asp.net-mvc – 为什么ASP.NET MVC在从IE而不是firefox发布数据

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！
