$scope.sortedType = 'firstName';
$scope.sortedReverse = false;
//Remove Rows and Update localStorage Key Values

$scope.retrievedData.splice(row, 1);
$scope.initData.splice(row, 1);
$window.localStorage.setItem('initData', JSON.stringify($scope.initData));

问题是我只能按索引确定第一项或第二项的范围,依此类推。如何将它们全部确定范围,然后用显示在HTML文件中*ngFor
?

var stringifiedNumbers = numbers.map(function(x) {
JSON.stringify(x);
})
console.log(stringifiedNumbers);
