This blog will explore the concept of passing object to angularJS directives / templates using by reference.
When an object is passed by reference both the parent (controller or parent directive) and the child directive/template have access to the object. The relationship is bidirectional.
This tutorial details creating directive/templates in general (without an isolated scope).
This tutorial demonstrates passing values by value to angular directives/templates (@).
The purpose of this blog is to demonstrate how to use templates in AngularJS. A fully worked example is provided via jsFiddle. The example is simple and easy to follow. A detailed but succinct explanation of the code is provided.
The template is “complex html” that we’ll want to reuse. The directive will allow this complex html to be delivered anywhere without code duplication. This obviously has advantages in terms of code reuse and maintainability.
AngularJs uses Dependency Injection (DI) to supply objects/variables during configuration.
Variables that begin with the $ character tend to be injected, therefore if a minimizor and/or obfuscater changes the variable name, the DI will not be performed.
A much better approach to this problem is simply to use JSON. A number of comments below are in regard to nested lists. The solution detailed here does not readily facilitate nested lists. The solution outlined in this blog does: http://outbottle.com/spring-4-web-mvc-json-handling/. JSON is the recommended way of achieving “Adding Objects to a List element on the fly”
Alternatively, this blog also demonstrates the solution:
The project downloadable below is an answer to a question repeated in this blog (Spring 3 MVC – Adding Objects to a List element on the fly at form submit – (Generic method))
“How can I submit nested lists of objects?”
The answer is AJAX and JSON.
A very good approach to this is with AngularJS and Spring as demonstrated here.
ok, hard to describe this one and hard to find stuff on google so here’s an image explaining.
This tutorial demonstrates how to handle exceptions in Spring 3 Web MCV.
