How to Detect Window.print() Finish For Iframe?

To detect when the window.print() function has finished printing for an iframe, you can utilize the onafterprint event listener. This event is fired after the print dialog box is closed, indicating that the printing process has been completed. You can add an event listener for onafterprint to the iframe element, and perform any necessary actions or checks once the printing process has finished. This allows you to track when the print task has been completed successfully.

What is the most accurate indicator that window.print() has completed printing?

The most accurate indicator that window.print() has completed printing is to listen for the "afterprint" event. This event is triggered by the browser after the print dialog has been closed, indicating that the printing process has completed. You can add an event listener for the "afterprint" event to know when the printing process has finished successfully.

How to receive a notification once window.print() has finished running?

Unfortunately, there is no built-in mechanism in JavaScript to receive a notification once the window.print() function has finished running.

One possible workaround is to use the afterprint event, which is triggered after the print dialog has been shown and the user selects the print option. You can add an event listener for this event and trigger a custom function to simulate a notification once printing is complete.

Here's an example code snippet that demonstrates this approach:

1
2
3
4

window.addEventListener('afterprint', function() {
    alert('Printing has completed successfully!');
});
window.print();

Keep in mind that the afterprint event may not be supported in all browsers, so it's important to test this functionality across different browsers to ensure compatibility.

What is a dependable method for detecting when window.print() is done?

One way to detect when window.print() is done is by using the window.onafterprint event. This event is triggered after the print dialog is closed and the document has been sent to the printer. You can listen for this event in your code and perform any necessary actions once the printing process is complete.

Here is an example of how you can use the window.onafterprint event to detect when window.print() is done:

1
2
3
4

window.onafterprint = function() {
  console.log('Printing completed');
  // Perform additional actions here
};

By using the onafterprint event, you can reliably detect when the printing process initiated by window.print() has finished.

How to ensure that window.print() has finished for an iframe?

You can use the onafterprint event to detect when the window.print() function has finished printing for an iframe. Here's an example of how you can achieve this using JavaScript:

1. Add an event listener to the onafterprint event for the iframe element:

1
2
3
4
5
6

var iframe = document.getElementById('your-iframe-id');

iframe.addEventListener('onafterprint', function() {
   // The window.print() function has finished printing for the iframe
   console.log('Printing finished for iframe');
});

1. Call the window.print() function on the iframe:

1

iframe.contentWindow.window.print();

By adding the event listener, you can detect when the window.print() function has finished printing for the iframe and perform any necessary actions afterwards.
