定义和用法

ng-repeat 指令重复一组 HTML,指定次数。

这组 HTML 将在集合中的每个项目上重复一次。

集合必须是数组或对象。

注意:每次重复都拥有自己的作用域,其中包含当前项目。

如果您有一个对象集合,则 ng-repeat 指令非常适合创建 HTML 表格,为每个对象显示一行表格,为每个对象属性显示一个表格数据。请参见下面的示例。


语法

<元素 ng-repeat="表达式"></元素>

所有 HTML 元素都支持。


参数值

描述
表达式 指定如何循环集合的表达式。

合法表达式示例

x in records

(key, value) in myObj

x in records track by $id(x)
