骨干网 - 传递索引视图遍历集合时？

Question

I'm trying to render a View which needs to know the index position of the Model passed in inside its Collection:

Parent View

collection.each(function($_v, $_k) {
    (new view({model: $_v, index: $_k})).render();
});

Child View

className: function() {
    0 === this.index % 2 ? 'colored' : '';
}

However it appears that this.index can't be set this way and become undefuined . What is the proper to make this work?

Answer 1

I think it should be:

className: function() {
    0 === this.options.index % 2 ? 'colored' : '';
}
