用jquery替换onsubmit

<form name="submissions" action="/" onsubmit="window.open('', 'foo', 'width=900,height=900,status=yes,resizable=yes,scrollbars=yes')" target="foo" method="post">
.......
<input type="submit" id="printbtn" name="printbtn" value="Print" />
<input type="submit" id="editbtn" name="editbtn" value="Edit" />
</form>

*已编辑*

window.open只应在单击“打印”按钮时发生.
我想删除onsubmit()事件并使用jQuery执行此操作.我该怎么做？

$('form[name="submissions"]').submit(function(event){
     event.preventDefault();
     // Do other stuff   
});

更新：实际上,试试这个……

$(function(){
    $('form[name="submissions"]').removeAttr('onsubmit')
        .submit(function(event){
            event.preventDefault();
                    // This cancels the event...
        });
    // This should fire your window opener...
    $('#printbtn').click(function(){
        window.open('', 'foo', 'width=900,height=900,status=yes,resizable=yes,scrollbars=yes');
    })

});

应该删除onsubmit,并阻止表单提交…
