保留asp标签值

Question

我有一个asp标签，其文本在网页中动态更改。我有一个按钮。当我单击按钮时，我必须保留标签的文本，而是由于回发而将值设置为初始值。任何人都可以帮我弄清楚如何保留标签的文字。提前致谢。

这是代码

<asp:Label ID="lblRate" runat="server" Text="" ></asp:Label>

这是我要更改标签的地方

<script type="text/javascript">

    function Decide(option) {
                var temp = "";
                document.getElementById('<%=lblRate.ClientID%>').innerText = "";
                if (option == 1) {
                    document.getElementById('<%=Rating1.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating2.ClientID%>').className = "Empty";
                    document.getElementById('<%=Rating3.ClientID%>').className = "Empty";
                    document.getElementById('<%=Rating4.ClientID%>').className = "Empty";
                    document.getElementById('<%=Rating5.ClientID%>').className = "Empty";
                    temp = "1";
                }
                if (option == 2) {
                    document.getElementById('<%=Rating1.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating2.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating3.ClientID%>').className = "Empty";
                    document.getElementById('<%=Rating4.ClientID%>').className = "Empty";
                    document.getElementById('<%=Rating5.ClientID%>').className = "Empty";
                    temp = "2";

                }
                if (option == 3) {
                    document.getElementById('<%=Rating1.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating2.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating3.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating4.ClientID%>').className = "Empty";
                    document.getElementById('<%=Rating5.ClientID%>').className = "Empty";
                    temp = "3";
                }
                if (option == 4) {
                    document.getElementById('<%=Rating1.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating2.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating3.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating4.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating5.ClientID%>').className = "Empty";
                    temp = "4";
                }
                if (option == 5) {
                    document.getElementById('<%=Rating1.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating2.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating3.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating4.ClientID%>').className = "Filled";
                    document.getElementById('<%=Rating5.ClientID%>').className = "Filled";
                    temp = "5";
                }
                document.getElementById('<%=lblRate.ClientID%>').innerText = temp;

                return false;
            }
</script>

这是按钮

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

有人可以帮我吗？
