分页按钮思想:
1、少于9页,全部显示
2、大于9页,1、2页显示,中间页码当前页为中心,前后各留两个页码

先看效果图:
01输入框焦点效果
02效果
模仿淘宝的分页按钮效果控件kkpager JS代码:
- var kkpager = {
- //divID
- pagerid : 'div_pager',
- //当前页码
- pno : 1,
- //总页码
- total : 1,
- //总数据条数
- totalRecords : 0,
- //是否显示总页数
- isShowTotalPage : true,
- //是否显示总记录数
- isShowTotalRecords : true,
- //是否显示页码跳转输入框
- isGoPage : true,
- //链接前部
- hrefFormer : '',
- //链接尾部
- hrefLatter : '',
- /****链接算法****/
- getLink : function(n){
- //这里的算法适用于比如:
- //hrefFormer=http://www.xx.com/news/20131212

html调用代码:
- <div id="div_pager"></div>
- <script type="text/javascript">
- //生成分页控件
- kkpager.init({
- pno : '${p.pageNo}',
- //总页码
- total : '${p.totalPage}',
- //总数据条数
- totalRecords : '${p.totalCount}',
- //链接前部
- hrefFormer : '${hrefFormer}',
- //链接尾部
- hrefLatter : '${hrefLatter}'
- });
- kkpager.generPageHtml();
- </script>
以上是示例中是必传参数,页码、总页数、总记录数这些是要根据获取服务端pager对象当相关值,还有可选的参数:pagerid、isShowTotalPage、isShowTotalRecords、isGoPage、getLink
注意链接算法哟,以下是默认链接算法(这个getLink方法也可以作为config参数):
- /****默认链接算法****/
- getLink : function(n){
- //这里的算法适用于比如:
- //hrefFormer=http://www.xx.com/news/20131212
- //hrefLatter=.html
- //那么首页(第1页)就是http://www.xx.com/news/20131212.html
- //第2页就是http://www.xx.com/news/20131212_2.html
- //第n页就是http://www.xx.com/news/20131212_n.html
- if(n == 1){
- return this.hrefFormer + this.hrefLatter;
- }else{
- return this.hrefFormer + '_' + n + this.hrefLatter;
- }
- }
CSS代码:
- #div_pager{
- clear:both;
- height:30px;
- line-height:30px;
- margin-top:20px;
- color:#999999;
- }
- #div_pager a{
- padding:4px 8px;
- margin:10px 3px;
- font-size:12px;
- border:1px solid #DFDFDF;
- color:#9d9d9d;
- text-decoration:none;
- }
- #div_pager span{
- padding:4px 8px;
- margin:10px 3px;
- font-size:14px;
- }
- #div_pager span.disabled{
- padding:4px 8px;
- margin:10px 3px;
- font-size:12px;
- border:1px solid #DFDFDF;
- color:#DFDFDF;
- }
- #div_pager span.curr{
- padding:4px 8px;
- margin:10px 3px;
- font-size:12px;
- border:1px solid #FF6600;
- color:#FFF;
- }
- #div_pager a:hover{
- border:1px solid #FF6600;
- }
- #div_pager span.normalsize{
- font-size:12px;
- }
效果图:
1、没有数据或只有一页数据时效果
2、有多页时当效果
3、第5页效果
4、第6页效果(分页效果2)
5、第17页效果(接近尾页效果)
6、尾页效果
7、输入框焦点效果
最后注意,若要使用,使用时请修改分页获取链接当算法,不然不适用哟
里面输入框我把ID写死了,样式也是写当行内样式,懒得提取出来了,影响不大,各位看官若要用自己再修修,呵呵
