How to find the index of a row in a table using jquery

Question

I'm trying to find the index of a row in a table. I'm trying to use the following code, but I seem to get an index of -1.

$(document).ready(function()
{
    $("tr").click(function (){
        var index = $("table").index($(this));
        $("span").text("That was row index #" + index);
    });
});

With html that looks like this;

<table>
<tbody>
    <tr><td>click</td></tr>
    <tr><td>click</td></tr>
    <tr><td>click</td></tr>
    <tr><td>click</td></tr>
</tbody>

Thanks

Answer 1

Have you tried:

$("tr").index(this)

The documentation shows just passing this and that the preceding selection should be where the node is found. If you need to find it in a specific table (and there are multiple), you may need to provide some context:

// haven't tested this
$("tr", $(this).closest("table")).index(this)
