i'm sending multiple ajax.request instances when i search for
something when the 'keypress' event is fired; this is not a problem
unless sometimes some ajax.request's don't came back in the same order
that they was sended... in some cases earlier requests came back after
late requests and that can be anoying to the user... i was thinking in
atach to the request a timestamp and in the handler function wait for
the last timestamp in the last request and dismiss the others; i don't
know if there exists a more elegant way to do this...i was thinking to
send the timestamp in the request and send it back from the server and
check it that way but i would like to do in the client side only...
example:
$('textbox').observe('keypress', this.send_request.bind(this));
...
this.send_request = function() {
options.onComplete = this.ajax_handler; // Handler function for the
request...
var current_date = new Date();
timestamp = current_date.getTime();
options.timestamp=timestamp; // Timestamp in the Ajax options for
identify it in the handler...
this.expected_timestamp=timestamp;
this.ajax_object = new Ajax.Request('sql.php', options); // Generate
Request...
}
this.ajax_handler = function(response) {
// Do anything i have to do here...
// There i need to know the timestamp asociated by the ajax object
that triggered this
// function in order to use it only if is the last request and dismiss
others
// ....
}
thanks in advance for the help... ( and excuse my poor english ...)
