我已经搜索并搜索了一个答案,所以希望我没有在任何地方重复这个。
我使用ASP .NET MVC5,KnockoutJS作为我的ORM。
出于某种原因,数据不被在DOM填充,当我尝试使用$根结合上下文(一旦进入“与”结合上下文)
引用回视图模型的结合与背景是在一个正常的mvc视图剃须刀页面中声明的,但是我在加载到主视图中的部分视图中使用$ root绑定上下文。
有没有人有这样的问题,或可以发现我的错误?我将在下面粘贴我的viewmodel和html代码。
视图模型
var ProfileViewModel = function() {
var self = this;
this.Member = ko.observable(); - With Binding to this
this.SocialNetworks = ko.observableArray();
this.Skills = ko.observableArray();
this.SkillsFilter = ko.observable(""); - Trying to access these from root
this.FilteredSkills = ko.observableArray();
this.References = ko.observableArray();
this.Has = function (has_what) {
if (has_what) {
if (has_what.length > 0) {
return true;
} else {
return false;
}
}
return false;
};
$.getJSON("/doitgrad/api/member/CameronPearce91", function (allData) {
self.Member(new DoItGrad.Objects.Member(allData, true));
self.FilteredSkills = ko.computed(function() {
return ko.utils.arrayFilter(self.Skills(), function (item) {
var filter = self.SkillsFilter(),
doesnthaveskill = (jQuery.inArray(item, self.Member().details.skills()) == -1),
containsfiltertext = (item.title().indexOf(filter) > -1);
if (filter != "") {
return (doesnthaveskill && containsfiltertext);
} else {
return doesnthaveskill;
}
});
});
})
$.getJSON("/doitgrad/api/skill/", function (allData) {
var mappedSkills = $.map(allData, function (item) { return new DoItGrad.Objects.Skill(item); });
self.Skills(mappedSkills);
});
}
var model = new ProfileViewModel();
ko.applyBindings(model);

如果有人需要了信息,感觉随意问。
您可以显示什么$根包含使用
内“同向”结合 –好,只是去尝试,似乎observableArray FilteredSkills不填充什么?但是,如果我在控制台中引用模型,则会填充数据..任何想法? –
