JS分页方法

 1 function paging(index,totalNum)
 2 {
 3     pageTotal = Math.ceil(totalNum / pagesize);//总的页数
 4     var htmlShow = ‘‘;//页码
 5     var top = index == 1 ? 1 : parseInt(index - 1);
 6     var buttom = index == pageTotal ? pageTotal : parseInt(index + 1);
 7     htmlShow += "<li><a class=‘words wandn‘ href=‘javascript:void(0);‘  onclick=serach(1)>首页</a>";
 8     htmlShow += "<a class=‘words wandn‘ href=‘javascript:void(0);‘  onclick=serach(" + top + ")> <上页</a><span id=‘htmlnum‘></span>";
 9     //判断显示的页码
10     var indexTop = Math.floor((index-1) / 5);
11     var index5 = parseInt(indexTop * 5 + 5) > pageTotal ? pageTotal : parseInt(indexTop * 5 + 5);
12     htmlShow += "<a class=‘words wandn‘ href=‘javascript:void(0);‘ onclick=serach(" + buttom + ")>下页></a>";
13     htmlShow += "<a class=‘words wandn‘ href=‘javascript:void(0);‘ onclick=serach(" + pageTotal + ")>末页</a>";
14     htmlShow += "<span class=‘fy‘>" + index + "/" + pageTotal + "</span><div class=‘zd_page‘>转到&nbsp;&nbsp;<input id=‘btnSelect‘/><div class=‘goout‘ id=‘go‘>GO</div></div></li>";
