jquery mobile data-role button disabled

jquery mobile data-role button disabled

I have an image that serves as a button. This is the code:
<a href="#frmqt" onClick="s()"><img src="images/buttons/BEGINNER.png"/></a>
And what I'm trying to do is when I clicked this image, the button(which
is coded as:
<a href="#area" onClick="beginIt()" name="start" data-role="button"
data-theme="l">START</a> ) would be disabled and not functional.
Is it possible to the <a> tag with data role button would be disabled and
functional using javascript?
Any help would be appreciated. Thanks in advance.
