However, you may enter a script in module header (in module settings).

Hello: 

First, please know that I moved this forum thread to another forum category to make it easier for everyone to find in the future.  

Now, the HTML module is not meant to be used for advance HTML scenarios like this one.  It's not completely a limitation of the module itself, but really a commentary on the WYSIWYG HTML editors and how they handle things.  In your case, it's also a borderline security protection to some degree.  

If you wish to inject HTML into the page that isn't content-related, you're really left with 5 options.  

1. If you must use the HTML module, you still can, but know it comes with some usability issues. You'll need to use the Basic Textbox Editor feature (dropdown on the bottom), and then selecting HTML.  This will give you a textarea where you can freely enter any HTML you want, but it's not easy to train non-technical people on how to use it and when, and it will end up being completely wiped out if you accidentally edit this content using another method.  
2. I've long used a content injection module that helps manage HTML elements like this, while giving a usable UI for individuals to use. 
3. Use structured content to inject the content. This can be done multiple ways, including using OpenContent and 2sxc.  
4. Add the script to your theme and have it load either with each page load, or add some conditional logic to only load it sometimes.  
5. Add the script using another module that needs it (but only if your scenario involves a custom module already).  

Thanks for your prompt response,

My issue is I am not able to add javascript code in either any module Header or Page Header but earlier it was working fine but suddenly it stopped working, I could not recall what kind of changes I did so that this type of issue is coming. This is a global issue.
Please guide.

Well, I just gave you five options to add scripts to your website.  If a script stops working without any edits, then there needs to be a bunch of troubleshooting.  Unfortunately, you need to just follow the path of the script to determine why it didn't load.  It might be a caching issue, browser issue, file availability, file path, antivirus, CDN, and a number of other potential causes.  Without a clear condition that can be reproduced, we'll be very limited in how we can help and most things would literally be a guess.  Sorry.  :(
