<div data-role="content">

        <input type="button" value="click to test" onclick="test();"> </input>

            <select id="sel-test">

            </select>

        

        </div>

function test(){

        $("#sel-test").empty();

        for(var i = 1;i <10; i++){

            var opt = "<option value='"+i+"' > " + i + "</option>";

            $("#sel-test").append($(opt));

        }

}

$(document).ready(function() {

for(var i = 1;i <3; i++){

            var opt = "<option value='"+i+"' > " + i + "</option>";

            $("#sel-test").append($(opt));
