Cannot select text with Firfox!

[Volatire666]

Here is the scenario: I have a textarea with text in it and I want to select/highlight predefined text within the textarea with a function. This code using ranges works with IE -

selectText = function(node, text)
{
var range = document.body.createTextRange();
range.moveToElementText(node);
range.findText(text);
range.select();
}

Firefox handles ranges completely differently and is not very well documented. I have got as far as creating a range which includes all the text in the textarea -

var range = document.createRange();
range.setStart(node, 0);
range.setEnd(node, 1);

I'm not sure where to go from here. Any further ideas on how to create a selection of text within a textarea?

I've finally figured it out for anyone else with similar problems:

selectText = function(node, text)
{
if (window.getSelection)
{
node.selectionStart = node.value.lastIndexOf(text);
node.selectionEnd = node.value.lastIndexOf(text) + text.length;
node.focus();
}
else if (document.selection && document.body.createTextRange)
{
var range = document.body.createTextRange();
range.moveToElementText(node);
range.findText(text);
range.select();
}
}

This should work with the latest IE and Firefox. I've not tested it on anything else.
