I want to apply some changes to the selected text of a text area only.
I want to select a certain portion of a text written in the text area and want to make some changes on it by javascript.
Thanks

It shows you selection of the text and you can use javascript to process it.
document.selection.createRange().text = "NEW TEXT";
