问题描述

我正在寻找如何使用yield语句访问当前模型。任何想法?

模型

 模型:[{
id:1,
name:'Red',
value:'#ff0000'
},{
id:2,
'name':'Yellow',
value:'#ffff00'
},{
id:3,
name:'Blue',
value:'# 0000ff'
}];

模板
< pre $ {{#table-list models = models config = colorModelTableListConfig}}
{{model.id}}
{{model.name}}
{{model.value}}
{{/ table-list}}

组件(表列表)

 <! - 搜索标记 - > 
< table>
{{#each th in config.tableHeaders}}
< th> {{th}}< / th>
{{/ each}}

{{#模型中的每个模型}}
{{yield}}
{{/每个}}
< /表>
<! - 分页标记 - >

附注这会导致我的搜索,分页和其他功能的问题。

答案

Ember yield param pass

解决方案

您可以将参数传递给yield块:

  {{yield model}} 

如果需要,您可以调整其他名称:

  {{#with model as foobar}} 
{{yield foobar}}
{{/ with}}

您可以使用每个助手做类似的事情:

  {{#模型中的每个模型都是| foobar |}} 
{{yield foobar}}
{{/ each}}

I'm looking for how to access the current model with-in an each from a yield statement. Any ideas?

Model

models: [{
   id: 1,
   name:'Red',
   value: '#ff0000'
}, {
  id: 2,
  name:'Yellow',
  value: '#ffff00'
}, {
  id: 3,
  name:'Blue',
  value: '#0000ff'
}];

Template

{{#table-list models=models config=colorModelTableListConfig}}
  {{model.id}}
  {{model.name}}
  {{model.value}}
{{/table-list}}

Component (table-list)

<!-- Searching markup-->
<table>
  {{#each th in config.tableHeaders}}
    <th>{{th}}</th>
  {{/each}}

  {{#each model in models}}
    {{yield}}
  {{/each}}
</table>
<!-- Pagination markup-->

Side-note I can't throw the each inside the yield, this will cause issues with my searching, pagination and other functionality

Answer

Ember yield param passing

解决方案

You can pass parameters to the yield block:

{{yield model}}

If necessary you can adjust for a different name:

{{#with model as foobar}}
  {{yield foobar}}
{{/with}}

You can do something similar using the each helper:

{{#each model in models as |foobar|}}
  {{yield foobar}}
{{/each}}
