javascript - Sencha Touch 2: Listen for tap on two different HTML buttons -

in nested list have 2 html buttons. have listener nested list displays detailcard holding 2 buttons, add listener action when 1 of buttons pressed. each button different, have been unable delegate 1 of buttons particular function. there way like:

listeners : { element  : 'element', delegate : 'button.mybutton', tap      : function() {     //...   } } 

but multiple delegates each delegate else?

you add data attributes buttons , react accordingly:

<button data-do="showdetailcard"> <button data-do="anotheraction">  // ...  listeners: {     tap: {         element: 'element',         delegate: 'button',         fn: 'doaction'     } }  // ...  function doaction(event) {     var = event.target.dataset.do;     if (do === 'showdetailcard') {         // show detail card     } else if (do === 'anotheraction') {         // action     } }
