POjavascript SOAP xmlhttprequest issue mobile
text
Body
copied!<p>All right, so previously I asked... SOAP Prototype AJAX SOAPAction Header Question (can't hyperlink it unfortunately, not enough rep for "2" links... see below)</p> <p>Which never worked out. I think it has something to do with Prototype, it will return a 0 as onSuccess. I can't figure out the Content-type utf-8 formatting. Now if I go back to straight javascript and use xmlhttprequest</p> <pre><code><html xmlns="http://www.w3.org/1999/xhtml"> </code></pre> <p> </p> <pre><code> function getUVIndex() { // In Firefox, we must ask the user to grant the privileges we need to run. // We need special privileges because we're talking to a web server other // than the one that served the document that contains this script. UniversalXPConnect // allows us to make an XMLHttpRequest to the server, and // UniversalBrowserRead allows us to look at its response. // In IE, the user must instead enable "Access data sources across domains" // in the Tools->Internet Options->Security dialog. if (typeof netscape != "undefined") { netscape.security.PrivilegeManager. enablePrivilege("UniversalXPConnect UniversalBrowserRead"); } // Create an XMLHttpRequest to issue the SOAP request. This is a utility // function defined in the last chapter. var request = new XMLHttpRequest(); // We're going to be POSTing to this URL and want a synchronous response request.open("POST", "http://iaspub.epa.gov/uvindexalert/services/UVIndexAlertPort?wsdl", false); request.onreadystatechange=function() { if (request.readyState==4) { var index = request.responseXML.getElementByTagName('index')[0].firstChild.data; alert(request.responseText); } } // Set some headers: the body of this POST request is XML request.setRequestHeader("Content-Type", "text/xml"); // This header is a required part of the SOAP protocol request.setRequestHeader("SOAPAction", '""'); // Now send an XML-formatted SOAP request to the server request.send( '<?xml version="1.0" encoding="utf-8"?>' + '<soap:Envelope' + ' xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"' + ' xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"' + ' xmlns:tns="urn:uvindexalert" xmlns:types="urn:uvindexalert/encodedTypes"' + ' xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"' + ' xmlns:xsd="http://www.w3.org/2001/XMLSchema">' + ' <soap:Body soap:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">' + ' <tns:getUVIndexAlertByZipCode>' + ' <in0 xsi:type="xsd:string">12306</in0>' + ' </tns:getUVIndexAlertByZipCode>' + ' </soap:Body>' + '</soap:Envelope>' ); // If we got an HTTP error, throw an exception if (request.status != 200) throw request.statusText; //return request.responseXML.childNodes[0].childNodes[1].childNodes[3].childNodes[5].textContent; } getUVIndex(); </script> </code></pre> <p></p> <p></p> <p> </p> <p>This never calls the onreadystatechange. If you uncomment the return request.responseXML.childNodes[0].childNodes[1].childNodes[3].childNodes[5].textContent;</p> <p>It will retrieve the value needed and if you are in Firebug you will see the readyState == 4 and status == 200 (not that I check for that). I usually never need to be spoon fed but I just don't understand why I am not getting the values back I need from the listener, or why it is never called. Also, not that this should matter really but I am approving the request on Firefox to be cross-domain, it is really for mobile so the call will not need to be have a confirmation of cross-domain, it will do that automatically.</p> <p>I hope someone can look at this and see what I overlooked. Thanks!</p>
