Using the method

The syntax of the method is given below:
open (URL, windowName[, windowFeatures])

The URL of the page to open in the new window. This argument could be blank.

A name to be given to the new window. The name can be used to refer this window again.

A string that determines the various window features to be included in the popup window (like status bar, address bar etc)

The following code opens a new browser window with standard features. ("","mywindow"); 

Changing the features of the Popup

You can control the features of the popup using the last argument to the method. The following code opens a window with a status bar and no extra features. ("","mywindow","status=1");

The code below opens a window with toolbar and status bar. ("", "mywindow","status=1,toolbar=1");

The table shows the features and the string tokens you can use:

status The status bar at the bottom of the window.
toolbar The standard browser toolbar, with buttons such as Back and Forward.
location The Location entry field where you enter the URL.
menubar The menu bar of the window
directories The standard browser directory buttons, such as What’s New and What’s Cool
resizable Allow/Disallow the user to resize the window.
scrollbars Enable the scrollbars if the document is bigger than the window
height Specifies the height of the window in pixels. (example: height=’350′)
width Specifies the width of the window in pixels.


The following code opens a window with menu bar. The window is re-sizable and is having 350 pixels width and 250 pixels height. ("","mywindow","menubar=1,resizable=1,width=350,height=250");

Example 1

A window with location bar, status bar, scroll bar and of size 100 X 100 ("", "mywindow","location=1,status=1,scrollbars=1, width=100,height=100");

Example 2

Moving the window to a desired location

You can use the window.moveTo function to move the popup window to a desired location.
The code below shows positioning the popup at a desired location.

function mypopup()
    mywindow ="", "mywindow", "location=1,status=1,scrollbars=1,  width=100,height=100");
    mywindow.moveTo(0, 0);

The code positions the popup on the top left corner of the screen.

Putting it all together

Now we will combine all these information to create the popup windows of different types.
The Code below opens a popup window when you enter the page:

 <title>JavaScript Popup Example 3</title>
<script type="text/javascript">
function poponload()
    testwindow ="", "mywindow", "location=1,status=1,scrollbars=1,width=100,height=100");
    testwindow.moveTo(0, 0);
<body onload="javascript: poponload()">
<h1>JavaScript Popup Example 3</h1>

Notice that the URL is kept blank. This will open a blank window. You can see the code in work in this file:
JavaScript Popup Example 3

Popup On Exit

The following code pops up a window when the user exits a page.

 <title>JavaScript Popup Example 3</title>

<script type="text/javascript">
function exitpop()
    my_window ="", "mywindow1", "status=1,width=350,height=150");
    my_window.document.write('<h1>Popup Test!</h1>');

<body onunload="javascript: exitpop()" >
<h1>JavaScript Popup Example 4</h1>

The code contains an extra line:

my_window.document.write('<h1>Popup Test!</h1>') 

This code displays a line ‘Popup Test!’ in the popup.

The code is available in the file:
JavaScript Popup Example 4

    Good explanation, only wanna to share my experiment in this,,
    my task was to open pdf attachment in new tab, what was happened is when i open the attachment it open in new tab, but when try to open another one it open in the same tab which already hosting the last attachment,,,
    the solution was to add new target name each time you build the form using javascript:
    openit = function(verb, url, data, target) {
    var form = document.createElement(“form”);
    form.action = url;
    form.method = verb; = target+Math.floor(Math.random()*100);
    if (data) {
    for (var key in data) {
    var input = document.createElement(“textarea”); = key;
    input.value = typeof data[key] === “object” ? JSON.stringify(data[key]) : data[key];
    } = ‘none';
