You can disable paste in your input as follows:
您可以按如下方式在输入中禁用粘贴：
html:
html：
<input type="text" value="" id="myInput">
javascript:
javascript:
window.onload = function() {
const myInput = document.getElementById('myInput');
myInput.onpaste = function(e) {
e.preventDefault();
}
}
Talking about security, I wouldn't say that this makes any impact. You would usually use client side and well as server-side validation of data submitted by the user.
谈到安全性，我不会说这会产生任何影响。您通常会使用客户端和服务器端验证用户提交的数据。
