在asp.net .cs中创建onclick函数的c#代码

本文关键字：函数 代码 onclick 创建 asp net cs | 更新日期: 2023-09-27 18:05:13

我想做的是在aspx文件中调用aspx.cs中的函数。

JavaScript代码:(为此我试图使c#函数在aspx.cs文件)

function myconfirm() {
    var txt;
    var x = confirm("confirmation!!");
    if (x == true) {
        txt = " Your Request is Submitted!";
    }
    else {
        txt = "Verify and Confirm!";
    }
    document.getElementById("verify").innerHTML = txt;
    return false;
}

c#代码在aspx.cs:(这是我正在尝试和得到一个错误)

namespace TESTING
{
public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
    }
    public void myconfirm(object sender, EventArgs e)
    {
        string x = "confirmation!!";
        string txt;
        if (x == "true")
        {
            txt = "your request is submitted";
        }
        else
        {
            txt = "verify and confirm ";
        }
    }
        public void myconfirm1(object sender, EventArgs e)
        {
            string y="confirmation!!";
            string text;
            if(y=="true")
            {
                text="we are tracking your PRN";
            }
            else{
                text="verify and confirm!!";
            }
    }
}
}

从aspx文件中调用:

<asp: Button ID="Button3" runat="server" Text="SUBMIT" OnClick="myconfirm"></asp: Button>

错误我得到

'myconfirm1' is undefined"

总结它:

  1. 在asp.net文件中定义一个ONCLICK方法。
  2. 从aspx文件中调用

问题发生:

  1. 缺乏在aspx.cs文件中编写c#代码的基本概念。

如果有人能给一个简单的概念，如何编写c#代码在aspx.cs从aspx文件调用

在asp.net .cs中创建onclick函数的c#代码

可以使用下面提到的代码

 <script type = "text/javascript">
    function Confirm() {
        var confirm_value = document.createElement("INPUT");
        confirm_value.type = "hidden";
        confirm_value.name = "confirm_value";
        if (confirm("Do you want to save data?")) {
            confirm_value.value = "Yes";
        } else {
            confirm_value.value = "No";
        }
        document.forms[0].appendChild(confirm_value);
    }
</script>
<asp:Button ID="btnConfirm" runat="server" OnClick = "OnConfirm" Text = "Raise Confirm" OnClientClick = "Confirm()"/>

和你的cs文件看起来像

public void OnConfirm(object sender, EventArgs e)
{
    string confirmValue = Request.Form["confirm_value"];
    if (confirmValue == "Yes")
    {
        this.Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('You clicked YES!')", true);
    }
    else
    {
        this.Page.ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('You clicked NO!')", true);
    }
}

如果我没有错的话。看下面能不能帮你起来

<script type="text/javascript">
        function Confirmation() {
            var rowQuestion = confirm("Are you sure you want to confirm?");
            if (rowQuestion == false) {
                return false;
            }
            return true;
        }
    </script>

和aspx将是:

<asp:Button Text="Confirm Training" OnClientClick="return Confirmation();" ID="btnConfirm"  OnClick="btnConfirm_Click" runat="server" />

首先在javascript的"确认"处确认，然后，只调用后面的btnConfirm_click代码。

如果我没有错，你想消除你的JS代码，并在代码背后文件做逻辑。

public void myconfirm(object sender, EventArgs e)
    {
        string x = "confirmation!!";
        string txt;
        if (x == "true") // your code, I have no idea why you are doing it. You have set x to confirmation so it will never be true in first place. anyways!!
        {
            txt = "your request is submitted";
        }
        else
        {
            txt = "verify and confirm ";
        }
       Verify.Text = txt; // Verify is the label where you want to display your final result.
    }
