and in func() I have an alert("hereee") but when I click it, it shows "hereee" in an alert window. But it also refreshes the page as well. How to prevent page refresh onclick event?

Can anyone help?

Use return false to prevent the page refresh.

<s:submit type="input" value="clickme" onclick="func(); return false;"/>
