如何使Twitter Bootstrap按钮组与AngularJS一起使用？

Question

我正在尝试创建一个简单的twitter bootstrap按钮组,允许用户选择几个选项之一(想想单选按钮).我已经达到了影响模型变化的程度,但"活动"状态没有正确设置为onclick ...除非我再次点击它？我创造了一个小提琴,基本标记如下......

<div range="justified"
    model="myModel"
    options="rangeOptions"></div>
<hr/>
<div range="vertical"
    model="myModel"
    options="rangeOptions"></div>
<hr/>

<pre>myModel:{{myModel}}</pre>

<script type="text/ng-template" id="range.tpl.html">
    <div class="btn-group btn-group-{{type}}" data-toggle="buttons">
        <span class="btn btn-lg btn-primary"
            ng-repeat="option in options"
            ng-class="{active:option.id==model.range_id}" <!-- not working?? -->
            ng-click="activate(option.id)">{{option.label}}</span>
    </div>
</script>

function Main($scope) {
    $scope.rangeOptions = [
        {id:1,label:"Agree"},
        {id:2,label:"Neutral"},
        {id:3,label:"Disagree"}
    ];
    $scope.myModel = {range_id: 2};
}
angular
    .module('range', [])
    .directive('range', function () {
        return {
            replace: true,
            scope: { type:'@range', model:'=', options:'=' },
            templateUrl:'range.tpl.html',
            controller: function ($scope,$element,$attrs) {
                $scope.activate = function (option) {
                    $event.preventDefault();
                };
            }
        };
    });

你不需要90%的bootstrap js来实现这样的工作你需要做的就是创建一个按钮组并附加一些ng-click和ng-class:

function myscope($scope) {
  $scope.button = 'red';
}

<div class="btn-group">
    <a href="javascript:void(0)" ng-click="button = 'red'" ng-class="{ 'active' : button == 'red' }" class="btn">red</a>
    <a href="javascript:void(0)" ng-click="button = 'blue'" ng-class="{ 'active' : button == 'blue' }" class="btn">blue</a>
    <a href="javascript:void(0)" ng-click="button = 'green'" ng-class="{ 'active' : button == 'green' }" class="btn">green</a>
</div>

这里有一些关于使您的按钮组作为单选按钮工作的其他信息.

使用该信息,我分叉你的小提琴,这似乎是有效的.

更改只是将span元素切换为标签/输入.

<div class="btn-group btn-group-{{type}}" data-toggle="buttons">
    <label class="btn btn-lg btn-primary"
        ng-repeat="option in options"
        ng-class="{active:option.id==model.range_id}"
    ng-click="activate(option.id)"><input type="radio"></input>{{option.label}}</label>
</div>
