代码如下:

function hidepic(){

 var mychar = document.getElementById("con");

 mychar.style.diplay="none";

}

function showpic(){

 var mychar = document.getElementById("con");

  mychar.style.display="block";

}

HTML:

    <div class="main2">

      <div id="con" ><h1>My Photo</h1>

      <div class="img"><img src="http://www.huangxiaolong.net/wp-content/uploads/2015/07/psb.jpg" height="657px" width="370"></div><br/>

      He is ugly.<input type="button" onClick="hidepic" value="Click disappear" /> 

     Is cool.<input type="button" onClick="showpic" value="Look again" />

    </div></div>
