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 border=1> <tr> <td>性别</td> <td>姓名</td> <td>年龄</td> </tr> <tr> <td> <select> <option value="男">男</option> <option value="女">女</option> </select> </td> <td> <input type="text"> </td> <td> <input type="text"> </td> </tr> </table> <input type="button" value="添加"> <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" 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="https://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
