handlebars #每个助手无法正确迭代

Question

我有一个如下所示的车把片段

<table class="table">
  <thead>
    <tr>
      <th scope="col">#</th>
      <th scope="col">Name</th>
      <th scope="col">Message</th>
      <th scope="col">Time</th>
    </tr>
  </thead>
  <tbody>
    {{#each result}}
    <tr>
      <th scope="row">{{@index}}</th>
      <td>{{this.name}}</td>
    </tr>
    {{/each}}
  </tbody>
</table>

结果是来自 mongodb 的数组，如下所示

[
  {
    _id: new ObjectId("651de76a44d50f1d9cfedede"),
    name: 'Lucy',
    message: 'I way',
    createdAt: 2023-10-04T22:30:02.377Z,
    updatedAt: 2023-10-04T22:30:02.377Z,
    __v: 0
  },
  {
    _id: new ObjectId("651de7eca2da2627f94ce3cb"),
    name: 'Tanya',
    message: 'I like chemical',
    createdAt: 2023-10-04T22:32:12.465Z,
    updatedAt: 2023-10-04T22:32:12.465Z,
    __v: 0
  },
  {
    _id: new ObjectId("651de8854ee4b125468e6921"),
    name: 'Otto',
    message: 'I from hightower',
    createdAt: 2023-10-04T22:34:45.179Z,
    updatedAt: 2023-10-04T22:34:45.179Z,
    __v: 0
  }
]

如果我用 {{this}} 替换 {{this.name}} 它会显示

{
    _id: new ObjectId("651de76a44d50f1d9cfedede"),
    name: 'Lucy',
    message: 'I way',
    createdAt: 2023-10-04T22:30:02.377Z,
    updatedAt: 2023-10-04T22:30:02.377Z,
    __v: 0
  }

用 {{name}} 替换 {{this.name}} 也不起作用（该块将保持空白）

这看起来与 how-to-iterate-over-array-of-objects-in-handlebars 非常相似，但简而言之，只是丢失

this.

- 它隐含为

#each

的一部分（尽管 文档根本没有说明这一点）：

    {{#each result}}
    <tr>
      <th scope="row">{{@index}}</th>
      <td>{{name}}</td>
    </tr>
    {{/each}}
