Javascript 如何使用两个确认对话框？

我有一个链接按钮，在单击和确认对话框时显示确认对话框，我必须在数据库中搜索，如果找到值，则应再次显示确认对话框，在确认对话框后，再次必须执行一些搜索任务。为了更好地理解，我附上了流程图

Aspx页

 <script language="javascript" type="text/javascript">
        function confirm_payslip() {
                            var res = confirm("Are you sure to upload current month payslip data");
                            if (res) {
                                //return true;
                                document.getElementById("HiddenField1").value = "1";
                               var myName = <%=this.firstName%>;
                               if(myName==1)
                               {
                               var result = confirm("Payslip Already Uploaded. Do you want to replace it?");
                               if(result)
                               {
                               document.getElementById("HiddenField1").value = "2";
                               }
                               else
                               {
                                document.getElementById("HiddenField1").value = "0";
                                return false;
                               }
                               }
                            }
                            else {

                                document.getElementById("HiddenField1").value = "0";
                                return false;
                            }
                            return true;                         //document.getElementById("ctl00_ContentPlaceHolder1_div_PayTax").className = "loading"; 
                        }
        </script>
<asp:LinkButton ID="lbtn_payslip" runat="server" OnClientClick="confirm_payslip();" OnClick="lbtn_payslip_Click">Upload PaySlip Data</asp:LinkButton>
<asp:HiddenField ID="HiddenField1" runat="server" />

问题是第二个对话框以偶数运行，如第二次单击、第四次单击等。那么如何完成上述任务呢？

本演示可能会有所帮助？

我的方法有点不同，但它会让你达到你想要的

政务司司长网页：

protected void LinkButton1_Click(object sender, EventArgs e)
    {
        if (HiddenField1.Value.Trim() == "0")
        {
            return;
        }
        qry = "select count(*) from tbl_payslip_prn_t";
        dt = con.Execute(qry);
        if (dt.Rows.Count > 0)
        {
            ClientScript.RegisterStartupScript(typeof(Page), "exampleScript", "if(confirm(\"Payslip Already Uploaded. Do you want to replace it?\")){ document.getElementById('Button1').click(); }", true);
        }
        else
        {
            //Do Some task
        }
    }  
    protected void Button1_Click(object sender, EventArgs e)
    {
        //Do Some Task    
    }

aspx页面：

<script type="text/javascript">
        function confirm_payslip() {
            var res = confirm("Are you sure to upload current month payslip data");
            if (res) {
                //return true;
                document.getElementById("HiddenField1").value = "1";
            }
            else {

                document.getElementById("HiddenField1").value = "0";
                return;
            }
        }
    </script>
 <div>
        <asp:LinkButton ID="LinkButton1" runat="server" OnClientClick="confirm_payslip();" onclick="LinkButton1_Click">LinkButton</asp:LinkButton>

    </div>
    <div style="display:none">
     <asp:Button ID="Button1" runat="server" Text="Button" 
            onclick="Button1_Click" />
     <asp:HiddenField ID="HiddenField1" runat="server" />
    </div>

功能确认_工资单（）{
var res=confirm（“您确定要上传当月工资单数据吗”）；
如果（res）{
//返回true；
document.getElementById（“HiddenField1”）.value=“1”；
}
否则{
document.getElementById（“HiddenField1”）.value=“0”；
返回；
}
}
链接按钮

在您的aspx上添加一个隐藏的asp:按钮，并将一个事件处理程序附加到该按钮上，然后在单击“确认”按钮上的“是”后编写您希望执行的代码

ClientScript.RegisterStartupScript(typeof(Page), "MyScript", "if(confirm(\"Payslip Already Uploaded. Do you want to replace it?\")){ document.getElementById('Button1').click(); }", true);

安静有用，但这不是我想要的。由于我必须在确认第一个对话框后从数据库中获取数据，并且代表第二个对话框，我建议使用webparts，因为在客户端（JS）和服务器（C#）端分离逻辑并不是编码的最佳方式，因为它变得难以管理和维护。

<script type="text/javascript">
        function confirm_payslip() {
            var res = confirm("Are you sure to upload current month payslip data");
            if (res) {
                //return true;
                document.getElementById("HiddenField1").value = "1";
            }
            else {

                document.getElementById("HiddenField1").value = "0";
                return;
            }
        }
    </script>
 <div>
        <asp:LinkButton ID="LinkButton1" runat="server" OnClientClick="confirm_payslip();" onclick="LinkButton1_Click">LinkButton</asp:LinkButton>

    </div>
    <div style="display:none">
     <asp:Button ID="Button1" runat="server" Text="Button" 
            onclick="Button1_Click" />
     <asp:HiddenField ID="HiddenField1" runat="server" />
    </div>

ClientScript.RegisterStartupScript(typeof(Page), "MyScript", "if(confirm(\"Payslip Already Uploaded. Do you want to replace it?\")){ document.getElementById('Button1').click(); }", true);
