问题描述
我正在开发仅通过iframe引入新代码的应用程序.我正在尝试创建一个函数(在iFrame中运行)，该函数将在其中运行iFrame的后面附加一些html.我宁愿不介绍jQuery来解决此问题.这是一个示例
I'm developing in an application where new code is introduced via iframes only. I'm trying to create a function (running inside an iFrame) that will append some html after the iFrame in which it is running. I'd rather not introduce jQuery to resolve this issue. Here is a sample
function AppendDivAfteriFrame() {
var iFrame = window.parent.document.getElementById(window.frameElement.id)
var newDivInParent = window.parent.document.createElement('div');
newDivInParent.setAttribute("Id", "MyDiv");
newDivInParent.innerHTML = 'Hello World! I am outside the iFrame';
iFrame.appendChild(newDivInParent);
}
我没有收到任何例外，但是我也从未看到任何结果.
I don't receive any exceptions, but I never see any results either.
将此页面称为InnerPage.html
Call this page InnerPage.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script type="text/javascript">
function AppendDivAfteriFrame() {
var iFrame = window.parent.document.getElementById(window.frameElement.id)
var newDivInParent = window.parent.document.createElement('div');
newDivInParent.setAttribute("Id", "MyDiv");
iFrame.appendChild(newDivInParent);
parent.document.getElementById('MyDiv').innerHTML = 'Hello World! I am outside the iFrame';
}
</script>
</head>
<body>
<button onclick="AppendDivAfteriFrame()">Append HTML</button>
</body>
</html>
将此页面称为OuterPage.html
Call this page OuterPage.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
</head>
<body>
<iframe src="InnerPage.html" id="MyiFrame"></iframe>
</body>
</html>
推荐答案
这有效:
function AppendDivAfteriFrame() {
var iFrame = window.parent.document.getElementById(window.frameElement.id)
var newDivInParent = window.parent.document.createElement('div');
newDivInParent.setAttribute("Id", "MyDiv");
iFrame.parentNode.appendChild(newDivInParent); //Edited here
parent.document.getElementById('MyDiv').innerHTML = 'Hello World! I am outside the iFrame';
}
