<!--INTRODUCTION-->
<b>clsJSPHP</b> is a <a href="http://www.php.net">PHP</a> class that allows you to create
richer web applications. That means that you can send asyncron/syncron
requests to your server without reloading the page.
<br /><br />
For now clsJSPHP is in an <b>alpha-phase</b>. So test it and send me feedback ([email protected])!
<!--API--><br /><br />
<h2>Installation</h2>
Make a reference to the core javascript in the header of your
html document:
<code>
<b>code:</b><br /><br />
<?=htmlentities('<script src="[PATH_TO_clsJSPHP.php]?jsphp=[PATH_TO_clsJSPHP.php]" language="JavaScript"></script>');?>
</code><br />
and you are ready to start!<br /><br />
<h2>Usage</h2>
clsJSPHP doesn't register any php functions that you can call with javascript
on the client-side. clsJSPHP request a php-file and handle the returned output.
<h3>How should the code look like?</h3><br />
<h3>THE HTML-SIDE:</h3>
<code>
<b>code:</b><br /><br />
<b>client-side:</b><br />
<pre>
<?=str_replace(array('[b]','[/b]'),array('<b style="color:red;">','</b>'),htmlentities('
<html>
<head>
[b]<script src="[PATH_TO_clsJSPHP]?jsphp=[PATH_TO_clsJSPHP]" language="JavaScript"></script>[/b]
</head>
<body>
<input type="button" onClick="[b]jsphp_exec(\'[PATH_2_PHPFILE]\',\'[PARAMETER]\',[ASYNC=true/false]);[/b]" />
</body>
</html>
'));?>
</pre>
</code><br />
<i>[PATH_TO_clsJSPHP]</i><br />relative Path to clsJSPHP (e.g. './clsJSPHP.php' if it is in the same folder)<br /><br />
<i>[PATH_2_PHPFILE]</i><br />relative Path to the clsJSPHP.php class (e.g. './ajaxhandle/ajaxinclude.php')<br /><br />
<i>[PARAMETER]</i><br />The parameters you want to tranfer to the php file (e.g. 'id=1&user=frank')<br /><br />
<i>[ASYNC]</i><br />Parameter if you want to request the php file asyncron or not (default is true)<br /><br />
<br />
<h3>THE SERVER-SIDE:</h3>
<code>
<b>code:</b><br /><br />
<b>server-side (the php file you are calling):</b><br />
<pre>
<?
//Make sure this file is called by clsJSPHP
if(!defined('JSPHP_INC')) die('YOU ARE NOT ALLOWED TO ACCESS THIS FILE DIRECTLY');
<b>$jsphp</b>->addAlert('This is a test');
<b>$jsphp</b>->output();
/*
To get transfered parameters use $_POST or $_REQUEST !!
Parameters are send with POST because you can transfer more data with it.
*/
?>
</pre>
</code><br />
And that's it. After pressing the button (html-side) a message ('This is a test') will appear.
Quite simple right!?
<br /><br />
<h3>You have the following methods to manipulate the HTML-Side from the requested php file:</h3>
<pre>
<b>$jsphp</b>->setStyle($targetid,$attribute,$style);
<b>$jsphp</b>->setAttributte($targetid,$attribute,$value);
<b>$jsphp</b>->innerHTML($targetid,$text);
<b>$jsphp</b>->addAlert($msg);
</pre>
<h3>Quick javascript functions on the html-side</h3>
<pre>
<b>jsphp_gcontent(url,prm)</b>
returns output as string from requested php file (url)
<b>jsphp_shtml(id,url,prm,async)</b>
set inner html of an element (with the given id) with the output from requested php file (url)
<b>jsphp_svalue(id,url,prm,async)</b>
set value of an element (e.g. input-field with the given id) with the output from requested php file (url)
</pre>
More features will be included in the future.
<!--EXAMPLES--><br /><br />
<h2>Examples</h2>
<h3>Example 1</h3>
This example shows how to get just raw php output:
<div class="example">
<input type="button" onClick="alert(jsphp_gcontent('ajaxinclude.php','prm1=1',false));" value="hello world" />
</div>
<code>
<b>code:</b><br /><br />
<?=htmlentities("alert(jsphp_gcontent('ajaxinclude.php','prm1=1'));");?>
</code><hr />
<h3>Example 2</h3>
This example shows how to set an input-value with php output:
<div class="example">
<input type="text" id="txtval" />
<input type="button" onClick="jsphp_svalue('txtval','ajaxinclude.php','prm2=1&index=2');" value="Set value" />
</div>
<code>
<b>code:</b><br /><br />
<?=htmlentities("jsphp_svalue('txtval','ajaxinclude.php','prm2=1&index=2');");?>
</code><hr />
<h3>Example 3</h3>
This example shows how to set inner html of an element with php output:
<div class="example">
<div id="cdiv" style="border:1px #ccc solid;background:#eee;width:300px;height:200px;overflow:auto;padding:4px;">click button!</div>
<br />
<input type="button" onClick="jsphp_shtml('cdiv','ajaxinclude.php','prm3=1');" value="Load data" />
</div>
<code>
<b>code:</b><br /><br />
<?=htmlentities("jsphp_shtml('cdiv','ajaxinclude.php','prm3=1');");?>
</code><hr />
<h3>Example 4</h3>
This example shows how to modify html with requested php file:
<div class="example">
<div id="cmdiv" style="border:1px #ccc solid;background:#eee;width:300px;padding:4px;">Sample text...</div>
<br />
<input type="button" onClick="jsphp_exec('ajaxinclude.php','prm4=1');" value="Send request" />
</div>
<code>
<b>code:</b><br /><br />
<?=htmlentities("jsphp_exec('ajaxinclude.php','prm4=1');");?>
<pre>
<b>ajaxinclude.php:</b>
if(isset($_REQUEST['prm4'])){
$jsphp->addAlert('textcolor will be modified...');
$jsphp->setStyle('cmdiv','color','red');
$jsphp->output();
}
</pre>
