如何訪問HTML中的Collectin對象數據使用流星？

Question

我需要知道在HTML中訪問的集合對象的數據，如下圖所示：

var fieldData = [ 

     {fieldName: "Hcare1", 

     fieldOptions: [ "Bike","Car","TV","Radio","etc"] 

     }, 

     {fieldName: "Hcare2", 

     fieldOptions: [ "Bike1","Car1","TV1","Radio1","etc"] 
     }, 

    {fieldName: "Hcare3", 

     fieldOptions: [ "Bike2","Car2","TV2","Radio2","etc"] 
     } 

    ]; 

在上面的代碼如何訪問fieldOptions在html.The fieldData數據插入到一個集合，即收藏集名稱Fields。我對流星很陌生，所以請你建議我該怎麼做？

Answer 1

在蒙戈控制檯：

db.foo.findOne().fieldOptions; 
[ "Bike", "Car", "TV", "Radio", "etc" ] 

或者在客戶端：

collectionName.findOne().fieldOptions; 

在JS：

Template.your_layout.helpers({ 
    fieldOptions: function() { 
    Fields.findOne().fieldOptions; 
    } 
}); 

在HTML：

{{#each fieldOptions}} 
    {{this}} 
{{/each}}
