HTML form: Add parameters to action value

[Gameone]

Hello,
In a Struts2 form I have something like this:

<s:form action="myForm_view" name="MyForm" >
 <s:textfield name="searchPhrase"/>
 .....
</s:form>

When something is entered in textfield and you hit enter key, the form submits to myForm_view.action. How do I add a parameter to the action in this case? I need something like myForm_view.action?arg=1.

Please help. Thanks in advance.

<input type="hidden" name="arg" value="1">
