I have JSP page with `method = POST` and `action='/mydir/mypage/nextpage'`

I have a button:

```
<button title='Continue' onclick="this.form.perform.value='cancelButton'; javascript:doCloseWindow();">Continue</button>

```

and JavaScript method like:

```
function doCloseWindow(){         
  location.href = "https://abc.xyz.com/mydir/?param=123";              
}

```

It does not work in Firefox 3.6. On click of button; it redirects to the path I mentioned in form action.

With Tamper data I find that the request goes to URL (as in method) with GET and then it redirects to form's action URL.

I added return false in the method call also -- `javascript:doCloseWindow();**return false**` 

I tired various combinations like 

```
window.location.href = "https://abc.xyz.com/mydir/?param=123";
window.document.location.href = "https://abc.xyz.com/mydir/?param=123";
document.location.href = "https://abc.xyz.com/mydir/?param=123";

```

But no success.
