If your backend language is PHP, look for $_SERVER['HTTP_REFERER'].如果您的后端语言是 PHP，请查找 $_SERVER['HTTP_REFERER']。 Other backend languages also have similar Referrer global variables.其他后端语言也有类似的 Referrer 全局变量。

You can add submit event to your form , it will be executed shortly before submit action.您可以在form中添加submit事件，它将在提交操作之前不久执行。 And set value of hidden field.并设置隐藏字段的值。
let myForm = document.getElementById('form'); myForm.addEventListener('submit', function(){ let myForm = document.getElementById('url').value = location.href; })
<html> <body> <form id="form" action="" method="post"> <input type="hidden" name="html" id="url"> <input type="submit"> </form> </body> <html>
