javascript - 如何使用内联样式调整 javascript 生成的 iframe 的大小？

Question

我想通过调整生成的 iframe 的大小和偏移来隔离评论小部件中的 Facebook 个人资料图片。棘手的部分(或者在我看来是这样)是生成的 iframe 包含内联样式。

有人愿意帮忙吗？

我确信这违反了 TOS，但这只是为了概念证明。

这是文档: http://developers.facebook.com/docs/reference/plugins/comments/

这里是推荐的代码:

<div id="fb-root"></div>
<script>(function(d, s, id) {
    var js, fjs = d.getElementsByTagName(s)[0];
    if (d.getElementById(id)) return;
    js = d.createElement(s); js.id = id;
    js.src = "//connect.facebook.net/en_US/all.js#xfbml=1&appId=145044622175352";
    fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
<div class="fb-comments" data-href="http://stackoverflow.com" data-num-posts="1" data-width="200"></div>

这是生成的源代码:

<div class=" fb_reset" id="fb-root"><div style="position: absolute; top: -2000px;"><iframe src="http://static.ak.facebook.com/connect/xd_arbiter.php?version=4#channel=f218f99fdee7694&amp;origin=http%3A%2F%2Fstackoverflow.com&amp;channel_path=%2Fquestions%3Ffb_xd_fragment%23%3F%3D%26xd_sig%3Df978c5a2550e88%26&amp;transport=postmessage" name="fb_xdm_frame_http" id="fb_xdm_frame_http"></iframe><iframe src="https://s-static.ak.facebook.com/connect/xd_arbiter.php?version=4#channel=f218f99fdee7694&amp;origin=http%3A%2F%2Fstackoveflow.com&amp;channel_path=%2Fquestions%3Ffb_xd_fragment%23%3F%3D%26xd_sig%3Df978c5a2550e88%26&amp;transport=postmessage" name="fb_xdm_frame_https" id="fb_xdm_frame_https"></iframe></div><div style="position: absolute; top: -10000px; height: 0pt; width: 0pt;"><div><iframe src="http://www.facebook.com/dialog/oauth?api_key=145044622175352&amp;app_id=145044622175352&amp;channel_url=http%3A%2F%2Fstatic.ak.facebook.com%2Fconnect%2Fxd_arbiter.php%3Fversion%3D4%23cb%3Df75bfba58018fa%26origin%3Dhttp%253A%252F%252Fstackoverflow.com%252Ff218f99fdee7694%26domain%3Dstackoverflow.com%26relation%3Dparent.parent&amp;client_id=145044622175352&amp;display=none&amp;domain=stackoverflow.com&amp;locale=en_US&amp;origin=1&amp;redirect_uri=http%3A%2F%2Fstatic.ak.facebook.com%2Fconnect%2Fxd_arbiter.php%3Fversion%3D4%23cb%3Dfc987f035fe9c2%26origin%3Dhttp%253A%252F%252Fkidnog.dev%252Ff218f99fdee7694%26domain%3Dkidnog.dev%26relation%3Dparent%26frame%3Df209b5ae6806ada&amp;response_type=token%2Csigned_request%2Ccode&amp;sdk=joey" class="FB_UI_Hidden" style="border: medium none; overflow: hidden; height: 240px; width: 575px;" name="f2ee3a0e40436fc" id="f209b5ae6806ada" scrolling="no"></iframe></div></div></div>

您可能是对的，这很可能违反了他们的服务条款。但作为概念验证，我尝试让它发挥作用。

此解决方案似乎在用户登录时有效:http://jsfiddle.net/joshdavenport/4VaVZ/ 。但是，当用户未登录时，一个框会停止 anonymous facebook profile photo 的完全可见性。 。

Javascript 没有取得任何成功，我认为是因为一旦加载框架就会执行各种代码，从而停止修改，说实话，这很好!他们在阻止恶意代码注入(inject)方面做得很好。
