Pass Id from ajax to controller - Laravel

I am trying to pass my id from ajax to my controller. I mostly see that it is being done through the url but is there any other way i could do this without using the URL?

View

          </div>
          <div class="form-group">
<label for="select" class="col-lg-2 control-label">Item</label>
<div class="col-lg-10">
<select class="form-control" id="item" name="item" mulitple>
<option >
</option>
</select>

</select>
</div>
</div>


$('#item').change(function()
        {    
             id =$(this).val();
            alert(id);
        }

        )

Controller

public function store(Request $request)

{
    $id = $request->id;
    $item = Item::all()->where('id',$id)->first();

}

Since you are using jquery, you can use jquery's ajax method to send out variables or data to your controller on laravel. Just be sure to read on form method spoofing from the laravel docs in any case at all, check it out here.

Jquery's ajax documentation goes here.

Here's how it'd look like:

function usersManagementAjax(requestType, url, userData, modalSelector, modalFailedSelector){
modalSelector.modal('hide');
$.ajax({
    type: requestType,
    url: url,
    data: userData,
    dataType: "json",
    success: function(data){
        modalSuccess.modal('show');
    },
    error: function(data){
        if(data.responseJSON.errors.contactNumber){
            contactGrp.removeClass('has-success');
            contactGrp.addClass('has-error');
            contactGrpError.removeClass('hidden');
            contactError = true;
            contactErrorText.text(data.responseJSON.errors.contactNumber[0]);
            isValid();
        }

        if(data.responseJSON.errors.email){
            emailGrp.removeClass('has-success');
            emailGrp.addClass('has-error');
            emailGrpError.removeClass('hidden');
            emailError = true;
            emailErrorText.text(data.responseJSON.errors.email[0]);
            isValid();
        }
        modalFailedSelector.modal('show');
    }
}); }

And here's how a function in a controller would look like:

 public function update(Request $request)
{
    $userId = $request->id;
    $updateRules = [
        'name' => 'required|string|max:255',
        'email' => [
            'required',
            'string',
            'email',
            'max:120',
            Rule::unique('users')->ignore($userId)
        ],
        'college' => 'required|string|min:1|max:1',
        'contactNumber' => [
            'required',
            'string',
            'min:11',
            'max:11',
            Rule::unique('users')->ignore($userId)
        ]
    ];

    $validation = Validator::make(Input::all(), $updateRules);
    if($validation->fails()){
        return Response::json(
            array('errors' => $validation->getMessageBag()->toArray()), 404);
    }

    else{
        $user = User::find($userId);
        $user->name = $request->name;
        if(Auth::user()->role->role != "Admin"){
            $user->roleID = Role::$defaultRoleId;
        }

        else{
            $user->roleID = $request->role;
        }
        $user->collegeID = $request->college;
        $user->contactNumber = $request->contactNumber;
        $user->email = $request->email;
        $user->save();

        return response()->json($user);
    }
}

Be aware that this is just a code sample and I have only meant to give you an idea on how to work around this. These are some code snippets from my current project.

EDIT: I forgot to mention that for ajax requests to work on a laravel project, you must include a X-CSRF-TOKEN for every ajax request. (Or you can simply remove the VerifyCsrfToken middleware) Link about this goes here.
