下面是一些样板代码,您可以使用自定义助手创建强大的模板,同时仍然使用少量代码。
它包含两个助手:
- 一个将字符串更改为大写。在演示代码中将一个
@key
值传递给它。
- 一来增加一个数值。在演示代码中将一个
@index
值传递给它。
模板table.hbs
:
{{#if table}}
<table>
<thead>
<tr>
<th style="width: 2%;">#</th>
{{#each table.0}}
<th nowrap="nowrap">
{{uppercase @key}}
</th>
{{/each}}
</tr>
</thead>
<tbody>
{{#each table}}
<tr>
<th>{{increment @index}}</th>
{{#each this}}
<td><input type="text" value="{{this}}" /></td>
{{/each}}

{{/each}}

{{#if paginator}}
<nav class="pagination">
