How can I open a new window through javascript when popup is blocked in IE and Firefox.

Below is the code:

<%@ Page language="c#" AutoEventWireup="false" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" > 

<html>
  <head>
    <title>SessionRedirect</title>
    <meta name="GENERATOR" Content="Microsoft Visual Studio .NET 7.1">
    <meta name="CODE_LANGUAGE" Content="C#">
    <meta name=vs_defaultClientScript content="JavaScript">
    <meta name=vs_targetSchema content="http://schemas.microsoft.com/intellisense/ie5">
  </head>
  <body MS_POSITIONING="GridLayout">

    <form method="post" name="frmRedirect">   
        <input type="hidden" name="email" value="<%=Session["Email"].ToString() %>" />
        <input type="hidden" name="pass" value="<%= Session["PWD"].ToString() %>" />
        <input type="hidden" name="User" value="<%= Session["User"].ToString() %>" />
    </form>

<script type="text/javascript"> 

    if(frmRedirect.User.value == "P")
    {
        window.open("", "Partner", "height=650,width=1075,left=100,top=100,status=1,scrollbars=1,location=1,toolbar=1;resizable=1");
        frmRedirect.target="Partner";       
        frmRedirect.action = "http://pli.cmsstag/partnerzone/index.aspx";
        document.frmRedirect.submit(); 
        location.replace("index.aspx");
    }
    else
    {
        window.open("", "Student", "height=650,width=1075,left=100,top=100,status=1,scrollbars=1,location=1,toolbar=1;resizable=1");
        frmRedirect.target="Student";
        frmRedirect.action = "http://pli.cmsstag/studentzone/index.aspx";
        document.frmRedirect.submit(); 
        location.replace("index.aspx");
    }   

</script>

<%
    Session.Remove("registration");
    Session.Remove("User");
    Session.Remove("UserId");
    Session.Remove("UserLoggedIn");
    Session.Remove("AgentCode");
    Session.Abandon();

回答1:

Pop ups created by window.open can get blocked by pop up blockers. You can add a new div layer that acts like a pop up to solve this.

Javascript Modal Dialog

Some of the problems with div pop ups are

. dropdown lists come in the way of these pop ups.

. on window resize the position has to be changed

etc

In the above page many of the issues with a div pop up has been solved.

回答2:

Popup blockers only block unintended popups.

If your popup is displayed while handling a click event from the user, your popup might not be blocked by the popup blocker.

So as long as your user clicks on a button or a link to open the popup, it will be ok with current popup blockers.

回答3:

The easiest way is to tie it to a button click. No added code required, and it's designed to prevent people from doing shady things (like popups on close, or huge numbers of popups).

jQuery, as mentioned, could get you a 'popup' or a modal dialog, but would not serve very well to open a 'new window' as the OP requested.

回答4:

Code for the div idea:

<div style="display:none; position: absolute;z-index:99" id="display">you div info here</div>


<script langauge="javascript">

function showPopup ()
{
  var div = document.getElementById("display");

  div.style.display = "inline";

  div.style.top = 20;
  div.style.left = 233;


}

</script>

try this,

$('#myButton').click(function () {
    var redirectWindow = window.open('http://google.com', '_blank');
    redirectWindow.location;
});
