Ive been having great frustration for hours now trying to remember my AJAX!

我现在一直在努力记住我的AJAX，感到非常沮丧！

Im trying to write a function which will be called that will simply POST 4 variables to a given URL, written in javascript and not jquery such as:

我试图编写一个将被调用的函数，只需将4个变量POST到给定的URL，用javascript编写而不是jquery，例如：

function postVariables(URL, var1, var2, var3, var4)
{
  ......
  return true;
}

Can anyone help?

有人可以帮忙吗？

Been a while since I've done this without jQuery but something like

已经有一段时间了，因为我没有jQuery这样做，但有点像

function postVariables(URL, var1, var2, var3, var4)
{
  var xhr= new XMLHttpRequest();

  var postvars = "var1=" + var1 + "&var2=" + var2 etc;
  xhr.open("POST", URL, true);

  xhr.setRequestHeader("Content-type", "text/html;");
  xhr.setRequestHeader("Content-length", postvars.length);
  xhr.setRequestHeader("Connection", "close");

  xhr.send(postvars);
}

I'm sure my syntax is off somewhere or other, but you should be able to search for XmlHttpRequest and find some valid samples.

我确定我的语法在某处或其他地方，但你应该能够搜索XmlHttpRequest并找到一些有效的样本。
