是否可以在Handlebars模板中嵌套if/else语句？

Question

我想知道是否可以使用把手嵌套多个if/else语句？到目前为止,我所有的尝试都导致编译错误,我想做的是如下:

{{if address}}
    <ul>
    <li>address.line1</li>
    <li>address.line2</li>
    {{if address.line3}}<li>address.line3</li>{{/if}}
    {{if address.line4}}<li>address.line4</li>{{/if}}
{{else}}
   No address given
{{/if}}

我在这里尝试的是可以实现的吗？它总是导致解析器错误,因此我通过编写帮助程序来处理吐出地址(处理javascript中line3/line4的条件性)来解决它:

{{if address}}
    {{formatAddress address}}
{{else}}
   No address given
{{/if}}

虽然这有效,但不必为这种简单条件的每个实例编写一个辅助函数.

我相信如果需要先前#

试试这个.

{{#if address}}
    <ul>
        <li>address.line1</li>
        <li>address.line2</li>
        {{#if address.line3}}<li>address.line3</li>{{/if}}
        {{#if address.line4}}<li>address.line4</li>{{/if}}
    </ul>
{{else}}
   No address given
{{/if}}
