错误:ngRepeat:复制中继器中的重复密钥(需要按$index跟踪)

$scope.addMotFault = function(idx) {
    if ($scope.problems.length > 1) {

        // Now more than one item, we need to 
        // inject the additional one under the clicked item

        // this index + 1
        problemPrototype.key = idx + 1;
        $scope.problems.splice(idx + 1, 0, angular.copy(problemPrototype));


    } else {

        // Only one item, so just push new problem
        // no need to "inject"

        problemPrototype.key = 0;
        $scope.problems.push(angular.copy(problemPrototype));
    }

};

html格式:

<div ng-repeat="problem in problems" style="border: 1px #ccc solid; margin:5px; padding: 5px">

我相信这会奏效的。
