用户控件后台代码：

调用界面前台：

<asp:Button ID="Button1" runat="server" Text="是否停止闪烁" onclick="Button1_Click" />

调用界面后台：
protected void Page_Load(object sender, EventArgs e)
{
}
protected void OnLoginPress(Object Render, EventArgs e)
{
this.RegisterClientScriptBlock("", "<script>alert(1);</script>");
}
protected void Button1_Click(object sender, EventArgs e)
{
if (!WebUserControl11.IsBroken)
{
WebUserControl11.IsBroken = true;
}
else
{
WebUserControl11.IsBroken = true;
}
if (!WebUserControl12.IsBroken)
{
WebUserControl12.IsBroken = true;
}
else
{
WebUserControl12.IsBroken = true;
}
}
现在的问题是，当只使用一个用户控件，闪烁变色时，是没问题的，多个时会出问题，我想应该是用胡控件中的JS方法名都是一个造成的，就是在用户控件后台注册JS，我就可以控制js的方法名，但是在后台注册的定时器js无效了，想不出来用什么办法来实现自己的功能了。
