These actions can include clicking on a button, submitting a form, or entering text into a field. By using DOM events, you can add additional functionality to your Contact Form 7 forms and customize the behavior of your forms based on user actions.

Contact Form 7 provides a range of DOM events that you can use to customize your forms. These events include:

wpcf7submit: This event is triggered when a user submits a form. You can use this event to perform actions after the form is submitted, such as displaying a message or redirecting the user to a different page.
wpcf7invalid: This event is triggered when a user submits a form with invalid data. You can use this event to display error messages or highlight fields with invalid data.
wpcf7mailsent: This event is triggered after a form is submitted and the email has been sent. You can use this event to perform actions after the email has been sent, such as displaying a confirmation message.

if(wpcf7Elm){
  wpcf7Elm.addEventListener( 'wpcf7mailsent', function( event ) {
   const name = event.detail.inputs[0].value;
   const email = event.detail.inputs[1].value;
   const phone = event.detail.inputs[2].value;
   const hash = event.detail.apiResponse.posted_data_hash;
   window.location.href=`/thank-you?nam=${name}&email=${email}&phone=${phone}&hash=${hash}`;
