Mathjax being loaded even there are no math equations

[Ramakrishna Salagrama]

Hi, 

Mathjax is being loaded even there are no math equations. 

The following page is being tested : www.campusgate.co.in/p/placement-papers.html

Is there anyway we can stop loading this code as it is delaying loading. 

Regards,

Hi Ramakrishna,

That's the way http works. If you load a library it gets loaded whether or not you are using it. What you could do to circumvent this is Look through the DOM to see if you have any math then load it. If you use mathML then you can try to dynamically load mathML if document.querySelectorAll('math').length > 0 . But I've never done this and don't know if there are caveats to loading mathjax dynamically. It's really not so large if you cover all other performance measures so I let it load on all my pages. Another option could be to let it load async with the async attribute on the <script> tag.
