Question

我们正在使用一些代码来生成iframe宽度

$dialogFrame.width($dialogOuter.width()).height($dialogOuter.height());

输出使用CSS文件生成固定大小的iframe。当我检查元素时，这是输出：

<iframe frameborder="0" src="http://localhost/hunch/Master-Repo/testing/popupviewresponse/7/lkjlkj" style="width: 480px; height: 400px;"></iframe>

有没有办法可以将宽度/高度设置为外部CSS样式？

也许我错过了一些东西，但$('#id').addClass('yourClass');应该可以解决问题。
