本文实例讲述了JS/jQuery实现超简单的Table表格添加,删除行功能。分享给大家供大家参考,具体如下:

最近需要表格添加删除行,添加行简单,删除行就有点儿懵逼了,于是网上找实例,功夫不负有心人,终于让我找到了,下面的是代码,大家觉得可以,记得点赞哦!!!谢谢!

需要的拿去,转载请在明显的位置标注出出处!!!

<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" οnclick="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 src="http://libs.baidu.com/jquery/2.0.0/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
