Been trying my best to understand this correctly. What is the difference between an XML, SOAP and JSON response? And how does one know how to call a web service whose response i

Answer 1

I have used this web service before. It expects and returns XML. Here's the code I used to get to work in Internet Explorer (For Firefox you need to use the jsonp).

$('#Currency').bind('change', function() {
    var targetDiv = '#Result'
    var currencyValue = $('#Currency option:selected').val();
    var webMethod = 'http://www.webservicex.net/CurrencyConvertor.asmx/ConversionRate';
    var parameters = "?FromCurrency=GBP&ToCurrency=" + currencyValue;

    $(targetDiv).html('loading...');

    $.ajax({
        type: "GET",
        url: webMethod + parameters ,
        contentType: "text/xml; charset=utf-8", 
        dataType: "xml", //for Firefox change this to "jsonp"
        success: function(response) {
            $(targetDiv).html(response.text);
        },
        error: function(xhr, textStatus, errorThrown) {
            $(targetDiv).html("Unavailable: " + textStatus);
        }
    });
)};
