我有一个页面，其中包含一个表格，用于显示数据库中的用户列表，我使用分页仅显示每页10个用户如何更改用户数量取决于下拉菜单中选择的数量，例如在第二个表格下方的链接中包含此处所需的“显示条目”。那么我可以将所选项目中的值传递给控制器吗？或者有不同的方法可以做到这一点吗？ https://adminlte.io/themes/AdminLTE/pages/tables/data.html p> div>

You will have to make a variable which will hold the pageinate data, suppose you are sending through ajax, use the pageinateData and in your controller you can call something like this:

$users = App\User::paginate($request->pageinateData);

So every time you can call with this data set.

EDIT:

In your controller you can do something like this:

public function pUserList(Request $request) {
    $data = [];
    $data['users'] = App\User::orderBy('id', 'desc')->paginate($request->pageinateData);


    return view('userlist', $data);
}

$this will give you errors. You can use on change in jquery to get the values

$(document).ready(function() {
  $('#issueinput5').on('change', function() {
    alert($('#issueinput5').val());
    $.ajax({
        url:'your url here',
        method:'POST',
        data:{'pageinateData':$('#issueinput5').val(),},
        success:function(d){
         // Do your code...
        }
   });
  });
});

Edit 2:

For the csrf_token you need to do the following: add to your html headers

<meta name="csrf-token" content="{{ csrf_token() }}">

and in ajax call you need to have:

$(document).ready(function() {
  $('#issueinput5').on('change', function() {
    $.ajax({
        url:'/lists/user',
        method:'POST',
        headers: { 'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content') },
        data:{'pageinateData':$('#issueinput5').val(),},
        success:function(d){
          console.log(d)
        }
   });
  });
});

Hope this helps.

You can try to do this

 $(document).ready(function(){
    $('#issueinput5').on('change',function(){
       $.ajax({
        url:'supply your url here',
        method:'POST',
        data:{'priority':$(this).val(),},
        success:function(d){
          console.log(d)
        }
       });
      })
    })
