static Array in typescript

Question

Hi I am new to Typescript and I need to use static array in my code. But when I declared array as follows

private static arrayname:String[];

When I typed this. it didn't show me the array name so I can't able to push any values into this array. Can any one help me in this?

Solution

You should use class name instead of "this":

class A {
    private static arrayname: string[] = ["a", "b", "c"];

    someFunc(): number {
        return A.arrayname.length; // Here I'm calling private statis property
    }
}


var instanceA = new A();
alert(instanceA.someFunc());

This code works for me in the Typescript playground.

Note

You can use private member inside class functions only. It isn't accessible and visible outside the class declared in.

I tried that too my class name is Sample but when I tried Sample. it doesn't shows the array name

now I can push data but I want it to use it outside the class hence I have changed to public but the array is not visible outside

Public members defenitely are visible from outside the class. The problem can be if classes are declared in different namespaces.
