Developing an Ajax and JavaScript based application can be easily done with jQuery. As one of the most powerful frameworks, it has become the choice of many developers on how to create an application. It can work with ASP.Net or it can be used as a standalone framework to create an application. Developer support is even impressive as there are small libraries created for specific functions everyday. Once the framework is implemented in an Ajax based application, the functions from jQuery can be called and implemented in the client side.

But there are times that when a jQuery is implemented, its effects in the application should be limited. The functions in an Ajax or JavaScript based application will be based on jQuery once the programming language is used. Some developers can fully rely on jQuery for their needed functions but there are situations that a specific part of the application should not be used with jQuery.

There are actually three methods a developer can consider to enable restriction of jQuery in the application:

• Separation through hash tags – Developers can create a function, table or tools that will not be used with jQuery as long as they are properly tagged in the application. Using hashtags (#), developers can customize the specific function so that it can be implemented without the influence of jQuery. Developers may have to manually code the function because it is separated from jQuery.

• Creating context – This is a very smart option especially when you need to implement a relatively bigger function that should not be affected by jQuery. Instead of using hash tags to separate the content, developers can create a specific selector so that it can influence the functions within it’s table. This selector can be considered as an "outside" function because it is separated from the rest through context. The challenge to this format is that it could be treated as a 3rd party source which is restricted in JavaScript and Ajax based application.

• Adding class – This can also be likened to the previous function except that it uses variable class to separate the specific function. It can also be likened to the use of hashtags because it will require developers to create a unique ID. This ID is not necessarily implemented in the rest of the application but it will differentiate itself from other functions implemented with the help of jQuery.

These are the three options in implementing restrictions for jQuery in an Ajax based application. Why the three options? Because limiting a framework is not necessarily a guaranteed practice in an Ajax based application. Developers have to try one of these options in case the other option will not work in their specific application.

Aside from jQuery, developers can also consider this method if they want to use other frameworks in the online application. These simple tricks to limit the implementation of jQuery (and other frameworks) should help you get started in building a highly customized JavaScript and Ajax based application.
