Function bind

  • bind<Scope, MethodName, Partials>(scope, name, ...partials): ((...args) => any)

  • Creates a new function, which has this bound to scope. Only difference to Function.bind is, that it can bind a string value so the real executed function may change in the scope. Hint: It is semantically equal to the behavior of dojo/_base/lang#hitch.

    Type Parameters

    • Scope
    • MethodName extends string
    • Partials extends any[]

    Parameters

    • scope: Scope

      the this object

    • name: MethodName

      the function or the name of a function.

    • Rest ...partials: Partials

      a custom argument list.

    Returns ((...args) => any)

    a callable function

      • (...args): any

      • Parameters

        • Rest ...args: any[]

        Returns any

    Deprecated

    use Function.bind instead

    Example

    let x = {
         count : 1,
         inc(i){
             return this.count+=i;
         }
    };
    // use "name" binding
    let inc = bind(x, "inc", 5);

    assert.equal(inc(), 5);
    assert.equal(inc(), 10);
