Here is my code for making POST request:
function post(path, params, method) {
method = method || "post"; // Set method to post by default if not specified.
// The rest of this code assumes you are not using a library.
// It can be made less wordy if you use one.
var form = document.createElement("form");
form.setAttribute("method", method);
form.setAttribute("action", path);
form.setAttribute("enctype", "application/json");
for(var key in params) {
if(params.hasOwnProperty(key)) {
var hiddenField = document.createElement("input");
hiddenField.setAttribute("type", "hidden");
hiddenField.setAttribute("name", key);
hiddenField.setAttribute("value", params[key]);
form.appendChild(hiddenField);
}
}
document.body.appendChild(form);
form.submit();
}
I tried to set the Content-type
in HTTP header to "application/json" by setting enctype
of the form to "application/json". However, it doesn't work.
I saw an unofficial draft about supporting "application/json" for enctype
however it seems not accepted yet..
Does anyone have ideas about how to make a POST request and use JSON
instead of formdata
as the data format without resorting to AJAX?
