javascript - What happens with data received by the server using ajax? -


one.php:

html:

<button value="testvalue" name="foo">click</button>

javascript:

var keyvals = {foo:"bar"}         $(function() {             $("button").click(function() {                 $.ajax({                     type:"post",                     url:"two.php",                     data: keyvals,                     success: function() {                         $("#center").append("<p>data transfer succeeded! </p>");                     }                 });             });         });

now, happens data? how can use in two.php? want save in file/database, why not save directly one.php? i've tried following:

two.php:

    <?php         var_dump($_request);     ?>

comes out empty. happens data sent one.php? how can use it?

strangely enough, i've looked @ every similar question find, , none of them answered properly, , of them downvoted. what's wrong question?

send data -

data: { value : $(this).val() },

on php access -

$value = $_post["value"];
