Pre-Built Scripts

Pre-built scripts in any programming language are considered as “shortcuts” to quickly develop a website or online application.

Instead of manually coding, you can search the code online and apply them on your website. But pre-built scripts are not common in other programming languages.

JavaScript is one of the most popular programming language but also very challenging. One can easily achieve highly interactive online applications with the help of JavaScript but they are very complex especially when JavaScript is used to build Ajax based applications. With the help of pre-built scripts of JavaScript, developers aim to lessen the burden by using these scripts.

Pre-built scripts do not automatically transform your website into something remarkable. It might even be possible for the website to crash because the pre-built script might not work or just attack the online application because of the virus it comes with.

But the biggest challenge for pre-built scripts is not on performance and viruses since developers can easily identify them because they come in raw coding. The biggest problem developers have to deal with when using pre-built scripts is the browser incompatibility.

Unfortunately, the functions on JavaScript can’t be easily read by some browsers. Aside from IE, developers have to check with other browsers to ensure their compatibility.

The Manual Way

The easiest way to test your scripts is to manually check them in your browser. After integrating the pre-built scripts in your website, you can launch it different browsers an see them if they will work without any problem.

This technique is highly recommended for those who are adding very small pre-built scripts. Instead of using applications to check browser incompatibility, the simpler strategy is just to launch them in different browsers. Of course, this is useful when you already have a completed online application.

Software and Other Codes

On the other hand, there is still a way that you can check if the pre-built script will work on different browsers. There are a good number of applications that you can use to check the browser compatibility. However, these applications will usually require a small fee and the free ones are just too dangerous to be used.

Fortunately, there are techniques on how you can check the specific script without using a 3rd party application. The following are the scripts that can help you figure out browser compatibility:

• navigator.appBrowserName – This form of command could be launched as part of the pre-built script. Add the browser name so that you’ll have a good idea on how the script will work on the browser. This could also be used as a clue. If you see this code already added in the script, there is a big chance that the pre-built script will not work on other browsers.

• document.all – This form of command is highly recommended in checking pre-built scripts in IE version 4+. When the return is positive, it can suggest that the script in other major browsers will work as well.

Carefully choose your pre-built scripts. By screening them for security and compatibility, you can easily build a highly interactive Ajax or JavaScript based online application.
