for循环中的javaScript数组对象

Question

我有一个关于对象的 javaScript 数组的问题：

它看起来像下面：

$scope.todos = [
    {
        face : imagePath,
        what: 'Das',
        who: 'Sophia',
        when: '3:08PM',
        notes: " Description 1",
        linkForward: "#/tab/listView1"
    },
    {
        face : imagePath,
        what: 'Dis',
        who: 'Emma',
        when: '3:08PM',
        notes: " Description 1",
        linkForward: "#/tab/listView2"
    },
    {
        face : imagePath,
        what: 'Dos',
        who: 'Olivia',
        when: '3:08PM',
        notes: " Description 1",
        linkForward: "#/tab/listView3"
    }
];

我想在 for 循环中推送所有这些项目：

它应该看起来像：

for(var i = 0; i < 3; i++){
    $scope.todos[i].face = 'image Path'
    $scope.todos[i].what= 'image Path'
    $scope.todos[i].who= 'image Path'
    $scope.todos[i].when= 'image Path'
    $scope.todos[i].linkForward= 'image Path'

}

但它不起作用，我想动态创建这个数组。

您应该首先定义一个数组，如$scope.todos = [] & 更好的方法是像下面这样设置数组。

$scope.todos = []
for(var i = 0; i < 3; i++){
    $scope.todos.push({
       face: 'image Path', 
       what : 'image Path', 
       who: 'image Path', 
       when: 'image Path', 
       linkForward: 'image Path'
    });
};
