How to hook into the "close infobubble" event in HERE maps Javascript API -

-

i can create infobubbles using here maps javascript api - eg documentation:

    function addinfobubble(map) {       map.set('center', new nokia.maps.geo.coordinate(53.430, -2.961));       map.setzoomlevel(7);        var infobubbles = new nokia.maps.map.component.infobubbles(),         touch = nokia.maps.dom.page.browser.touch,         click = touch ? 'tap' : 'click',         container = new nokia.maps.map.container();        container.addlistener(click, function (evt) {         infobubbles.openbubble(evt.target.html, evt.target.coordinate);       }, false);       map.components.add(infobubbles);       map.objects.add(container);        addmarkertocontainer(container, [53.439, -2.221],         '<div><a href=\'http://www.mcfc.co.uk\' >manchester city</a>' +         '</div><div >city of manchester stadium<br>capacity: 48,000</div>');        addmarkertocontainer(container, [53.430, -2.961],         '<div ><a href=\'http://www.liverpoolfc.tv\' >liverpool</a>' +         '</div><div >anfield<br>capacity: 45,362</div>');     }     function addmarkertocontainer(container, coordinate, html) {       var marker = new nokia.maps.map.standardmarker(         coordinate,         {html: html}       );       container.objects.add(marker);     }

i hook close event of infobubble. realise use jquery find span contains close button (examining markup, believe has class nm_bubble_control_close) , when clicked. thought there built-in event use.

does know if there built-in event fires when infobubble closed? can't find in documentation.

afaik there no built-in event, there's no related property may observed.

possible workaround: override built-in close-method custom function:

  container.addlistener(click, function (evt) {     var b = infobubbles.openbubble(evt.target.html, evt.target.coordinate),         c = b.close;     b.close = function(){       //do want       alert('bubble closed');       //execute original close-method       c.apply(b)     }   }, false);
