Can JS detect SELECTED text in a textArea

[STB]

Hi,

Can you pick out just the text that a user has selected in a TextArea using
JS?

It depends on whether the browser offers an API, some like Netscape
7.1/7.2, Mozilla 1.4 or later, Firefox do with
textControl.value.substring(textControl.selectionStart,
textControl.selectionEnd)
and IE/Win also does
document.selection.createRange().text
others like Opera don't offer an API.

Don't imitate this, because it is bad code, but in IE you can do
something like this:

function wrapSelectionBold (element) {
var range = document.selection.createRange();
if (range.parentElement() == element) range.text = '<b>' +
range.text + '<\/b>';
}

<input type="button" value="bold"
onclick="wrapSelectionBold(this.form.inputId)" />

1. The thread you point to does not answer the OP's question.
However, other threads do:

2. Mozilla Firefox and Venkman don't work well together, since Venkman was
designed for debugging with Mozilla Seamonkey; one should use that UA
instead.
