本文實例為大家分享了javascript實現(xiàn)前端分頁效果的具體代碼，供大家參考，具體內(nèi)容如下

需求：實現(xiàn)分頁請求表格數(shù)據(jù)，ajax暫時沒寫，只寫了分頁的功能。

效果圖：

當(dāng)頁數(shù)是第一頁的時候，首頁和向前那個按鈕處于禁止點擊的狀態(tài)

各個按鈕都正常的狀態(tài)

當(dāng)頁數(shù)是第一頁的時候，首頁和向前那個按鈕處于禁止點擊的狀態(tài)

各部分的代碼如下：

html部分：

<!-- 分頁 --> <div class='pageBox'> <div class='pageTotal'>共<span id='dataLength'>88</span>條</div> <div class='pageContent'> <button class=’firstPage’>首頁</button> <button class='prevPage'></button> <button class='showPage'></button> <button class='nextPage'></button> <button class='lastPage'>尾頁</button> </div> <div class='selectSize'> <div><span class='numSelect'>10</span> <span>條/頁</span></div> <div class='icona'></div> </div> <!-- <div style='display: inline-block;margin-left: 210px;'></div> --> <div class='goPage'><span>跳至</span><input type='text' id='goPageInp'><span>頁</span></div> <ul class='pageSelectShow'> <li data-num='10'>10條/頁</li> <li data-num='20'>20條/頁</li> <li data-num='50'>50條/頁</li> <li data-num='100'>100條/頁</li> </ul> </div>

CSS部分：
