我是angularjs的新手，所以我不知道如何将任何值推送到特定位置的数组。例如 ：
$scope.atparticular.push =
[
{questionText: 'queston1',questionId: '1',answerlst:[{answerText:'answer1',answerId: 'a1'},{answerText: 'answer2',answerId: 'a2'},{answerText: 'answer3',answerId: 'a3'}]},
{questionText: 'row2queston1',questionId: 'rq1',answerlst:[{answerText:'row2answer1',answerId: 'row2a1'},{answerText: 'row2answer2',answerId: 'row2a2'},{answerText: 'row2answer3',answerId: 'row2a3'}]}
];
如果这是我的包含列表的对象，并且如果我想在answerlst后面追加一个包含空值的位置，例如：
$scope.atparticular.push =
[
{questionText: 'queston1',questionId: '1',answerlst:[{answerText:'answer1',answerId: 'a1'},{answerText: 'answer2',answerId: 'a2'},{answerText: 'answer3',answerId: 'a3'},{answerText: '',answerId: ''}]},
{questionText: 'row2queston1',questionId: 'rq1',answerlst:[{answerText:'row2answer1',answerId: 'row2a1'},{answerText: 'row2answer2',answerId: 'row2a2'},{answerText: 'row2answer3',answerId: 'row2a3'},{answerText: '',answerId: ''}]}
];
请给一些建议。提前致谢。
如果我理解正确，您想在arrayanswerlst的第一个元素的数组末尾添加一个对象$scope.atparticular.push。
所以你要：
$scope.atparticular.push[0].answerlst.push({answerText: '',answerId: ''});
请注意，这与angularJS本身无关。这只是普通的JavaScript。
