Check if attribute exists in directive
I want to check if an attribute exists in a directive and I don't know how to do that, can anyone help? this is probably simple but I am new to angular
(function() {
'use strict';
angular.module('app').directive('home', home);
var strVar="";
strVar += "<home show-text=vm.text></home>"
function home() {
return {
restrict: 'E',
transclude: true,
template: strVar,
scope: {
showText: "="
},
controller: HomeController,
controllerAs: 'vm',
bindToController: true
};
};
HomeController.$inject = ['$scope','$rootScope', '$timeout','$sce'];
function HomeController($scope,$rootScope,$timeout,$sce) {
if(vm.showText == “undefined”)
{
//Run some code
}
})();

the '?' is making an attribute optional,
then in the controller check if the attribute exists with angular.isUndefined(vm.showText) or with typeof vm.showText === 'undefined'
for more info check out angular 1.7.x - Error: $compile:nonassign
