$(this).serialize() -- How to add a value?
While matt b's answer will work, you can also use .serializeArray() to get an array from the form data, modify it, and use jQuery.param() to convert it to a url-encoded form. This way, jQuery handles the serialisation of your extra data for you.
var data = $(this).serializeArray(); // convert form to arraydata.push({name: "NonFormValue", value: NonFormValue});$.ajax({ type: 'POST', url: this.action, data: $.param(data),});
Instead of
data: $(this).serialize() + '&=NonFormValue' + NonFormValue,you probably want
data: $(this).serialize() + '&NonFormValue=' + NonFormValue,You should be careful to URL-encode the value of NonFormValue if it might contain any special characters.
firstly shouldn't
data: $(this).serialize() + '&=NonFormValue' + NonFormValue,be
data: $(this).serialize() + '&NonFormValue=' + NonFormValue,and secondly you can use
url: this.action + '?NonFormValue=' + NonFormValue,or if the action already contains any parameters
url: this.action + '&NonFormValue=' + NonFormValue,
