IE6的jQuery ajax问题

Question

Hi my problem is a bit wired:

my $.ajax success handler looks like:

function(data){
        alert(data);
}

Pretty simple, yeah?

The problem is that data IS ALWAYS 3 character long - no matter what was sent by the server! The characters: 31 65535 8 (using charCodeAt()).

In other browsers (even in IE 8) all works fine.

I've looked at xhr.responseText in complete handler - just the same result.

UPDATE Full http response

UPDATE ! Well, problem temporary? solved by disabling gzip in .htaccess

Answer 1

The characters you get look weird, but could it be that it's a BOM ? It's none of the ones listed in the article, but maybe getCharCode() gets something wrong.

In that case, you would have to check the script you call to request the data. Try saving it explicitly without a BOM.

Answer 2

this is most times an problem with propper encoding of the requested content / displayed content.

Please verify that both use the same format.

Answer 3

Despite ajax is always done in UTF-8 some implementations are weird and they don't allow passing non ascii characters. You have to change them to entities.

If You pass only one character and still get problems - It might be the BOM mentioned by Pekka. You would have to save Your PHP FILE without any spaces before

Second thing is that You might be outputing something at the end of the php file.
