[{count:1000,children:{count:12232}},{count:1000,children:{count:12232}}]用js给里面的count设置千分符

您可以使用Intl.NumberFormat对象来为数字添加千分符。下面是一个使用JavaScript将数字添加千分符的示例代码：

const data = [
  { count: 1000, children: { count: 12232 } },
  { count: 1000, children: { count: 12232 } }
];

const formatter = new Intl.NumberFormat();

const result = data.map(item => {
  const { count, children } = item;
  const formattedCount = formatter.format(count);
  const formattedChildrenCount = formatter.format(children.count);
  return { count: formattedCount, children: { count: formattedChildrenCount } };
});

console.log(result);

输出结果为：

[
  { count: "1,000", children: { count: "12,232" } },
  { count: "1,000", children: { count: "12,232" } }
]

这样，您就可以使用JavaScript为数组中的每个对象添加千分符了。
