只是一个小练习：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<script src="js/angular.min.js"></script>
<script>
var app = angular.module('myApp', []); // 定义了一个叫 myApp 的模块
// 定义控制器
app.controller('myController', function($scope) {$scope.list = [100, 192, 203, 434]; // 定义数组
$scope.selectIds=[];// 选中的 ID 集合
$scope.getsum=function($event,x){
$scope.sum=0;
if($event.target.checked){$scope.selectIds.push(x);
}else{var idx = $scope.selectIds.indexOf(x);
$scope.selectIds.splice(idx, 1);// 删除
}
for (var i of $scope.selectIds) {$scope.sum+=i;}
};
});
</script>
</head>
<body ng-app="myApp" ng-controller="myController">
<table>
<tr ng-repeat="x in list">
<td>{{x}}<input type="checkbox" ng-click="getsum($event,x)"></td>
</tr>
</table>
集合:{{selectIds}}
求和:{{sum}}
</body>
</html>前端真难。。
