這篇文章主要分享一個(gè)自己寫的簡單的javascript分頁組件，效果十分不錯(cuò)，代碼也很詳盡，這里推薦給小伙伴們。
    自己寫的一個(gè)簡單的分頁組件,主要功能還有實(shí)現(xiàn)都在JS中,html頁面中只用增加一個(gè)放置生成分頁的DIV,并給定容器的id.
    html結(jié)構(gòu)如下:
    代碼如下:
    <ul id="pageDIV">
    </ul>
    class="pagination" 給定了分頁的樣式,
    id="pageDIV"用于放置JS生成的分頁
    CSS結(jié)構(gòu)如下:
    代碼如下:
    .pagination{
    margin-top: 10px;
    margin-bottom: 10px;
    display: inline-block;
    padding-left: 0;
    margin: 20px 0;
    border-radius: 4px;
    }
    .pagination>li {
    display: inline;
    }
    .pagination>li:first-child>a{
    margin-left: 0;
    border-top-left-radius: 4px;
    border-bottom-left-radius: 4px;
    }
    .pagination>li>a{
    position: relative;
    float: left;
    padding: 6px 12px;
    margin-left: -1px;
    line-height: 1.42857143;
    color: #337ab7;
    text-decoration: none;
    background-color: #fff;
    border: 1px solid #ddd;
    cursor: pointer;
    }
    .pagination>li>a.navcur{
    background: #cccccc;
    color: #ffffff;
    }
    下面是JS結(jié)構(gòu),注意要引用JQuery
    代碼如下:
    /**
    * @pageContentID 渲染分頁的DIV元素
    * @curPage 當(dāng)前開始頁
    * @totalCount 總數(shù)量
    * @pageRows 每頁顯示數(shù)量
    * @callback 顯示數(shù)據(jù)的回調(diào)函數(shù)
    */
    function PageList(pageContentID,option){

    totalCount:26,
    pageRows:1,
    callback:callbackFuc
    });
    pager.init();
    });
    function callbackFuc(curpage){
    }
    說明:
    此分頁是以10頁為標(biāo)準(zhǔn),低于10頁的時(shí)候全部顯示,大于10頁的時(shí)候,進(jìn)行翻頁顯示余下頁數(shù).
    調(diào)用方法:
    代碼如下:
    $(function(){
    var pager = new PageList("pageDIV",{
    curPage:1,
    totalCount:26,
    pageRows:1,
    callback:callbackFuc
    });
    pager.init();
    });
    以上就是本分頁組件的核心代碼了，希望小伙伴們能夠喜歡。
