You assign an empty string e.g. here:


document.getElementById("result").value= '';

Why you wonder that text is empty after that?

no no i added html tags inside but the site didnt display it sorry , so if i click bold , it adds bold tags but if i click italic it should add italic beside bold tag, but its clearing bold tag and adding italic tags

I don't get it. But anyway think about
document.getElementById("result").value+=
instead of
document.getElementById("result").value=

This one

document.getElementById("result").value= ...

will replace the whole content. So what I understand you like to add and therefore you should take into account something like

document.getElementById("result").value+= ...
