打开和关闭JavaScript窗口 [英] open and close javascript window

问题描述

我想关闭一个浏览器窗口，无论它在打开中。是新的JavaScript的，所以帮助我创建使用JavaScript的以下逻辑。我的JavaScript代码在这里：

  if（myWindow.open（）== true）{
 myWindow.close ）; 
} else {
 myWindow = window.open（'http：//index.html'，
'popUpWindow'，
'height = 700，width = 800，left = 10，top = 10，resizable = yes，scrollbars = yes，toolbar = yes，menubar = no，location = no，directories = no，status = yes'
）; 
 
  

解决方案使用 closed 属性来检查窗口状态，但首先检查窗口对象是否已创建。

  var myWindow = null; 
 if（myWindow&！myWindow.closed）{// exists and not closed 
 myWindow.close（）; 
 myWindow = null; //删除对象
} else {//不存在或被关闭
 myWindow = window.open（'http：//index.html'，$ b $'popUpWindow'，
'height = 700，width = 800，left = 10，top = 10，resizable = yes，scrollbars = yes，toolbar = yes，menubar = no，location = no，directories = no，status = yes'
 ）; 
} 
  

I want to close a browser window whether it is in open. Am new for javascript so help me to create the below logic using javascript. My JavaScript code is here:

if (myWindow.open() == true) {
    myWindow.close();
} else {
    myWindow=window.open('http://index.html',
                         'popUpWindow',
                         'height=700,width=800,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes'
                         );
}

解决方案

Use closed property to check the window status, but first check whether the window object has been created or not.

var myWindow=null;
if (myWindow && !myWindow.closed) { //exist and is not closed
    myWindow.close();
    myWindow=null; //delete the object
} else { //not exist or is closed
    myWindow=window.open('http://index.html',
                         'popUpWindow',
                         'height=700,width=800,left=10,top=10,resizable=yes,scrollbars=yes,toolbar=yes,menubar=no,location=no,directories=no,status=yes'
                        );
}
