按照javascript dom 编程艺术关于网页显示图片的那部分内容敲出来的代码,其中有一段需要输入onclick="showPic(this);return false;"用于阻止网页弹出新的链接来查看图片,但是最后运行的时候还是弹出新的链接了,具体代码如下:<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"/> <title>My Gallery</title> </head> <body> <h1>snapshots</h1> <ul> <li> <a href="images/do or die.jpg" onclick="showPic(this);return false;" title="do or die">DO</a> </li> <li> <a href="images/hand.jpg" onclick="showPic(this);return false;" title="hand">HAND</a> </li> <li> <a href="images/phrase.jpg" onclick="showPic(this);return false;" title="phrase">Phrase</a> </li> </ul> <img id="placeholder" src="images/dog.jpg" alt="My Gallery"/> <script> function showPic(whichpic) {var source=whichpic.getAttribute ("href"); var placeholder=document.getElenmentById ("placeholder"); placeholder.setAttribute("src",source);} </script> </body> </html>

首先是你的id获取单词都拼错了,其次是a标签href指向问题和点击事件冲突
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<title>My Gallery</title>
</head>
<body >
<h1>snapshots</h1>
<ul>
<li> <a href="javascript:;" date-href="zhc1.jpg" onclick="showPic(this);return false;" title="do or die">DO</a> </li> <li> <a href="javascript:;" date-href="zhc2.jpg" onclick="showPic(this);return false;" title="hand">HAND</a> </li> <li> <a href="javascript:;" date-href="zhc3.jpg" onclick="showPic(this);return false;" title="phrase">Phrase</a> </li>
</ul>
<img id="placeholder" src="zixun_video_pic.jpg" alt="My Gallery"/>
<script>
function showPic(whichpic){ var source=whichpic.getAttribute ("date-href"); var placeholder=document.getElementById ("placeholder"); placeholder.setAttribute("src",source); }
</script>
</body>
</html>
