javascript这样为什么就不能调用？
<script language= "javascript " type= "text/javascript ">
function Back()
{
window.history.go(-1);
}
</script>

<asp:Button id= "Button2 " style= "background: url(Normal/tool-bkgd.jpg) repeat-x; BACKGROUND-IMAGE: url(LookOut/cancel.gif); BACKGROUND-REPEAT: no-repeat; " runat= "server " Text= "取消 " Width= "79px " OnClientClick= "return back(); "> </asp:Button>
