Can I assign a form to a variable?

So if I have a form called myForm and a field called myField, I know I can access that field by using:

document.myForm.myField.value

Is there a way to assign the form itself to a variable like:

var f = document.myForm

so that I can access the fields by just using: f.myField.value in order to save myself some typing?

I tried it and it didn't work so I don't know if it's not possible or if I'm just doing something wrong.

Yeah of course you can do it! Just add a variable like var act_form = document.forms["myform"]; //make use of it var action =act_form.action, method = act_form.method; alert(method);

and in the form contains <form name="myform" method="post" action="example.com"></form>

Yes.

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body>
  <form id="example">
    <input name="field" value="default value">
  </form>
  <script>
    var frm = document.forms.example;
    alert(frm.elements.field.value);
  </script>
</body>
</html>
