Question

我想选择多个无线电选项。新到angularjs。

产生问题的步骤：

从第一个选择菜单中选择任意国家/地区 - ＆gt;选择原因A
从第二个选择菜单中选择任意国家/地区 - ＆gt;选择理由C

此处上述原因A选项消失，仅选择了原因C. 我想举出不同国家部分的两个不同原因。

var app = angular.module('myApp', []);
app.controller('myController', function ($scope) {
$scope.showReasonA = function showReasonA(checkNoTin) {
    console.log("print the notin value from data",this.item.noTin);
    if (!this.item.country) return false;
    var selectedCountry = this.item.country.country.toLowerCase();
    var fourCountries = ["cayman islands", "albania"]
    var isIt = fourCountries.indexOf(selectedCountry) >= 0;
    console.log("print match country val",isIt);
    console.log("get checknotin value before assign",checkNoTin);
    if (checkNoTin) this.item.noTin = true;
    console.log("final checknotin val",checkNoTin);
    return isIt;
  }
});

和视图

Answer 1

要将某些输入设为隐藏，您可以使用

<p ng-show="condition">I'm shown</p>

并且此条件值应在控制器范围内初始化

$scope.condition=true/false

隐藏节目输入，您可以使用ng-if。最好使用ng-if进行动态输入。查看详细信息here

现在针对您的情况，您可以在条件中使用item.reason来显示和隐藏您的输入。

<input type="radio" name="reason" ng-model="item.other" ng-value="C" required="required" ng-if="item.reason='object:836'" />

Answer 2

终于得到了解决方案

我刚刚添加了带索引的单选按钮名称然后它工作，这将为每组按钮提供不同的名称。

名= '原因_ {{$索引}}'
