Show me the code! – By Davanum Srinivas

Sample to call the web service documented here:

jQuery.ajax makes it real simple to do a SOAP 1.2 call and to parse the response xml as well.

Here’s the source code:

var noun_type_zip = {
    _name : "zip",
    suggest: function(fragment) {
        var regexp = /(^\d{5}$)|(^\d{5}-\d{4}$)/;
        if (regexp.test(fragment)) {
            return [CmdUtils.makeSugg(fragment)];
        }
        return [];
    }
};

CmdUtils.CreateCommand({
    name: "weather-by-zip",
    takes: {"zip code": noun_type_zip},
    execute: function(directObj) {
    },

    preview: function(pblock, directObj) {
        payload = '<soap:Envelope xmlns:soap="http://www.w3.org/2003/05/soap-envelope" ' +
                  '               xmlns:weat="http://ws.cdyne.com/WeatherWS/"> ' +
                  '    <soap:Body> ' +
                  '        <weat:GetCityWeatherByZIP> ' +
                  '            <weat:ZIP>' + directObj.text + '</weat:ZIP> ' +
                  '        </weat:GetCityWeatherByZIP> ' +
                  '     </soap:Body> ' +
                  '</soap:Envelope> ';
        jQuery.ajax({
            type:     'POST',
            url:      "http://ws.cdyne.com/WeatherWS/Weather.asmx",
            dataType: "xml",
            data:     payload,
            beforeSend: function(req) {
                req.setRequestHeader("Content-Type", 'application/soap+xml;charset=UTF-8;action="http://ws.cdyne.com/WeatherWS/GetCityWeatherByZIP"');
            },
            success: function(xml) {
                var el = jQuery(xml).find("GetCityWeatherByZIPResult");
                pblock.innerHTML = "<p><table>" +
                                   "<tr><td> State </td><td>" + el.find('State').text() + "</td>" +
                                   "<tr><td> City </td><td>" + el.find('City').text() + "</td>" +
                                   "<tr><td> WeatherStationCity </td><td>" + el.find('WeatherStationCity').text() + "</td>" +
                                   "<tr><td> Description </td><td>" + el.find('Description').text() + "</td>" +

                                   "<tr><td> Visibility </td><td>" + el.find('Visibility').text() +  "</td>" +
                                   "<tr><td> WindChill </td><td>" + el.find('WindChill').text() +  "</td>" +
                                   "</table></p>" ;
            },
            error: function() {
                displayMessage('ERROR: SOAP call failed!');
            }
        }, "xml");
    }
