我基本上使用 cmets 中提到的我的博客文章中的 MultipleSelectionFilterComponent。该组件将负责管理不同复选框的选择并将过滤器功能发送到控制器。在那里,您可以使用该功能来过滤数据。详情可以参考我的帖子。
Here is the working demo.
代码看起来像
App.ExamsExamRoute = Ember.Route.extend({
model: function(params) {
return this.store.find('exam', params.exam_id).then(function (exam) {
console.log("found", exam);
return exam;
});
},
setupController: function(controller, model) {
this._super(controller, model);
controller.set('filteredContent', model.get('data.subjects'));
}
});
App.ExamsExamController = Em.ObjectController.extend({
filteredContent: [],
actions: {
filterBySubject: function(filterFn) {
this.set('filteredContent',
this.get('model.data.subjects').filter(filterFn));
}
}
});
<ul class="list-group">
{{#multiple-selection-filter filter-key-path="name"
action="filterBySubject"}}
{{#each subject in model.subjects}}
<li class="">
<label>
<input type="checkbox" class="item-checkbox" {{bind-attr
value=subject.name}}/>
{{subject.name}}
</label>
</li>
{{/each}}
{{/multiple-selection-filter}}
</ul>
<h3>Subjects Details - </h3>
{{#each subject in filteredContent}}
<div class="col-md-3 well">
{{subject.name}}
<br>{{subject.description}}
</div>
{{/each}}
这是MultipleSelectionFilterComponent的代码。
App.MultipleSelectionFilterComponent = Em.Component.extend({
selectedItems: [],
click: function(event) {
var el = Em.$(event.target);
var filterFn;
if(el.is('input[type=checkbox]')) {
if(el.is(':checked')) {
this.get('selectedItems').pushObject(el.val());
} else {
this.get('selectedItems').removeObject(el.val());
}
}
if(this.get('selectedItems.length')) {
filterFn = function(item) {
return this.get('selectedItems')
.contains(Em.get(item, this.get('filter-key-path')));
}.bind(this);
} else {
filterFn = function() {return true;};
}
this.sendAction('action', filterFn);
}
});
