当页面首次打开时,浏览器认为是不安全的并不能直接关闭当前窗口。这不是bug,有解释的链接:

只有当页面从别的页面打开时或者window.open()打开时,window.close()才起作用或则执行两次可关闭页面
不同的浏览器有不用的兼容问题
代码如下:
if (navigator.userAgent.indexOf(\'MSIE\') > 0) { // close IE
if (navigator.userAgent.indexOf(\'MSIE 6.0\') > 0) {
window.opener = null;
window.close();
} else {
window.open(\'\', \'_top\');
window.top.close();
}
} else { // close chrome;It is effective when it is only one.
window.opener = null;
window.open(\'\', \'_self\');
window.close();
}
