input (type="submit") | NN 2 IE 3 DOM 1
The submit object is a form control generated with an input element that has a type attribute set to "submit". This object is similar to the button object, but a submit object has more implied power. No script action is necessary for the submit object to do its job of submitting the containing form to the server. If you require a button to perform a script action, but not an actual form submission, use the button or button-type input object instead. Otherwise, the submit object automatically reloads the current document (i.e., obeying the form's default action, which is the page's URL), perhaps destroying important script variables. To initiate form validation, use the onsubmit event handler of the form object rather than the onclick event handler of the submit button. If the event handler evaluates to true, the form is submitted; if it evaluates to false, the submission is cancelled. The scripted equivalent of a submit-type input object is the form object's submit( ) method.

form | NN 2 IE 3 DOM 1
| Read-only
Returns a reference to the form element that contains the current element. When processing an event from this element, the event handler function automatically has access to the input element (as the event object's target or srcElement property). By reading the form property, the script can easily access other controls within the same form.
Example
    var theForm = evt.srcElement.form;
Value
form element object reference.
Default
None.

name | NN 2 IE 3 DOM 1
| Read/Write
This is the identifier associated with the form control. Names are hidden from user view, since control labels are assigned via other means, depending on the control type. Form control names may also be used by script references to the objects.
Example
    document.orderForm.mySubmit.name = "sender";
Value
Case-sensitive string identifier that follows the rules of identifier naming: it may contain no whitespace, cannot begin with a numeral, and should avoid punctuation except for the underscore character.
Default
None.

type | NN 3 IE 4 DOM 1
| Read-only
Returns the type of form control element. The value is returned in lowercase letters. You may have to cycle through all form elements in search of specific types to do some processing on (e.g., emptying all form controls of type "text", leaving other controls untouched).
Example
    if (document.forms[0].elements[3].type == "submit") {
        // process submit input type here
    }
Value
Any of the following constants (as a string): button | checkbox | file | hidden | image | password | radio | reset | select-multiple | select-one | submit | text | textarea.
Default
submit

value | NN 2 IE 3 DOM 1
| Read/Write
This is one of the rare times that the value property controls the label of a form control: the text that appears on the submit button.
Example
    document.forms[0].mySubmit.value = "Send";
Value
String.
Default
Submit

createTextRange( ) | NN n/a IE 4(Win) DOM n/a
Creates a TextRange object containing the button's label text. See the TextRange object for details.
Parameters
None.
Returned Value
TextRange object.

handleEvent[ ] | NN |4| IE n/a DOM n/a
handleEvent(event) |
Instructs the object to accept and process the event whose specifications are passed as the parameter to the method. The object must have an event handler for the event type to process the event. Navigator 4 only
Parameters
A Navigator 4 event object.
Returned Value
None.
