            } else {
                return false;

<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return one();" 
            onclick="Button1_Click" />
    </div>
    </form>
</body>
</html>
        protected void Button1_Click(object sender, EventArgs e)
        {
            Response.Write("This is Behind Code");
        }

asp.net控件的onClientClick return 执行js函数,true通过则进入后端方法，false则不通过。
