Laravel 5.1 Ajax从Blade View获取HTML

Question

我在ItemsController中有一个myitems($ filter)方法,用于加载myitems.blade视图.

视图将项目列表作为标签和文本框以获取项目数量($项目从myitems方法传递到myitems视图,并且还有一个模型表单绑定项目模型)

我有一个选择框,有选项1.全部,2.过期和3.新

当我更改选择时,我想从控制器获取新的$ items并使用新项列表重新创建表单.

我正在使用jquery来警告选择已更改.但我无法弄清楚如何从ajax调用myitems($ filter)并重定向以创建items.blade页面.

Answer 1

路线

//Note the ? in parameter, it says parameter is optional
Route::get('/myitems/{filter?}', 
    ['as' => 'myitems.list', 'uses' => 'ItemController@myitems']
);

调节器

...
public function myitems(Request $request, $filter = null)
{
    if (empty($filter)) $filter=1;

    $items = Item::where('item_type', $filter)->get();

    // if ajax call just return the partial that displays the list
    if ($request->ajax()) {
        return view('_itemlist', compact('items'));
    }

    // passed as options to input select
    $filters= [
           'All' => '0',
           'New' => '1',
           'Expired' => '2'
    ];
    return view('itempagewith_defaultitemlist', compact('items','filters'));
}
...

视图

查看itempagewith_defaultitemlist.blade.php

<div class="container">
{!! Form::model($myitems, ['route' => 'myitems.list', 'class'=>'form-horizontal', 'files' => true]) !!}

<div id="filterselectbox">
    <div class="form-group">
            {!!Form::label('filterselectbox','*Filter:',['class'=>'control-label']) !!}            
            {!!Form::select('filterselectbox', $filters, null, ['class'=>'form-control ']) !!}
     </div>
</div>
{!! Form::close() !!}

<div id="item-container">
    @include('_itemlist')
</div>

<script>
$('#filterselectbox').change(function() {
    var id = $('#filterselectbox').val();
    var ajaxurl = '{{route('myitems', ':id')}}';
    ajaxurl = ajaxurl.replace(':id', id);
    $.ajax({
        url: ajaxurl,
        type: "GET",
        success: function(data){
            $data = $(data); // the HTML content that controller has produced
            $('#item-container').hide().html($data).fadeIn();
        }
    });
});
</script>                   

</div>

局部视图_itemlist.blade.php

 <ul>
     @foreach ($items as $item)
    <li>{{ $item->name }}</li>
     @endforeach
 </ul>
