JavaScript彈出窗口（背景窗口）

Question

我打開彈出窗口使用Java腳本在當前活動屏幕後面。 這是我的簡單代碼。

var win = window.open('http://yahoo.com',null,"height=400,width=600,status=yes,toolbar=no,scrollbars=yes,menubar=yes,location=yes"); 
win.blur(); 
this.window.focus(); 

但它似乎並不適用於任何瀏覽器。它只是打開一個彈出窗口。我從stackoverflow中提到this question。但它不起作用。我的目標是在所有瀏覽器中創建一個背景窗口。有人請幫助我

Answer 1

你不能這樣做。現代Web瀏覽器不允許網站從其他選項卡中竊取焦點（因爲這對用戶來說可能會變得相當混亂）。唯一可以做的是提示用戶在新標籤中打開（這不會改變焦點）。或者你可以濫用警報找回焦點到您的網頁：

var win = window.open('http://yahoo.com',null,"target=_blank,height=400,width=600,status=yes,toolbar=no,scrollbars=yes,menubar=yes,location=yes"); 
alert("Welcome back");
