in Getting Started
•
6 years ago
Hallo, i'm receiving async a string that is a file name like
"shirts.jpg" in this way
var image = $(this).children("image").text();
But i've an error in that variable and I think the problem is that
the variable contains A DOT, which make think to JS is a class.
I just need to store in the variable the string like
"shirts.jpg". Any idea bout it?

Does your XML look like
…
<image>shirts.jpg</image>
…
?
Could you share how you get this async string?

Yes, my XML looks like your example.
$.ajax({
type: "POST",
url: "../API/1.0/list.php",
data: { mac: MAC, cat: cat,
latitude: latitude, longitude: longitude, time_zone: time_zone,
order: order},
cache: false,
success: xmlParser
});
function xmlParser(xml) {
$('#promolist').html('');
$(xml).find('promo').each(function () {
var id = $(this).attr("id");
var name = $(this).children("name").text();
var desc = $(this).find("desc").text();
var promo_mess = $(this).find("promo_mess").text();
var image = $(this).children("image").text();
var shop_id = $(this).find("shop").attr("id");
var shop_name = $(this).find("shop>name").text();
var shop_latitude
= $(this).find("shop>latitude").text();
var
shop_longitude = $(this).find("shop>longitude").text();
var distance = $(this).find("shop>distance").text();
$('#promolist').append('<li><a id="'+id+'"
href=""><img
src="http://www.fancyroad.com/upload/promo/icon/'+image+'"
/><h3>'+name+'</h3><p>'+promo_mess+' | '+distance+'</p></a></li>');
$('#promolist').listview('refresh');
});
}
All other strings work properly. I get problem only with the image
file name

Are you sure the error is coming from that? It looks innocuous. Do
you get a better line number of the problem in another browser?

Is it possible that fancy road is redirecting you? Try it with
your own site.

Hi, click on "Uomo" (man) and then on "Scarpe"
(shoes). You'll arrive on the list.php page that contains the list with
"broken" image.

Your XML is not served properly. Strange things happen when you call $(xml).
Your <image> tag is converted to an <img> tag!
var image = $(this).children("image").text();
doesn’t find anything!
Did you use proper XML headers in your PHP?

Hi, XML headers are optional.
This is an example of how the XML is correctly served. The tag
<image> doesn't change... in the ajax query, the dataType is
guessed and every vars work correctly but not this one...

When I inspect the page in Safari , it has a <html> tag and
<head> and <body> and the <image> tags are gone and
replaced with <img> tags.
Whoever told you that XML headers are optional was foolish or lying.

Re: Get a string variable with dot

Dear man,
I added the correct header <?xml
version="1.0" encoding="UTF-8"
standalone="yes" ?>. But nothing changed, i tried to put
the info of image file in the Attribute file like <image
file="shoes.jpg"></image>, but i got the same error.
Then, i changed the name to "imma" gettins this:
<imma>shoes.jpg</imma>... and everythink work correctly!
The mistake seems is caused by <image> is not accepted... why???

<?xml version="1.0"
encoding="UTF-8" standalone="yes" ?>
is
not the header I am looking for.
I want something like
- <?php
- header ("Content-Type:text/xml");
or
- <?php
- header('Content-Type: application/xml; charset=utf-8');

Re: Get a string variable with dot

You are right that
<?xml version="1.0" encoding="UTF-8"?>is optional. I guess people call that a "header" sometimes.

Re: Get a string variable with dot

^ It's called an "XML Declaration".
A more proper name for "headers" is "HTTP
Headers". HTTP is the protocol used to transport documents from
the server to the client. It has headers and a body. The body contains
the document. Headers tell the browser (among other things) what kind
of data the body carries (HTML, JPG, JSON, XML, etc. etc. etc.)
An XML document has an optional XML Declaration.
If the header specifying what kind of document is in the body,
the browser has to guess. Sometimes it doesn't guess correctly.
<image> is an
anachronism. It's still supported by many browsers because an early
Netscape version supported <image> as a
synonym for <img>. It stuck to
the extent that other browsers had to support it to keep from
"breaking the web". Your browser helpfully corrected what
looked like a fixable error in what it thought was an HTML document.

Browsers never guess. Only HTTP headers that set
content-type to a valid XML type cause the browser to
create responseXML which is used by jQuery. If it’s not XML you
only get responseText. Which does not parse into XML unless
you force it with $.parseXML().
And that’s what the problem was.

Your browser guessed HTML. The normal presentation of an octet-stream in most browsers would be plain text. You would see the actual tags.Any HTTP/1.1 message containing an entity-body SHOULD include a Content-Type header field defining the media type of that body. If and only if the media type is not given by a Content-Type field, the recipient MAY attempt to guess the media type via inspection of its content and/or the name extension(s) of the URI used to identify the resource. If the media type remains unknown, the recipient SHOULD treat it as type "application/octet-stream".
Re: Re: Get a string variable with dot

An XMLHttpRequest
does not come in as html. jQuery does that part. the browser gives
you text or xml and text.
If
you specify dataType XML in the jQuery request and you have omitted
an XML content type header, jQuery parses the text and returns the
XML. Faking it out very nicely for you.
dataType (default:
Intelligent
Guess (xml, json, script, or html))Type: String
The
type of data that you're expecting back from the server. If none
is specified, jQuery will try to infer it based on the MIME
type of the response (an XML MIME type will yield XML, in
1.4 JSON will yield a JavaScript object, in 1.4 script will
execute the script, and anything else will be returned as a
string). The available types (and the result passed as the first
argument to your success callback) are: …
