What is the best way to transmit information using the POST method in JavaScript?

When using javascript, the typical way to redirect a page with a parameter is the following:

window.location = "add-new-cos.jsp?id="+id;

However, the id value is sent to the next page using the GET method. I am interested in sending it using the POST method instead. Is there a way to achieve this using javascript?

Answer №1

While not as simple as using a window.location redirect, this method is still relatively straightforward :)

let newForm = document.createElement("form");
    let newInput = document.createElement("input");

newForm.action = "add-new-cos.jsp";
newForm.method = "post"

newInput.type = "hidden";
newInput.name = "id";
newInput.value = id;
newForm.appendChild(newInput);

document.body.appendChild(newForm);
newForm.submit();

Answer №2

To send POST data, you have two options: submitting a form or using an ajax request. A possible solution is to generate an invisible form with hidden fields containing the necessary names and values, and then use JavaScript to submit it when required.

Answer №3

To include the identifier in a form, employ the JavaScript command

document.forms["myform"].submit();
, then utilize a redirect action within your server's request handler.

Answer №4

Unfortunately, using window.location.href does not support sending a POST request.

To accomplish this task, you need to create a form element with data fields included, set the action attribute of the form to the desired URL, specify the method attribute as POST, and finally trigger the submit method on the form itself.
