“上页下页选择的页数：第页 GO“这段JSP代码如何写：选择的页数：第页 GO

答案：这个一般用javascript来写的 我给你一段我们练习的时候的代码给你,输入多少页在input的text文本框内做一个丢失焦点事件onblur="forward(this);"  然后用Javascript做一个函数,获得this.value就可以得到用户输入的多少页了.当然你也可以做一些数据格式效验,安全检测这些的,
<html>
	<head>
	<title>神马大作战</title>
		<script type="text/javascript" >
			function begin(){
				if(${param.pageIdx}<=1){
					document.getElementById("pre").disabled=true;
				}
				if(${param.pageIdx}>=2){
					document.getElementById("next").disabled=true;
				}
			}
			function prev(){
				window.location="/bank/queryAccountByPageIdx?pageIdx="+${param.pageIdx-1};
			}
			function next(){
				window.location="/bank/queryAccountByPageIdx?pageIdx="+${param.pageIdx+1};
			}
			function sall(){
				var checkBoxs = document.getElementsByTagName("input");
				for(idx in checkBoxs){
					if(checkBoxs[idx].type=="checkbox"){
						checkBoxs[idx].checked="checked";
					}
				}
			}
			function del(){
				var save="";
				var checkBoxs = document.getElementsByTagName("input");
				for(idx in checkBoxs){
					if((checkBoxs[idx].type=="checkbox")&&(checkBoxs[idx].checked="checked")){
						save += checkBoxs[idx].value+",";
					}
				}
				window.location="/bank/queryAccountByPageIdx?pageIdx="+${param.pageIdx}+"&save="+save;
			}
		</script>
	</head>
	<body onload="begin();">
		<div style="margin-left: 70">共${sum }页  第${param.pageIdx}页
			<input type="button" id="pre" value="上一页" onclick="prev();" />
			<input type="button" id="next" value="下一页" onclick="next();"/>
		</div> 
		
			<cq:loopView pageSize="10" pageIdx="${param.pageIdx}"/>
	
		<div style="margin-left: 70">
			<input type="button" id="sall" value="全选" onclick="sall();" />
			<input type="button" id="del" value="删除" onclick="del();"/>
		</div>
	</body>
</html>

我自己写了一个简易的tag也给你吧,你如果不要可以直接用jstl也可以,稍微改一下就可以了
public class LoopViewTag implements SimpleTag{
	private JspTag jspTag;
	private JspContext jspContext;
	private int pageSize;
	private int pageIdx;
	private JspFragment jf;
	
	/**
	 * <loopTag pageIdx=? pageSize=? /> || <loopTag pageIdx=? pageSize=? tableName=? />
	 */
	public void doTag() throws JspException, IOException {
		AccountService accountService = new AccountServiceImpl();
		List<Account> as = accountService.QueryAccountByPageidx(pageIdx, pageSize);
		JspWriter out = jspContext.getOut();
		out.print("<center><table border=1  cellspacing='0'  width='920' cellspacing='0' cellspadding='0' style='border-style: solid'>");
		out.print("<tr height='20' bgcolor='gray'>");
		out.print("<td width='20'></td><td width='100'>用户</td><td width='100'>密码</td><td width='100'>卡号</td><td width='100'>余额</td><td width='200'>注册时间</td><td width='100'>电话</td><td width='200'>所在地</td></tr>");
		for (Account account : as) {
			out.print("<tr height='20'>");
			out.print("<td>");
			out.print("<input type='checkbox' value='"+account.getName()+"'/>");
			out.print("</td>");
			out.print("<td>");
			out.print(account.getName());
			out.print("</td>");
			out.print("<td>");
			out.print(account.getPwd());
			out.print("</td>");
			out.print("<td>");
			out.print(account.getCardId());
			out.print("</td>");
			out.print("<td>");
			out.print(account.getMoney());
			out.print("</td>");
			out.print("<td>");
			out.print(account.getRegTime());
			out.print("</td>");
			out.print("<td>");
			out.print(account.getPhone());
			out.print("</td>");
			out.print("<td>");
			out.print(account.getAddress());
			out.print("</td>");
			out.print("</tr>");
		}
		out.print("</table></center>");
	}

	public JspTag getParent() {
		return jspTag;
	}

	public void setParent(JspTag jspTag) {
		this.jspTag = jspTag;
	}
	
	public void setJspBody(JspFragment jf) {
		this.setJf(jf);
	}

	public void setJspContext(JspContext jspContext) {
		this.jspContext = jspContext;
	}

	public JspTag getJspTag() {
		return jspTag;
	}

	public void setJspTag(JspTag jspTag) {
		this.jspTag = jspTag;
	}

	public JspContext getJspContext() {
		return jspContext;
	}

	public int getPageSize() {
		return pageSize;
	}

	public void setPageSize(int pageSize) {
		this.pageSize = pageSize;
	}

	public int getPageIdx() {
		return pageIdx;
	}

	public void setPageIdx(int pageIdx) {
		this.pageIdx = pageIdx;
	}

	public void setJf(JspFragment jf) {
		this.jf = jf;
	}

	public JspFragment getJf() {
		return jf;
	}
	
}

其他：有可能
1：通过name查找，有重复
2：添加的点击事件的写法，当前浏览器不支持
