Can we pass whole of the object as a parameter in apex class from the java script controller?

Hello Anurag,

Yes, you can pass the whole Object as a parameter in apex class from the javascript controller. Here are the simple steps to do this:-

1. Call the apex class method in javascript by using action =component.set("c.nameOfMethod");
2.  Then pass the parameter using action.setParams("variableNameInMethod": variableNameInJavascriptController);
3. Execute the action in javascript.

Hope this will help you.

Thanks.
