 相关JS:

    <script type="text/javascript" language="javascript">
    
function SearchChange()
    {
        
var ddl = document.getElementById("DropDownList1")   
        
var index = ddl.selectedIndex;   
            
        
var Value = ddl.options[index].value;   
        
var Text = ddl.options[index].text;
        
        alert(Value);
    }
