//原理:所有数据已加载好,js通过遍历部分显示,实现分页效果

html代码

// 分页函数
// pno--页数
// size--每页显示记录数
// 分页部分是从真实数据行开始,因而存在加减某个常数,以确定真正的记录数
function Page(pno,size){
  var data = http://www.mamicode.com/document.getElementById("data");
  var num = data.rows.length;//表格所有行数(所有记录数)
  console.log(num);
  var totalPage = 0;//总页数
  var pageSize = size;//每页显示行数
//总共分几页
  if(num/pageSize > parseInt(num/pageSize)){
    totalPage=parseInt(num/pageSize)+1;
  }else{
    totalPage=parseInt(num/pageSize);
  }
//当前页数
  var currentPage = pno;
  var startRow = (currentPage - 1) * pageSize+1;//开始显示的行
  var endRow = currentPage * pageSize;//结束显示的行
  endRow = (endRow > num)? num : endRow; //三目运算符,
  console.log(endRow);//控制台打印出结束的行
//遍历显示数据实现分页
  for(var i=1;i<(num+1);i++){
    var irow = data.rows[i-1];
    if(i>=startRow && i<=endRow){
      irow.style.display = "block";
    }else{
      irow.style.display = "none";
    }
  }
  var pageEnd = document.getElementById("pageEnd");
  var tempStr = "共"+num+"条记录 分"+totalPage+"页 当前第"+currentPage+"页";
//判断页数>1时
  if(currentPage>1){
    tempStr += "<a href=http://www.mamicode.com/"#\" onClick=\"Page("+(1)+","+size+")\">首页</a>";
    tempStr += "<a href=http://www.mamicode.com/"#\" onClick=\"Page("+(currentPage-1)+","+size+")\"><上一页</a>"
  }else{
    tempStr += "首页";
    tempStr += "<上一页";
  }
//判断页数<总页数时
  if(currentPage<totalPage){
    tempStr += "<a href=http://www.mamicode.com/"#\" onClick=\"Page("+(currentPage+1)+","+size+")\">下一页></a>";
    tempStr += "<a href=http://www.mamicode.com/"#\" onClick=\"Page("+(totalPage)+","+size+")\">尾页</a>";
  }else{
    tempStr += "下一页>";
    tempStr += "尾页";
  }
  document.getElementById("con").innerHTML = tempStr;
