js如何写单击button按钮后datalist里的label的visible属性变为true

Answer 1

这样写对吗?在vb.net的button_click里应该怎么写?
<script language="javascript" type="text/javascript">
function showHide(label12)
        {
            var dt=document.all.<%=Datalist1.ClientID %>;
 
            if(document.getElementById(lbl).style.display == "none")
            {
                document.getElementById(lbl).style.display = "inline";
            }
            else
            {
                document.getElementById(lbl).style.display = "none"
            }
            return false;
        }</script>
