javascript - Online and offline event are firing twice -

can please help?

i trying check when internet conectivity lost in ionic project, working fine event fires twice in row reason. below code in app.js in $ionicplatform.ready:

if (window.connection) {     $rootscope.$on('$cordovanetwork:online', function (event, networkstate) {        console.log('we online');    });     $rootscope.$on('$cordovanetwork:offline', function (event, networkstate) {        console.log('we offline');    }); } 

like said works fires twice in row, when want display popup when internet connection lost displayed twice.

i checked ionic forum , found guy similar problem no 1 gave him exact answer: http://forum.ionicframework.com

this workaround using state dummy var

var isonline = true;    if (window.connection) {       $rootscope.$on('$cordovanetwork:online', function (event, networkstate) {       if(isonline) return;              isonline = true;              console.log('we online');     });       $rootscope.$on('$cordovanetwork:offline', function (event, networkstate) {         if(!isonline) return;                isonline = false;                console.log('we offline');     });  }
