Javascript 是否可以在把手模板中嵌套if/else语句？

我想知道是否可以使用手柄嵌套多个if/else语句？到目前为止，我所有的尝试都导致了编译错误，我想做的如下：

{{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}}

---

虽然这是可行的，但最好不要为这种简单条件的每个实例都编写一个helper函数。

我相信ifs需要一个#

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}}

{{{#if address}

地址.第1行
地址.第2行
{{{#if address.line3}
address.line3
{{/if}
{{{#if address.line4}
address.line4
{{/if}

{{else}
没有地址
{{/if}

我的荣幸@HenryWilson:）

{{#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}}
