我想应该是这样的
public function viewStudent(Request $request, $studentid = null)
{
if(!Auth::check())
{
return redirect('/');
}
if($request)
{
// echo outputs to the server, but you should really return something
// for the requester, thus we will return "YES" to the response
// and since we are returning, it will return and no further executions will made.
return 'yes';
}
if(!is_null($studentid))
{
$data['allstates'] = DB::table('tblstates')->get();
$data['alllga'] = DB::table('tbl_lga')->get();
$data['studentinfo'] = DB::table('tblstudents')
->where('id', $studentid)
->first();
return view('Students.viewstudents', $data);
}
return redirect('/all/students');
}
您可以使用returnjson将数据返回到ajax请求，如
return response()->json(['success' => 'yes']);
不要使用echo作为ajax响应的返回值在ajax调用中根据需要执行一些功能。我正在使用搜索输入筛选表数据
$.ajax({
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
type :"POST",
url :"{{route('filter')}}",
dataType:"JSON",
data :{keyword:keyword,'_token':'{!!csrf_token()!!}'},
success :function(response)
{
if (response.status=='success')
{
$('#table_body').html(response.data);
}
}
});
public function filter(Request $r)
{
$keyword=$r->keyword;
$orders=DB::table('orders')->where('print_orders.address','like','%' .$keyword. '%')->paginate(50);
$html=view('orders',compact('orders'))->render();
if ($this->check_count($orders)>0)
{
return response::json(['status'=>'success','data'=>$html]);
}
else
{
return response::json(['status'=>'fail','Nothing Found!!']);
}
}
你能告诉我们你的web.php文件中的路线吗？该特定路由为preferredexit（），将使脚本退出。因此，首选
返回null $.ajax({
headers: {'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')},
type :"POST",
url :"{{route('filter')}}",
dataType:"JSON",
data :{keyword:keyword,'_token':'{!!csrf_token()!!}'},
success :function(response)
{
if (response.status=='success')
{
$('#table_body').html(response.data);
}
}
});
public function filter(Request $r)
{
$keyword=$r->keyword;
$orders=DB::table('orders')->where('print_orders.address','like','%' .$keyword. '%')->paginate(50);
$html=view('orders',compact('orders'))->render();
if ($this->check_count($orders)>0)
{
return response::json(['status'=>'success','data'=>$html]);
}
else
{
return response::json(['status'=>'fail','Nothing Found!!']);
}
}
