Call one function from another

Question

I have a custom function according to documentation. What documentation doesn't cover (or I'm blind) is how to call one function from another. Here is what I tried:

var myRactive = new Ractive({
    el: '#element',
    template: '#template',
    data: {
        function1: function() {
            return 100;
        },
        function2: function() {
            return function1() / 2;
        }
    }
});

It doesn't work. I tried to change it to myRactive.function1(), myRactive.data.function1(), etc. but neither of them worked out.

You can use this.get('function1') to get it from your data object, then run it as a function like this.

var myRactive = new Ractive({
el: 'body',
template: '#ele',
data: {
    function1: function() {
        return 100;
    },
    function2: function() {
        return this.get('function1')() / 2;
    }
}
});

In pre 0.7 ractive, you could access the data-object directly (this.data). This got changed, and you should now use this.get() and this.set() instead.
