Handlebars 在 helper 处获取对象值，无需使用数据进行编译

Question

    <h1>Handlebars JS Example</h1>
<script id="some-template" type="text/x-handlebars-template"> <table>
   {{helper yes}}
</script>
var source = $("#some-template").html(); 
var template = Handlebars.compile(source); 

var data = { 
    yes:'Yes'
}; 

Handlebars.registerHelper('helper', function(person) {
console.log(person);
console.log(data);
console.log(data[person]);
console.log(myFunction(person));
});
$('body').append(template(data));

function myFunction(keyname) {
  return data[keyname];
};

我尝试通过从车把获取的字符串获取数据值。 Why no methods that i tried works?

现在我真的找到了解决方案，问题是当编译模板时我们可以像我的示例一样将对象放入它。但我需要从 var 中获取它并按名称查找它。所以当我使用 up 之类的参数时，它仍然说找不到属性是的。我发现 here that as argument we can use string. And its work, my code will be cleaner. jsFiddle

    var source = $("#some-template").html(); 
var template = Handlebars.compile(source); 

var data = { 
    yes:'Yes'
}; 

    <h1>Handlebars JS Example</h1>
    <script id="some-template" type="text/x-handlebars-template">
       {{helper 'yes'}}
    </script>

    Handlebars.registerHelper('helper', function(person) {
    return data[person];
    });
    $('body').append(template());
