Magento:: Blocks HTML output issue with jquery

Sometime jquery didnot work with because of caching of bocks
here is the solution pass the parameter in your code like :

<action method="setCacheLifetime"><s>0</s></action>

<block type="page/html_topmenu" name="catalog.topnav" template="page/html/topmenu.phtml">
    <action method="setCacheLifetime"><s>0</s></action>
</block>
