How to set HTML content into an iframe
I have a HTML string
<html>
<body>Hello world</body>
</html>
and I want to set it to an iframe with JavaScript. I am trying to set the HTML like this:
contentWindow.document.body.innerHTML
or
contentDocument.body.innerHTML
or
document.body.innerHTML
but IE gives "Access is denied." or "Object does not support this property or method." or "Invalid final element to the action." errors.
Here is my full code:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="jquery_1.7.0.min.js"/>
<script type="text/javascript">
$(document).ready(function(){
var htmlString = "<html><body>Hello world</body></html>";
var myIFrame = document.getElementById('iframe1');
// open needed line commentary
//myIFrame.contentWindow.document.body.innerHTML = htmlString;
//myIFrame.contentDocument.body.innerHTML = htmlString;
//myIFrame.document.body.innerHTML = htmlString;
//myIFrame.contentWindow.document.documentElement.innerHTML = htmlString;
});
</script>
</head>
<body>
<p>This is iframe:
<br>
<iframe id="iframe1">
<p>Your browser does not support iframes.</p>
</iframe>
</body>
</html>
Solution 1:
You could use:
document.getElementById('iframe1').contentWindow.document.write("<html><body>Hello world</body></html>");
Here's a jsFiddle, which works in all major browsers.
Note that instead of contentDocument.write you should use contentWindow.document.write: this makes it work in IE7 as well.
Solution 2:
var htmlString="<body>Hello world</body>";
var myIFrame = document.getElementById('iframe1');
myIFrame.src="javascript:'"+htmlString+"'";
With html5 you'll be able to use the srcdoc attribute.
Solution 3:
The innerHTML is a bit tricky especially in IE, where elements like thead are read-only and cause a lot of trouble.
Based on the documentation on msdn you might try documentMode which provides a innerHTML property.
myIFrame = myIFrame.contentWindow ||
myIFrame.contentDocument.document ||
myIFrame.contentDocument;
myIFrame.document.open();
myIFrame.document.write('Your HTML Code');
myIFrame.document.close();
this might only work in IE.

Solution 4:
I have a problem with 'origin' with the answers here. This is how it's work for me:
const frame1 = document.createElement('iframe');
frame1.name = 'frame1';
//not have to set this style,just for demo
frame1.style.position = 'absolute';
frame1.style.height = '800px';
frame1.style.top = '100px';
frame1.style.left = '100px';
frame1.style.background = 'white';
document.body.appendChild(frame1);
const frameDoc =
frame1.contentWindow || frame1.contentDocument.document ||
frame1.contentDocument;
frameDoc.document.write('<html><head><title></title><body>Hello world</body></html>');
frameDoc.document.close();
