我需要有两个下拉列表,每个列表最初包含1到9个整数。我想我可以使用以下内容来做到这一点:
<--html area-->
<select ng-repeat="num in MaxCupcakes">
<option ng-model="num" />
</select>
<select ng-repeat="num in MyCupcakes">
<option ng-model="num" />
</select>
<--script area -->
var app = angular.module("app", []);
app.controller('Ctrl', function() {
$scope.MaxCupcakes = [1,2,3,4,5,6,7,8,9];
$scope.MyCupcakes = [1,2,3,4,5,6,7,8,9];
});
一旦我将此设置正确,我想在MaxCupcakes中选择限制MyCupcakes中的数字。例如,如果我将最大杯形蛋糕设置为5,那么我只能在mycupcakes中选择1-5。

更好的方法是在第二个选择上使用过滤器。
<div ng-app ng-controller="Ctrl">
<select ng-model="max">
<option ng-repeat="num in MaxCupcakes" ng-click="changeMax(num)">
{{num}}
</option>
</select>
<select ng-model="foo>
<option ng-repeat="num in MyCupcakes | limitTo:max">
{{num}}
</li>
</select>
</div>
此外,您的阵列不应该有{}。这是ctrl应该是什么样子。
function Ctrl($scope) {
$scope.MaxCupcakes = [1,2,3,4,5,6,7,8,9];
$scope.MyCupcakes = [1,2,3,4,5,6,7,8,9];
$scope.max = 9;
};
