Here's my code:
this.ajax = new Ajax.Request(this.url, {
method: 'get',
parameters: { 'timestamp' : this.timestamp },
onSuccess: function(transport) {
// handle the server response
var response = transport.responseText.evalJSON();
this.comet.timestamp = response['timestamp'];
this.comet.handleResponse(response);
this.comet.noerror = true;
},
onComplete: function(transport) {
// send a new ajax request when this request is finished
if (!this.comet.noerror)
// if a connection problem occurs, try to reconnect each 5 seconds
setTimeout(function(){ comet.connect() }, 5000);
else
this.comet.connect();
this.comet.noerror = false;
}
});
I mainly want to know about the onComplete
function, that's what I'm pondering over.
One such function is .ajax
. The documentation is quite exhaustive: jQuery .ajax function.
An example of onSuccess
and onComplete
-like functionality might be something like this...
$.ajax({
url: "test.php",
type: "post",
data: values,
success: function() {
alert("success");
},
error: function() {
alert("failure");
},
complete: function() {
alert("both success and error have been checked, request finished!");
}
});
There are also individual .post
and .get
functions, but they are best avoided as they make assumptions about the response, and that can lead to unintended failures.
