javascript - Dynamically changing an icon in Twitter Bootstrap 3 -


take here (it uses jquery, knockoutjs, twitter bootstrap 3):

http://jsfiddle.net/ncufy/3/

<i class="glyphicon" data-bind="click: function() { ispaused(!ispaused()) }, css: {'glyphicon-play': ispaused(), '.glyphicon-pause': !ispaused()}"></i>  var viewmodel = {     ispaused: ko.observable(true), };  ko.applybindings(viewmodel);

when click on play icon, icon disappears. instead, icon should turn pause icon. wrong? use latest chrome.

you have . in front of glyphicon-pause. remove it

demo: http://jsfiddle.net/tymejv/ncufy/4/

css: {'glyphicon-play': ispaused(), '.glyphicon-pause': !ispaused()}                                      ^ dont belong there!!
