问题
I'm looking for a way to create dynamic input fields in Meteor.js. I've chosen not to use Aldeed's Autoform for greater control over the code. From front end point of view I have no issues to add dynamic fields with +/- button to add and remove fields. What I'm struggling with is the insert statement on the back end. How can one add dynamic insert in Meteor.js? Cheers!

Essentially you need a reactive array of element that's rendered to the DOM via {{#each}} ... {{/each}}. When the array changes the DOM would re-render.
There's no need to create your own reactive array, there's one here with an example that does exactmy what you're asking for:

However I'd recommend going one step further and using the ViewModel package for this (by the same author). Here's an example which shows how to use it to insert fields:

Thanks Tim, these are both pretty useful. I'm using Collection 2 so decided to use objects ('object.$'). This is easy solution for me. cheers.
