Something like this:
var iframe = document.getElementById('iframeId');
var innerDoc = iframe.contentDocument || iframe.contentWindow.document;
var input = innerDoc.getElementById('frame_text');
First you get the the iframe. Then you get the first valid dom document from inside the iframe.
And finaly get the input box.

<!DOCTYPE html>
<html>
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<script type="text/javascript">
function getIframeText() {
var iframe0 = document.getElementById("iframe0");
var iframe0document=iframe0.contentDocument||iframe0.contentWindow.document;
var inputIframe = iframe0document.getElementById("frame_text");
alert(inputIframe.value);
}
</script>

If you have Div/ input as follows in one Iframe
<iframe id="ifrmReportViewer" name="ifrmReportViewer" frameborder="0" width="980"
<div id="EndLetterSequenceNoToShow" runat="server"> 11441551 </div> Or
<input id="txtSequence" type="text" value="10500101" />
<form id="form1" runat="server">
<div style="clear: both; width: 998px; margin: 0 auto;" id="divInnerForm">
Some Text
</div>
</form>
</iframe>
Then you can find the text of those Div using the following code
var iContentBody = $("#ifrmReportViewer").contents().find("body");
var endLetterSequenceNo = iContentBody.find("#EndLetterSequenceNoToShow").text();
var txtSequence = iContentBody.find("#txtSequence").val();
var divInnerFormText = iContentBody.find("#divInnerForm").text();
I hope this will help someone.

Here is parent page code (I mean main page call to iframe ):
<script>
function frameClick(string){
var name=string;
document.getElementById("parent_text")=name;
}
</script>
<div>
<iframe src="test.html" id="frame1">
<input type=text id="parent_text">
</div>
Here is iframe code(test.html):
<form method="post" action="" id='frm1' >
<input type="text" id="frame_text">
<input type="button" id="btm1" name="hangup" onclick="parent.frameClick(this.form.frame_text.value);" value="submit">
</form>
