Javascript 如何使用C#代码获取confirm（）值

我有一个按钮，需要获取

confirm（）

值才能执行数据库操作。例如：点击按钮时，弹出消息确认“是或否”，如果是，则在数据库中进行删除操作，如果否，则清除文本框。如何从Javascript

confirm（）

函数获取返回值。请告知

string jScript;

jScript = "<script> function processConfirm(answer) {if (answer) {return 'Facilitator Deleted';}else {return 'Cancelled';}} var confirmAnswer = confirm('You sure to delete ?');var theAnswer = processConfirm(confirmAnswer);alert(theAnswer);</script>";    
ClientScript.RegisterClientScriptBlock(this.GetType(), "keyClientBlock", jScript);         
/* SqlCommand cmd = new SqlCommand("TrainerFilter", conn);    
cmd.CommandType = CommandType.StoredProcedure;        
cmd.Parameters.Add("@EmployeeID", SqlDbType.Int, 50).Value = TextBox1.Text.Trim();        
cmd.Parameters.Add("@result", SqlDbType.Int, 50).Direction = ParameterDirection.Output;        
conn.Open();        
cmd.ExecuteNonQuery();*/

stringjscript；
jScript=“函数processConfirm（answer）{if（answer）{return'faciliator Deleted'；}else{return'Cancelled'；}}var confirmAnswer=confirm（'确定要删除吗？'）；var theAnswer=processConfirm（confirmAnswer）；alert（theAnswer）；”；
RegisterClientScriptBlock（this.GetType（），“keyClientBlock”，jScript）；
/*SqlCommand cmd=新的SqlCommand（“TrainerFilter”，conn）；
cmd.CommandType=CommandType.storedProcess；
cmd.Parameters.Add（“@EmployeeID”，SqlDbType.Int，50）.Value=TextBox1.Text.Trim（）；
cmd.Parameters.Add（“@result”，SqlDbType.Int，50）.Direction=ParameterDirection.Output；
conn.Open（）；
cmd.ExecuteNonQuery（）*/

您可以将confirm\u procedure（）的值存储在asp:hidden字段中 您可以按如下方式修改脚本： 函数确认_继续（） { var hiddenField=document.getElementById（'hiddenFieldId'）

这有点让人困惑，但假设此确认绑定到按钮单击，您通常会执行以下操作：

<script type="text/javascript">
    processConfirm = function() {
        var result = confirm("Are you sure you want to delete this?");
        if (!result) {
            alert("Cancelled"); //or set a label or whatever
            return false; //cancel postback
        }
        return true; //perform postback
    }
</script>
<asp:Button ID="Button1" runat="server" OnClientClick="return processConfirm();" OnClick="Button1_Click" />

<script type="text/javascript">
    processConfirm = function() {
        var result = confirm("Are you sure you want to delete this?");
        if (!result) {
            alert("Cancelled"); //or set a label or whatever
            return false; //cancel postback
        }
        return true; //perform postback
    }
</script>
<asp:Button ID="Button1" runat="server" OnClientClick="return processConfirm();" OnClick="Button1_Click" />

protected void Button1_Click(object sender, EventArgs e)
{
    //perform the delete logic since because if you reach here
    //you know that the user confirmed

    //throw up an alert when the page is reloaded confirming that the deletion
    //you could also set a label here instead of an alert if you wanted
    Page.ClientScript.RegisterStartupScript(this.GetType(), "confirmDelete", "alert('User was deleted');", true);
}
