After submitting a POST form open a new window showing the result

Let's Break the Ice: Form Submission and Window Behavior Hack

Meet your new friend JavaScript

Let's revamp your friendship with JavaScript for a more controlled approach:

// Someone said JavaScript is the new pen and paper?
const form = document.createElement('form');
form.setAttribute('action', 'MoonLanding');
form.setAttribute('method', 'post');
form.setAttribute('target', '_blank');

// Let's dress our form
const input = document.createElement('input');
input.setAttribute('type', 'text');
input.setAttribute('name', 'Neil_Armstrong');
form.appendChild(input);

document.body.appendChild(form); // 🎵 I believe I can fly 🎵

form.submit(); // Wings ready, let's take off!


Let's Play with Windows (No, Not THAT Windows!)

Marrying new window creation with form submission? JavaScript got you covered!

const form = document.createElement('form');
form.action = 'scoop_the_moon';
form.method = 'post';

const windowName = 'galaxyWindow';
const spaceWindow = window.open('', windowName, 'Fly me to the moon 🌙');

form.target = windowName;

// ...continue setting up & appending inputs to form...

document.body.appendChild(form); // Next stop, the SPACE! 🚀

form.submit(); // Houston, we have IGNITION!

Trick or Treat: Cross-Origin Submissions

Be wary of spooking your users with CORS issues. Ensure your server sends the appropriate CORS headers to make your form submissions smooth.

All Dressed Up: Adding Polish to Window Features

Remember from our user experience seminar:

• Pop-up blockers, much like party poopers, may prevent new windows from opening.
• No kidding, user settings can override target="_blank" behavior.
• Try gussying up window.open with window features. Make a stunning entrance with dimensions, location, and more!

Your Lifeboat: Troubleshooting & Best Practices

Should your ship start sinking (which we totally hope it doesn't!):

• Server as slow as a sloth? It may shift when the new window opens.
• Pesky script blockers and extensions could hinder your JavaScript masterstrokes.
• Perform your quality checks before the form kickoff.
• Use sanitized user data. A stitch in time saves nine!

Supercharge with Asynchronous Operations

Offload data transmission tasks to a sidekick! Use the Fetch API with the power of Promises:

fetch('MoonLanding', {
  method: 'POST',
  body: new FormData(form),
  // More fetch options? Fancy!
}).then(response => {
  window.open('TheMoon', '_blank');
});

Compatibility & Graceful Degradation: BFFs Forever

Ensure your form plays nicely even with JavaScript off by using traditional submission methods. Remember, don't let anyone feel left out at the party.

Don't forget your manners: Validate before you go

Impose quality checkpoints! Implement validation before sparking the launch. An ounce of prevention is worth a pound of cure.
