推荐答案

几年前，我写了下面的示例并测试它与Mozilla和Opera一起使用。它将选择存储在一个cookie中，并可以从该cookie恢复选择。它生成并存储一个XPath表达式给选定范围的startContainer和endContainer以及偏移量的数字。

Some years ago I wrote the following sample and tested it to work with Mozilla and with Opera. It stores the selection in a cookie and can restore the selection from that cookie. It generates and stores an XPath expression to the startContainer and endContainer of the selected range and the numbers of the offset.
