What steps should I take to create a .NET/JavaScript login page that works on IE7, Chrome, Mozilla, and Safari browsers?

I am currently dealing with a .NET login page that functions perfectly in Internet Explorer 7. However, my goal is to enhance its compatibility with Chrome, Mozilla, and Safari.

The login code behind looks like this:

Protected Sub btnLogin_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnLogin.Click

{..................

ScriptManager.RegisterStartupScript(Me, Me.GetType(), "test", "login()", True)

........}

Here is the ASPX page code snippet:

function login()

{

    if(document.getElementById("ctl00_Sidebar_Contentplaceholder_Lo1_SaveFlag").value =="Y") 

    {
        window.open("Home.aspx?PlotRef=" + document.all("ctl00_Sidebar_Contentplaceholder_Lo1_SaveFlag").value + "&print=print","",'location=no,fullscreen=no,menubar=no,titlebar=yes,status=yes,toolbar=no,scrollbars=yes,resizable=yes');    

        if(document.getElementById("ctl00_Sidebar_Contentplaceholder_Lo1_hidChangePass").value =="Y") 
        {
            window.open("ChangePass.aspx","ChangePassword","top=50,left=50,height=310,width=725,location=no,menubar=no,status=yes,addressbar=no,toolbar=no,scrollbars=no,fullscreen=no,resizable=no")
        }  

        window.open('','_self','');
        window.close();      
    }
}

Unfortunately, the current setup is not functioning as expected. Despite my attempts at debugging, I have only been able to step through the code behind in debug mode and unable to access the javascript function login() on the ASPX page.

Answer №1

Looking to troubleshoot your JavaScript? Simply insert "debugger;" into your code to create a breakpoint for the browser's debugger (if available, like in Chrome).

Consider using getElementById or getElementsByName instead of document.all. These methods are not only widely supported but also compatible with all browsers.
