jsp分页技术

//初始化分页
function initPageResult(nPageIndex,nPageSize,nCount,tbody){
	var html = [];
	var nCountPage = (nCount%nPageSize==0)?(nCount/nPageSize):(nCount/nPageSize)+1;//总页数
	nCountPage = parseInt(nCountPage);
		//总页数
		html.push('<div class="page_main"><span>共有 '+nCount+' 条记录</span>  ');
		//上一页
		var prevPage = (nPageIndex>1)?'<a href="javascript:void(0)" οnclick="query('+(nPageIndex-1)+')">上一页</a>':'<span style="color:#CCCCCC;">上一页</span>';
		html.push(prevPage);
		//第一页及省略页
		if (nPageIndex-3>1){
			html.push('<a href="javascript:void(0)" οnclick="query('+1+')">'+1+'</a>');
			if (nPageIndex-3>2){
				html.push("<span>...</span>");
			}
		}
		//当前页前3页
		for(var i=3;i>=1;i--){
			if (nPageIndex-i>=1){
				html.push('<a href="javascript:void(0)" οnclick="query('+(nPageIndex-i)+')">'+(nPageIndex-i)+'</a>');
