如何计算json数据中所有得分的总和？
我的app.js看起来像这样，我已经迭代了json数据以获得总分并试图在视图上使用$ scope.sum变量
var app = angular.module('myApp', []);
app.controller('LeaderboardController', function($scope, $http) {
$http.get("gamify.json")
.success(function (response) {
$scope.names = response;
angular.forEach($scope.names, function(name, mainIndex) {
angular.forEach(name.awards,function(awards,maindemoIndex){
angular.forEach(awards.points,function(point,baseIndex){
$scope.sum+=point.score
});
});
});
}）; }）;
这是我到目前为止所尝试过的。
答案 0 :(得分：0)
您可以使用.map和.reduce的组合来循环并总计得分，然后分配到$scope个变量（尽管标准for循环可能更容易读取）：
$scope.totalScore = data.map(function(item) {
return item.awards.map(function(award) {
//Map out the score from each inner score array
return award.points.map(function(score) {
return score.score;
//Total those scores
}).reduce(function(p, c) {
return p + c;
});
//Total all inner arrays
}).reduce(function(p, c) {
return p + c;
});
//Total everything!
}).reduce(function(p, c) {
return p + c;
});
常规for循环：
var total = 0;
for (var i = 0; i < data.length; i++) {
for (var j = 0; j < data[i].awards.length; j++) {
for (var k = 0; k < data[i].awards[j].points.length; k++) {
total += data[i].awards[j].points[k].score
}
}
}
