 Posted: Mon Mar 13, 2006 11:25 pm Post subject: SmartJax 1.0 |
 |
|
I have released an AJAX library for PHP aptly named SmartJax, soon to have drop-in ready Smarty plugins once I feel the codebase is stable.
The core SmartJax library has no dependency on Smarty, but can easily be integrated into templates. Smarty plugins will help make common uses a snap (vote counting, username lookups, etc.)
SmartJax is loosely based off the My-BIC library by Jim Plush. SmartJax pays close attention to accessability, so when properly programmed your applications will continue to function without xmlhttprequest, or even javascript in many cases.
Please help test, thanks!

GJ, has usual 
I've been working in some plugins but theres a problem.
Is it possible to call more then 1 function at a time ?
I've made a simple event calendar (Blog like) and loads with smartjax all good but i wanted to call a second function to load the events for the day, all onload. And the problem is that it will only load the last function.
Can you help me out ?? |

I haven't tested it, but something like this:
| Code: | function smartjax_hello() {
return sjObj.call("helloworld1", cbHello1) && sjObj.call("helloworld2", cbHello2);
} |
That should execute both ajax functions and return true if they both were successful. |

It seems to overwrite the first callback with the second.
The problem is in the response if i use
| Code: |
self.setTimeout('sjObj.call("helloworld2", cbHello2);',1000);
|
it will work.
I allso find out that this problem is "normal" because im trying to use concurrent requests and the timeout gives enough time to the first callback to finish.

just and idea, did you try:
| Code: | | sjObj.async = false; |
that should force the connection to be synchronous, and wait for the response. |

Nope doesnt solve it. BUT because of that i think i found the problem.
| Code: |
function SMARTJAX(server_url)
this.callBackFunc = "";
|
this is set when creating the object and assumes later on the name the callback function.
| Code: |
SMARTJAX.prototype.call
this.callBackFunc = userCallBackFunc;
|
Because i call it almost the same time, its loses the callback before request returns to the callback.
I tryed to create a new object every time i call the function but doest responds.
Ill try to make some more tweaks ... |

| Did you try creating two separate SmartJax objects, one for each call? |

Now im realy mess up
I dont think you can because of the responseHandler it uses the sjObj.
Maybe the my problem its because the responseHandler uses only 1 object and makes it respond only to the last request. |

Something like this:
| Code: |
var sjObj = new SMARTJAX("/smartjax/smartjax_server.php");
var sjObj2 = new SMARTJAX("/smartjax/smartjax_server.php");
function smartjax_hello() {
return sjObj.call("helloworld1", cbHello1);
}
function smartjax_hello2() {
return sjObj2.call("helloworld2", cbHello2);
}
<a href="" onclick="return(smartjax_hello1() && smartjax_hello2());">click</a>

i've tryed that but it doenst work because of the response Handler only uses one object sjObj.
| Code: |
SMARTJAX.prototype.responseHandler = function()
{
// 4 == "complete"
if (sjObj.req.readyState == 4) {
...
|
sjObj Is the only object that can respond leaving sjObj2 without a response handler. |

I just took a look around my-bic source and found this
| Code: | /**
* This method will allow you to create a "command queue" so ajax requests are sent in order they were fired.
* You will be able to keep your request/responses in order they were sent
*/
XMLHTTP.prototype.add2Queue = function(queryVars, userCallback)
{
var addAjax = new Array();
addAjax['queryVars'] = queryVars;
addAjax['userCallback'] = userCallback;
this.queue.push(addAjax);
} |
It doenst seems you are using this queue. Maybe its a new addition. |

Hi Monte,
example Code from README has a Bug in it:
| Code: |
You will see a basic javascript setup similar to this:
<html>
<head>
<script type="text/javascript" src="/smartjax/smartjax.js"></script>
<script type="text/javascript">
var sjObj = new SMARTJAX("/smartjax/smartjax_server.php");
function smartjax_hello() {
return sjObj.call("helloworld", cbHello);
}
function cbHello(resp) {
document.getElementById('content').innerHTML = resp;
}
</script>
</head>
<body>
<a href="" onclick="return(!smartjax_hello());">click me!</a>
<div id="mystuff"></div>
</body>
</html> |
| Code: | <div id="mystuff"></div>
|
has to be
| Code: | <div id="content"></div>
|
Bye,
Markus |

Just to explain how i am using the smartjax with Smarty and why am i having all these problems.
The background :
I really love how smarty divides all the code in 2 layers (code / template) and because of that i really have difficulties when i only use php.
So i tried to create a structure that can use Ajax with smarty.
Problem :
Why am i only using Ajax for outputting a simple string/array with only a few values?
Why can i output all the data even with HTML?
One of the possible solutions:
Javascript
| Code: |
//Using JSON
function smartjax_template(tpl,div,form) {
url = "&tpl=" + tpl;
if(div) {smartjax_loading(div); url = url + "&div=" + div ;}
if(form) sjObj.getForm(form);
return sjObj.call("template" + url , cbtemplate);
return true;
}
function cbtemplate(resp) {
document.getElementById(resp.div).innerHTML = resp.output;
}
function smartjax_loading(div){
document.getElementById(div).innerHTML = "<div style='width: 100%; text-align:center;padding:2px 2px 2px 2px;'><img src='smartjax/indicator.white.gif' /></div>"
}
|
Plugin
[php:1:0e035592b9]
<?php
/*
* Create this 2 folders.
* <...>php/
* <...>templates/
*
* Then you create 2 files
* <...>php/demo.php - Here you drop all the need "assign" for the tpl (its optional)
* <...>templates/demo.tpl - Here you drop all smarty/html code
*
* This PATH_fs will be the default path structure
*/
define("PATH_fs","/MyDocumentRoot/");
class template
{
var $request;
function template($request_string)
{
$this->request = $request_string;
}
/**
* method to return the contents of xmlhttprequest action
*
* @return mixed
* depending on the format chosen in smartjax:
* TEXT => return a string of text
* XML => return a valid XML document
* JSON (default) => return a string of text OR PHP associative array
*/
function return_response()
{
$resp_["tpl"] = $Pag = $this->request["tpl"];
// In case you dont especify the div id it uses as tpl name as a div id
$resp_["div"] = ($this->request["div"]?$this->request["div"]:$this->request["tpl"]);
if($Pag)
{
if(is_file(PATH_fs."php/".$Pag.".php")) include PATH_fs."php/".$Pag.".php";
if(is_file(PATH_fs."templates/".$Pag.".tpl")) $resp_["output"] = $smarty->fetch($Pag.".tpl");
else $resp_["output"] = "No template Found !!!!";
}
return $resp_;
}
/**
* method to test if xmlhttprequest is authorized
*
* @return boolean true/false
*/
function is_authorized()
{
return true;
}
}
?>
[/php:1:0e035592b9]
This works fine, but because when you make more than 1 consecutive call theres no queue to make the second call wait for the first to finish, you are limited to make only 1 call per event. |
