1、onclick="javascript:window.close();"在Chrome中不起作用
https://developer.mozilla.org/en-US/docs/Web/API/Window/close
The Window.close() method closes the current window, or the window on which it was called.
This method is only allowed to be called for windows that were opened by a script using the window.open() method. If the window was not opened by a script, an error similar to this one appears in the console: Scripts may not close windows that were not opened by script.
所以window.close()不能打开不是使用window.open()打开的页面。如果想要把非window.open()打开的页面关闭，可以把window.close()改为：
window.open("about:blank","_self").close();
2、使用javascript实现光棒效果
