I've got some code in JavaScript and I'm looking to trigger a ViewModel
method using a keyboard shortcut. What is the correct syntax? Here's my code:
document.addEventListener('keydown', function(event) {
if (event.keyCode==27){
ViewModel.escapePressed();
}
}, true);
function ViewModel() {
this.escapePressed=function(){
// Code
};
}

If you are going to use that style of class, then you must first make an instance of it.
var a_view_model = new ViewModel();
a_view_model.escapePressed();
… but if you just want to have a static method, then you probably shouldn't be using a constructor function in the first place
var view_model = {
escapePressed: function () { };
}
and:
view_mode.escapePressed();
