<div id="div1">

<input type="button" id="btn1" value="alert" onclick="alertdiv()" />

<ul>

<li><a href ="#" id ="a1">gmail</a></li>

</ul>

</div>

 

 

<input type="button" id="show" value="Disable" onclick="disablediv()" />

Plaese any one tell me how to enable all anchor tag after  event.preventDefault();
