How to add this as html in page

Question

This a data am getting in a ajax call. Its supposed to be html. How can I add this in a div as html? I think the chars are returned in safe format. Is there a way to print it either by javascript or php?

Answer 1

The characters are returned in an escaped unicode format. You can encode it as UTF8 with this function:

function encode_utf8( s )
{
  return unescape( encodeURIComponent( s ) );
}

For example:

encode_utf8( '\u003Cscript type=\u0022text\/javascript\u0022\u003E' ); -> '<script type="text/javascript">'

Answer 2

There are 4 search/replaces you'll need to do (by my count) in order to sanitize the input string so that it can be converted to HTML and a fifth one to make it a little more readable. In no particular order:

.replace('\n', '')                  // Removes all encoded newline characters
.replace('\t', '')                  // Removes all encoded tab characters
.replace(/(?:\s+)?<(?:\s+)?/g, '<') // Removes any whitespace before or after a tag-start delimiter.
.replace(/(?:\s+)?>(?:\s+)?/g, '>') // Removes any whitespace before or after a tag-stop delimiter.
.replace(/\s+/g, ' ')               // Replaces all instances of whitespace with a single space. Enhances readability.

Once these are done, you can unescape the string and insert it somewhere in your document:

var normalizedData = data.replace('\n', '').replace('\t', '').replace(/(?:\s+)?<(?:\s+)?/g, '<').replace(/(?:\s+)?>(?:\s+)?/g, '>').replace(/\s+/g, ' ');
document.getElementById('someElement').innerHTML = unescape(normalizedData);
