Question

I need to remove a class from any place withing a table if another class is not found inside a span that is residing inside that table.

Basically I need to do the opposite of hasClass but I’m not sure what I’m doing wrong. Here’s my code:

if ($("#nyTable").find("span").not("ui-icon-triangle-1-s")) {
    $("#nyTable").find("td").removeClass("redText");
}

<table>
<tr>
    <td>as</td>
    <td>asd</td>
    <td>werwe</td>
</tr>
<tr>
    <td><span class="ui-icon-triangle-1-s">asd</span></td>
    <td><span class="ui-icon-triangle-1-s">asd</span></td>
    <td><span class="ui-icon-triangle-1-s">asd</span></td>
</tr>
</table>

UPDATE: I need to make sure that this class .ui-icon-triangle-1-s does not exist anywhere in the table.

Answer 1

if (!$("#nyTable span.ui-icon-triangle-1-s").length) {
    $("#nyTable td.redText").removeClass("redText");
}
