Answer 1

You need to pass de contactNo parameter in your query:
function getAll() {
$.ajax({
url: '{{ route('Myadds', app()->getLocale()) }}',
type: 'GET',
data: {
contact_no: contactNo,
},
})
.done(function(data) {
alert("run")
$.each(data, function(index, val) {
$('#data').append('<tr>')
$('#data').append('<td>'+val.id+'</td>')
$('#data').append('<td>'+val.Sdescription+'</td>')
$('#data').append('<td>'+val.created_at+'</td>')
$('#data').append('<td><button class="btn btn-xs btn-danger" data-id="'+val.id+'">Delete</button><button class="btn btn-xs btn-info" data-id="'+val.id+'">Edit</button></td>')
$('#data').append('</tr>')
});
})
.fail(function() {
alert("fail")
console.log("error");
})
}
So in your controller now you can filter:
public function getData(Request $request){
$contact_no = $request->contact_no;
$query = DB::table('my_table');
if($contact_no){
$query->where('contact_no',$contact_no)
}
return response()->json($query->get());
}
Or directly use the session of the user:
public function getData(Request $request){
$contact_no = Auth::user()->ContactNo;
$query = DB::table('my_table');
$query->where('contact_no',$contact_no)
return response()->json($query->get());
}

Answer 2

public function Myadds(){
try{
return add::where('userID', Auth::user()->ContactNo)->get();
}catch(Exception $e){
return 'false';
}
}
