jquery+ajax实现分页

var curPage = 1; //当前页码 
	var total,pageSize,totalPage; //总记录数，每页显示数，总页数
	getData(1);
	$("#pagecount").on('click','span a',function(){
		var rel = $(this).attr("rel");
		if(rel){
			getData(rel);
		}
	});
	function getData(page){ 
		$.ajax({
			url:ThinkPHP['MODULE']+'/Votesubject/getVotesubjectList',
			type:'POST',
			data: {'pageNum':page-1},
			beforeSend:function(){
				
			},
			success:function(json){
				// console.log(json);
				total = json.total; //总记录数
				pageSize = json.pageSize; //每页显示条数
				curPage = page; //当前页
				totalPage = json.totalPage; //总页数
				var ul=$('.theme_body').find('*').remove();
				string='';
				$.each(json.list,function(index,array){ //遍历json数据列
					string+='';
					
				});
				$('.theme_body').append(string);
				
			},
			complete:function(){ //生成分页条
				getPageBar();
			},
			error:function(){
				alert("数据加载失败");
			}
		});
	}
	//获取分页条
function getPageBar(){
	$("#pagecount").find('*').remove();
	//页码大于最大页数
	if(curPage>totalPage) curPage=totalPage;
	//页码小于1
	if(curPage<1) curPage=1;
	pageStr = "<span>共"+total+"条</span><span>"+curPage+"/"+totalPage+"</span>";
	
	//如果是第一页
	if(curPage==1){
		pageStr += "<span>首页</span><span>上一页</span>";

	//如果是最后页
	if(curPage>=totalPage){
