从范围的角度JS NG-重复一个单选按钮列表用默认选中 [英] angular js ng-repeat a radio button list from scope with a default checked

问题描述

app.controller('radiusController', function($scope){
    $scope.radii = [
        {id:.25, checked:"false", name:"1/4 Mile"},
        {id:.5, checked:"false", name:"1/2 Mile"},
        {id:1, checked:"false", name:"1 Mile"},
        {id:2, checked:"true", name:"2 Mile"},
        {id:3, checked:"false", name:"3 Mile"},
        {id:4, checked:"false", name:"4 Mile"},
        {id:5, checked:"false", name:"5 Mile"}
    ];
    $scope.handleRadioClick = function(radius){
        window.radiochecked = radius.id;
    };
});

<li ng-repeat="radius in radii" id="selectradius-{{radius.id}}">

              <div class="radio">
                <label>

                  <input type="radio" name="radius"
                       ng-model="radius.checked"
                       ng-change="handleRadioClick(radius)">

                  {{radius.name}}

                </label>
              </div>

          </li>

我如何设置默认的单选按钮，可以根据半径范围内的检查值检查？在这种情况下，2英里应该是默认进行检查。

How do I set the default radio button to be checked based on the checked value of scope radii? In this case the "2 Mile" should be checked by default.

推荐答案

简单。 Eventhough角文档不提NG-检查，它是可用的。

Simple. Eventhough the angular docs do not mention ng-checked, it is available.

<input type="radio" name="radius"
                       ng-change="handleRadioClick(radius)"
                       ng-checked="radius.checked">
