如何删除ractivejs对象

Question

I know in vanilla JS you can just use the delete command to remove an object but I can't find anything in the docs for object manipulation.

For example how would I delete this object in ractivejs?

template.set('object', {hello: 'world', bye: 'world'});

I want to later on delete the bye object from that 'object'.

From the template's perspective, it usually doesn't matter if you just set the value to undefined :

template.set( 'object.bye' );

Unless you're using it in a hash, then you can delete the key and call update:

delete template.get( 'object').bye;
template.update( 'object.bye' );

It's currently a requested feature ( https://github.com/ractivejs/ractive/issues/1649 ) to add an unset method:

template.unset( 'object.bye' );

If you look in the comments on that issue, there's a Ractive.prototype.unset polyfill you can use.
