Passing a java variable to a javascript function

I have the following piece of code which is a input content for a js lib:

content:'<a href="x.com" onclick="confirmDel("<%=user.name%>")" > <img src="delete.png" alt="Delete" width="15px" height="15px"></a></div>'

confirmDel(name)
{
 if(confirm("delete " + name +" ?"))
   {
     // Do delete stuff
   } else
   {
   return false;
   }
}

when I click the delete link, it does not prompt me with the delete confirmation alert! what am I missing here? Is it about the way I pass the variable to the function?

confirmDel(name)
{
 if(confirm("delete " + name +" ?"))
   {
     // Do delete stuff
   } else
   {
   return false;
   }
}

This is incorrect. Its halfway between declaring a function and calling it, but doesn't really do either.

You need to declare the function and then call it to execute that code. You're calling it in the onclick section now, but you need to define it correctly

function confirmDel(nameStr)
{
 if(confirm("delete " + nameStr +" ?"))
   {
     // Do delete stuff
   } else
   {
   return false;
   }
}

 content:'<a href="x.com" onclick="confirmDel(\''+<%=user.name%>+'\')" > <img src="delete.png" alt="Delete" width="15px" height="15px"></a></div>'

problem with passing parameter in the onclick..use escape character..
