How to implement the function of adding attachments in javascript_javascript skills
We often use adding attachments in emails, now we can simply apply it:
Rendering:
Implementation principle:
The main idea of using table tags: using table tags
1. After clicking on the text, it will be automatically created (originally it was created by yourself/, now after getting the table object, you can insertRow() insertCell()) to create rows and columns
2. When deleting, remove it through the parent node
Core code:
function creatMail(){
var tab=document.getElementById("tabid");
var tr=tab.insertRow();//插入一行
var td=tr.insertCell();//插入一列
var td2=tr.insertCell();//插入一列
td.innerHTML="<input type='file' value='选择文件'/> ";
/*
td2.innerHTML="<a href='javascript:void(0)' onclick='Delrows(this)'>删除</a>";
*/
td2.innerHTML="<img src='11.jpg' alt='删除' onclick='Delrows(this)'>";
} The entire code is as follows (tips: just add it)
<!DOCTYPE html>
<html>
<head>
<!--主要思想：采用table标签方式
1,点击文字之后，就自动创建（原先是自己/创建，现在拿到table对象之后，可以insertRow() insertCell()）创建行和列
2，删除的时候通过父节点来移除
-->
<title>AddMail.html</title>
<link rel="stylesheet" type="text/css" href="1.css">
<script type="text/javascript">
function creatMail(){
var tab=document.getElementById("tabid");
var tr=tab.insertRow();//插入一行
var td=tr.insertCell();//插入一列
var td2=tr.insertCell();//插入一列
td.innerHTML="<input type='file' value='选择文件'/> ";
/*
td2.innerHTML="<a href='javascript:void(0)' onclick='Delrows(this)'>删除</a>";
*/
td2.innerHTML="<img src='11.jpg' alt='删除' onclick='Delrows(this)'>";
}
function Delrows(node){//当前对象是<a>里面
var tr=node.parentNode.parentNode;//tr对象
tr.parentNode.removeChild(tr);//tr的父对象table移除子节点
}
</script>
</head>
<body>
<table id="tabid">
<tr>
<td><a href="javascript:void(0)" onclick="creatMail()">添加附件</a></td>
</tr>
</table>
</body>
</html> The above is the entire content of this article. It shares the implementation principle, core code, and everyone’s favorite JavaScript code to implement the attachment function. I hope it will be helpful to everyone’s learning.

Demystifying JavaScript: What It Does and Why It Matters
Apr 09, 2025 am 12:07 AM
JavaScript is the cornerstone of modern web development, and its main functions include event-driven programming, dynamic content generation and asynchronous programming. 1) Event-driven programming allows web pages to change dynamically according to user operations. 2) Dynamic content generation allows page content to be adjusted according to conditions. 3) Asynchronous programming ensures that the user interface is not blocked. JavaScript is widely used in web interaction, single-page application and server-side development, greatly improving the flexibility of user experience and cross-platform development.
