I am currently facing some order duplication issues. Without going into too much detail, I had a question about the following. Is there any possibility that this can trigger a submit twice?

<button type="submit" onclick="review.save()"></button>

review.save() will handle the submission of the form - so in fact the type=submit isn't needed here. But I want to establish whether this CAN cause the browser to submit twice. On the server logs the 2 submits were about 10 seconds apart.

• javascript
• html
• forms
• button
• submit

• The browser does not submit twiche. It submits, when the button is clicked. What your function call review.save() does is on another page... ;) – I'm with Monica Commented Nov 5, 2013 at 12:37
• Impatient users clicking twice maybe? Its a good idea to disable the button so as the users cannot click twice. – Fred Commented Nov 5, 2013 at 12:37

You need to prevent default browser behaviour, for example:

<button type="submit" onclick="review.save(); return false;"></button>

Add a return false to your Button or better the 'oncklick' event!

Like:

<button type="submit" onclick="review.save();return false;"></button>

It "stops" the default browser behaviour of following links (in that case).

Edit: To slow :/
