在 Meteor 中使用空格键逻辑不遵守逻辑

Question

我有一个模板助手，它 returns 会话的值，在本例中它以数字 1 返回：

Template.Student.helpers({
  curWeek: function () {
    return Session.get('CurrentWeek').substr(0, 1);
},

我的模板有一个 table，我试图根据辅助函数的值将它的一部分打印到 table。所以我在模板中有一些逻辑来打印正确的部分。但它不服从逻辑。即使 curWeek 的值 returns 值为 1，模板运行也是 {{#if curWeek 2}} 下的逻辑，因此两者都在 table 中。我只想要 {{#if curWeek 1}} 到运行下的部分，因为这就是值。我没有正确使用逻辑吗？

<template name="Student">
  {{#modalizeBody}}
  <table class="bordered narrow">
    <thead>
      <tr>
        <th>Name</th>
        <th>Shift</th>
        <th>Age</th>
        <th>Sex</th>
        <th>Level</th>
        <th>Sun</th>
        <th>Mon</th>
        <th>Tue</th>
        <th>Wed</th>
        <th>Thu</th>
        <th>Fri</th>
        <th>Sat</th>
      </tr>
    </thead>
  <tbody>
  {{#each StudsWk1Master}}
    {{#if curWeek 1}}
      <tr>
        <td>{{FullName}}</td>
        <td>{{RoomWk1}}</td>
        <td>{{calculateAge Bdate}}</td>
        <td>{{Sex}}</td>
        <td>{{Level}}</td>
        <td>{{formatName this.Teachers.Week1.Sunday}}</td>
        <td>{{formatName this.Teachers.Week1.Monday}}</td>
        <td>{{formatName this.Teachers.Week1.Tuesday}}</td>
        <td>{{formatName this.Teachers.Week1.Wednesday}}</td>
        <td>{{formatName this.Teachers.Week1.Thursday}}</td>
        <td>{{formatName this.Teachers.Week1.Friday}}</td>
        <td>{{formatName this.Teachers.Week1.Saturday}}</td>
      </tr>
    {{/if}}
  {{/each}}
  {{#each StudsWk1Master}}
    {{#if curWeek 2}}
      <tr>
        <td>{{FullName}}</td>
        <td>{{RoomWk2}}</td>
        <td>{{calculateAge Bdate}}</td>
        <td>{{Sex}}</td>
        <td>{{Level}}</td>
        <td>{{formatName this.Teachers.Week2.Sunday}}</td>
        <td>{{formatName this.Teachers.Week2.Monday}}</td>
        <td>{{formatName this.Teachers.Week2.Tuesday}}</td>
        <td>{{formatName this.Teachers.Week2.Wednesday}}</td>
        <td>{{formatName this.Teachers.Week2.Thursday}}</td>
        <td>{{formatName this.Teachers.Week2.Friday}}</td>
        <td>{{formatName this.Teachers.Week2.Saturday}}</td>
      </tr>
    {{/if}}
  {{/each}}
  </tbody>
 </table>
{{/modalizeBody}}
</template>

Answer 1

您的助手未测试是否相等。你有：

{{#if curWeek 1}}

但是您的助手只是 return 当前一周，不需要参数。

只需将参数添加到您的辅助函数，然后 return 一个布尔值：

Template.Student.helpers({
  curWeek: function (value) {
    return Session.get('CurrentWeek').substr(0, 1) === value;
},
