Actually this is little bit advanced technique, you need to have a good idea regarding jQuery. Basically I had to add a spinner just before the submit button of the form, so that viewers get idea that the form submission is working and they don’t get confused.
Here is the JQuery Code I used:
jQuery(document).ready(function(){
jQuery( 'form' ).on( 'click', 'SUBMIT BUTTON ID OR CLASS', function (e) {
var formElement = document.querySelector('FORM ID OR CLASS');
if(formElement.reportValidity()){
jQuery('CLASS OR ID OF DIV AFTER WHICH THE SPINNER WILL ADD').after('<img style="width:70px;" src="YOUR SPINNER URL">');
}
});
});
Please feel free to ask question in the comments section if you have any question regarding the code and i will describe you.
