JavaScript: Print the contents of the current window

JavaScript Basic: Exercise-2 with Solution

Print Current Window Contents

Write a JavaScript program to print the current window contents.

This JavaScript program defines a function that uses the window.print() method to print the contents of the current browser window. When the function is called, it triggers the print dialog, allowing the user to print the current webpage.

Sample Solution:

JavaScript Code:

// Define a function named print_current_page
function print_current_page() {
    // Call the window.print() method to initiate the printing of the current page
    window.print();
} 

Output:

Click the button to print the current page.
