Question

I have a table on my page html :

<table id="myTab">
    <tr>
        <td class="reference">1</td>
        <td>item1</td>
        <td>Info item - 1</td>
    </tr>
    <tr>
        <td class="reference">2</td>
        <td>item2</td>
        <td>Info item - 2</td>
    </tr>
    <tr>
        <td class="reference">3</td>
        <td>item3</td>
        <td>Info item - 3</td>
    </tr>
    <tr>
        <td class="reference">4</td>
        <td>item4</td>
        <td>Info item - 4</td>
    </tr>
<table>

How I can select an element of my table with class reference innerHtml value=3?

var el = $(myTab).find('???')

Answer 1

Assuming you want a reference to just that td element, and the markup you’ve shown is the extent of your current structure, you can use the :contains selector:

var elem = $(".reference:contains('3')");

If you have other td elements containing the character 3 (e.g. 13) they will also be matched. In that case, it’s probably better to use the .filter() method:

var elem = $(".reference").filter(function () {
    return $(this).text() === "3";
});
