192163 - Button HTML tag submits the form even if the onclick event is history.back instead of form.submit

Status: RESOLVED DUPLICATE of bug 97829

(Core :: DOM: Core & HTML, defect)

Description

[Jon Trelfa]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1) Gecko/20021130
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2.1) Gecko/20021130

I created a form that has a "preview" feature.  The first time the form is
submitted, the data entered is displayed on the next page.  At the end of this
second, "preview" form, there is an <input type="submit"> button and a <button
onclick="history.back()">  button.  When I click on the <button> button, it
actually submits the form rather than going back one page in the javascript history.

Reproducible: Always

Steps to Reproduce:
1. Create a form and submit it to a "preview" script.
2. Using your favorite CGI (I used PHP), process the form only enough to show
the data that was entered into the first form.
3. In the processed form display the results of the form and enter the data into
"hidden" form fields.
4.  within the <form></form> tags, put a <button> tag like this:
<button onClick="history.back();">Go Back and Edit</button>
5.  Click the button and the form will actually be submitted rather than go back.
Actual Results:  
The "preview" form was submitted rather than performing the "onclick" command.

Expected Results:  
It should have performed the javascript command to go back 1 page rather than
submitting the form.

THis one is 100% dupe of bug 188544 (button click also submit form), wich marked
as dupe of bug 97829. So I propose dupe to bug 97829.

I apologize for this dupe.  I searched the bug database and it didn't show up,
so I posted it.  Please forgive the trouble.
