Filter the submit button in Gravity Forms to change the <input type="submit> element to a <button> element. There's an example in the Gravity Forms documentation, but it lacks the proper code to show your custom button text, AND removes important attributes like the onclick that prevents multiple clicks. I was trying to solve that.
// filter the Gravity Forms button type
add_filter("gform_submit_button", "form_submit_button", 10, 2);
function form_submit_button($button, $form){
// The following line is from the Gravity Forms documentation - it doesn't include your custom button text
// return "<button class='button' id='gform_submit_button_{$form["id"]}'>'Submit'</button>";
// This includes your custom button text:
return "<button class='button' id='gform_submit_button_{$form["id"]}'>{$form['button']['text']}</button>";
// Oops this strips important stuff
// This try reveals my use case: I was actually trying to add a pseudo element to the input button
// This leaves the <input> as is, but prepends a span element
add_filter("gform_submit_button", "form_submit_button", 10, 2);
function form_submit_button($button, $form){
return "<span></span>".$button;
// This kinda works for my purpose but is really not ideal
// This is what I settled on
// Change Gravity Forms submit input to a button element
add_filter( 'gform_submit_button', 'form_submit_button', 10, 5 );
function form_submit_button ( $button, $form ){
$button = str_replace( "input", "button", $button );
$button = str_replace( "/", "", $button );
$button .= "{$form['button']['text']}</button>";
return $button;
// It's not perfect - it leaves some inapplicable attributes in the element
// but I can live with that to avoid a whole bunch more str_replace
// and it leaves the important onclick and tab index intact

My personal favorite:

function gf_make_submit_input_into_a_button_element($button_input, $form) {

  //save attribute string to $button_match[1]
  preg_match("/<input([^\/>]*)(\s\/)*>/", $button_input, $button_match);

  //remove value attribute
  $button_atts = str_replace("value='".$form['button']['text']."' ", "", $button_match[1]);

  return '<button '.$button_atts.'>'.$form['button']['text'].'<i class="fa fa-refresh"></i></button>';
add_filter('gform_submit_button', 'gf_make_submit_input_into_a_button_element', 10, 2);

Wonderful filter. That Helps me lot. It really encourages me to explore and customize the filter now. Thank you.

I can't believe the Gravity Forms docs still have the terrible example discussed across this six year old comment thread.
