javascript - xhrPost 与 Firefox 和 IE8 的工作方式不同——但我如何处理响应？

Question

我真的不明白为什么我从带有 Dojo 的 xhrPost 得到不同的响应。对于 IE8，它工作正常并且可以读取 XML - 但在 Firefox 中它的工作方式不同并且没有“serverResponse.results[0].xml”这样的属性 - 见下文:

var serverResponse = dojo.xhrPost(xhrArgs);
serverResponse.results[0].xml

就像您在 IE8 中一样。

有谁知道在使用 xhrPost 时如何在 Firefox 中正确处理响应。干杯。

var message = '<?xml version="1.0" encoding="utf-8"?>' +
                    '<soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope">' +
                      '<soap12:Body>' +
                        '<MineSearch xmlns="http://localhost/">' +
                          '<x>' + inPoint.x + '</x>' +
                          '<y>' + inPoint.y + '</y>' +
                          '<buffer>' + buffer + '</buffer>' +
                        '</MineSearch>' +
                      '</soap12:Body>' +
                    '</soap12:Envelope>';




        //The parameters to pass to xhrPost, the message, and the url to send it to
        //Also, how to handle the return and callbacks.
        var xhrArgs = { url: "http://localhost/ApplicationServices.asmx?op=MineSearch",
            postData: message,
            headers: { "Content-Type": "application/soap+xml" },
            handleAs: "xml",
            sync: true,
            load: function(data) {
                dojo.byId("footer").innerHTML = "Message posted.";
            },
            error: function(error) {
                dojo.byId("footer").innerHTML = "Message error.";

            }
        }

        //Call the asynchronous xhrPost
        var serverResponse = dojo.xhrPost(xhrArgs);
        var xmldata = serverResponse.results[0].xml;
        var xmlDoc;

        if (window.DOMParser) {
            parser = new DOMParser();
            //Below is wrong somehow and the serverResponse.results[0] is probably wrong too.
            xmlDoc = parser.parseFromString(serverResponse.results[0], "text/xml");
        }
        else // Internet Explorer
        {
            xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
            xmlDoc.async = "false";
            xmlDoc.loadXML(xmldata);
        }

dojo.xhrPost 的返回对象是一个dojo.Deferred 对象，不应从dojo.Deferred 对象中检索响应.

如果你指定handleAs为xml，你可以直接在load函数中通过参数data获取响应的XML文档。

var xhrArgs = { url: "http://localhost/ApplicationServices.asmx?op=MineSearch",
        postData: message,
        headers: { "Content-Type": "application/soap+xml" },
        handleAs: "xml",
        sync: true,
        load: function(data) {
            //data is the XML document
        },
        error: function(error) {
            dojo.byId("footer").innerHTML = "Message error.";

        }
}
dojo.xhrPost(xhrArgs);
