我调用了REST服务,它给了我一个包含地图的对象。 java中的地图看起来像地图
以下是我的js
$scope.marks = {};
//get data from rest
StudentService.query().$promise.then(function(data)
{
$scope.students = data;
for(var i=0;i<$scope.students.length;i++){
var obj = $scope.students[i];
//marks (key=studentName, value=mark in decimal)
$scope.marks[obj["studentName"]]=0.0;
}
以下是我的HTML
<div class="row" ng-repeat="(key,value) in marks">
<input type="text" class="form-control" ng-model="key" disabled>
{{marks[key]}} <!-- Here it is not updating value from above model-->
<input type="number" class="form-control" ng-model="value">
</div>
当我在textfield中更新值时,它不是在textfiled下面显示的更新值,即{{marks[key]}}
未显示更新的值。如果错误请纠正我。谢谢:))

您传递给ng-model
的只是一个字符串,它是不可变的。您需要像这样定义ng-model
:
<input type="number" class="form-control" ng-model="marks[key]">
angular.module('app', [])
.controller('Ctrl', function($scope) {
$scope.marks = {
mark1: 1,
mark2: 2,
mark3: 3
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="app" ng-controller="Ctrl">
<div class="row" ng-repeat="(key,value) in marks">
<input type="text" class="form-control" ng-model="key" disabled>{{marks[key]}}
<!-- Here it is not updating value from above model-->
<input type="number" class="form-control" ng-model="marks[key]">
</div>
</div>
