Xul 的 window.blur() 不起作用？还有其他选择吗？
我正在尝试使用 window.blur() 打开一个没有焦点的窗口它（或者聚焦和散焦非常快，所以看起来它没有聚焦）。
但貌似不行，有其他办法吗？
我的尝试：
blurTest.xul:
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
<window width="400" height="300"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<script>
<![CDATA[
function onkeypress(event) {
// for this sample don't matter which key is pressed
open('second.xul','SecondWindow','chrome, width=400, height=300');
}
addEventListener("keypress", onkeypress, false);
]]>
</script>
<label value="MAIN WINDOW"/>
</window>
secondary.xul:
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
<window width="400" height="300"
onload="blur();"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<label value="SECOND" />
</window>
Obs. 我们可以考虑使用 setTimeout(window.focus, 1) 在打开后将焦点回调回我的窗口第二个窗口。但我需要第二个窗口来处理焦点。完美的情况是，如果第二个窗口永远无法获得焦点，只需打开/恢复窗口而不获得焦点。
I'm trying to use window.blur() to open a window without focus it (or focus and unfocus really fast, so looks like it was not focused).
But it looks like it doesn't work, is there an alternative?
My attempt:
blurTest.xul:
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
<window width="400" height="300"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<script>
<![CDATA[
function onkeypress(event) {
// for this sample don't matter which key is pressed
open('second.xul','SecondWindow','chrome, width=400, height=300');
}
addEventListener("keypress", onkeypress, false);
]]>
</script>
<label value="MAIN WINDOW"/>
</window>
second.xul:
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
<window width="400" height="300"
onload="blur();"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<label value="SECOND" />
</window>
Obs. We can think about use setTimeout(window.focus, 1) to call the focus back the my window after open the second window. But I need the second window to handle the focus. The perfect scenario would be if the second window was never able to get the focus, just open/restore the window without get focus.

您可以使用
openDialog调用中的popup窗口功能打开 XUL 窗口，就好像它是弹出窗口一样。这应该会打开一个不会窃取焦点的最顶层窗口。请注意，默认情况下，弹出窗口没有操作系统镶边；在 Windows 上，您可以添加titlebar功能（它为您提供一个类似于调色板窗口的迷你标题栏）和close按钮（与标题栏结合使用），但是我不知道哪些功能标志可以在其他平台上使用。桌面警报在 Windows 上仍然使用此功能，但我相信在 Linux 上他们现在使用 libnotify，在 Mac 上他们使用 Growl。
You can open a XUL window as if it was a popup by using the
popupwindow feature in theopenDialogcall. This should open a topmost window that doesn't steal focus. Note that by default a popup window has no OS chrome; on Windows you can add thetitlebarfeature (which gives you a mini title bar as for a palette window) and theclosebutton (in conjunction with the title bar), but I don't know which feature flags work on other platforms.Desktop alerts still use this feature on Windows but I believe on Linux they now use libnotify and on the Mac they use Growl.
