Conflicting Pre-Built Scripts

Pre-built scripts for JavaScript is one of the best ways of developing an application with little programming knowledge. The current popularity of Ajax and JavaScript as programming languages is due to the increasing support for the programming language. Free scripts are available online and they are available for everyone interested in developing an application.

Through pre-built scripts, those who are creative enough in thinking of concepts for a website can easily develop an online application. They don't even have to spend hundreds of dollars in hiring developers since they can practically assemble scripts to create an online application.

But developing an Ajax based application is not just copying and pasting codes in the application and expect them to work. One of the biggest challenges for developers who wanted to use pre-built scripts is clashing scripts. This often happens since additional functions are needed in a single webpage. When using two or more scripts in a webpage, it's possible that the scripts will be conflicting.

Occupied Function

The common problem in conflicting scripts is when the 2nd script you opt can't be placed in the same location since it has already been occupied by the first script. This can happen especially when the scripts are trying to use external sources in the application. In this scenario, the first script will still be working without any problems but the second script will never work.

Dealing with this problem will require you to specify each function within the tag. No need to create another script as long as you inform the application that you are placing two distinct scripts. This will inform the browser that it needs to read the script twice since an additional script has just been added. This usually happens in your headers and onload scripts.

Negating Scripts

One of the biggest challenges a non-developer could have when adding a second script in a single webpage is when both functions ceases to work after the 2nd function has been added. Instead of simply overriding the existing script, the functions in the application will never work.

Even though this problem can lead to serious repercussions in the application, the solution is relatively simple. When two functions do not work after the 2nd script has been added, this is usually a problem on naming the functions. Change the name of the functions as well as the variables in order to create a completely new function in the same webpage.

"Fighting" Scripts

"Fighting" scripts is basically two set of scripts that have conflicting functions in a single webpage. For example, the 1st script can tell the application to move the text up while another function tells the application to move the text down. When this happens, your script will simply fail to execute.

If you think your script is conflicting, the only logical solution to the problem is to change one of the scripts. Two conflicting scripts should never be placed in a single webpage. Either you have to remove one of the functions or change one of the functions to avoid script conflict.
