I'm writing a graphic captcha test that uses dragged icons. I'm
trying to store the draggable objects in an array that is a member of
my Captcha class. However, the code fails to work, without error or
warning message, if I try and set the member array elements as I call
'new Draggable'. If I use a local array the code works. Here's the
working code:
var Captcha = Class.create({
_click: function( event ) {
event.stop();
this._icons.each( function( icon ) { icon.destroy(); } ); // free
this._refresh();
}, // end _click
_Complete: function() {
var icons = new Array();
var options = { revert: true, constraint: 'horizontal' };
$( 'captcha_refresh' ).observe( 'click',
this._click.bind( this ) );
$$( '.draggable' ).each( function( el ) {
icons.push( new Draggable( el.id, options ) );
});
this._icons = icons.clone();
}, // end _Complete
_refresh: function() {
var options = { onComplete: this._Complete.bind( this ) };
new Ajax.Updater( 'captcha', this._url, options );
}, // end _refresh
initialize: function() {
this._url = './captcha.php'; // url of the captcha script
this._icons = new Array();
this._refresh();
} // end initialize
}); // end of captcha
