How to attach a jquery autocomplete to input element

问题

I want to attach autocomplete to jquery input element. I downloaded jquery widget v1.12.1 ( only autocomplete) from this link enter link description here.

function maintest () {
        let table;
        let row1;
        let row2;
        let cell0;
        let cell1;
        let header2;
        let autocomplete1;
        
        table = $('<table>');
        table.attr({"id":"testtable"});
     
       
        row1 = $('<tr>');
        table.append(row1);
        header2 = $('<th>').text("Feature/Description");
        row1.append(header2); 
     
        row2 = $('<tr>');
        table.append(row2);
     
        cell1 = $('<td>');
        row2.append(cell1); 
        autocomplete1 = $("<input>").attr({"id" : "selector0"});
        /*$("#selector0").autocomplete( "option", "source", [ "c++", "java", "php", "coldfusion", "javascript", "asp",              "ruby" ] );
        cell1.append(autocomplete1);*/
     
        $("#mainDiv").append(table);


 
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<body onload="maintest()">
  <div id="mainDiv"></div>
</body>

Note :I have commented the autocomplete beacause I didn't find proper cdn to include jquery widget for autocomplete

My requirement is to add autocomplete to input box

It looks like you need to add the autocomplete before you call options on it. Here's a working CodePen version: https://codepen.io/edlucas/pen/mdJejqo

function maintest () {
        let table;
        let row1;
        let row2;
        let cell0;
        let cell1;
        let header2;
        let autocomplete1;

        table = $('<table>');
        table.attr({"id":"testtable"});


        row1 = $('<tr>');
        table.append(row1);
        header2 = $('<th>').text("Feature/Description");
        row1.append(header2); 

        row2 = $('<tr>');
        table.append(row2);

        cell1 = $('<td>');
        row2.append(cell1); 
        autocomplete1 = $("<input>").attr({"id" : "selector0"});
          cell1.append(autocomplete1);

        $("#mainDiv").append(table);
        $("#selector0").autocomplete();
        $("#selector0").autocomplete( "option", "source", [ "c++", "java", "php", "coldfusion", "javascript", "asp", "ruby" ] );

}
