I wrote a plugin to allow keyboard shortcuts while editing a tiddler a
while back [1]; it uses jQuery to get the textarea as a DOM element,
which has the properties selectionStart and selectionEnd. These give
the position of selected text in characters relative to the textare
text (value property) and are the same if nothing is selected.
So, for example, suppose the textarea contains "Now is | time" and you
want to insert "the" at the cursor position and reposition the cursor
after it:
var domEl = jQuery('textarea').get(0);
var cStart = domEl.selectionStart;
var cEnd = domEl.selectionEnd;
var newText = domEl.value.substring(0,cStart) + "the";
newText += domEl.value.substring(cEnd);
domEl.value = newText;
cEnd += 3;
domEl.setSelectionRange(cEnd,cEnd);
Hope that helps,
Jon
