使用angularJS框架的話都需要引入angular.min.js文件,這個想必各位大佬都懂得,我就不多說了。
這裏主要說說如何判斷複選框是否選中,以及向集合中添加和移除id。
1、如果判斷複選框被選中呢
一般我們在複選框中都是這樣寫:
<td><input type="checkbox" ng-click="updateSelect(entity.id)"></td>
首先在複選框的ng-click中的updateSelect方法里加入$event,這個$event代表的就是複選框控件本身。將複選框傳給了updateSelect方法。這樣我們在updateSelect中就可以這樣做了:
$scope.selectIds=[];//用戶勾選的id集合
//用戶勾選複選框
$scope.updateSelect=function($event, id){
if($event.target.checked){
}else{
}
}
上面$event.target就是找到複選框對象,然後調用它的checked方法判斷複選框有沒有沒勾選,值爲true代表被勾選,值爲false代表取消勾選。
2、怎樣向selectIds集合中添加id值呢
調用push方法,如下:
$scope.selectIds.push(id);
3、怎樣從selectIds集合中移除id呢
比如我們要刪除一條數據,突然不想刪了,取消了複選框的勾選,那怎麼從selectIds中移除該條複選框的id值呢?
首先我們要在集合中找到id在集合中對於的位置
var index = $scope.selectIds.indexOf(id);
然後調用splice方法,如下:
$scope.selectIds.splice(index,1);//參數一:移除的位置,參數二:移除的元素個數
完整代碼如下,僅供參考,
