我初学jvascript,按照书上编了个例程不能运行,整个页面都是空白,(我点击允许运行插件了)但是别人机器上可以.我的浏览器是IE7.0,是不是设置上有什么问题?高手解答下.我今天下午问这个问题已经没分了,所以不能给回答的高手加分了,对不起了.程序源码如下:
<html>
<head>
<script language="JavaScript">
var aBoy= "Charlie Brown"
var hisDog= "snoopy"
function demo(){
var hisDog="Gromit"
var output=hisDog+"does not belong to"+aBoy+".<br>"
document.write(output)
}
</script>
</head>
<body>
<script language="JavaScript">
<!--
demo()
document.write(hisDog+"belongs to"+aBoy+".")
</script>
//-->
</body>
</html>
<html>
<head>
<script language="JavaScript">
var aBoy= "Charlie Brown"
var hisDog= "snoopy"
function demo(){
var hisDog="Gromit"
var output=hisDog+"does not belong to"+aBoy+".<br>"
document.write(output)
}
</script>
</head>
<body>
<script language="JavaScript">
<!--
demo()
document.write(hisDog+"belongs to"+aBoy+".")
</script>
//-->
</body>
</html>
<html>
<head>
<script language="JavaScript">
var aBoy= "Charlie Brown"
var hisDog= "snoopy"
function demo(){
var hisDog="Gromit"
var output=hisDog+"does not belong to"+aBoy+".<br>"
document.write(output)
}
</script>
</head>
<body>
<script language="JavaScript">
<!--
demo()
document.write(hisDog+"belongs to"+aBoy+".")
//-->
</script>
</body>
</html>
这样就可以了，你把
</script>
//-->
前后位置搞错了
按你原来的样就相当于把
demo()
document.write(hisDog+"belongs to"+aBoy+".")
</script>
给注释掉了，明白了吧
<html>
<head>
<script language="JavaScript">
var aBoy= "Charlie Brown"
var hisDog= &quo
