Question

我的单选按钮有问题。我从JSON获取所有值，如标签，组件等，并在视图上呈现它。

示例：我从JSON获得了组件单选按钮的两个值，我在视图中呈现它，但问题是当我选择第一个单选按钮时，其他无线电值未被选中。 注意：这两个都在不同的div。

  {
    "autoselect": [
      "nihil est velit"
    ], 
    "component": "radio", 
    "description": "distinctio accusamus cum quod veniam voluptatibus dolor", 
    "editable": false, 
    "label": "qui excepturi laborum", 
    "options": [
      "nihil est velit", 
      "ad aliquid id", 
      "irure", 
      "veniam voluptas", 
      "velit ea consectetur"
    ], 
    "required": true
  }, 
  {
    "autoselect": [
      "qui soluta"
    ], 
    "component": "radio", 
    "description": "est rerum dolor quisquam", 
    "editable": false, 
    "label": "deserunt quia", 
    "options": [
      "qui soluta", 
      "aperiam ut", 
      "et nostrud"
    ], 
    "required": true
  }, 
  {
    "autoselect": [
      "occaecati impedit proident"
    ], 
    "component": "radio", 
    "description": "id cumque totam sapiente reprehenderit", 
    "editable": false, 
    "label": "sit ut", 
    "options": [
      "corrupti", 
      "quidem", 
      "occaecati impedit proident"
    ], 
    "required": true
  }

    </form>

JS代码

var app = angular.module('myApp', []);

app.controller('MainCtrl', function($scope, $http) {
  $scope.getForm = function() {
    var formdata = $http({
        method: 'GET',
        url: 'data.json'
      })
      .then(function(response) {
        $scope.renderTags = response.data.data;
      }, function(reason) {
      });
  };

  $scope.clicked = function(option, tag) {
    var index = tag.autoselect.indexOf(option);
    if (index > -1) {
      tag.autoselect.splice(index, 1);
    } else {
      tag.autoselect.push(option);

    }
  }
});

你可以帮我解决这个问题吗？ Link to Plunkr

尝试选中其中一个复选框，其他值将关闭。 提前致谢

Answer 1

name属性用于对单选按钮进行分组。将name属性设置为{{tag.label}}，以便将一个标签下的所有单选按钮分组

同时使用带有ng-checked表达式的ng-checked="tag.autoselect[0] === option"来检查默认值

更改HTML <span>

这

<span ng-if="tag.autoselect!==null">
  <span ng-if="tag.autoselect[0] === option">
      <input type="radio" checked ng-value="option" name="$index" ng-click="clicked(option,tag)">{{option}}
   </span>
   <span ng-if="tag.autoselect[0] !== option">
      <input name="$index" type="radio" ng-value="option">{{option}}
   </span>
</span>

要

<span ng-if="tag.autoselect!==null">
  <span>
    <input type="radio" ng-checked="tag.autoselect[0] === option" name="{{tag.label}}" ng-click="clicked(option,tag)" />{{option}}
  </span>
</span>
