if it is cross domain, you cannot get the data.

I have taken div and bind the iframe to that div
<div id="payframe"><iframe id="vantiv-payframe" name="vantiv-payframe" frameborder="0" src="page.html" height="200px" width="100%"></iframe></div>

from that i have to get id and show images

the ifram texbox is
</html>
<body>

<input type="text" id="accountNumber" maxlength="19" autocomplete="off" tabindex="1" placeholder="Account Number">

</body></html>

run this code in chrome console window and check
$("iframe").contents().find("#accountNumber");

DGKumar 21-Jun-16 6:33am

$("iframe#myframe").load(function () {
alert("hi");
var iframecontent = $("iframe#myframe").contains().find("#txtaccountNumber").val;

$("#btn").click(function () {
alert("The paragraph was clicked.");
});
