流星每个循环数据都不显示

Question

在每个循环中数据没有显示.value =“{{param_type}}”没有显示。请帮助我。

{{ #each api_method_param_data }}
    <select id="param_type"> 
    {{#each dropdown}}
    {{#if isSelected this param_type}}  
    <option value="{{param_type}}" selected="selected"> {{this}} </option>
    {{else}}
    <option value="{{param_type}}" > {{this}} </option>
    {{/if}}
    {{/each}}
    </select>
 {{/each}}

这是辅助函数

 Template.apimethodchange.isSelected = function(fooToCheck, recordFoo)
  {
    var checkrec = "";  
    for(var i=0;i<recordFoo.length;i++)
    {
        checkrec = checkrec + recordFoo[i];
    }
    console.log(checkrec + fooToCheck);
    return (fooToCheck == checkrec);
  };

Template.apimethodchange.dropdown = ["string","array","int","boolean","double","struct"];

尝试使用../访问父上下文

<option value="{{../param_type}}" selected="selected"> {{this}} </option>
