If you want to send some extra data (key/values) to the server while submitting an HTML form using jQuery Ajax function then its can be achieved by appending your query string data parameter,
Code Snippet$.ajax({
url: "../server-url.php",
type: "POST",
async: true,
cache: false,
data: $('form').serialize() + "&key1="+ value1 + "&key2=" +
document.getElementById("field").value,
success : function(val){
alert("Success!");
}
});After $('form').serialize() I have just appended the data as query String.
