Question

I started reimplementing some js code with knockout.js.
I have a singleton with some functions in it:

Dps = {
    someFunction: function() {
        this.anotherFunction();
    },
    anotherFunction: function() {
        console.log('tehee');
    }
}

Now there are also some bindings which calls functions of this singleton:

<input type="text" data-bind="event: { change: Dps.someFunction }" />

The annoying thing is, that the context in the called function is the event, so I can’t call this.anotherFunction()

Is there a nice way to get rid of this?

PS: I’m aware that I could do something like Dps.someFunction() instead, but this is not nice in my opinion.

Answer 1

data-bind="event: { change: Dps.someFunction.bind(Dps) }"
