How can I add/remove an element to/from the first td of the table before text?

I have a div with id (titlediv_1265601). How can I add/remove a * to the first td of the table before "Adjuster Name:" based on the following condition using jquery?

        if(a == 'addSpan')
        {}
        else if(a == 'RemoveSpan')
        {}
<div id="titlediv_1265601" style="width: 100%; position: relative; visibility: visible; display: block;">
            <table> 
                <tbody>
                    <tr>
                        <td id="AdjusterOrAdjusterAssistantCell" class="MyTableHeadingCell">A开发者_StackOverflow中文版djuster Name:</td>
                        <td class="MyTableTagsCell"><input type="text" id="AdjusterOrAdjusterAssistant"></td>
                        <td class="MyTableHeadingCell"></td>
                         <td class="MyTableTagsCell"></td>
                    </tr>
                </tbody>
            </table>
        </div>

$("#AdjusterOrAdjusterAssistantCell")
       .prepend('<span class="Required" title="Required">* </span>');

will probably work correctly.

If I understood you correctly: You can use the :first-child pseudo selector to access the first <td> in the table, and then jQuery's prepend()` to prepend your desired content.

$('#titlediv_1265601 table td:first-child').prepend('<span class=“Required” title=“Required”>* </span>');

To add:

$("#AdjusterOrAdjusterAssistantCell").prepend('<span class="Required" title="Required">*</span>');

To remove:

$("#AdjusterOrAdjusterAssistantCell span").remove();
