what is that extension?
you should have told this at the first place ?
url for that library?

Member 11663301 20-May-16 10:57am

YES, we can specified url by extension , whatever we whant,
i used whtever u guided , but error shows (Error: Cannot set property 'innerHTML' of undefined) ,
but i used one tag script , example: var X= document.getElementsByTagName("script")[2];
X.innerHTML ="" ; it is working properly

Karthik_Mahalingam 20-May-16 10:59am

that means you have to traverse the exact location of the script tag..
post your complete html, i will give you the exact code..
