流星使用Spacebars邏輯不服​​從邏輯

Question

我有一個模板助手返回一個會議的價值，在這種情況下它返回的人數1：

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

我的模板有一個表，我試圖根據輔助函數的值將表中的一部分打印到表中。所以我在模板中有一些邏輯來打印正確的部分。但它不服從邏輯。即使curWeek的值返回值1，模板也會在{{#if curWeek 2}}下運行邏輯，所以兩者都在表中。我只希望{{#if curWeek 1}}下的部分運行，因爲這就是值。我沒有正確使用邏輯？

<template name="Student"> 
    {{#modalizeBody}} 
    <table class="bordered narrow"> 
    <thead> 
     <tr> 
     <th>Name</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>

Answer 1

你的幫手沒有測試平等。你有：

{{#if curWeek 1}} 

但是你的助手只是返回當前的一週，並不期望一個參數。

只需將參數添加到您的輔助函數，然後返回一個布爾值：

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