我正在使用kendo UI和角栅格应用程序。我的网格从JSON数据填充（单独的文件），我使用的角度服务：如何绑定外键kendo ui dropdownlist（with angular）
我的JSON数据：
[
{ "Id": 1, "AccountNo": "10236", "PostingDate": "20.01.2015", "MaturityDate": "24.01.2015", "Description": "description1", "DocumentTypeId": 1 },
{ "Id": 2, "AccountNo": "10648", "PostingDate": "26.01.2015", "MaturityDate": "28.01.2015", "Description": "description2", "DocumentTypeId": 2 },
{ "Id": 3, "AccountNo": "10700", "PostingDate": "22.01.2015", "MaturityDate": "25.01.2015", "Description": "description3", "DocumentTypeId": 3 },
{ "Id": 4, "AccountNo": "10810", "PostingDate": "24.01.2015", "MaturityDate": "27.01.2015", "Description": "description4", "DocumentTypeId": 2 },
{ "Id": 5, "AccountNo": "10101", "PostingDate": "29.01.2015", "MaturityDate": "30.01.2015", "Description": "description5", "DocumentTypeId": 4 },
{ "Id": 6, "AccountNo": "10364", "PostingDate": "25.01.2015", "MaturityDate": "31.01.2015", "Description": "description6", "DocumentTypeId": 6 }
]
我的角度服务：
angular.module("app").factory('myService', function ($http) {
return {
getAll: function (onSuccess, onError) {
return $http.get('/Scripts/app/data/json/master/masterGridData.js').success(function (data, status, headers, config) {
onSuccess(data);
}).error(function (data, status, headers, config) {
onError(data);
});
},
getDocumentTypes: function (onSuccess, onError) {
return $http.get('/Scripts/app/data/json/documentType.js').success(function (data, status, headers, config) {
onSuccess(data);
}).error(function (data, status, headers, config) {
onError(data);
});
}
}
});
这是我的控制器：
var app = angular.module("app", ["kendo.directives"]).controller("myController", function ($scope, myService) {
$scope.tabStrip = null;
$scope.$watch('tabStrip', function() {
$scope.tabStrip.select(0);
});
$scope.masterDataSource = new kendo.data.DataSource({
transport: {
read: function (options) {
url = "/Scripts/app/data/json/master/masterGridData.js",
myService.getAll(function (data) {
options.success(data);
}).error(function (data) {
options.error(data);
})
}
},
schema: {
model: {
id: "Id",
fields: {
Id: { type: "number" },
AccountNo: { type: "string" },
PostingDate: { type: "string" },
MaturityDate: { type: "string" },
Description: { type: "string" },
DocumentTypeId: { type: "number" }
}
}
},
pageSize: 16
});
$scope.gridMaster = {
columns: [
{ field: "Id", hidden: true },
{ field: "AccountNo", title: "Account No", width: "77px", template: '<div style="text-align:left;">#= kendo.toString(AccountNo) #</div>' },
{ field: "PostingDate", title: "Posting Date", width: "70px" },
{ field: "MaturityDate", title: "Maturity Date" width: "70px" },
{ field: "Description", title: "Description", width: "170px" },
{ field: "DocumentTypeId", hidden: true }
],
dataSource: $scope.masterDataSource,
selectable: true,
filterable: true,
scrollable: true,
pageable: {
pageSize: 16,
//refresh: true,
pageSizes: ["50", "100", "200", "All"]
},
toolbar: [{
name: "create"
}],
change: function() {
var dataItem = this.dataItem(this.select());
$scope.isRowSelected = true;
$scope.id = dataItem.Id;
$scope.accountNumber = dataItem.AccountNo;
$scope.postingDate = dataItem.PostingDate;
$scope.description = dataItem.Description;
$scope.maturityDate = dataItem.MaturityDate;
$scope.documentTypeId = dataItem.DocumentTypeId;
}
};
$scope.documentType = {
dataSource: {
transport: {
read: function (options) {
url = "/Scripts/app/data/json/documentType.js",
myService.getDocumentTypes(function (data) {
options.success(data);
}).error(function (data) {
options.error(data);
});
}
},
schema: {
model: {
id: "Id",
fields: {
Id: { type: "number" },
Name: { type: "string" }
}
}
}
},
dataTextField: "Name",
dataValueField: "Id"
}
});
这是我的JSON，其中包含documentType的数据：
[
{ "Id": 1, "Name": "Document 1" },
{ "Id": 2, "Name": "Document 2" },
{ "Id": 3, "Name": "Document 3" },
{ "Id": 4, "Name": "Document 4" },
{ "Id": 5, "Name": "Document 5" },
{ "Id": 6, "Name": "Document 6" }
]
这是我的HTML：
<html>
<head>
<!-- css and javaScript files -->
</head>
<body ng-app="app" ng-controller="myController">
<div class="divH3Style">
<h3 class="h3LabelForm">Grid Master</h3>

在HTML我有下拉列表包含数据documentType和我的下拉列表填充了JSON数据。但是，问题在于约束力。当我选择一些网格行下拉列表时，总是显示第一项。我的网格数据源包含外键值（documentTypeId），并且此值应与来自documentType JSON文件的Id值匹配，即$ scope.documentType属性的dataValueFiled值。如何绑定这个下拉列表？请帮助..
