javascript - Axios 响应数据未加载到 Laravel 中的 Vue 组件上

Question

伙计们希望你们一切都好!我在将数据从 axios 响应传递到数据属性时遇到了一点问题。从数据库中获取的数据在获取后显示在控制台上，但是当我想在组件上显示它时，它显示一个空数组。提前致谢

Vue 组件脚本:

<script>
    import axios from 'axios';
    export default {
         data(){
                return {
                        Templates:[],
                        loading:true
                    }
        },
        async mounted() {
            await axios.post('/getTemplates')
                .then(response =>this.Templates =response.data )
                .catch(error => console.log(error.message))
                console.log(this.Templates)
        }

    }

</script>

我在组件上用 {{Templates}} 调用了数据属性:

<article class="overflow-hidden rounded-lg shadow-lg max-w-lg">
  <a href="#">
  </a>
      {{Templates}}
  <header class="flex items-center justify-between leading-tight p-2 md:p-4">
      <h1 class="text-lg">
          <a class="no-underline text-black" href="#">
          </a>
      </h1>
      <p class="text-grey-darker text-sm">
          Text
      </p>
  </header>
  <footer class="relative flex items-center justify-between leading-none p-2 md:p-4">
      <a class="flex items-center no-underline hover:underline text-black" href="#">

看起来 ES6 语法有点偏离，将 {} 大括号添加到您的 .then() 中，例如:

<script>
    import axios from 'axios';
    export default {
         data(){
                return {
                        Templates:[],
                        loading:true
                    }
        },
        async mounted() {
            await axios.post('/getTemplates')
                .then(response => { this.Templates = response.data })
                .catch(error => { console.log(error.message) })
                console.log(this.Templates)
        }

    }

</script>
