<a href='javascript:deleteCategory("<%=article.getId() %>")'>刪除</a>
?????
javascript函數(shù)<script>
?function deleteCategory(articleId)
?{
??if(confirm('是否真的要刪除該記錄'))
???window.location='<%=request.getContextPath()%>/info/infoArticleEdit.htm?order=delete&articleId='+articleId;
?}
</script>
一些鏈接：<input class="button3" type=button value="返回" onclick="javascript:window.location='<%=request.getContextPath() %>/info/infoArticleList.htm'">
<td>文件名：<a href='<%=request.getContextPath()%>/info/infoArticleEdit.htm?order=download&fileId=<%=accessory.getId() %>'><%=accessory.getFileExt() %></a>
?????
<c:url value="........" />
??
一些傳值
<input type=hidden name=order value=save>
<input type=hidden name=id value="<c:out value="${infoArticle.id}" />">
<input type=hidden name=navId value="<%=request.getParameter("navId") %>">
<input type=hidden name=fileCount value=1>

屬于：java.util包。
１、構造函數(shù)。
1. StringTokenizer(String str) ：構造一個用來解析str的StringTokenizer對象。java默認的分隔符是“空格”、“制表符(‘\t’)”、“換行符(‘\n’)”、“回車符(‘\r’)”。
2. StringTokenizer(String str, String delim) ：構造一個用來解析str的StringTokenizer對象，并提供一個指定的分隔符。
3. StringTokenizer(String str, String delim, boolean returnDelims) ：構造一個用來解析str的StringTokenizer對象，并提供一個指定的分隔符，同時，指定是否返回分隔符。
２、方法。
說明：
1. 所有方法均為public；
2. 書寫格式：［修飾符］ <返回類型> <方法名（［參數(shù)列表］）>
如：
static int parseInt(String s) 表示：此方法（parseInt）為類方法（static），返回類型為（int），方法所需參數(shù)為String類型。
1. int countTokens() ：返回nextToken方法被調(diào)用的次數(shù)。如果采用構造函數(shù)1和2，返回的就是分隔符數(shù)量(例2)。
2. boolean hasMoreTokens() ：返回是否還有分隔符。
3. boolean hasMoreElements() ：結果同2。
4. String nextToken() ：返回從當前位置到下一個分隔符的字符串。
5. Object nextElement() ：結果同4。
6. String nextToken(String delim) ：與4類似，以指定的分隔符返回結果。
例子：
String s = new String("The Java platform is the ideal platform for network computing");
StringTokenizer st = new StringTokenizer(s);
System.out.println( "Token Total: " + st.countTokens() );
while( st.hasMoreElements() ){
System.out.println( st.nextToken() );
}
結果為：
Token Total: 10
The
Java
platform
is
the
ideal
platform
for

例2:
String s = new String("The=Java=platform=is=the=ideal=platform=for=network=computing");
StringTokenizer st = new StringTokenizer(s,"=",true);
System.out.println( "Token Total: " + st.countTokens() );
while( st.hasMoreElements() ){
System.out.println( st.nextToken() );
}
結果為：
Token Total: 19
