js收集

1.关闭窗口或返回上一页

        function CloseWin() {
            if (window.opener) {
                window.opener = null;
                window.open('', '_self');
                window.close();
            }
            else {
                window.history.go(-1);
            }
        }

 2.在A窗口中打开B窗口，在B窗口中操作完以后关闭B窗口，同时自动刷新A窗口

B
function closeWin(){
         hasClosed = true;
         window.opener.location="javascript:reloadPage();";
         window.opener=null;
         window.close();
     }
     function window.onbeforeunload(){
         if(!hasClosed){//如果已经执行了closeWin方法，则不执行本方法
             window.opener.location="javascript:reloadPage();";
         }
     }
A
reloadPage方法如下:
function reloadPage() {
         history.go(0);
         document.execCommand("refresh")
         document.location = document.location;
         document.location.reload();
     }
