流星使用Spacebars逻辑不服​​从逻辑

Question

我有一个模板助手返回一个会议的价值，在这种情况下它返回的人数1：

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

我的模板有一个表，我试图根据辅助函数的值将表中的一部分打印到表中。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的值返回值1，模板也会在{{#if curWeek 2}}下运行逻辑，所以两者都在表中。我只希望{{#if curWeek 1}}下的部分运行，因为这就是值。我没有正确使用逻辑？

<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}}

     <tr>

     <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>

你的帮手没有测试平等。你有：

{{#if curWeek 1}} 

但是你的助手只是返回当前的一周，并不期望一个参数。

只需将参数添加到您的辅助函数，然后返回一个布尔值：

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