//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";
