The name problem of multiple Windows using window.open of in js

When using window.open() to open multiple child Windows, after ie7, different names are used to open multiple different Windows. If the name is the same, only the first child window can be opened. If the child window and the parent window have data exchange or method calls to each other, if the name is the same, there will be many unpredictable errors, so many problems should be considered to be caused by this reason.
