Cannot hook to javascript alert message

How do get the handle of the javascript alert window?

I tried with the following code in LTAF but I'm not successful here. I'm not sure how to access the alert window and see whether it is showing the message that I want to show.

HtmlPage popup = currentPage.GetPopupPage(1,20);

Thanks

Re: Cannot hook to javascript alert message

Hi,

Here is an example:

JsAlert.aspx:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="JsAlert.aspx.cs" Inherits="JsAlert" %>


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">


<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
        <asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
    </div>
    </form>
</body>
</html>

JsAlert.aspx.cs:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

public partial class JsAlert : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        ShowMessage(Page, "Hi");
    }
    public static void ShowMessage(Page aPage, string aMessage)
    {
        aPage.RegisterStartupScript("AlertMsg", "<script language='javascript'> alert('" + aMessage + "'); </script>");
    }
}

wish it helps

Hello Murali, handling of alerts currently is only supported in response to a Click action. You can see an example on the sample website that comes with the code plex download. I copy the test below that shows the API.

[WebTestMethod]
    public void HandleConfirmPopUp()
    {
        HtmlPage page = new HtmlPage("ScriptSamples.aspx");

        // click on the button and cancel the confirm
        page.Elements.Find("ButtonWithConfirm").Click(new CommandParameters(WaitFor.None,PopupAction.ConfirmCancel));
        Assert.AreEqual("", page.Elements.Find("Label1").GetInnerText());

        // click on the button and accept the confirm
        page.Elements.Find("ButtonWithConfirm").Click(new CommandParameters(WaitFor.Postback, PopupAction.ConfirmOK));
        Assert.AreEqual("The Button was clicked.", page.Elements.Find("Label1").GetInnerText());
    }

Thanks Federico. I had a look at the sample site. It looks like the Assert is based on what the server returns.

In my case, the validation happens at the client. For e.g. I need to check whether mandatory fields have been provided and I provide an alert message (which differs based on what fields have been populated). Is it not possible for me to grab that alert and Assert on the message?

Thanks

Re: Cannot hook to javascript alert message

I see what you are saying, this is a little know feature, but when you issue a Click command using the CommandParameters overload, the text of the alert will be captured and available through the PopupText property. Here is a sample:

<div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> // click on the button, cancel the confirm and verify alert text</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> CommandParameters commandParams = new CommandParameters(WaitFor.None, PopupAction.ConfirmCancel);</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> page.Elements.Find("ButtonWithConfirm").Click(commandParams);</div> <div style="position: absolute; left: -10000px; top: 0px; width: 1px; height: 1px; overflow-x: hidden; overflow-y: hidden;" id="_mcePaste"> Assert.AreEqual("string from the alert", commandParams.PopupText);</div>

// click on the button, cancel the confirm and verify alert text

CommandParameters commandParams = new CommandParameters(WaitFor.None, PopupAction.ConfirmCancel);

page.Elements.Find("ButtonWithConfirm").Click(commandParams);

Assert.AreEqual("string from the alert", commandParams.PopupText);

Hope this helps,

Federico
