我错过了什么?请帮忙。这是我的代码
var data= {
"CountyOfPractice":"Bronx",
"Territory":"TERR0102",
"Specialty":"OralSurgery",
"Fulltime":true,
"Occurence":false,
"Discounts":"waiver_of_consent,one_time_payment",
"Payment":null,
"Rate":{"Claims made year 1":7668,
"Claims made year 2":14667,
"Claims made year 3":19171,
"Claims made year 4":21181,
"Claims made year 5":22982,
"Mature Claims Made: ":24253}
};
//Create model
var viewModel = ko.mapping.fromJS(data);
//bind
ko.applyBindings(viewModel);
这是HTML
<input type="text" data-bind="value: CountyOfPractice" />
并且没有任何反应,输入框是空的。请指教
