向客户端注入JavaScript代码

 1 protected void Page_Load(object sender, EventArgs e)
 2     {
 3               string a = @"function cao()
 4                     {
 5                         alert('I Love You!');                    
 6                     }
 7                     ";
 8         ScriptManager.RegisterClientScriptBlock(Button1,typeof(Button),"cao",a,true);
 9         Button1.Attributes.Add("onclick","javascript:cao()");
    }

页面代码:

 <asp:Button ID="Button1" runat="server" Text="Button" />
