Access Denied using iFrame with jQuery in IE

I’m trying to access the html in an iFrame with jQuery. I’m getting Access Denied in IE 11 and it’s not working in other browsers. The jQuery code and the iFrame page reside on the same domain. Also, this is a Dnn site if that matters.

The code below is how I’m testing, just trying to change the color of a button.

Any suggestion?

Thanks!

JQuery Code:

var frm = $("iframe").contents();
frm.find(".ppButton").css("background-color","red")

Open in new window


iFrame Form Code:

<form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="xxxx">
<table class="ppTable">
    <tr>
        <td>
            <select name="os0"  class="ppDropDown">
                <option value="Orange">Orange </option>
                <option value="Red">Red</option>
           </select>
        </td>
        <td>
            <input class="ppButton" type="submit" border="0" name="submit" value="Add to Cart" style="color: white;
                background-color: #FF8429; border: 1px solid #FF8429" />
        </td>
    </tr>
</table>

If the URL of the iframe is different from the parent page you cannot access it.

Even if there is a slight difference in the iframe url e.g. www.mysite.com and the iframe url is mysite.com then they are different domains
