The example in this article describes how to use JavaScript to automatically pop up a window and automatically close the window. Share it with everyone for your reference. The details are as follows:

The JavaScript introduced here automatically pops up the window and automatically closes the window. It seems very simple to achieve this special effect with JS. After opening the web page, a pop-up window will be displayed, and then it will automatically leave. Use window.open and document.open(); and document.close(); is implemented together with objects, but it seems that it is not used much now.

The operation effect is as shown below:

The specific code is as follows:

<HTML>
<HEAD>
<TITLE>自动离开的窗口</TITLE>
<SCRIPT>
<!--
var flyingwin
var popupwidth=200
var popupheight=150
var marginright
var windowcenter
var i_top=200
var i_left=-popupwidth-50
var step=40
var timer
var waitingtime=5000
var pause=20
function showWindow() {
 flyingwin = window.open("", "flyingwin", "toolbar=no,width="+popupwidth+",height="+popupheight+",top=100,left="+(-popupwidth)+"");
 flyingwin.document.open();
 flyingwin.document.write("<html><title>自动离开的窗口</title><body><p align=center>请不要关闭，马上就离开:(</body></html>");
 flyingwin.document.close();
 if (document.all) {
  marginright = screen.width+50
 }
 if (document.layers) {
  marginright = screen.width+50
 }
 windowcenter=Math.floor(marginright/2)-Math.floor(popupwidth/2)
 movewindow()
}
function movewindow() {
  if (i_left<=windowcenter) {
   flyingwin.moveTo(i_left,i_top)
   i_left+=step
   timer= setTimeout("movewindow()",pause)
  }
  else {
   clearTimeout(timer)
   timer= setTimeout("movewindow2()",waitingtime)
  }
}
function movewindow2() {
  if (i_left<=marginright) {
   flyingwin.moveTo(i_left,i_top)
   i_left+=step
   timer= setTimeout("movewindow2()",pause)
  }
  else {
   clearTimeout(timer)
   flyingwin.close()
  }
}
// -->
</SCRIPT>
</HEAD>
<BODY onload=showWindow()> </BODY>
</HTML>
