Parent/Child Message Passing using Attributes
<!-- Parent component "parent.cmp" -->
<aura:component>
<aura:attribute name="myAttr" type="String" default="world" />
<c:child myAttrChild="{!v.myAttr}">
</aura:component>
<!-- Child component "child.cmp" -->
<aura:component>
<aura:attribute name="myAttrChild" type="String"/>
<lightning:input name="input1" label="Enter some text" value="{!myAttrChild}" />
</aura:component>
/**
* parentController.js
*/
({
fooMethod : function(component, event, helper) {
var myAttrChild = component.get("v.myAttr");
console.log("myAttrChild: ", myAttrChild);
}
})
If user enters some value in input1 in child component and then fooMethod is called,
myAttr in parent will have the same value as myAttrChild.
