Lightning Component Attribute

Question

I have a lightning component with a child component. I'm passing an array of object to the child. It seemed that there was an attribute that I could set to invoke a function once the child attribute was loaded. I thought is was named something on the line of "?afterloading?" or sort. I can't seem to find documentation anymore. I'm using a change handler to handle the situation but this is for a piece of mind.

I thought I could do something as follow:

<aura:component>
<aura:attribute name="foo" type="object[]" afterloading="{!c.dosomething}">
</aura:component>

Answer 1

The only attributes for attributes are listed here. They are:

• access
• name
• type
• default
• required
• description

And no, you're not missing anything; you'd use an aura:valueChange listener, as you're doing, to listen for changes. You were most likely thinking about afterScriptsLoaded on the ltng:require component, which would be used to call some initialization script after loading external libraries.
