Html code as IFRAME source rather than a URL
Solution 1:
You can do this with a data URL. This includes the entire document in a single string of HTML. For example, the following HTML:
<html><body>foo</body></html>
can be encoded as this:
data:text/html;charset=utf-8,%3Chtml%3E%3Cbody%3Efoo%3C/body%3E%3C/html%3E
and then set as the src attribute of the iframe. Example.
Edit: The other alternative is to do this with Javascript. This is almost certainly the technique I'd choose. You can't guarantee how long a data URL the browser will accept. The Javascript technique would look something like this:
var iframe = document.getElementById('foo'),
iframedoc = iframe.contentDocument || iframe.contentWindow.document;
iframedoc.body.innerHTML = 'Hello world';
Example
Edit 2 (December 2017): use the Html5's srcdoc attribute, just like in Saurabh Chandra Patel's answer, who now should be the accepted answer! If you can detect IE/Edge efficiently, a tip is to use srcdoc-polyfill library only for them and the "pure" srcdoc attribute in all non-IE/Edge browsers (check caniuse.com to be sure).
<iframe srcdoc="<html><body>Hello, <b>world</b>.</body></html>"></iframe>
Solution 2:
use html5's new attribute srcdoc (srcdoc-polyfill) Docs
<iframe srcdoc="<html><body>Hello, <b>world</b>.</body></html>"></iframe>

Solution 3:
According to W3Schools, HTML 5 lets you do this using a new "srcdoc" attribute, but the browser support seems very limited.
Solution 4:
iframe srcdoc: This attribute contains HTML content, which will override src attribute. If a browser does not support the srcdoc attribute, it will fall back to the URL in the src attribute.
Let's understand it with an example
<iframe
name="my_iframe"
srcdoc="<h1 style='text-align:center; color:#9600fa'>Welcome to iframes</h1>"
src="https://www.birthdaycalculatorbydate.com/"
width="500px"
height="200px"
></iframe>
Original content is taken from iframes.
Solution 5:
I have a page it loads an HTML body from MYSQL I want to present that code in a frame so it renders it self independent of the rest of the page and in the confines of that specific bordering.
An object with a unencoded dataUri might have also fit your need if it was only to load a portion of data text:
The HTML
<object>element represents an external resource, which can be treated as an image, a nested browsing context, or a resource to be handled by a plugin.
body {display:flex;min-height:25em;}
p {margin:auto;}
object {margin:0 auto;background:lightgray;}<p>here My uploaded content: </p>
<object data='data:text/html,
<style>
.table {
display: table;
text-align:center;
width:100%;
height:100%;
}
.table > * {
display: table-row;
}
.table > main {
display: table-cell;
height: 100%;
vertical-align: middle;
}
</style>
<div class="table">
<header>
<h1>Title</h1>
<p>subTitle</p>
</header>
<main>
<p>Collection</p>
<p>Version</p>
<p>Id</p>
</main>
<footer>
<p>Edition</p>
</footer>'>
</object>But keeping your Iframe idea, You could also load your HTML inside your iframe tag and set it as the srcdoc value.You should not have to mind about quotes nor turning it into a dataUri but only mind to fire onload once.
The HTML Inline Frame element (
<iframe>) represents a nested browsing context, embedding another HTML page into the current one.
Both iframe below will render the same, one require extra javascript.
example loading a full document :
body {
display: flex;
min-height: 25em;
}
p {
margin: auto;
}
iframe {
margin: 0 auto;
min-height: 100%;
background:lightgray;
}<p>here my uploaded contents =>:</p>
