I upload a file in an iframe (it seems to be no other way). As a response, I generate a JSON object where one of the fields is a line with html describing the error.
Question: How can I get this response from the server without breaking it?

When I use .text() from jQuery, all tags are removed.
When I use .html() from JQuery it "fixes" the html and after that it's not possible to deserialize the JSON because the quotes lose the escape character. we get Invalid JSON.

Try to encode urlencode on the server before sending the HTML to the client, decode it with javascript on the client via decodeURI or unescape.

How do you generate and receive json?
For data like this

{"html":"<a href=\"#\">!!!<\/a>"}

using getJSON everything shows up fine


<html>
<head>
<script type="text/javascript" src="http://yandex.st/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(document).ready(function() {
  $.getJSON('j.php', '', function (data) {$('body').html(data.html);});
}
);
</script>
</head>
<body>
</body>
</html>

give in the iframe not json, but full-fledged html + javascript:
<script>parent.callback_func({json: "data"});</script>
