Typescript enum switch not working

Question

i have the following enum

enum EditMode {     View = 0,     Edit = 1,     Delete = 2 } 

Let's assume i have a variable of the enum type

var editMode = EditMode.Edit; 

Why does the following code not work (goes straight to default)?

switch (editMode) {     case EditMode.Delete:         ...         break;     case EditMode.Edit:         ...         break;     default:         ...         break;     }

I also had this problem. Easy way to get around it: add a + sign before your variable in the switch, i.e.

switch (+editMode) {     case EditMode.Delete:         ...         break;     case EditMode.Edit:         ...         break;     default:         ...         break;     } 

Answer 2

i have found why i does happen. somewhere in the code there is a activation function (i am using durandal) which passes this enum as a string (the function has the parameter marked as a enum but still it is a string). this is why my switch statement fails. i simply converted the value to a number and now everything works as expected. thanks anyways
