用ng-repeat迭代数组值

Question

给定以下对象:

{
    key1: ["val1","val2","val3","val4"],
    key2: ["val2","val5","val22","val4","val8","val1"],
    key3: ["val1"],
    key4: ["val11","val12"]
}

是否可以使用ng repeat一次迭代所有值？

我的动机是:1。我在<代码>中使用ng-repeat

<tr>
    <td>key1.val1</td>
</tr>
<tr>
    <td>key1.val2</td>
</tr>
<tr>
    <td>key1.val3</td>
</tr>
<tr>
    <td>key1.val4</td>
</tr>
<tr>
    <td>key2.val2</td>
</tr>
<tr>
    <td>key2.val5</td>
</tr>
... and so on ...

有什么想法吗？

谢谢！

Answer 1

$scope.allValues = [];
angular.forEach(object, function(array) {
    array.forEach(function(value) {
        $scope.allValues.push(value);
    });
});

然后只需在< code>allValues上使用ng-repeat。

由于您的键是对象的属性，我将在第一步将其转换为数组：

$scope.keys = [];
for (var property in object) {
    if (object.hasOwnProperty(property)) {
         $scope.keys.push(object.property);
    }
}

然后您可以使用嵌套的ng重复指令显示所有值：

<div ng-repeat="key in keys">
   <div ng-repeat="val in key[$index]">
      {{val}}

编辑：还有一种方法可以直接迭代对象属性

<div ng-repeat="(key, value) in myObj"> ... </div>
