Window Confirm Method
You can use the confirm method to ask a user to double check a decision on a web page. When you call this method, the browser will display a dialog box with two choices along the lines of "OK" and "Cancel."
For example, say someone has just clicked a Delete button. You could run the following code:
if (window.confirm("Are you sure you want to delete this item?")) {
// Delete the item
}
The message "Are you sure you want to delete this item?" will appear in the dialog box. If the user clicks "OK", the confirm method will return true and the browser will run the code inside the if statement. If the user clicks "Cancel" or the close button(x) in the top right corner, the method will return false and nothing else will happen. This provides some protection against someone accidentally clicking Delete.
Note: This method takes the focus away from the current window as it prevents the user from accessing other parts of the page until the box is closed.
