将参数从WebMethod传递给Jquery

Question

我有以下WebMethod: -

        [WebMethod(EnableSession = true)]
    public static void OpenReport(string reportName)
    {
        Report report = reportsBll.GetReports().FirstOrDefault(x => reportQuestion != null && x.Id == reportQuestion.ReportId);

        if (report != null) reportUrl = report.Url;
    }

现在我希望传递report.Url到这个Jquery方法: -

    $('.ReportButton').click(function () {
    var args = { reportName : '' };

    $.ajax({
        type: "POST",
        url: "ReportsByQuestionsDetails.aspx/OpenReport",
        data: JSON.stringify(args),
        contentType: "application/json;charset=utf-8;",
        success: function (data) {
            alert('success');
            document.location.href = reportUrl;
        },
        error: function () {
        }
    });
});

如何将reportUrl从WebMethod传递给Jquery？

谢谢你的帮助和时间

您需要返回的string在C#方法:

[WebMethod(EnableSession = true)]
public static string OpenReport(string reportName)
{
    string reportUrl = string.Empty;
    Report report = reportsBll.GetReports().FirstOrDefault(x => reportQuestion != null && x.Id == reportQuestion.ReportId);

    if (report != null) reportUrl = report.Url;

    return reportUrl;
}

然后在你的ajax返回Url中你可以做(​​你可能希望在报告为null时回退):

success: function (data) {
    location.href = data;
},
