用JS生成動態(tài)生成表格，行、列由用戶輸入，并使表格隔行換色

方法一.

代碼:

<!DOCTYPE html><html> <head>  <title>動態(tài)表格</title>  <meta http-equiv="keywords" content="keyword1,keyword2,keyword3">  <meta http-equiv="description" content="this is my page">  <meta http-equiv="content-type" content="text/html; charset=UTF-8">  <!--<link rel="stylesheet" type="text/css" href="./styles.css" rel="external nofollow" rel="external nofollow" >-->  <script type="text/javascript">   function createTable(){      var table = document.createElement("table");      //添加邊框      table.border = "1";      table.width = "100%";      //table API      //創(chuàng)建一行      //var tr = table.insertRow(table.rows.length);      //創(chuàng)建單元格      //var td = tr.insertCell(tr.cells.length);        //行，單元格        var tr,td;         //獲得行列值        var tr_value = document.getElementById("tr_value").value;        var td_value = document.getElementById("td_value").value;      for(var i=0;i<tr_value;i++){        //循環(huán)插入元素        tr = table.insertRow(table.rows.length);        if(i%2 === 0){          tr.style.backgroundColor = "#D5E3D0";        }else{          tr.style.backgroundColor = "#909C97";        }        for(var j=0;j<td_value;j++){          td = tr.insertCell(tr.cells.length);          td.innerHTML = "_";          td.align = "center";        }      }      //td.innerHTML = "測試";      document.querySelector("#tb").appendChild(table);    }  </script> </head> <body> <input type="text" id="tr_value">輸入行數 <input type="text" id="td_value">輸入列數<input type="button" onclick="createTable()"； value="createTable"><hr><div id="tb"></div> </body></html>

運行結果:

輸入行數、列數，create Table:
