input type="submit" Vs button tag are they interchangeable? [duplicate]

input type="submit" and button tag are they interchangeable? or if there is any difference then When to use input type="submit" and when button ?

And if there is no difference then why we have 2 tags for same purpose?

Solution 1:

http://www.w3.org/TR/html4/interact/forms.html#h-17.5

Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content. For example, a BUTTON element that contains an image functions like and may resemble an INPUT element whose type is set to "image", but the BUTTON element type allows content.

So for functionality only they're interchangeable!

(Don't forget, type="submit" is the default with button, so leave it off!)

Solution 2:

The <input type="button"> is just a button and won't do anything by itself. The <input type="submit">, when inside a form element, will submit the form when clicked.

Another useful 'special' button is the <input type="reset"> that will clear the form.

Solution 3:

Although both elements deliver functionally the same result *, I strongly recommend you use <button>:

• Far more explicit and readable. input suggests that the control is editable, or can be edited by the user; button is far more explicit in terms of the purpose it serves
• Easier to style in CSS; as mentioned above, FIrefox and IE have quirks in which input[type="submit"] do not display correctly in some cases
• Predictable requests: IE has verying behaviours when values are submitted in the POST/GET request to the server
• Markup-friendly; you can nest items, for example, icons, inside the button.
• HTML5, forward-thinking; as developers, it is our responsibility to adopt to the new spec once it is officialized. HTML5, as of right now, has been official for over one year now, and has been shown in many cases to boost SEO.

* _{With the exception of <button type="button"> which by default has no specified behaviour.}

In summary, I highly discourage use of <input type="submit"/>.

Solution 4:

Use <button> tag instead of <input type="button"..>. It is the advised practice in bootstrap 3.

"Cross-browser rendering

As a best practice, we highly recommend using the <button> element whenever possible to ensure matching cross-browser rendering.

Among other things, there's a Firefox bug that prevents us from setting the line-height of <input>-based buttons, causing them to not exactly match the height of other buttons on Firefox."

Solution 5:

<input type='submit' /> doesn't support HTML inside of it, since it's a single self-closing tag. <button>, on the other hand, supports HTML, images, etc. inside because it's a tag pair: <button><img src='myimage.gif' /></button>. <button> is also more flexible when it comes to CSS styling.

The disadvantage of <button> is that it's not fully supported by older browsers. IE6/7, for example, don't display it correctly.

Unless you have some specific reason, it's probably best to stick to <input type='submit' />.
