在angular $ scope中更新JS Array

Question

我正在尝试更新$ scope内的数组。例如

$scope.data = [{detail:{name: "...", cred:"...."}, date:"current date"},...];
$scope.update = function(){
  $scope.data[0].date = "new date";
}

但价值没有更新。我做错了吗？

Answer 1

$scope.data = [{detail:{name: "...", cred:"...."}, date:"current date"},...];
$scope.update = function(){
  $scope.data[0].date = "new date";
}

嗨，有时上面的角度视图可能无法直接反映更改，因此要实现此目的，请使用$ watch或$ watchCollection;

$scope.$watchCollection('data', function(value){
  $scope.data = value;
});
