JavaScript 分页组件实现与样式详解

JavaScript 分页组件实现与样式详解

本文通过一个具体实例，详细解析了JavaScript分页工具的使用方法与实现原理，旨在为开发者提供可参考的代码方案。

接下来展示核心的JavaScript代码实现部分。

/**  
/** 分页JS模块 */
 */  
var Page;
  
(function(){
var Page = {version:"1.0",author:"liuxingmi"};
var showPage = 9;
Page.navigation = function(divId, totalRecord, totalPage, currentPage, func){
var nav = '<ul class="pagination" title="分页列表">';
nav += '<li class="totalAnnal">总记录数：<i id="totalRecord">' + totalRecord +'</i></li>';
nav += '<li class="totalPage">总页数：<i id="totalPage">' + totalPage + '</i></li>';
nav += '<li class="currentPage">当前页：<b id="pageNum">' + currentPage + '</b></li>';
if(currentPage == 1){
nav += '<li class="firstPage currentState"><a href="javascript:void(0);" id="firstPage" title="首页">首页</a></li>';
nav += '<li class="previousPage currentState"><a href="javascript:void(0);" id="frontPage" title="前一页">前一页</a></li>';
} else {
nav += '<li class="firstPage"><a href="javascript:' + func + '(1);" id="firstPage" title="首页">首页</a></li>';
nav += '<li class="previousPage"><a href="javascript:' + func + '('+ (currentPage -1) +');" id="frontPage" title="前一页">前一页</a></li>';
                   }  
nav += '<li id="num"><ol>';
var start = currentPage - Math.floor(showPage/2);
var end = currentPage + Math.floor(showPage/2);
if(end > totalPage){
start -= (end - totalPage);
                         }  
                           
if(start <= 0){
start = 1;
                         }  
if(currentPage < showPage && end < showPage){
end = showPage;
                         }  
                           
if(end > totalPage){
end = totalPage;
                         }  
for(var i = start; i <= end; i++){
if(i == currentPage){
nav += '<li class="currentState"><a title="转到第1页" href="javascript:' + func + '(' + i + ');">' + i + '</a></li>';
} else {
nav += '<li><a title="转到第1页" href="javascript:' + func + '(' + i + ');">' + i + '</a></li>';
                             }  
                         }  
                           
nav += '</ol></li>';
if(currentPage == totalPage){
nav += '<li class="nextPage currentState"><a href="javascript:void(0);" id="nextPage" title="后一页">后一页</a></li>';
nav +='<li class="lastPage currentState"><a href="javascript:void(0);" id="lastPage" title="尾页">尾页</a></i>';
} else {
nav += '<li class="nextPage"><a href="javascript:' + func + '('+ (currentPage + 1) +');" id="nextPage" title="后一页">后一页</a></li>';
nav +='<li class="lastPage"><a href="javascript:' + func + '(' + totalPage + ');" id="lastPage" title="尾页</a></i>';
                         }  
nav += '</ul>';
"$("#" + divId).html(nav);
        };  
this.Page = Page;
})();

接下来是配套的CSS样式代码部分。

/*分页样式开始*/
.pagination{
overflow:hidden;
margin:0 0 0 25px;
padding:10px 10px 6px 150px;
border-top:1px solid #c8c8c8;
_zoom:1;
text-align: center;
}  
.pagination *{
display:inline;
float:left;
margin:0;
padding:0;
font-size:12px;
}  
.pagination i{
float:none;
padding-right:1px;
}  
.currentPage b{
float:none;
color:#f00;
}  
.pagination li{
list-style:none;
margin:0 5px;
}  
.pagination li li{
position:relative;
margin:-2px 0 0;
font-family: Arial, Helvetica, sans-serif
}  
.firstPage a,.previousPage a,.nextPage a,.lastPage a{
overflow:hidden;
height:0;
text-indent:-9999em;
border-top:8px solid #fff;
border-bottom:8px solid #fff;
}  
.pagination li li a{
margin:0 1px;
padding:0 4px;
border:3px double #fff;
+border-color:#eee;
background:#eee;
color:#06f;
text-decoration:none;
}  
.pagination li li a:hover{
background:#f60;
border-color:#fff;
+border-color:#f60;
color:#fff;
}  
li.firstPage{
margin-left:40px;
border-left:3px solid #06f;
}  
.firstPage a,.previousPage a{
border-right:12px solid #06f;
}  
.firstPage a:hover,.previousPage a:hover{
border-right-color: #f60;
}  
.nextPage a,.lastPage a{
border-left:12px solid #06f;
}  
.nextPage a:hover,.lastPage a:hover{
border-left-color:#f60;
}  
.pagination li.lastPage{
border-right:3px solid #06f;
}  
.pagination li li.currentState a{
position:relative;
margin:-1px 3px;
padding:1px 4px;
border:3px double #fff;
+border-color:#f60;
background:#f60;
color:#fff;
}  
.pagination li.currentState,.currentState a,.currentState a:hover{
border-color:#fff #ccc;
cursor:default;
}  
/*分页样式结束*/

最后介绍该分页组件的调用方法。

Page.navigation("pageNav", 100, 10, 1, "xxxList");
<div id="pageNav"></div>

希望上述关于JavaScript分页工具的介绍与代码示例，能对各位在JavaScript程序设计方面的学习与实践有所帮助。
