Jquery - 从 iframe 访问父窗口的元素

我有一页我们可以打parent.php.在这个页面中，我有一个iframe和一个提交表单，除此之外，我还有一个id为"target"的div.是否可以在iframe中提交表单，并在成功时刷新目标div.比如在其中加载新页面或其他内容？

Edit: The target div is in the parent page, so my question is basically if you can make for an example a jQuery call outside the iframe to the parent. And how that would look?

编辑2:

$(;"form[name=my_form]").submit(function(e){     
 e.preventDefault; 
 window.parent.document.getElementById('#target'); 
 $("#target").load("mypage.php", function() { 
 $('form[name=my_form]').submit(); 
 }); 
 })

I don't know if the script is active cause the form submits successfully but nothing happens to target.

Edit 3:

Now I'm trying to call the parent page from a link within the iframe. And no success there either:

<a href="javascript:window.parent.getElementById('#target').load('mypage.php');">Link</a>
