new FormData() “application/x-www-form-urlencoded”

Question

Couchdb only parse application/x-www-form-urlencoded. Is there a FormData() attribute that set the enctype?

xhr.open(\'put\',document.myForm.action,false)
xh         


        

Answer 1

Some time ago I wrote the following function. It collects form values and encodes them url encoded, so they can be sent with content type application/x-www-form-urlencoded:

function getURLencodedForm(form)
{
  var urlEncode = function(data, rfc3986)
  {
    if (typeof rfc3986 === 'undefined') {
      rfc3986 = true;
    }

    // Encode value
    data = encodeURIComponent(data);
    data = data.replace(/%20/g, '+');

    // RFC 3986 compatibility
    if (rfc3986)
    {
      data = data.replace(/[!'()*]/g, function(c) {
        return '%' + c.charCodeAt(0).toString(16);
      });
    }

    return data;
  };

  if (typeof form === 'string') {
    form = document.getElementById(form);
  }

  var url = [];
  for (var i=0; i < form.elements.length; ++i)
  {
    if (form.elements[i].name != '')
    {
      url.push(urlEncode(form.elements[i].name) + '=' + urlEncode(form.elements[i].value));
    }
  }

  return url.join('&');
}

// Example (you can test & execute this here on this page on stackoverflow)
var url = getURLencodedForm('post-form');
alert(url);
