在此fiddle内view appointmnets标签中，有一个可用的医院下拉菜单，其中包含3个字段A，B，c。
现在我想从我从JSON获得的值中创建这个下拉列表。
这是我的JSON数据
{
"doctors": [
{
"id": 1,
"schedules": [
{
"id": 1,
"totime": "13:19",
"dayId": 1,
"location": "Somajiguda",
"fromtime": "12:19",
"hospitalId": 5,
"day": "Monday",
"hospital": "Yashoda"
}
],
"username": "doctor",
"degree": "MBBS,MD",
"email": "a@b.com",
"imagePath": "imagePathValue",
"department": "Bio-Chemistry",
"name": "doctor",
"userid": 4,
"gender": "Male",
"mobile": "1234567890"
}
]
}
在上面的JSON中，医院"hospital": "Yashoda"有一个值，所以我只想要＆＃34; Yas hoda＆＃34;在上面的JSON中，还有totime和fromtime字段。我能够得到那些字段，但我没有在下拉列表中获得医院名称。任何人都可以在这里投入一些光。
这是我的更新fiddle，以下是js代码
var DocSchedule = function(id, day, fromtime, totime, hospital, hospitalId) {
this.id = ko.observable(id);
this.day = ko.observable(day);

this.hospitalId = ko.observable(hospitalId);

我刚刚更改了你的html代码，现在正在运行
<select class="span8" name="hospital"
data-bind="options: $root.hospitalOptions,value: docp.hospital,optionsCaption: 'Select Hospital'"
data-required="true" data-trigger="change">
