<script language="javascript" type="text/javascript">
function resize()
{
//alert("ok");
var e = document.GetElementById("ImageEdit");
e.style.width = "500px";
}
</script>
<asp:Image ID="ImageEdit" runat="server" BorderWidth="4" Width="120px" Height="120px" name="Image1" /></td></tr>
<input id="Button1" type="button" value="button" onclick="resize();" />
ImageEdit
幅が変わらないのはなぜですか?
