JQuery AJAX 分页，跳页下一页，上一页【总结了一天啊干货】

网上的分页基本有问题，自己总结下：代码如下

<script type="text/javascript">
var pagesi = "2";//每页行数
var totalPage = "0";//总页数
var currentPage = "1";//当前页 
    $(function(){
                $('.menu_item').click(function () {
                    $('.menu_item').removeClass('selected');
                    $(this).addClass('selected');
                });
                
                $('.js_top').click(function () {
                    $('.js_top').removeClass('selected');
                    $(this).addClass('selected');
                });


    			$('#commentList').click(function(){
    				queryForPages();
    			});
    			
    			 //上一页
    		    $(".page_prev").click(function(){
	    		    if(currentPage>1){
	    		    currentPage-- ;
	    		    $(".page_prev").css({display:"inline-block"});
	    		    queryForPages();
	    		    }
					if(currentPage==1){
	    		    	$(".page_prev").hide();
	    		    }
					if(currentPage<totalPage){
		    		    $(".page_next").css({display:"inline-block"});
	    		    }
    		    });
    		    //下一页
    		    $(".page_next").click(function(){
	    		    if(currentPage<totalPage){
		    		    currentPage++ ;
		    		    $(".page_next").css({display:"inline-block"});
		    		    queryForPages();
	    		    }
	    		    if(currentPage>1){

    		    }); 
    		    //跳页
    		    $('.page_go').click(function(){
    		    	currentPage = $('.goto_area').find('input').val();
    		    	queryForPages();
    		    	if(currentPage==1){
	    		    	$(".page_prev").hide();
	    		    }
    		    	 if(currentPage>1){
 	    		   	 	$(".page_prev").css({display:"inline-block"});
 	    		    }
    		    	if(currentPage<totalPage){
		    		    $(".page_next").css({display:"inline-block"});
