问题描述
我已经搜索了这个问题的答案，但无法找到一个方法。
I've searched an answer to this question but can't get a way how to do it.
我想访问一个div的内容，我已经包含在一个对象标签中。
I want to access the content of a div that I have included in an object tag.
我的include.htm文件：
My include.htm file:
<div id="includedDiv">This is the included page</div>
我尝试过：
<html>
<head>
<title>Get element from object included page</title>
</head>
<body>
<p>Test: This is the main page</p>
<object id="obj" data="include.htm"></object>
<script>
//alert(document.getElementById("includedDiv").firstChild.nodeValue);
//alert((document.getElementById("obj")).document.getElementById("includedDiv").firstChild.nodeValue);
alert(document.getElementById("obj")["includedDiv"]);
</script>
</body>
</html>
没有一个警告打印出我的消息这是包含的页面，有没有办法从DOM获取此内容？
None of the alert prints me the message "This is the included page", is there a way to get this content from the DOM?
编辑：
window [0] .document.getElementById（includedDiv）。firstChild.nodeValue;是通过DOM访问的好答案，对象标签只是创建另一个窗口:)
推荐答案
更好的答案：你可以通过DOM访问对象标签内容，它只是另一个窗口！
Even better answer: you CAN access object tag content through the DOM, it is just another window!
window[0].document.getElementById("includedDiv").firstChild.nodeValue;
就是这样：D
