Calling a function using external JavaScript file. We can also call JavaScript functions using an external JavaScript file attached to our HTML document. To do this, first we have to create a JavaScript file and define our function in it and save itwith (.Js) extension. Once the JavaScript file is created, we need to create a simple HTML document. Second - you need to put it into request. There is two ways - use filter or controller/action. First option is useful when you want to use same variable from different GSP.

With the call () method, you can write a method that can be used on different objects. All Functions are Methods In JavaScript all functions are object methods. If a function is not a method of a JavaScript object, it is a function of the global object (see previous chapter). When you call your action with ajax the response of the action is rendered into an object. You can then show the result of the action (in your case a different action - the list action) by manipulating the DOM with Javascript. You can, ofcourse, call the action with javascript without ajax: 10.3 Asynchronous GORM. Since Grails 2.3, GORM features an asynchronous programming model that works across all supported datastores (Hibernate, MongoDB etc.).

Creates a form tag that uses a remote uri to execute an Ajax call, serializing the form elements and falling back to a normal form submit if JavaScript is not supported,This tag creates a form that fires an AJAX request when it is submitted. The exact Javascript used to fire off the AJAX request depends on which Javascript library is used. The JavaScript manages the notifications and calling the custom action.

When the action completes, it will call the success callback and display the information on the form as a notification.

A class is only considered to be a command object when it is used as a parameter of an action. We will need to specify a server side script (in PHP terminology) or a controller action (in Grails Terminology) that will fetch data from the mysql database and serve it to the jquery call.
