Ajax load PHP early - php

Question

with submit form havnt problem and i can insert new data .
i have different divs and Textarea that is why i cant use submit input .
i use Ajax, but Ajax load process.php earlier than click that is why get value earlier and insert old data .
How can i load process.php in ajax on click or anyway to get variable after enter new text in textarea with click.

{
var data=$("#user,#user2,#user3,#user4").serialize();
$.ajax({

I think it will solve your problem, if your ajax function calls your PHP before getting value for
data. And add one button with "onclick" event of your function which contains ajax call.
here you can add, "async: false" into your ajax function
function useradd()
{
var data=$("#user,#user2,#user3,#user4").serialize();
$.ajax({
type: "POST",
url: "process.php",
async: false, // add this line ,it will make process synchronous
data: data,
dataType: "html",
});
}
