模板-名称和品牌等其他属性正确显示
<script type="text/x-handlebars" data-template-name="designer">
{{outlet}}
<div id="product-details">
<h4>Style</h4>
<p id="name">{{name}}</p>
<p id="brand">{{brand}}</p>
<p id="description">{{description}}</p>
<p id="materials">{{materials}}</p>
<h4>Color</h4>
{{log garment_colors}}
<div id="color-list">
{{#each garment_colors}}
<label class="btn" style="background-color:{{color}}">
<input type="radio" name="color" value="{{name}}">
</label>
{{/each}}
</div>
</div>
</script>
{{outlet}}
风格
{{name}
{{brand}
{{description}
{{materials}
颜色
{{log garment_colors}}
{{{每件衣服的颜色}
{{/每个}}
重新适应程序
要求属性名称为服装颜色
"garment_colors":[
66,
67,
68
]
在Handlebar中不支持添加这样的值,这取决于某些版本,它会将变形标记添加到html中
<label class="btn" style="background-color:{{color}}">
<input type="radio" name="color" value="{{name}}">
</label>
您需要将其解除绑定,这将直接将其注入模板,但不会绑定到模型
<label class="btn" style="background-color:{{unbound color}}">
<input type="radio" name="color" value="{{unbound name}}">
</label>
或者需要使用bind attr将属性绑定到属性
<label class="btn" {{bind-attr style=someProperty}}>
<input type="radio" name="color" {{bind-attr value=name}}>
</label>
示例:是否显示返回的json。模板不起作用了?刚刚添加了它,谢谢!我不太明白。我正在模板中使用服装颜色。你是说json键应该是“garment_color”而不是“garment_color_ID”?是的,json中的属性(对于RESTAdapter/RESTSerializer)将json键从“garment_color_ID”更改为“garment_color”。很遗憾,这应该是复数,garment_color,它应该与模型中的attr名称匹配。此外,您的模板存在一些问题,我将更新答案。
