前端分页函数基于Ext的2.0.2版本

一套前端分页函数基于Ext的2.0.2版本
下载地址：http://extjs.com/deploy/ext-2.0.2.zip
需要导入Ext的js如下：
resources/css/ext-all.css
adapter/ext/ext-base.js
ext-all.js
build/locale/ext-lang-zh_CN.js

<script type="text/javascript">
var iTotlePg = parseInt("得到总页数totalpage");
//首次加载进行设置
function setPageList()
{
	while(document.getElementById("_page_list").options.length > 0) //清空选中项
	{
		document.getElementById("_page_list").options.remove(0);    
	} 
	for(var i = 1; i <= iTotlePg; i++) //set select options
	{
	    newObj = new Option(i,i);            
	    document.getElementById("_page_list").add(newObj);       
	} 
	document.getElementById("_page_list").selectedIndex = parseInt("得到当前页数iCurrentPage") - 1;
	var total=parseInt("得到总记录数iTotalCount");
	var beFirst="No";
	if(total>10000 && beFirst=="Yes")
	{
		Ext.MessageBox.alert("", "本次查询满足条件的记录数过多,系统只能显示和导出前一万条记录,请缩小查询条件后继续查询。");
	}

页面注意在body中初始化setPageList()函数

<body onload="setPageList()">
<form action="#" name="formName" method="post">
<input type="hidden" value="1" name="iCurrentPage"/>
<table>
	<tr>
	    <td align="left" id="_tip"><div></div></td>
	    <td align="right" >
	    	<div class="table-label-text-r">

	      		<a href="javascript:previouspage();"  target="" onfocus="this.blur()">上一页</a>
		    	第[当前页数]页,共[总页数]页
	      		<a href="javascript:nextpage();"      target="" onfocus="this.blur()">下一页</a>
	      		<a href="javascript:lastpage();"      target="" onfocus="this.blur()">尾页</a>
			</div>

	    <td width="3%"><div>&nbsp;&nbsp;跳转</div></td>
	    <td width="3%"><select id="_page_list" style="width:80px" onchange="gotoPage(this);"></select></td>
