javascript實(shí)現(xiàn)表格隔行換色

這篇文章為大家分享了javascript實(shí)現(xiàn)表格隔行換色的代碼，文中示例代碼介紹的非常詳細(xì)，零基礎(chǔ)也能參考此文章，感興趣的小伙伴們可以參考一下。

創(chuàng)新互聯(lián)成立10余年來(lái)，這條路我們正越走越好，積累了技術(shù)與客戶(hù)資源，形成了良好的口碑。為客戶(hù)提供網(wǎng)站設(shè)計(jì)、成都網(wǎng)站建設(shè)、網(wǎng)站策劃、網(wǎng)頁(yè)設(shè)計(jì)、域名與空間、網(wǎng)絡(luò)營(yíng)銷(xiāo)、VI設(shè)計(jì)、網(wǎng)站改版、漏洞修補(bǔ)等服務(wù)。網(wǎng)站是否美觀、功能強(qiáng)大、用戶(hù)體驗(yàn)好、性?xún)r(jià)比高、打開(kāi)快等等，這些對(duì)于網(wǎng)站建設(shè)都非常重要，創(chuàng)新互聯(lián)通過(guò)對(duì)建站技術(shù)性的掌握、對(duì)創(chuàng)意設(shè)計(jì)的研究為客戶(hù)提供一站式互聯(lián)網(wǎng)解決方案，攜手廣大客戶(hù)，共同發(fā)展進(jìn)步。

首先我們來(lái)看一下實(shí)現(xiàn)的效果，如下圖所示：

思路：

確定事件: 文檔加載完成 onload 2. 事件要觸發(fā)函數(shù): init() 3. 函數(shù):操作頁(yè)面的元素要操作表格中每一行動(dòng)態(tài)的修改行的背景顏色

具體代碼：

<!DOCTYPE html>
<html>
<head>
  <meta charset="UTF-8">
  <title>Title</title>
  <script >
    function init(){
      //得到表格
      var tab = document.getElementById("tab");
      //得到表格中每一行
      var rows = tab.rows;
      //便利所有的行,然后根據(jù)奇數(shù) 偶數(shù)
      for(var i=1; i < rows.length; i++){
        var row = rows[i]; //得到其中的某一行
        if(i%2==0){
          row.bgColor = "yellow";
        }else{
          row.bgColor = "red"
        }
      }
    }
  </script>
</head>
