How to get the form page url?-CodePudding

I want to get the live URL from which an HTML form has been submitted. Like a hidden input tag using a javascript function, which will send me the URL with the form submission. How can I do that?

CodePudding user response：

If your backend language is PHP, look for $_SERVER['HTTP_REFERER']. Other backend languages also have similar Referrer global variables.

You can add submit event to your form, it will be executed shortly before submit action. And set value of hidden field.

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>
