how to submit a form by calling jquery function code example

Example 1: jQuery AJAX form submit

// jQuery ajax form submit example, runs when form is submitted
$("#myFormID").submit(function(e) {
    e.preventDefault(); // prevent actual form submit
    var form = $(this);
    var url = form.attr('action'); //get submit url [replace url here if desired]
    $.ajax({
         type: "POST",
         url: url,
         data: form.serialize(), // serializes form input
         success: function(data){
             console.log(data);
         }
    });
});

Example 2: jquery on form submit call function

$(document).ready(function() {
  $("your form selector here").submit(function() {


    // do the extra stuff here
    $.ajax({
     type: "POST",
      url: "mail.php",
      data: $(this).serialize(),
      success: function() {
        $('.simple-sucess').fadeIn(100).show();
        $('.contact_form').fadeOut(100).hide();
        $('.simple_error').fadeOut(100).hide();

       }
    })

  })
})
