我需要选择的国家名进入键名country
,但$scope.options
将不被认可。我无法选择国家,更不用说将正确的国家转变为关键价值。所以有人知道我做错了什么,以及在这种情况下可能的解决方案。NG选项需要为对象值传递给数组
任何一个知道如何才能解决这个问题?
\t $scope.addComment = function() {
\t \t $scope.comments.push($scope.dataObject);
\t \t $scope.options = [{
\t \t \t id: 1,
\t \t \t country: "China"
\t \t \t },
\t \t \t {
\t \t \t id: 2,
\t \t \t country: "France"
\t \t \t },
\t \t \t {
\t \t \t id: 3,
\t \t \t country: "Germany"
\t \t \t },
\t \t \t {
\t \t \t id: 4,
\t \t \t country: "Japan"
\t \t \t },
\t \t \t {
\t \t \t id: 5,
\t \t \t country: "Hongary"
\t \t \t },
\t \t \t {
\t \t \t id: 6,
\t \t \t country: "Hong Kong"
\t \t \t },
\t \t \t {
\t \t \t id: 7,
\t \t \t countrybv : "Italy"
\t \t \t }]
\t \t $scope.dataObject = {
\t \t \t name: "",
\t \t \t country: $scope.options[0],
\t \t \t comment: ""
\t \t };
\t };
<body>
<td><select class="comment-form comment" ng-model="selected" ng-options="option as option.country for option in options track by option.id">
<option value="">Select a country</option>
</select></td>
</body>
问题是$ scope.options不会被识别.... –
“track by x.Id”应该是“track by x.id” – jbrown
我知道,已经阅读过文档,但它无法链接到ID。这是这样做的主要问题....也许我忽视了JavaScript的部分东西... –
