How to use ng-click with multiple expressions? [duplicate]

Answer 1

You can write only expression into ng-click.

The ngClick directive allows you to specify custom behavior when an element is clicked.

But you can write:

{{book.title}}

In this case navigation.book gets book content.

Demo Fiddle

Reference

We have several options here to invoke navigation.book = book

What's happen if we will write:

ng-click="( bookSvc.showBook(book) && (navigation.book = book))"

In this case if (seems like bookSvc is a service) bookSvc.showBook(book) returns nothing or false, the navigation.book = book will never execute.

Demo 2 Fiddle

But if bookSvc.showBook(book) returns true the navigation.book = book will be invoked.
