Ajax not working with wunderground API (A Weather

Hello there!.

I am trying to use a public api from wunderground (more info in [http://wiki.wunderground.com/index.php/API_-_XML][1]) on a web page (in fact in a widget for a phone, but for testing purposes, but is the same technically speaking and writing code).

The main question is that i haven't been able to get the ajax request work, i try using a plain request (without any library) and request using jquery; as you can guess: no one works.

I am getting really frustrating with this. I know there is ton of info ajax, but unfortunately i only get more frustrating understanding less i doesn't find one concrete answer over a sea of information (like the internet).

Maybe one charity soul :) can help me, i copy paste the code: is to simple to only see and for test you only have to copy and paste.

Well that is all, thanks to all!. Grettings. Víc

what you can do is

1 create a server side proxy

2 call the proxy through ajax and the proxy will in turn call the weather service

3 get the xml response form the proxy

4 parse it and display it

here is how you do it in php

create a file weather.php and put the following code in it

<?php
header('Access-Control-Allow-Origin: *');
$url = "http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=SABE";
$str = file_get_contents($url);
echo $str;
?>

call weather.php from the client side like

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.min.js"></script>
<script type="text/javascript">
$(function(){
$.ajax({
    type:'GET',  
    url:'path/to/weather.php',  
    cache:false,
    dataType:'html',
    success:function(data){         
     xmlDoc = $.parseXML(data),
     $xml = $(xmlDoc),
     $credit = $xml.find('credit').text();
     alert($credit); // alerts Weather Underground NOAA Weather Station
    },
    error:function(jxhr,e){
        console.log(jxhr.status);
        console.log(e.responseText);
    }
});

});

</script>

On the front end, you can use a callback, heres my way of grabbing stations using the WU search:

var get_city_list =  function(query) {
    $.ajax({
        url: "http://autocomplete.wunderground.com/aq?cb=cb_func&query=" + query,
        type: "GET",
        dataType: "jsonp",
        callback: "cd_func"
    });
}

    window.cb_func = function(result) {
    $.each(result, function(indexInArray, value) {
        $.each(value, function(idx, result) {
            $("<li>")
            .data("name", result.name)
            .addClass("weather-station")
            .text(result.name)
            .appendTo("#search-results");
        });
    });
}
