javascript - Handlebars 如果 var length 大于

Question

我目前正在尝试使用 Foundation 电子邮件和 Handlebars 设置一些电子邮件模板。我试图根据值是否传递给组件来渲染一些标题，但是我似乎无法让它工作。我在这里做错了什么？

标题1.html

<h1>{{text}}</h1>

段落.html

<row class="card">
    <columns>
        <wrapper class="inner-padding">
            {{#if (eq heading-1.length > 0)}}
                {{> heading-1 text="Test"}}
            {{else}}
                <h1>failed</h1>
            {{/if}}
            <p>
                {{text}}
            </p>
        </wrapper>
    </columns>
</row>

index.html

<container>
  <row>
    <columns class="content">
      {{> paragraph
        heading-1="test"
        text="Lorem ipsum dolor sit amet, consectetur adipisicing elit. Amet dolorem molestias nam odit suscipit velit.
        Ab aliquam at autem dignissimos dolorum ipsam magnam molestiae officia, quae quo, veniam veritatis voluptatibus?"
      }}
    </columns>
  </row>
</container>

创建 Handlebars 助手:

Handlebars.registerHelper('checklength', function (v1, v2, options) {
'use strict';
   if (v1.length>v2) {
     return options.fn(this);
  }
  return options.inverse(this);
});

用途:

{{#checklength Title 0}}   //Title is property and 0 is length
             <p>Heading</p>
      {{else}}
             <h1>failed</h1>
      {{/checklength}}
