前言前言最近的项目需要添加一个分页导航的功能，没有用网上封装好的文件。通过JS自己简单实现了效果。下面和大家分享一下。内容内容下图为首次加载后的效果，默认显示5页，当点击下一页时将选中页面的页码置于中间下面让我们来看看实现的代码第一部分是在页面显示内容的处理第一部分第一部分
function SetListPage() {

$.ajax({

type: "GET",

url: "ajax/PhoneList.ashx?",

datatype: 'json',

success: function (data, textStatus) {

var li_list = "";

if (data != "") {

var cc = jQuery.parseJSON(data);
//转换Json对象

var pagesize = 6;
//设置每页显示数

var pagecount = Math.ceil(cc.length / pagesize); //获取页数

SetPageCount(pagecount);
//设置跳转页签

for (var j = 0, l = pagecount; j < l; j++) {
//设置页面内容

if (j == 0) {

li_list += "";

}

else {

li_list += "";

}

li_list += "";

li_list += "";

li_list += "";

li_list += "";

li_list += " ";

var index = j * pagesize;

var rowcount = j * pagesize + pagesize;

if (rowcount > cc.length) {

rowcount = cc.length;

}

for (var i = index; i < rowcount; i++) {

var Name = cc[i]['Name'];

var PhoneNO = cc[i]['PhoneNO'];

var Email = cc[i]['Email'];

li_list += "";

li_list += "";

li_list += "";

li_list += "";

li_list += " ";

}

li_list += "

姓名	手机号码	邮箱
" + Name + "	" + PhoneNO + "	" + Email + "

";

}

}


}

});
}
function SetListPage() {

$.ajax({

type: "GET",

url: "ajax/PhoneList.ashx?",

datatype: 'json',

success: function (data, textStatus) {

var li_list = "";

if (data != "") {

var cc = jQuery.parseJSON(data);
//转换Json对象

var pagesize = 6;
//设置每页显示数

var pagecount = Math.ceil(cc.length / pagesize); //获取页数

SetPageCount(pagecount);
//设置跳转页签

for (var j = 0, l = pagecount; j < l; j++) {
//设置页面内容

if (j == 0) {

li_list += "";

}

else {

li_list += "";

}

li_list += "";

li_list += "";

li_list += "";

li_list += "";

li_list += " ";

var index = j * pagesize;

var rowcount = j * pagesize + pagesize;

if (rowcount > cc.length) {

rowcount = cc.length;

}

for (var i = index; i < rowcount; i++) {

var Name = cc[i]['Name'];

var PhoneNO = cc[i]['PhoneNO'];

var Email = cc[i]['Email'];

li_list += "";

li_list += "";

li_list += "";

li_list += "";

li_list += " ";

}

li_list += "

姓名	手机号码	邮箱
" + Name + "	" + PhoneNO + "	" + Email + "

";

}

}


}

});
}第二部分是动态的设置页码并添加页码导航的方法第二部分第二部分
function SetPageCount(count) {

if (count > 0) {
//设置动态页码

var li_list = "";

li_list += "

";

li_list += "
• 上一页
";

li_list += "
• ";
  
  li_list += "
  • 1
  ";
  
  for (var i = 2; i <= count; i++) {
  
  if (i <= 5) {
  
  li_list += "
  • " + i + "
  ";
  
  } else {
  
  li_list += "
  • " + i + "
  ";
  
  }
  
  }
  
  li_list += "
";

li_list += "
• 下一页
";

li_list += "

";

if (li_list != null && li_list.length > 0) {

$("#PhonePageCount").html(li_list);

}小结小结一个小小的功能，在实现的过程中并不容易不断的调试和优化才让这样的需求得到了合理的实现。但敲代码中也让我的感受到了页面导航中所需要考虑到的多元素设计。以上就是本文的全部内容，希望对大家的学习有所帮助。
