创建和初始化数组二维在javascript

Question

我试图创建和初始化AngularJS应用程序内的JavaScript一个二维数组如下：

$scope.invalidVote = []; 
for (var i = 0; i < $scope.arry1.length; i += 1) { 
    $scope.answersCount[i] = $scope.arry1[i].arry2.length; 

    for(var j = 0; j < $scope.arry1[i].arry2.length; j += 1) { 
     $scope.invalidVote[i][j] = false; 
    } 
} 

但它不工作，什么是应该做的正确方法那？

Answer 1

试试这个：

$scope.invalidVote = []; 
for (var i = 0; i < $scope.arry1.length; i++) { 
    $scope.answersCount[i] = $scope.arry1[i].arry2.length; 
    $scope.invalidVote[i] = []; 

    for(var j = 0; j < $scope.arry1[i].arry2.length; j++) { 
     $scope.invalidVote[i][j] = false; 
    } 
} 

Answer 2

我假设$scope.arry1[i]是包含其他数组和已经与值填充数组。 所以，你的代码应该是这样的：

$scope.invalidVote = $scope.arry1; 
for (var i = 0; i < $scope.arry1.length; i += 1) 
    { 
    $scope.answersCount[i] = $scope.arry1[i].length; 
    for(var j = 0; j < $scope.arry1[i].length; j += 1) 
     { 
     $scope.invalidVote[i][j] = false; 
     } 
    } 

'$ scope.invalidVote = $ scope.arry1;'像这样声明“invalidVote”确保它包含相同数量的索引。
