Every form field is contained in the form's elements collection.

You can access the various fields in the collection by using their name attributes or their positions in the collection:

var firstField = oForm.elements[0];    //get the first form field
var myTextbox = oForm.elements["textbox1"];//get the field with the name "textbox1"

Accessing an element by its name: every form field becomes a property of the form itself and can be accessed directly by using its name

var myTextbox1 = oForm.textbox1; //get the field with the name "textbox1"

If the name has a space in it, use bracket notation instead:

var myTextbox = oForm["text box 1"]; //get the field with the name "text box 1"
