Hi,
I want to do the button for subscript and superscript. For example now, when we r typing the question in this textarea, if we want to highlight the main text we r selecting the statement and we click the B for bold. Then our statement becomes like <b>.....</b> Like this i want to do for subscript and superscript. If i give X2 I want to do like X<sub>2</sub>. Please tell me how to do this.

Search for a WYSIWYG editor. There are a variety of JavaScript based editors that will do that for you. Building one yourself is very complicated.

Code:

<button type="button" onclick="addtext();getfocus();">Subscript</button>

function addtext() {
var newtext = document.getElementById("ques1").value;
newtext += prompt("enter the value",'<sub></sub>');
document.getElementById("ques1").value = newtext;
document.getElementById('ques1').focus();
}

The above is my code. I did it for one textarea. But if i'm having another textarea and i want to include the subscript in that textarea only, How can i do this.Please tell me.
