Suppose, I have following HTML code :

<button>Click Me!</button>

In above code I have not used the attribute 'type'.

So, in this case will this button behave like a Submit Button which will submit all the form data to the server?

If yes, then can I execute JavaScript code on the onclick event of above button which is missing the 'type' attribute?

If no, what exactly will happen?

Thanks.

If you want a button to behave like just a button, then yes, your markup needs to be:

<button type="button">Click Me!</button>

In this case, you can easily add a click event with:

document.getElementsByTagName('button')[0].addEventListener('click',myFunction,false);

---

N.B. If you don't mark up the button properly (ie. you omit the type attribute) and the browser then treats it like a input type="submit", you can still add a submit event:

document.getElementsByTagName('button')[0].addEventListener('submit',myFunction,false);

Yes, the default type for button is submit; as is documented in the spec.

Yes, it will.

If yes, then can I execute JavaScript code on the onclick event of above button which is missing the 'type' attribute?

Yes, of course you can, just like any other button. The click handler will run before the form is submitted.
