How to add a Tooltip to a "td" with jquery?

Question

I need to add a tooltip/alt to a "td" element inside of my tables with jquery.

Can someone help me out?

I tried:

var tTip ="Hello world";
$(this).attr("onmouseover", tip(tTip));

where I have verified that I am using the "td" as "this".

**Edit:**I am able to capture the "td" element through using the "alert" command and it worked. So for some reason the "tip" function doesn't work. Anyone know why this would be?

Answer 1

$(this).mouseover(function() {
    tip(tTip);
});

a better way might be to put title attributes in your HTML. That way, if someone has javascript turned off, they'll still get a tool tip (albeit not as pretty/flexible as you can do with jQuery).

<table id="myTable">
    <tbody>
        <tr>
            <td title="Tip 1">Cell 1</td>
            <td title="Tip 2">Cell 2</td>
        </tr>
    </tbody>
</table>

and then use this code:

$('#myTable td[title]')
    .hover(function() {
        showTooltip($(this));
    }, function() {
        hideTooltip();
    })
;

function showTooltip($el) {
    // insert code here to position your tooltip element (which i'll call $tip)
    $tip.html($el.attr('title'));
}
function hideTooltip() {
    $tip.hide();
}
