推荐答案

<script type = "text/javascript">
    function validate() {

        var txt = document.getElementById("<%=Textbox1.ClientID%>").value;
        if (txt == "") {
            alert("Please enter your name in the textbox before proceeding.");
        }
        else {
            window.location = "default.aspx";
        }
    }
</script>

并在按钮中:

and in the button:

<asp:button id="Button1" runat="server" text="Proceed" onclientclick="validate(); return false" xmlns:asp="#unknown" />

函数调用后返回false阻止回发.

the return false after the function call prevents the postback.
