Javascript Visual Studio未自动完成JS函数

用于处理此函数的Autocomplete（当其参数较少时）：

并且仍然可以使用此功能（因此我知道已启用自动完成）：

在

var p=new player（…）

和

p.Fir….

上自动完成都不起作用

自动完成功能的大小有限制吗

谢谢

function player(firstName, lastName, hometownCity, hometownState, highSchoolName, otherAccountName, redshirted, transferred, hometownZip, hometownCountry, bioLink, collegeYear, HighSchoolGradYear, Position, Number, HeightFeet, HeightInches, Weight, Gender, PlayerId) {
this.FirstName = ko.observable(firstName);
this.LastName =  ko.observable(lastName);
this.HometownCity =  ko.observable(hometownCity);
this.HometownState =  ko.observable(hometownState);
this.Name_HighSchool =  ko.observable(highSchoolName);
this.Name_OtherAccount =  ko.observable(otherAccountName);
this.Redshirted =  ko.observable(redshirted);
this.Transferred =  ko.observable(transferred);
this.HometownZip =  ko.observable(hometownZip);
this.HometownCountry =  ko.observable(hometownCountry);
this.BioLink =  ko.observable(bioLink);
this.CollegeYear =  ko.observable(collegeYear);
this.HighSchoolGradYear =  ko.observable(HighSchoolGradYear);
this.Position =  ko.observable(Position);
this.Number =  ko.observable(Number);
this.HeightFeet =  ko.observable(HeightFeet);
this.HeightInches =  ko.observable(HeightInches);
this.Weight =  ko.observable(Weight);
this.Gender = ko.observable(Gender);
this.PlayerId = PlayerId;
}

function stuff(thing) {
this.thing = thing;
}
