在新视图后过滤数据后，复选框变为未选中状态.如何在过滤数据后阻止复选框未选中

Question

>我在侧边栏中有一个制造商列表，当选中复选框时，数据将根据制造商进行过滤。 但是当视图是加载数据时，会过滤数据，但复选框变为未选中状态。我们如何停止复选框以在过滤数据后变为未选中状态。

在 Laravel 5.1 上工作

控制器

      $productsFeatured = Product::select('products.id', 'products.name','products.low_emitting_material_prerequisite_file',
            'manufacturers.phone','manufacturers.address','manufacturers.linkedin_url','manufacturers.city', 'products.specs_file','products.specs_file_url','products.low_emitting_material_credit_file', 'products.logo', 'products.division_id', 'products.section_id', 'products.manufacturer_id', 'divisions.name as division_name', 'divisions.code as division_code', 'sections.name as section_name', 'sections.code')
                    ->whereIn('products.status', ['active'])
                    ->where(function ($query) {
                        $query->where('products.low_emitting_material_prerequisite_file', '!=', '');
                    })
                    ->where('users.user_type', 'manufacturer_paid')
                    ->leftJoin('products_selected_leeds', 'products.id', '=', 'products_selected_leeds.product_id')
                    ->leftJoin('sections', 'products.section_id', '=', 'sections.id')
                    ->leftJoin('divisions', 'products.division_id', '=', 'divisions.id')
                    ->join('manufacturers', 'products.manufacturer_id', '=', 'manufacturers.id')
                    ->join('users', 'manufacturers.user_id', '=', 'users.id')
                    ->orderBy('divisions.code', 'asc')
                    ->orderBy('sections.code', 'asc')
                    ->groupBy('products.id');
                    if($request->ajax() && $request->manufacturer){
                        $productsFeatured->whereIn('products.manufacturer_id', $request->manufacturer);
                        $productsFeatured = $productsFeatured->get();                     
                    } else{
                        $productsFeatured = $productsFeatured->get();
                    }

   if($request->ajax()){
                    return  view('guest::new_design_frontend.product-library')->with($productsFeatured); 
            }else{
                return  view('guest::new_design_frontend.product-library')->with($productsFeatured); 
            }

脚本

$(document).ready(function() {
        // filter_data();
        function filter_data() {
            var manufacturer = get_filter('manufacturer');
            $.ajax({   
                url: "{{url('CHPS')}}",
                method: 'POST',
                headers: {
                        'X-CSRF-Token': $('meta[name="csrf-token"]').attr('content')
                    },
                data:{manufacturer:manufacturer} ,
                success:function(data){
                 $('body').html();
                    $('body').html(data);
                }
            });
        }
        function get_filter(class_name) {
            var filter = [];
            $('.'+class_name+':checked').each(function(){
            filter.push($(this).val());
        });
        return filter
        }
        $('.common_selector').click(function(){
        filter_data();
    });
    });

视图

manufacturers as sidebar
 @foreach($manufacturers as $leedsManufacturer)
                                <div class="post" id="post{{$leedsManufacturer['mfgg_id']}}">
                                    <label class=" my-checkbox gry2" id="manufacturer">{{str_limit($leedsManufacturer['mfgg_name'], 300)}}
                                        <input type="checkbox" class="manufacturer common_selector" name="manufacturer[]" value="{{$leedsManufacturer['mfgg_id']}}">
                                        <span class="checkmark"></span>
                                    </label>
                                </div>
                         @endforeach

checkbox is unchecked after filter the data whereas it should be not

Answer 1

传递$request>制造商值以供查看。然后你需要用检查数组$request>制造商检查当前值$leedsManufacturer['mfgg_id']，如果是，则添加属性"选中">

<input type="checkbox" class="manufacturer common_selector" name="manufacturer[]" value="{{$leedsManufacturer['mfgg_id']}}"  {{(in_array($leedsManufacturer['mfgg_id'],$checkedManufactureArray)?"checked":"")}}>

您需要传递选中的值才能查看
$checkedManufactureArray=$request->制造商;
