Vue公司2 - 在一个模板正常工作的道具，而不是在另一个

Question

正常工作，我有以下Vue公司的主要情况：

let App = new Vue({ 

    el: '#app-container', 

    data: { 
     countries: [] 
    }, 

    created() { 
     this.getCountries() 
    }, 

    methods: { 

     getCountries() { 

      let self = this; 

      axios.get('/admin/countries') 
       .then(function (response) { 

        self.countries = response.data; 

       }) 
       .catch(function (error) { 
        console.log(error); 
       }); 

     }, 

     filterCountries(event) { 

      let name = event.target.value; 

      let self = this; 

      if(name.length > 2) { 

       axios.get('/country/search', { 
        params: { 
         name: name 
        } 
       }) 
       .then(function (response) { 
        self.countries = response.data; 
       }) 
       .catch(function (error) { 
        console.log(error); 
       }); 

      } 

      if((event.keyCode === 8 && name.length == 2) || !name.length){ 
       this.getCountries(); 
      } 
     }, 

     updateCountry(event) { 

      let parent = event.target.closest('.parent'); 

      let countryName = parent.getElementsByClassName('country-name')[0].value; 

      let countryOrder = parent.getElementsByClassName('country-order')[0].value; 

      axios.post('/country/insert', { 
       countryName: countryName, 
       countryOrder: countryOrder 
      }) 
      .then(function (response) { 
       console.log(response); 
      }) 
      .catch(function (error) { 
       console.log(error); 
      }); 


     } 
    } 

}) 

我有这个模板这是工作：

Vue.component('country-list', { 
    template: ` 
    <tbody> 
     <tr is="country" v-for="country in countries.data"> 
      <td> 
       <input 
        type="text" 
        name="name" 
        class="form-control country-name" 
        :value="country.name" 
       > 
      </td> 
      <td>{{country.show? 'Yes' : 'No'}}</td> 
      <td> 
       <input 
        type="text" 
        name="order" 
        class="form-control country-order" 
        :value="country.order" 
       > 
      </td> 
      <td> 
       <button class="btn btn-primary">{{ country.show ? "Hide" : "Show" }}</button> 
       <button class="btn btn-success" 
        @click="updateCountry" 
        :data-id="country.id">Update</button> 
      </td> 
     </tr> 
    </tbody> 
    `, 

    props: ['countries'], 

    methods: { 

     updateCountry(event) { 

      let countryID = event.target.dataset.id; 

      let parent = event.target.closest('.parent'); 

      let countryName = parent.getElementsByClassName('country-name')[0].value; 

      let countryOrder = parent.getElementsByClassName('country-order')[0].value; 

      axios.post('/country/insert', { 
       id: countryID, 
       name: countryName, 
       order: countryOrder 
      }) 
      .then(function (response) { 
       console.log(response); 
      }) 
      .catch(function (error) { 
       console.log(error); 
      }); 

     } 

    } 
}); 

Vue.component('country', { 
    template: `<tr class=parent><slot></slot></tr>` 
}); 

我试图使用相同的道具（国家），但我没有得到任何东西（在这种情况下，我有以下错误：

vendor.js:753 [Vue warn]: Error in render function: "TypeError: Cannot read property 'current_page' of undefined" 

found in 

---> <PaginationList> 
     <Root> 

）：

Vue.component('pagination-list', { 

    template: ` 
     <tfoot> 
      <tr> 
       <td>{{countries.current_page}}</td> 
      </tr> 
     </tfoot> 
    `, 

    props: ['countries'] 
}); 

HTML代码中使用的模板：

<table class="table table-striped table-hover"> 

    <thead> 

     <tr> 
      <td> 
       <input 
        class="form-control" 
        type="text" 
        id="country-filter" 
        @keyup="filterCountries" 
        placeholder="Filter countries by name"> 
      </td> 
     </tr> 

     <tr> 

      <td>Country Name</td> 
      <td>Visible</td> 
      <td>Order</td> 
      <td>Actions</td> 

     </tr> 

    </thead> 

    <tbody is="country-list" :countries="countries"></tbody> 

    <tfoot is="pagination-list"></tfoot> 

</table> 

的console.log（self.countries）数据：

Object {…} 
current_page:1 
data:Array(20) 
from:1 
last_page:13 
next_page_url:"http://smuvajse.app/admin/countries?page=2"

你不及格通过您的模板道具：

<tfoot is="pagination-list"></tfoot> 

应该是：

<tfoot is="pagination-list" :countries="countries"></tfoot>
