为什么ASP.NET MVC在从IE而不是firefox发布数据时会抱怨null参数？

Question

奇怪的事情发生在这里.

我有一些JS发布到ASP.NET MVC ActionMethod,它可以在除IE的任何版本之外的每个浏览器中查找.有问题的代码如下:

$.ajax({
        url: path,
        type: 'POST',
        data: { team: team_copy[team_copy.length - 1], queryDate: d.toUTCString(), newOutlets: newOutlets },
        success: function (MyResponseObject) {
            holder.append(MyResponseObject.content);
            //locate active section and click to show new content - its a mess, but it works
            //activeMenu.click();
            MessageSystem.showMessage("Target Data System", MyResponseObject.message, false);
            if (team_copy.length > 1) {
                team_copy.pop();
                $('#actualprogress').animate({ width: '+=' + TargetReports.progressratio + '%' }, 'slow');
                TargetReports.getTeamData(team_copy, d, newOutlets);
            }
            else {
                MessageSystem.showMessage("Complete", "All Data Fetched", false);
                $('#show-calendar-selection').fadeIn();
                TargetReports.buildTotalsTable("daysandcalls", "daysandcallstotal");
                TargetReports.buildTotalsTable("volumeanddistribution", "volumeanddistributiontotal");
                TargetReports.buildTotalsTable("outletactivation", "outletactivationtotal");
                TargetReports.buildTotalsTable("promotion", "promotiontotal");
                //$('#progress').fadeOut().remove();
                $('#results-options').fadeIn();
                $('#total-holder').fadeIn();
                activeMenu.click();

                //update link to download file
                var hidden = $('.hidden-information').first();
                var newOutlets = encodeURIComponent($('input[name="newoutlets"]', hidden).val());
                var queryDate = encodeURIComponent($('input[name="enddate"]', hidden).val());
                var anchor = $('#get-target-reports');
                var link = anchor.attr('href');

                link = "/manager/TargetResults.csv?endDate=" + queryDate + "&newOutlets=" + newOutlets;
                anchor.attr('href', link);
            }
        }
    });

Action Method签名如下所示:

 public ActionResult GenerateTargetData(int team, DateTime queryDate, bool forceRegen = false, bool newOutlets = false)

在IE .NET中运行时,会抱怨queryDate参数的空条目.使用IE中的调试工具我可以看到请求体看起来如下:

team=7&queryDate=Mon%2C+29+Nov+2010+23%3A15%3A39+UTC&newOutlets=false

在Firefox中,它有效:

team=7&queryDate=Mon%2C+29+Nov+2010+23%3A10%3A46+UTC&newOutlets=false

我真的不知道这里有什么.所有帮助赞赏!

您的问题似乎是因为ASP.net MVC模型绑定器将接受ISO8601格式的日期时间.

如果时间是UTC,则在没有空格的时间之后直接添加"Z".'Z'是零UTC偏移的区域指示符.因此,"09:30 UTC"表示为"09:30Z"或"0930Z"."14:45:15 UTC"将是"14:45:15Z"或"144515Z".

我已经检查过chrome 12.0.733.0 dev,Firefox 4,IE 9.如果你调用javascript toUTCString(),不同的浏览器返回不同的东西.Chrome和Firefox将返回"Wed,20 Apr 2011 20:31:11 GMT ",只有IE返回"Wed,2011年4月20日20:31:11 UTC "

d.toUTCString().replace('UTC','Z')对你有用.
