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

<script type="text/javascript">
        function mine(dom){
            dom.style.background="red";
        }
        function myout(dom){
            dom.style.background="";
        }
    </script>
  </head>
  
  <body>
    <ul>
        <li onmouseover="javascript:mine(this)" onmouseout="javascript:myout(this)"></li>
        <li onmouseover="javascript:mine(this)" onmouseout="javascript:myout(this)"></li>
        <li onmouseover="javascript:mine(this)" onmouseout="javascript:myout(this)"></li>
    </ul>
  </body>

3、使用javascript得到按键的ASCⅡ值。

<script type="text/javascript">

    </script>
  </head>
