用onchange替换onclick。这里试试这个代码：

<select name="Database Type" onchange="fillData()" id="sel_value"> 
     <option value="DB2">DB2</option> 
     <option value="Derby">Derby</option> 
     <option value="Hypersonic">Hypersonic</option> 
     <option value="Ingres">Ingres</option> 
     <option value="MySQL">MySQL</option> 
     <option value="Oracle">Oracle</option> 
     <option value="P6Spy">P6Spy</option> 
     <option value="PostgreSQL">PostgreSQL</option> 
     <option value="SQL Server">SQL Server</option> 
     <option value="Sybase">Sybase</option> 
</select> 

的Javascript：

function fillData(){ 
    alert($('#sel_value').val()); 
}
