The example shows how to use KoolAjax to call a PHP function from client-side.
When Calculate button is clicked, values of two first input boxes will be sent to server to be calculated.
Later the result is sent back to client and shown in last input box. All are done silently without refreshing page.
<?php
require $KoolControlsFolder."/KoolAjax/koolajax.php";
$koolajax->scriptFolder = $KoolControlsFolder."/KoolAjax";
function calculate($x,$y)
{
return $x+$y;
}
//Enable calculate function to be called at client-side
$koolajax->enableFunction("calculate");
?>
<div style="height:50px;padding-left:10px;">
<?php echo $koolajax->Render();?>
<style type="text/css">
#loading
{
position:relative;
left:-22px;
top:3px;
visibility:hidden;
}
</style>
<input id="txtX" type="textbox" value="2" /> +
<input id="txtY" type="textbox" value="3" />
<input id="btnCal" type="button" value="Calculate" onclick="btnCal_Click()" />
<input id="txtZ" type="textbox" />
<img id="loading" src="Images/loading.gif" alt="Loading..." />
<script type="text/javascript">
function btnCal_Click()
{
x = document.getElementById("txtX").value;
y = document.getElementById("txtY").value;
koolajax.callback(calculate(x,y),onDone);
document.getElementById("loading").style.visibility ="visible";
}
function onDone(s)
{
document.getElementById("txtZ").value = s;
document.getElementById("loading").style.visibility ="hidden";
}
</script>
</div>
