WeixinJSBridge.call('closeWindow');

普通网页：

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();
}
