Question

从JavaScript按钮单击后，我将使用重定向页面

 window.location.href = '//dziennik_zdarzen?id_seo=5';

接下来，我要将其从我的路线传递给控制器，这部分无效

Route::get('dziennik_zdarzen', ['uses'=>'Dziennik_zdarzenController@get_datatable']);

我尝试了很多尝试，例如尝试从url中获取它，但没有成功。所以我试图将其传递给Dziennik_zdarzenController @ get_datatable。我在windows.location.href中将网址更改为类似“ // dziennik_zdarzen / 5”的网址，然后我尝试在路由中传递它。像这样：

Route::get('dziennik_zdarzen/{id_seo}', ['uses'=>'Dziennik_zdarzenController@get_datatable']);

仍然无法正常工作

这是我的控制人

<?php
namespace App\Http\Controllers;

use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Route;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use Yajra\Datatables\Datatables;
use App\Dziennik_zdarzen;

class Dziennik_zdarzenController extends Controller
{
  public function get_datatable($id_seo)
  {

  return $id_seo;

  }
}
?>

如果您能指导我我做错了什么，我将不胜感激

Answer 1

您将id_seo发送为查询参数。您可以使用控制器中的Request对象访问它

<?php
namespace App\Http\Controllers;

use Illuminate\Support\Facades\Input;
use Illuminate\Support\Facades\Route;
use Illuminate\Support\Facades\DB;
use Illuminate\Http\Request;
use Yajra\Datatables\Datatables;
use App\Dziennik_zdarzen;

class Dziennik_zdarzenController extends Controller
{
  public function get_datatable(Request $request)
  {

      return $request->id_seo;

  }
}
?>

如果要将其作为路由参数发送

window.location.href = '//dziennik_zdarzen/5';

在控制器中：

Aggregation aggregation = newAggregation(
                    match(
                        where("domain").is(domain)
                        .and("contents.contentName").is(templateName)
                        .and("locale").in(criteria.getLocales())), 
                        project().and(new AggregationExpression() {
                        @Override
                        public Document toDocument(AggregationOperationContext aggregationOperationContext) {
                            DBObject filterExpression = new BasicDBObject();
                            filterExpression.put("input", "$contents.fields");
                            filterExpression.put("as", "field");
                            filterExpression.put("cond",
                                    new BasicDBObject("$eq", Arrays.<Object>asList("$$field.title", "Company Name")));
                            return new Document("$filter", filterExpression);
                        }

                }).as("field"));
AggregationResults<MyClass> list = mongoOperations.aggregate(aggregation, MyClass.class,
                MyClass.class);

路线：

        ],

            var location = 0;
            vm.gridApi = gridApi;
            //vm.gridApi.grid.registerRowsProcessor( vm.semesterFilter, 8 );
            gridApi.edit.on.afterCellEdit($scope, function (rowEntity, colDef, newValue, oldValue) {
                console.log(rowEntity._id)
                for (; location < vm.gridOptionsSemester.data.length; location++) {
                    if (vm.gridOptionsSemester.data[location]._id === rowEntity._id) {
                        break;
                    }

                }

                var semUpdate = vm.gridOptionsSemester.data[location];

                semUpdate.colDef = newValue;
                console.log(semUpdate._id + '     ' + semUpdate.colDef + '  ' + vm.gridOptionsSemester.data[location].endDate);
                ProjectService.editTerm(semUpdate, semUpdate._id).then(function (success) {
                    console.log("Successfully Edited Semester");
                    semesterchange_msg();
                    resetSemSettings();



                });

            });
        },

    };

不需要use语句，依赖项注入或route参数。

laravel将参数从url传递到路由和控制器
