作用域变量在函数内部未定义-AngularJS

Question

I need to call a function with scope variables. Its getting undefined inside function there.

setstates($scope.events.myevent,bannerslidesmyevent,$scope.eventPlus,$scope.myeventtime,myeventcurrenttime);

Definition:

function setstates(event,banner,eventplus,eventtime,currenteventtime)
{
  if(event ===null || event ==='null' || event ===undefined)
    {
        banner.goto(2);
        eventplus = -1;
    }
    else if(event[0] === '+')
    {
        banner.goto(2);
        eventplus = event.split('+')[1];
    }
    else 
    {
        currenteventtime.setHours(event.split(':')[0]);
        currenteventtime.setMinutes(event.split(':')[1]);
        eventtime = currenteventtime;
    }
}

Issue is with $scope.myeventtime ,which is eventtime inside function, getting undefined.

HTML:

<timepicker class="timepicker" ng-model="myeventtime" hour-step="hstep" minute-step="mstep" show-meridian="ismeridian"></timepicker>

The time is not being set.

Answer 1

You are changing the pointing value of a local variable eventtime not the original scope variable. Since this is a date object you can do that instead:

eventtime.setHours(event.split(':')[0]);
eventtime.setMinutes(event.split(':')[1]);

this will act upon the original scope param as setHours and setMinutes are methods of the original object.

Edit : Just realized you are attempting to set both currenteventtime and eventtime to the same value. you would need to run setHours and setMinutes on both then
