Sometime we need to read and modify same domain iframe content using jQuery. Here is code snippet which will modify the content of an iframe.
<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<iframe id="iframe1" src="/demo2/ihello.html"></iframe>
<script type="text/javascript">
$(window).load(function() {
var iframeDoc = $("#iframe1")[0].contentWindow.document;
var $jqObject = $(iframeDoc).find("body");
var iframeHtml = $jqObject.html();
$jqObject.html(iframeHtml + "<br/>appended text from jquery");
});
</script>
