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.
