jquery怎么增加列

append() 方法在被选元素的结尾(仍然在内部)插入指定内容。

语法

$(selector).append(content)
Copy after login

content 必需。规定要插入的内容(可包含 HTML 标签)。

使用函数在指定元素的结尾插入内容。

$(selector).append(function(index,html))
Copy after login

function(index,html)必需。规定返回待插入内容的函数。

示例如下:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>123</title>
<script src="js/jquery.min.js"></script>
</head>
<body>
<script>
function addCol() {  
            $col = $("<td>增加的列</td>");  
            $("tr").append($col);  
        }  
</script>
 <table border="1">
  <tr>
    <th>Month</th>
    <th>Savings</th>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
  <tr>
    <td>January</td>
    <td>$100</td>
  </tr>
</table>
<input id="Button1" type="button" onclick="addCol()" value="增加列" /> 
</body>
