我试图创建一个简单的
twitter bootstrap button group,允许用户选择几个选项之一(思考单选按钮).我有一个这样的一个点,它影响到模型的变化,但是“活动”状态没有被正确设置,除非我再次点击它？
I’ve created a fiddle和基本标记如下
<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) {
$event.preventDefault();
};
}
};
});
解决方法
你不需要90％的引导js来获得这样的东西,所有你需要做的就是做一个按钮组,并附加一些ng点击它和ng类：
function myscope($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>
