="errors.section" :class="['invalid-feedback']">{{ errors.section[0] }}</div>
                </div>

                <button type="submit" class="btn btn-primary btn-block">Submit</button>
                <button class="btn btn-primary btn-block">Edit</button>
                </form>
                <strong>Output:</strong>
                <pre>
                {{output}}
                </pre>
              </div>
            </div>
          </div>
        </div>
      </div>
    </template>

<script>
  export default {
    mounted() {
      axios.get('/api/departments')
      .then(response => this.rows = response.data)
      .catch(error => console.log(error))
        },
    data() {
      return {
        department: '',
        section: '',
        output: '',

        validate: false,

    },

        this.attemptSubmit = true;
        this.validate = true;
        this.errors = [];
        if (this.errors) event.preventDefault();

        axios
        .post('/api/department', {
                    department: this.department,
                    section: this.section
        })
        .then(response => {
          this.validate = false;
          this.department = '';
          this.section = '';
          this.errors = '';
          this.output = response.data;
        })
        .catch(error => this.errors = error.response.data.errors)
      },
      deleteData(id) {
        if(confirm('Are you sure?')) {
          axios
          .delete(`/api/department/${id}`)
          .then(response => {this.output = response.data;})
          .catch(error => console.log(error))
        }
      }
    }
  }
</script>

Project.vue 組件（數據表）

如果你想使用 Laravel 路由，那么當你改變路由時它會刷新。 創建 SPA 的方法很少。

1. 使用單獨的 vuejs 項目
2. 您可以使用https://inertiajs.com/
3. 您可以使用 laravel livewire。 火線

我更喜歡在你的情況下使用inertiajs/livewire，它可以很容易地與laravel和vuejs集成。
