Case Description:
Although no specific args attribute is defined in Childctrl, because the scope of the Childctrl inherits from the Parentctrl scope,
As a result, Childctrl is linked to the parent scope args property and set to input via a prototype. and the input values in the parent input are synchronized to the sub input.
But not on the contrary. The child is modified, the value in the parent cannot be changed, and the child is not synchronized after the parent is modified, because when the child scope input is input,
Because model is explicitly bound to the scope of Childctrl in the HTML code, Angularjs generates a args original type attribute for Childctrl.
Depending on the ANGULARJS scope inheritance prototype mechanism, Childctrl finds the args attribute value in its scope, so it does not look up args values from the parent.
Causes the final child scope to have the args, the parent scope has the args, the child and the parent's value does not maintain the synchronization again.
The above mentioned is the entire content of this article, I hope you can enjoy.
