如何选择文本区域中的部分文本并将其复制到剪贴板？

Question

Could anyone tell how to select portion of text in textarea and copy it to clipboard by using javascript? I know how to select all text in textarea and copy it? My question is that when we use mouse to select part of text in textarea, how to copy it to clipboard.

Answer 1

How about this

(on)select save the start and end position of the selection to the input element itself.

event.target.lastSelection = { start:startpos, end:endpos};

and use the (on)blur event to do something like

event.target.setSelectionRange( event.target.lastSelection.start, event.target.lastSelection.end )?
