        return;
    }
    if (typeof FormData == "undefined") {
        var postdata = [];
        for (var i = 0; i < files.length; i++) {
            postdata.push("UploadedFile", files[i]);
        }
        postdata.push("TaskID", iTaskID);
    }
    else {
        var postdata = new FormData();
        for (var i = 0; i < files.length; i++) {
            postdata.append("UploadedFile", files[i]);
        }
        postdata.append("TaskID", iTaskID);
    }
    $.ajax({
        type: "POST",
        url: "TaskStatus.asmx/UploadExecTaskPic",
        contentType: false,
        processData: false,
        async: false,
        responseType: "json",
        data: postdata,
        success: function (result) {
            var MaxFile = GetSessionValuecurrent(iTaskID);
            if (MaxFile == "MaxFile") {
                alert("Maximum 3 Files only Allowed to Upload");
            }
            else {

                $("#TaskImg").val("");
                $("#TaskImg").replaceWith($("#TaskImg").clone());
                DoCloseFileSelector();
                DoShowTaskImages(iTaskID, '');
            }
        },
        error: function () {
            alert("Upload Error");
        }
    });
}
}

网络方法:

[WebMethod(EnableSession = true)]
public string UploadExecTaskPic()
{
    string sResult = string.Empty;
    return sResult;
}

FIX Request format is unrecognized for URL unexpectedly ending in

Add the following to web.config since GET and POST are disabled by default in ASP.NET 2.0 and greater:

<configuration>
    <system.web>
    <webServices>
        <protocols>
            <add name="HttpGet"/>
            <add name="HttpPost"/>
        </protocols>
    </webServices>
    </system.web>
</configuration>
