$window.focus() 不适用于 iOS Safari 中的现有选项卡

Question

When I open a new window with var win = window.open("", "name") and then focus the window using win.focus() this works for the first time in iOS Safari.

But when the existing window is referenced again by name using window.open I can't focus again in iOS Safari. In Chrome this works fine.

Is there any way how I can focus on an already existing tab just knowing the name?

I created a fiddle for testing: https://jsfiddle.net/szqnu38f/

Answer 1

This seems to be a bug within iOS Safari.

Generally, it is not possible to set the focus again on an existing named tab. This is also the case when a link with target set to a name is clicked again after the tab was opened --> see https://jsfiddle.net/g3bk1v5a/4/

Therefore, I opened a bug report at Apple.

Until the bug is fixed by Apple, you may use the following workaround:

// replace win.focus() by:
win.close();
win = win.open("", "name");
