AJAX framework
This built-in JavaScript framework provides simple but powerful AJAX capabilities. Check out the calculator example below.
The HTML markup for this example:
<!-- The form -->
<form data-request="onTest" data-request-update="calcresult: '#result'">
<input type="text" value="15" name="value1">
<select name="operation">
<option>+</option>
<option>-</option>
<option>*</option>
<option>/</option>
</select>
<input type="text" value="5" name="value2">
<button type="submit">Calculate</button>
</form>
<!-- The result -->
<div id="result">{% partial "calcresult" %}</div>
The calcresult
partial:
{% if result %}
The result is {{ result }}.
{% else %}
Click the <em>Calculate</em> button to find the answer.
{% endif %}
The onTest
PHP code:
function onTest()
{
$value1 = input('value1');
$value2 = input('value2');
$operation = input('operation');
switch ($operation) {
case '+' :
$this['result'] = $value1 + $value2;
break;
case '-' :
$this['result'] = $value1 - $value2;
break;
case '*' :
$this['result'] = $value1 * $value2;
break;
default :
$this['result'] = $value1 / $value2;
break;
}
}
