我希望按钮组充当here等单选按钮。
我想要的是:
如何使用我当前的代码实现这一目标?
我的HTML:
Filter By Title:
<div class="btn-group">
<button type="button" ng-repeat="title in titles" class="btn btn-default" ng-model="selected[title]" btn-checkbox>{{title}}</button>
</div>
<table class="table table-bordered table-striped">
<thead>
<tr>
<th>Title</th>
<th>Text</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="entry in entries | filter:byTitle">
<td>{{entry.title}}</td>
<td>{{entry.text}}</td>
</tr>
</tbody>
</table>
我的JS:
App.controller('MainCtrl', function($scope, $http) {
$http.get('output/entries.json')
.then(function(res){
$scope.entries = res.data;
});
$scope.selected = {};
$scope.titles = ["sometitle","someothertitle","anothertitle"];
function isChecked(obj){
var checked = [];
for(var key in obj){
if(obj[key])
checked.push(key);
}
return checked;
};
$scope.byTitle = function(entry){
var checked = isChecked($scope.selected);
return checked.indexOf(entry.title) > -1;
};
} );

这是否符合您的想法?

请注意,您的按钮需要有ng-class
和ng-click
。 ng-click
需要是一个函数调用,它设置范围变量而不是由于ng-repeat而设置的赋值,这会创建子范围。
<button
type="button"
ng-repeat="title in titles"
class="btn btn-default"
ng-model="selected[title]"
btn-checkbox
ng-class="{active: title == selectedTitle}"
ng-click="setSelectedTitle(title)">{{title}}</button>
然后你的函数选择一个变量:
$scope.setSelectedTitle = function (value) {
if ($scope.selectedTitle === value) {
$scope.selectedTitle = undefined;
} else {
$scope.selectedTitle = value;
}
};
我不确定你是否想让它切换。如果不是:
$scope.setSelectedTitle = function (value) {
$scope.selectedTitle = value;
};
