一般不那样做,直接有按钮的事件
onclientclick="return confirm('确认要删除吗？');"

Answer 3

HTML code<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return confirmDel();" OnClick="Button1_Click"></asp:Button>
JScript code
    <script type="text/javascript">
        function confirmDel() {
            returnwindow.confirm("You will delete it.Do you want to continue?");
        }
    </script>

Answer 4

按照你你说的方法要这样写        Response.Write(@"<script defer> 
                        function confirmDelete() {
                            var result = confirm('是否删除？'); 
                            if (!result) {
                                alert('del')
                            } else {
                                alert('do not del')
                            } 
                        } 
                        confirmDelete();
                        </script> ");
