Answer 1

window.getSelection().toString() worked for me with Chrome but not Firefox.

For obtaining the selected content in a <textarea> with Firefox:

function getSel() // javascript
{
    // obtain the object reference for the <textarea>
    var txtarea = document.getElementById("mytextarea");
    // obtain the index of the first selected character
    var start = txtarea.selectionStart;
    // obtain the index of the last selected character
    var finish = txtarea.selectionEnd;
    // obtain the selected text
    var sel = txtarea.value.substring(start, finish);
    // do something with the selected content
}

You could also use activeElement instead of getElementById.

• textarea
