jquery serialize form and then add another object code example

Example 1: add parameter to serialize javascript

var data = $(this).serializeArray(); // convert form to array
data.push({name: "NonFormValue", value: NonFormValue});
$.ajax({
    type: 'POST',
    url: this.action,
    data: $.param(data),
});

Example 2: jquery ajax send custom data after serialize

var data = $('#myForm').serializeArray();
data.push({name: 'wordlist', value: wordlist});

$.post("page.php", data);
