<div class="content wysiwyg-content">
 I have a checkbox <br />
<br />
&lt;input name=&quot;mycheck&quot; type=&quot;checkbox&quot; value=&quot;1&quot; id=&quot;mycheck&quot; /&gt;<br />
<br />
I want to call a hideinfo function &nbsp;(if it is not selected) &nbsp; or showinfo function (if checkbox value is selected). &nbsp;I need to call a function, not show a div as I am using this with canvas.<br />
<br />
So it should be if checkbox is selected (has 1) then run showinfo()<br />
&nbsp;if checkbox is not selected &nbsp;then run hideinfo()
</div>
</div>
