My Iframe looks like this
<iframe id="myId" class="af_richTextEditor_content-input" frameborder="0" style="height: 36em;" src="/blank.html">
<html>
<head>
<title></title>
</head>
<body dir="ltr" style="margin: 0px; padding: 1px; font-size: small; font-family: Tahoma,Verdana,Arial,Helvetica,FreeSans,sans-serif; -moz-box-sizing: border-box;">
myText
<br>
MySecondText
</body>
</html>
</iframe>
This iframe behaves like textarea (it is like input field) and I can write text into it and select some text inside. Now When button is pressed I want to get selected area (start position and end position of body tag selection). How to? JQuery? Pure JS? Examples?
