function LoadValues(){
removeAllOptions(document.drop_list.ddlName);
addOption(document.drop_list.ddlName, " ", "--Select--");

if(If WE want Add Any Condition We can Add Else Simply Skip if Part)
{
addOption(document.drop_list.ddlName,"value1", "Text1");
addOption(document.drop_list.ddlName,"value2", "Text2");
addOption(document.drop_list.ddlName,"value3", "Text3");
}
else if(Condition)
{
addOption(document.drop_list.ddlName,"value1", "Text1");
addOption(document.drop_list.ddlName,"value2", "Text2");
addOption(document.drop_list.ddlName,"value3","Text3");

}

Add options for sources:

<select id="sources"></select>

function showSources(values) {
    var sources = document.getElementById('sources');
    var option;

    var count = values.length;
    if (count == 0) {
        option = document.createElement('option');
        option.text = "N/A";
        sources.appendChild(option);
    }
    else {
        for (var i = 0; i < count; i++) {
            option = document.createElement('option');
            option.text = values[i];
            sources.appendChild(option);
        };
    }
}
