<p> 
            In this example autoComplete uses a local array of strings.</p> 
  
                         
<p> 
            The list contains strings with'Afganistan', 'Albania', 'Angola', 
                'Argentina', 
                     'Madagascar', 'Malaysia', 
               'Bahrain', 'Bangladesh', 'Belarus',    'Belgium',

               'Peru', 'Croatia']

<p> 
            <input type="text" id="searchField" placeholder="Countries"> 
            <ul id="suggestions" data-role="listview" data-inset="true">

            </p> 
  
        </div> 
    </div> 
  
    <script> 
  
        $("#mainPage").bind("pageshow", function(e) { 
  
            var dataList = ['Afganistan', 'Albania', 'Angola',  
                           'Argentina', 
                     'Madagascar', 'Malaysia', 
                            'Bahrain', 'Bangladesh', 'Belarus',    'Belgium',

            $("#searchField").autocomplete({ 
                target: $('#suggestions'), 
                source: dataList, 
                link: 'resultArray.html?term=', 
                minLength: 1, 
                matchFromStart: false 
            }); 
        }); 
    </script> 
  
</body> 
</html> 

“resultArray.html” file: The following demonstrates the code for the “resultArray.html” file used in the above code which is the link file used in the javascript part for the above HTML code.

html

<!DOCTYPE html> 
<html> 
<body> 
   <h2>Result page </h2> 
    <div data-role="page" id="mainPage">         
        <div data-role="content">

                       autocomplete search. 
            </p> 
  
        </div> 
    </div>
