Definition of jQuery window

jQuery window object represents an open window in the browser. The window object is automatically created by the browser. Suppose our documents contain multiple frames, then the browser creates one window object for the HTML document and creates additional window objects for each frame. The window object is not the object of jQuery or JavaScript, it is the object of the browser. Almost all browsers support a window object, but there is no public standard that applies to the window object.

Examples

Example of jQuery window object to use properties and methods. Next, we write the HTML code to understand the jQuery window object more clearly with the following example, where we use properties and methods of the window object, as below –

Code:

<!doctype html>
<html lang = "en">
<head>
<meta charset="utf-8">
<title> This is an example for jQuery window object </title>
<script src = "https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js">
</script>
</head>
<script>
var nwindow;
function fun_open() {
nwindow = window.open("", "newWindow", "width=500, height=500");
nwindow.document.write("<h3>This is a new window.</h3>");
}
function property_apply() {
if (!nwindow) {
document.getElementById("text").innerHTML = "Not opened 'newWindow'.";
} else {
if (nwindow.closed) {
document.getElementById("text").innerHTML = "Closed 'newWindow'.";
} else {
document.getElementById("text").innerHTML = " Not closed 'newWindow'..";
}
}
}
function get_parent_window()
{
nwindow.opener.document.write("<p>This is the window which create the new window.</p>");
}
function fun_close() {
if (nwindow) {
nwindow.close();
}
}
</script>
</head>
<body>
<p> Example for the jQuery window properties and methods</p>
<ul>
<li>
<button onclick="fun_open()">Call function to create window</button></li>
<br><br>
<li><button onclick="property_apply()"> Call function to check wethere window open or close</button></li>
<br><br>
<div id="text"></div>
<br><br>
<li><button onclick="fun_close">Call function to close window</button></li>
<br><br>
<li> <button onclick="get_parent_window()">Call function to get parent window</button></li>
<br><br>
</body>
</html>

Output:

Once we click on the “Call function to create window” Button, the output is:

And once we click on the “Call function to close window” button, the new created window get closed.

Next when we click on the “Call function to check whether window open or close” button, the output is –

Next when we click on the “Call function to get parent window” button, which opens a new window and display as –

The above program it demonstrating the use of some of the window properties and methods. As above in the code, it is used the document and opener properties and the open(), close() functions.

Conclusion
