控制器：

app.controller('MainCtrl', function($scope) {
$scope.inquiry = {

]
};
$scope.cancelInquiry = function () {
$scope.inquiryFormShow = false;
}
$scope.add_inquiry_question = function (inquiry_questions) {
inquiry_questions.push({name: "", type: "text", form: "multiple", inquiry_answers: []});
}
$scope.remove_inquiry_question = function (inquiry_questions,index) {
inquiry_questions.splice(index, 1);
};
$scope.add_inquiry_answer = function (inquiry_answers) {
inquiry_answers.push({name: ""});

};
});
基本上在ng-repeat ngmodel中，这些单选按钮似乎对任何更改都没有响应。正如您在创建新问题并在无线电中选择值后可以在plunker中看到的那样，ng-if不会尊重此值。如果我从json预填充查询对象，则所有单选按钮都是非选择的，如果它们在json中有值。用于文本输入的Ng模型效果很好。
你能帮我吗？
答案 0 :(得分：0)
根据我的理解，你应该使用带有角度表达式而非纯文本的ng-value，这意味着使用范围变量，而不是ng-value="text"，而不是使用$scope.textValue = 'text';
。
ng-value="textValue"
并将ng值绑定到该表达式
ng-if="inquiry_question.type==='images'"
当然所有其他ng值（图像，单个，多个选择）
也是如此关于ng-ifs，它只是
ng-if="inquiry_question.type=='images'"
而不是
org.eclipse.ui.main.toolbar这是一个有效的plunker。
