Submitting a form via JavaScript

It is possible to force a form submission via JavaScript. Let's see how it's done. Suppose we have a form and some button, on click on which we want to submit the form:

public/form.html<form action="/handler/" method="POST">
  <input name="test1">
  <input name="test2">
</form>

<button>submit</button>

We get references to our elements into variables:

public/script.jslet form   = document.querySelector('form');
let button = document.querySelector('button');

Add a click handler to the button:

public/script.jsbutton.addEventListener('click', function(event) {
  
});

And by clicking on the button, we will send the form using the submit method:

public/script.jsbutton.addEventListener('click', function(event) {
  form.submit();
});
