javascript - 如何获取嵌入 IFrame 的网站的主机名

Question

如何使用 jquery 获取嵌入 Iframe 的网站的主机名？例如这个 iframe

<iframe src="xyz.com/123" frameborder="0" allowtransparency="true" allowfullscreen="allowfullscreen" webkitallowfullscreen="webkitallowfullscreen" mozallowfullscreen="mozallowfullscreen" oallowfullscreen="oallowfullscreen" msallowfullscreen="msallowfullscreen" width="640" height="400"></iframe>

Answer 1

尝试类似的东西:

$("iframe").attr("src");

或者如果寻找父 URL

$(function(){
  var currentUrl = document.referrer;
  alert(currentUrl)
});
