-
<html> -
<head> -
<title>table添加/删除行</title> -
</head> -
<body> -
<table id="testTbl" border=1> -
<tr> -
<td>性别</td> -
<td>姓名</td> -
<td>年龄</td> -
</tr> -
<tr> -
<td> -
<select name="a"> -
<option value="男">男</option> -
<option value="女">女</option> -
</select> -
</td> -
<td> -
<input type="text" name="b"> -
</td> -
<td> -
<input type="text" name="c"> -
</td> -
</tr> -
</table> -
<input type="button" name="Submit2" value="添加" onclick="addRow()"> -
<script> -
function addRow(){ -
//添加行 -
var newTr = testTbl.insertRow(); -
//添加列 -
var newTd0 = newTr.insertCell(); -
var newTd1 = newTr.insertCell(); -
var newTd2 = newTr.insertCell(); -
var newTd3 = newTr.insertCell(); -
//设置列内容和属性 -
newTd0.innerText = document.all("a").options[document.all("a").selectedIndex].text; -
newTd1.innerText = document.all("b").value; -
newTd2.innerText = document.all("c").value; -
newTd3.innerHTML= '<input type="button" name="del" value="删除" onclick="del(this)">'; -
} -
function del(o){ -
//获取表格 -
var t=document.getElementById('testTbl'); -
//删除当前行 -
t.deleteRow(o.parentNode.parentNode.rowIndex) -
} -
</script> -
</body> -
</html>
-
//动态添加行 -
function addRow(){ -
var table = document.getElementById("tableID"); -
var newRow = table.insertRow(); //创建新行 -
var newCell1 = newRow.insertCell(); //创建新单元格 -
newCell.innerHTML = ""； //单元格内的内容 -
newCell.setAttribute("align","center"); //设置位置 -
} -
//动态删除行 -
function deleteRow(){ -
var rowIndex = event.srcElement.parentElement.parentElement.rowIndex; -
var styles = document.getElementById("tableID"); -
styles.deleteRow(rowIndex); -
}
用克隆的方式
-
<html> -
<head> -
<script type="text/javascript" src="jquery-easyui/jquery.min.js"></script> -
<script type="text/javascript"> -
var index = 0; -
$(document).ready(function(){ -
$("button").click(function(){ -
index++; -
$("body").append($("p").clone().attr({'id':'name'+index,'name':'pwd'+index})); -
}); -
}); -
</script> -
</head> -
<body> -
<p>This is a paragraph.</p> -
<button>复制每个 p 元素，然后追加到 body 元素</button> -
</body> -
</html>
下面是直接添加和删除当前table表格,很好用
