Loading external javascript files in web page

External java script files will be included into web page by using <script> tag. 

Here is the example of including external java script file in web page. 

<script src="Cmmon.js" type="text/javascript"></script> 

Script tag should be closed properly. The following example is wrong way of including external java script files. 

<script src="Cmmon.js" type="text/javascript" />

With the above statement only one javascript file will be loaded into page, when you try to load multiple java script files.

this._form is null javascript error

Here is one scenario which I had faced in my application for this issue. 

I had included some of the external java script files in my application with below syntax. 

<script src="Common.js" type="text/javascript" /> Wrong 

It is wrong the script tag should be closed with “</script>” instead of "/>". Then only all the scripts will be loaded into the page properly. 

<script src="Common.js" type="text/javascript"></script> Correct
