PO
This is an easy way to send a simple
POST request to a server without
having to use the more complex $
.ajax function. It allows a single callback function to be specified that
will be executed when the request is
complete (and only if the response has
a successful response code). The returned data format can be
specified by the fourth parameter. If
you need to have both error and
success callbacks, you may want to
use $.ajax. $.post is a (simplified)
wrapper function for $.ajax. $.post() returns the XMLHttpRequest
that it creates. In most cases you won't
need that object to manipulate directly,
but it is available if you need to abort
the request manually. Arguments: url String The URL of the page to load. data (Optional) Map, String Key/value pairs or the return value of
the .serialize() function that will be
sent to the server. callback (Optional) Function A function to be executed whenever
the data is loaded successfully. function (data, textStatus) {
  // data could be xmlDoc, jsonObj,
html, text, etc...
  this; // the options for this ajax
request
  // textStatus can be one of:   //   "timeout"
  //   "error"
  //   "notmodified"
  //   "success"
  //   "parsererror"
  // NOTE: Apparently, only "success" is returned when you make
  // an Ajax call in this way. Other
errors silently fail.
  // See above note about using $.ajax.
} type (Optional) String Type of data to be returned to callback
function: "xml", "html", "script",
"json", "jsonp", or "text". $.postJSON = function(url, data,
callback) { $.post(url, data, callback, "json");
}; Code Gets the test.php page contents which
has been returned in json format (<?
php echo json_encode(array
("name"=>"John","time"=>"2pm")); ?
>) $.post("test.php", { func:
"getNameAndTime" },
  function(data){
    alert(data.name); // John
    console.log(data.time); //  2pm
  }, "json");
