Using the window.open method by Gaurav Arora

The syntax of the window.open method is given below:

open (URL, windowName[, windowFeatures])

URL
This is the URL of the page which open in the new window. It could be blank.

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

windowFeatures
It contains the various window features for the popup window i.e. status bar, address bar etc

The following lines of code, open a new browser window with standard features :

window.open ("http://interview.msdotnetheaven.com","MsDn Interview Questions");

 

Changing the features of the Popup

By using some stuff we can control the features of the popup.

The following code opens a window with a status bar and no extra features:

window.open ("http://interview.msdotnetheaven.com","MsDn Interview Questions","status=1");

The code below opens a window with toolbar and status bar :

window.open ("http://interview.msdotnetheaven.com","MsDn Interview Questions","status=1,toolbar=1");

The following is the table tells the features :

status The status bar.
toolbar The standard browser toolbar.
location The URL Location entry field.
menubar The menu bar of the window
directories The standard browser directory buttons.
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.
width Specifies the width of the window in pixels.

 

Example :
The Code below opens a popup window when you enter the page:

<html>
<head>
 <title>Open Blank Popup WIndow </title>
</head>
 <SCRIPT language="JavaScript">
function openBlank()
{
testwindow= window.open ("", "mywindow",
    "location=1,status=1,scrollbars=1,width=100,height=100");
testwindow.moveTo(0,0);
}
</SCRIPT>
 <body onload="javascript: openBlank()">
