javascript - How to tell if key is held down at click -

this question has answer here:

• check ctrl / shift / alt keys on 'click' event 9 answers

i want able tell if user holding down "shift" key (or key, really) when user clicks something.

i'm able tell if user clicks (by using .click() method on element in directive) , if user presses key, can't figure out how tell if user holding down key @ click time in angular.

any appreciated.

try use ngkeydown directive. calling on view this.

ng-keydown="myfunct($event)" 

myfunct this.

$scope.myfunct = function(keyevent) {     if (keyevent.which === 16) {// 16 == shift. guess;         $scope.shift_is_been_pressed = true;     } } 

so. same ngkeyup directive.

ng-keyup="myfunct($event)"  $scope.myfunct = function(keyevent) {     if (keyevent.which === 16) {// 16 == shift. guess;         $scope.shift_is_been_pressed = false;     } } 

now, able use shift_is_been_pressed determine if shift been pressed or not.
