I tried to use it in following way. asmx: [WebMethod] public string XmlTest([XmlAnyElement] XmlElement test) { return ""; }
js: var xmldata="<Book>a</Book> var par = { "test": xmldata}; $.ajax({ type: 'post', url: "WebService/DatabaseWS.asmx/XmlTest", processData: false, data: data, success: function() { alert('yes'); }, }, But it seems wrong, and didn't call the XmlTest method, Anyone can help me?
