iframe 内 Web 元素的 QuerySelector

问题描述

新标题.我正在寻找的是 iframe 内元素的 document.querySelector.

New title. What I'm looking for is a document.querySelector for elements inside an iframe.

我在谷歌上搜索了很多答案，最后我被难住了.

I've done quite a bit of Googling for an answer and finally I'm stumped.

我正在尝试在 iframe 中进行查询.我正在构建要在 Selenium 中使用的字符串选择器，通常我只是用 Firebug 检查元素，然后使用 document.querySelectorAll("theStringIBuid");

I'm trying to query inside an iframe. I'm building string selectors to be used in Selenium and usually I just inspect the element with Firebug, and use document.querySelectorAll("theStringIBuid");

但它不适用于 iframe 中的元素.我已经尝试了以下所有方法来在page-iframe"iframe 中获取一个元素radiobutton1".

But it doesn't work with elements inside iframes. I've tried all of the below to get an element "radiobutton1" inside the "page-iframe" iframe.

var elem1 = ".page-iframe";
console.log(elem1);
var elem2 = ".radiobutton1";
console.log(elem2);
document.querySelectorAll(elem1+elem2+"");

document.querySelectorAll('.page-iframe').contentWindow.document.body.querySelectorAll('.radiobutton1')
document.getElementById('.page-iframe').contentWindow.document.body.innerHTML;

[].forEach.call( document.querySelectorAll('.page-iframe'), 
function  fn(elem){ 
console.log(elem.contentWindow.document.body.querySelectorAll('.radiobutton1')); });

var contentWindow = document.getElementById('.page-iframe').contentWindow 
var contentWindow = document.querySelectorAll('.page-iframe') 
var contentWindow = document.querySelectorAll('.page-iframe')[0].contentWindow

谢谢-
