Add options dynamically in combo box using Jquery
<p>When i add a new option to a DropDownList using jQuery, it is duplication the values whenever i use that dropdownlist.</p>

<p>For an example : </p>

<pre><code>    var myOptions = { val1 : 'Suganthar', val2 : 'Suganthar2'};

    $.each(myOptions, function(val, text) {
       $('#mySelect').append(new Option(text, val));
    });
</code></pre>

<p>Suganthar, and Suganthar2 are duplicatiing values. </p>

<p>Could anyone give me some idea to rectify this issue</p>
