Window:fence 属性

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

实验性: 这是一项实验性技术
在将其用于生产之前,请仔细检查浏览器兼容性表格

Window 接口的只读属性 fence 为当前文档上下文返回一个 Fence 对象实例。

Fence 对象仅对嵌入在 <fencedframe>(通过 FencedFrameConfig 加载)或 <iframe>(通过不透明 URN 加载)中的文档可用。

备注: 参见 <fencedframe> 的工作原理了解有关 FencedFrameConfig 和不透明 URN 的一些描述。

一个 Fence 对象实例,如果文档上下文无法访问 Fence 对象,则为 null

示例

js
window.fence.reportEvent({
  eventType: "click",
  eventData: JSON.stringify({ clickX: "123", clickY: "456" }),
  destination: ["buyer", "seller"],
});
