未捕获的类型错误：r.getClientRects 不是函数 jquery.min.js:2

Question

Hi I don't understand what the meaning of the error is in the web console.

Uncaught TypeError: r.getClientRects is not a function jquery.min.js:2

I am trying to build an autocomplete search form in laravel Based on a bootstrap theme i downloaded.

It works but the dropdown is misaligned to the text box I suspect JQuery because of that error and the fact that in a different bootstrap theme I had, it worked I have my script links as follows

<link href="http://myurl.com/vendor/bootstrap/css/bootstrap.min.css" 
rel="stylesheet">
<link href="http://myurl.com/vendor/fontawesome-free/css/all.min.css" 
rel="stylesheet">

</script>
<script src="http://myurl.com/vendor/jquery- 
easing/jquery.easing.min.js"></script>
<script src="http://myurl.com/js/grayscale.min.js"></script>

My form:

 <form class="form-inline d-flex">


            <input class="form-control autocomplete_txt input-lg flex-fill mr-0 mr-sm-2 mb-3 mb-sm-0" 
                   type='text' data-type="EmpService" id='EmpService_1' name='EmpService[]' autocomplete="off" placeholder="looking for...">

                       <button type="submit" class="btn btn-primary mx-auto">Search</button>
             <div class="col-xs-4 g-recaptcha" data-sitekey="6Lf9mW4UAAAAACtNJIuXY9VlCZ5kg0Ys7Y3ancH_"></div>   

</form>

My Javascript:

$(document).on('focus','.autocomplete_txt',function(){
  type = $(this).data('type');

  if(type =='EmpService' )autoType='EmployeeService'; 



   $(this).autocomplete({
       minLength: 0,
       source: function( request, response ) {
            $.ajax({
                url: "http://spanibox.com/searchajax",
                dataType: "json",
                data: {
                    term : request.term,
                    type : type,
                },
                success: function(data) {
                    var array = $.map(data, function (item) {
                       return {
                           label: item[autoType],
                           value: item[autoType],
                           data : item
                       }
                   });
                    response(array)
                }
            });
       },
       select: function( event, ui ) {
           var data = ui.item.data;           
           id_arr = $(this).attr('id');
           id = id_arr.split("_");
           elementId = id[id.length-1];
           $('#EmpService_'+elementId).val(data.name);

       }
   });

The problem is likely due to using jQuery 3.1. Try to add :

<script src="https://code.jquery.com/jquery-migrate-3.0.0.min.js"></script>
