<h3> <big style="font-weight: bold;">Some Prerequisits</big></h3>
<br>
<ol>
<big> </big><li><big>PHP 4 or later (on server).</big></li>
<big> </big><li><big>Javascript enabled browser (I tested it on
Firefox1.0 + and IE
5.5+).</big></li>
<big></big>
</ol>
<big> I may add other prerequisits later.</big><br>
<br>
<h3><big>Simple Usage:</big></h3>
<big> <br>
1. In HTML file include the rspa.js <br>
<br>
<big><span style="color: rgb(204, 51, 204);">
<small><script </small></span><small><span style="color: rgb(51, 204, 0);">language</span>=<span style="color: rgb(51, 51, 255);">"JavaScript"</span> <span style="color: rgb(51, 204, 0);">type</span>=<span style="color: rgb(51, 51, 255);">"text/javascript"</span><span style="color: rgb(51, 204, 0);">src</span>=<span style="color: rgb(51, 51, 255);">"rspa/rspa.js"</span><span style="color: rgb(204, 51, 204);">></script></span></small> </big><br>
<br>
2. Provide ID and name for controls like:<br>
<br>
<span style="color: rgb(204, 51, 204);">
<small> <input</small></span><small> <span style="color: rgb(51, 204, 0);">name</span>=<span style="color: rgb(51, 51, 255);">"<big style="font-weight: bold;">text1</big>"</span>
<span style="color: rgb(51, 204, 0);">id</span>=<span style="color: rgb(51, 51, 255);">"<big style="font-weight: bold;">text1</big>"</span>
<span style="color: rgb(51, 204, 0);">value</span>=<span style="color: rgb(51, 51, 255);">"20"</span><span style="color: rgb(204, 51, 204);">><br>
</span><span style="color: rgb(204, 51, 204);">
<input</span> <span style="color: rgb(51, 204, 0);">name</span>=<span style="color: rgb(51, 51, 255);">"<big><span style="font-weight: bold;">text2</span></big>"</span>
<span style="color: rgb(51, 204, 0);">id</span>=<span style="color: rgb(51, 51, 255);">"<big style="font-weight: bold;">text2</big>"</span>
<span style="color: rgb(51, 204, 0);">value</span>=<span style="color: rgb(51, 51, 255);">"30"</span><span style="color: rgb(204, 51, 204);">><br>
</span><span style="color: rgb(204, 51, 204);"></span><span style="color: rgb(204, 51, 204);"></span>
Result: <span style="color: rgb(204, 51, 204);"><input</span> <span style="color: rgb(51, 204, 0);">name</span>=<span style="color: rgb(51, 51, 255);">"text3"</span> <span style="color: rgb(51, 204, 0);">id</span>=<span style="color: rgb(51, 51, 255);">"<big style="font-weight: bold;">text3</big>"</span>
<span style="color: rgb(51, 204, 0);"></span><span style="color: rgb(204, 51, 204);">></span><br>
</small><br>
3. Call server functions from javascript events<br>
<br>
<span style="color: rgb(204, 51, 204);">
<small> <input</small></span><small> <span style="color: rgb(51, 204, 0);">type</span>=<span style="color: rgb(51, 51, 255);">"button"</span> <span style="color: rgb(51, 204, 0);">id</span>=<span style="color: rgb(51, 51, 255);">"button1"</span> <span style="color: rgb(51, 204, 0);">value</span>=<span style="color: rgb(51, 51, 255);">"Calculate"</span><span style="color: rgb(204, 51, 204);"> </span></small><span style="color: rgb(51, 204, 0);">onclick</span>=<span style="color: rgb(51, 51, 255);">" new RSPA.Execute(<span style="font-weight: bold;">'MyClass.multiply()'</span>) "</span><small><span style="color: rgb(204, 51, 204);"></span><span style="color: rgb(204, 51, 204);"> ></span></small><br>
<br>
<br>
4. Create the PHP class MyClass in MyClass.class.php<br>
<br>
<br>
<span style="color: rgb(204, 102, 204);">
<?php</span><br>
<br>
<span style="color: rgb(153, 51, 153);">
require_once</span>(<span style="color: rgb(51, 51, 255);">"rspa/components/Form.class.php"</span>);<br>
<br>
<span style="color: rgb(153, 51, 153);">
class</span> <span style="font-weight: bold;">MyClass</span><small style="font-weight: bold;"> </small> <span style="color: rgb(153, 51, 153);">extends</span> <span style="font-weight: bold;">Form</span><small style="font-weight: bold;">{</small><br>
<br>
<br>
<span style="color: rgb(153, 51, 153);">public</span>
<span style="color: rgb(153, 51, 153);">function</span> <span style="font-weight: bold;">multiply()</span><small style="font-weight: bold;"> </small>{<br>
<br>
<span style="color: rgb(51, 153, 153);">$val</span> = <span style="color: rgb(51, 153, 153); font-weight: bold;">$this</span><span style="font-weight: bold;">->controls[</span><span style="color: rgb(51, 51, 255); font-weight: bold;">"text1"</span><span style="font-weight: bold;">]->getValue() * </span><span style="color: rgb(51, 153, 153); font-weight: bold;">$this</span><span style="font-weight: bold;">->controls[</span><span style="color: rgb(51, 51, 255); font-weight: bold;">"text2"</span><span style="font-weight: bold;">]->getValue();</span><br>
<br>
<span style="color: rgb(51, 153, 153); font-weight: bold;">$this</span><span style="font-weight: bold;">->controls["text3"]->setValue(</span><span style="color: rgb(51, 153, 153); font-weight: bold;">$val</span><span style="font-weight: bold;">);</span><br>
<br>
}<br>
<br>
<br>
}<br>
<br>
<span style="color: rgb(204, 102, 204);">
?><br>
<br>
</span>
5. Change the configuration value in rspaconf.inc.php<br>
<br>
$RSPA['class_folder'] has to set to the folder containg your class files.<br>
<br>
<br>
<br>
Syntax of calling Execute:<br>
<br>
new RSPA.Execute('Class.function', {option :value,...});<br>
<br>
Applicable oprtions :<br>
<small> <br>
</small></big><small><span style="font-weight: bold;">debug: </span> //Whether to show debug window(true/false). Default is false<br>
<span style="font-weight: bold;">loadStatus: </span> //Status message to be displayed while waiting for execute. Default 'Loading...'<br>
<span style="font-weight: bold;">statusPane:</span> //Where to show status message . Default is '__RSPA__loadStatus',<br>
</small><big><small><small> <span style="font-weight: bold;"> widget: </span>
