1. <td id="D19" style="font-family:Arial;font-size:11px;background-color:#FFFF00;color:#000000;" onfinishinput="checkif()" contenteditable="true">Sample Content</td>

What I want is when I click a button it will add (e.g. bold, font-weight) a style attribute, then by clicking it again it will be remove (the desired style attribute),  but the style only the specific attribute of a style. Is there a process for this, cause i've been searching all I can see is toggleClass. . but I don't want to do that because each attribute has a value that I have to pass to a server side.
