188544 - A BUTTON tag that calls a javascript function via the onClick event also submits the form

Status: VERIFIED DUPLICATE of bug 97829

(Core :: JavaScript Engine, defect)

Description

[Jeremy Adams]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021212
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.3a) Gecko/20021212

<BUTTON onClick="addrow()">Add Row</BUTTON> will actually submit the form on the
webpage, even though there's nothing in the javascript function that tells it to
do so. The addrow function is suppose to simply move information that's in a
text input box into a select input box. This works as expected in IE, but not in
any version of Mozilla that I've tried (starting with 1.0.1 up through 1.3a).


Reproducible: Always

Steps to Reproduce:
1. Click the AddRow button

Actual Results:  
The form submits, even though it's not suppose to.

Expected Results:  
Run the javascript and NOT submit the form on the page.

Where is a bug? Look here: http://www.w3.org/TR/html401/interact/forms.html#h-17.5

type = submit|button|reset [CI]
    This attribute declares the type of the button. Possible values:
        * submit: Creates a submit button. This is the default value.

So if you use button without specific type it should do a submit. IE is broken
in this case.

Attachment: default button type is submit

Comment 3

This is a bug in IE.  A <button> with no type set is a submit button.

Verified Duplicate -

Note this is not a JavaScript Engine issue. JavaScript Engine deals
with the abstract JavaScript programming language. Specifically, the
low-level objects such as String(), Number(), and Date(). The JS Engine
does not contain browser or DOM objects like document, forms, etc.

The best component for this would have been Form Submission 
(as in bug 97829).
