This time I will bring you JQuery to implement the form function that can be edited in real time. What are the precautions for JQuery to implement the form function that can be edited in real time. The following is a practical case, let's take a look. The final effect we want to achieve is as follows:

When you click the student number column, you can edit it:

When ESC is clicked, the operation is canceled. When Enter is clicked, the modification takes effect (no interaction with the background)
The page code is as follows (asp.net):

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="EditTable.aspx.cs" Inherits="EditTable" %> 
 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head runat="server"> 
 <title></title> 
 <link href="css/eidtTable.css" rel="stylesheet" type="text/css" /> 
 <script src="js/jquery-1.9.1.min.js" type="text/javascript"></script> 
 <script src="js/eidtTable.js" type="text/javascript"></script> 
</head> 
<body> 
 <form id="form1" runat="server"> 
 <p> 
 <table> 
 <thead> 
 <tr> 
  <th colspan="2">可编辑的表格</th> 
 </tr> 
 </thead> 
 <tbody> 
 <tr> 
  <th>学号</th> 
  <th>姓名</th> 
 </tr> 
 <tr> 
  <td class="editTd">00001</td> 
  <td>小明</td> 
 </tr> 
 <tr> 
  <td class="editTd">00001</td> 
  <td>小明</td> 
 </tr> 
 <tr> 
  <td class="editTd">00001</td> 
  <td>小明</td> 
 </tr> 
 <tr> 
  <td class="editTd">00001</td> 
  <td>小明</td> 
 </tr> 
 </tbody> 
 </table> 
 </p> 
 </form> 
</body> 
</html>

CSS (eidtTable.css)

table 
{ 
 border:1px solid black; 
 border-collapse:collapse; 
 width:500px; 
 } 
table th 
{ 
 border:1px solid black; 
 width:50%; 
 } 
table td 
{ 
 border:1px solid black; 
 width:50px; 
 } 
tbody th 
{ 
 background-color:#A3BAE9 
 }

JS(eidtTable.js):

/// <reference path="jquery-1.9.1.min.js" /> 
 
//$(document).ready(function () { 
// alert('test'); 
//}); 
 
//简便的写法 
$(function () { 
 $("tr:odd").css("background-color", "#ECE9D8"); 
 var objTd = $(".editTd"); 
 
 objTd.click(function () { 
 var text = $(this).html(); 
 var objThisTd = $(this); 
 
 //解决点击文本框和td中间的空隙还是会出问题 这个问题 
 if (objThisTd.children("input").length > 0) { 
 return false; 
 } 
 
 var inputText = $("<input value=&#39;test&#39; type=&#39;text&#39;/>"); 
 
 inputText.width(objTd.width()).css("font-size", "16px").css("background-color", objTd.css("background-color")).css("border-width", "0").val(text); 
 
 objThisTd.html(""); 
 inputText.appendTo(objThisTd); 
 
 inputText.trigger("focus").trigger("select"); 
 
 inputText.click(function () { 
 return false; 
 }); 
 
 //这里采用的keydown事件，我试过用keyup事件无法屏蔽浏览器的回车页面提交事件 
 inputText.keydown(function (event) { 
 //alert(event.keyCode); 
 var keycode = event.which; 
 if (keycode == 13) { 
 objThisTd.html($(this).val()); 
 //return false; 
 } 
 if (keycode == 27) { 
 objThisTd.html(text); 
 } 
 }); 
 }); 
});
