browser - How to get a word under cursor using JavaScript?

Question

If I for example have

<p> some long text </p>

on my HTML page, how can I know that cursor of mouse is for example above the word 'text'?

Answer 1

Further to the two other answers, you may be able to split your paragraphs up into spans using jQuery (or javascript generally).

That way, you wouldn't need to think about outputting your text with spans around the words. Let your javascript do it for you.

e.g.

<p>Each word will be wrapped in a span.</p>
<p>A second paragraph here.</p>
Word: <span id="word"></span>

<script type="text/javascript">
    $(function() {
        // wrap words in spans
        $('p').each(function() {
            var $this = $(this);
            $this.html($this.text().replace(/(w+)/g, "<span>$1</span>"));
        });

        // bind to each span
        $('p span').hover(
            function() { $('#word').text($(this).css('background-color','#ffff66').text()); },
            function() { $('#word').text(''); $(this).css('background-color',''); }
        );
    });
</script>

Note that the above code, while it works, will strip out any html inside your paragraph tags.
