本文實例講述了JS/jQuery實現超簡單的Table表格添加,刪除行功能。分享給大家供大家參考，具體如下：
最近需要表格添加刪除行,添加行簡單,刪除行就有點兒懵逼了,于是網上找實例,功夫不負有心人,終于讓我找到了,下面的是代碼,大家覺得可以,記得點贊哦!!!謝謝!
需要的拿去,轉載請在明顯的位置標注出出處!!!
<html><head> <title>table添加/刪除行</title></head><body><table id="testTbl" border=1> <tr> <td>性別</td> <td>姓名</td> <td>年齡</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(); //設置列內容和屬性 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="刪除" οnclick="del(this)">';}function del(o){ //獲取表格 var t=document.getElementById('testTbl'); //刪除當前行 t.deleteRow(o.parentNode.parentNode.rowIndex)}</script></body></html>//動態添加行function addRow(){ var table = document.getElementById("tableID"); var newRow = table.insertRow(); //創建新行 var newCell1 = newRow.insertCell(); //創建新單元格 newCell.innerHTML = ""； //單元格內的內容 newCell.setAttribute("align","center"); //設置位置}//動態刪除行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>復制每個 p 元素，然后追加到 body 元素</button></body></html>下面是直接添加和刪除當前table表格,很好用
