Range:cloneRange() 方法

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since March 2017.

Range.cloneRange() 方法返回一个 Range 对象,其边界点与被克隆的 Range 相同。

返回的克隆是按值复制的,而非按引用复制,因此其中一个 Range 的更改不会影响另一个。

range.selectNode(document.getElementsByTagName("div").item(0));
