Java script Validation in struts form

[unnii]

Hi Guys,

I written a function to validate on clicking Add button(submit) but the function is getting fired on clicking Add(html:submit) and Cancel(html:cancel).

i have textboox named 'categoryName' and button named 'Add' and 'cancel'

I written a javascript for a form like the following:

function checkForm(form) { 

	if (document.getElementById("categoryName").value == null
			|| document.getElementById("categoryName").value == "")
		{
		
		alert("Please enter category name"); 
		return false; 
		} 

	
	return true;

 }

and i call the function like :

<html:form action="/addCategory" method="post" onsubmit="return checkForm(this);">

i have two button called Add, Cancel as follows:

 <td><html:submit style="width:75px;" property="service" value="Add"  />     
<html:cancel style="width:75px;" value="Cancel" /></td>
