如何使Handlebars帮助器知道Ember绑定？ [英] How do you make a Handlebars helper that is aware of Ember bindings?

问题描述

当我尝试将Ember绑定或计算属性传递给自定义Handlebars帮助器时，帮助程序将接收字符串而不是该值。如何获得帮助者的价值？

When I try to pass an Ember binding or computed property to a custom Handlebars helper, the helper receives the string instead of the value. How do I get the value into the helper?

模板：

{{my_helper my.binding}}

帮助者收到my.binding而不是

The helper receives "my.binding" instead of the corresponding value.

推荐答案

前几天，一个推高手解决了问题：
使用Ember.Handlebars.registerBoundHelper。

A few days ago a push on the master solved the problem : use Ember.Handlebars.registerBoundHelper.

Ember.Handlebars.registerBoundHelper('myHelper', 
    function(myBinding, options) {
        return myDealWith(myBinding);
    }
);
