I want to call a child component's function from its parent. I have a way to do it, but I want to know if I'm missing a better way.
From Ashley Grant's blog post about accessing a custom element's viewModel from a custom attribute, I see that Aurelia adds
au to the element and you can access the viewModel through that. So, if I add a nested component with a ref, like this:
<template> <nested-element ref="childElement"></nested-element> </template>
I can call a function on it like this:
This feels roundabout. I was hoping I would be able to access a nested element's viewModel through the parameters to a hook that the parent implements, such as
created(owningView, myView) but I can't find a path to it.
Have I missed a better way?
Edit: I forgot to add that I need a return value from the function I'm calling, so having access to the viewmodel itself is preferable
