javascript - Vue.js 的引导表/分页中的数据问题

Question

我的表目前不显示我从 rest api (itunes) 返回的数据，它也不分页。在控制台中我得到:

<table result="[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]" id="my-table" aria-busy="false" aria-colcount="2" class="table b-table table-sm"><!----><!----><thead role="rowgroup" class=""><!----><tr role="row"><th role="columnheader" scope="col" aria-colindex="1" class="">Artist</th><th role="columnheader" scope="col" aria-colindex="2" class="">Song title</th></tr></thead><!----><tbody role="rowgroup" class=""><!----><!----><!----></tbody></table>

我的组件代码是:

<template>
  <div class="container search">
    <div class="row">
      <div class="col-md-8">

 <div class="jumbotron mt-5" style="clear:both">
      <h1 class="display-4">{{title}}</h1>
      <p class="lead">{{intro}}</p>
      <hr class="my-4">
      <p v-if="validated" :class="errorTextClass">Enter a valid search term</p>

      <button
        type="button"
        class="btn btn-primary btn-lg mb-3"
        v-on:click="refreshPage"
        v-if="result.length > 1"
      >
        <font-awesome-icon icon="redo"/> Start again
      </button>
      <input
        class="form-control form-control-lg mb-3"
        type="search"
        placeholder="Search"
        aria-label="Search"
        v-model="search"
        required
        autocomplete="off"
        id="search"
      >
  <div class="overflow-auto">

<b-pagination
      v-model="currentPage"
      :total-rows="rows"
      :per-page="perPage"

    <p class="mt-3">Current Page: {{ currentPage }}</p>

    <b-table

任何帮助都会很好，因为我不明白这可能发生在哪里我是 Vue 的新手，我认为我在表中调用了错误的变量或类似的东西..

将 result="..." 更改为 :result="..."。您需要绑定(bind)值(: 是v-bind: 的快捷方式)。
