OnClientClick和OnClick

<head runat="server">
    <title>无标题页</title>
    <script language="javascript">
    function check()
    {
        var email = document.getElementById('TextBox1');
        var pwd = document.getElementById('TextBox2');
        if (email.value=="" || pwd.value=="")
        {
            alert("请填写完整内容");
            return false;
        }
        else
        {
            var mailStr = /(("w)+)@(("w)+).[cc|com|net|org|tv|cn]/ig;
            if (!mailStr.exec(email.value))
            {
                alert('Email地址书写不正确!"n请您重新输入!');
                email.value = '';
                email.focus();
                return false;
            }
        }
    }
    </script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> 
        <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return check();" OnClick="Button1_Click1" /></div>
    </form>

</body>

先执行客户端的javascript函数，页面回送以后再执行服务器端的方法
