Difference between <input type='button' /> and <input type='submit' />
(4 answers)
Closed 1 year ago.
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?

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!)
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.
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"/>.
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."
<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' />.
I realize this is an old question but I found this on mozilla.org and think it applies.
A button can be of three types: submit, reset, or button. A click on a
submit button sends the form's data to the web page defined by the
action attribute of the element. A click on a reset button
resets all the form widgets to their default value immediately. From a
UX point of view, this is considered bad practice. A click on a button
button does... nothing! That sounds silly, but it's amazingly useful
to build custom buttons with JavaScript.

<button> is newer than <input type="submit">, is more semantic, easy to stylize and support HTML inside of it.
While the other answers are great and answer the question there is one thing to consider when using input type="submit" and button. With an input type="submit" you cannot use a CSS pseudo element on the input but you can for a button!
This is one reason to use a button element over an input when it comes to styling.
I don't know if this is a bug or a feature, but there is very important (for some cases at least) difference I found: <input type="submit"> creates key value pair in your request and <button type="submit"> doesn't. Tested in Chrome and Safari.
So when you have multiple submit buttons in your form and want to know which one was clicked - do not use button, use input type="submit" instead.
If you are talking about <input type=button>, it won't automatically submit the form
if you are talking about the <button> tag, that's newer and doesn't automatically submit in all browsers.
Bottom line, if you want the form to submit on click in all browsers, use <input type="submit">

Something like this:
Where the user would click on any area of the button and it would select that radio button.
Any suggestions?
As far as I can tell, radio buttons as self closed, and can't wrap around other elements.
The best way is to just wrap the <input> in its <label>, as clicking a label also has the effect of focusing its associated input:
<label>
<input name="transfer" type="radio">Bank Deposit
</label>
No javascript required: Demo: http://jsfiddle.net/GTGan/
If you need to style the label text separately, just wrap it in a <span>.
use Bootstrap, to create buttons around radiobuttons:
<label class="btn btn-lg btn-default">
<input type="radio"> Something
</label>
Have you tried using the LABEL tag? For accessibility sake we should be using label tags to associate labels to form controls all of the time. Not only does that help tie things together for screen readers, but it also makes the label as well as the control clickable.
You can read a bit more detail and find an example here:
http://webaim.org/techniques/forms/screen_reader#labels
You could use javascript for achieving this effect by giving it an onClick event, or you could just use jQuery in combination with some gui-plugins. I'd prefer this solution for cross-browser compatibility.
There are many legends about them. I want to know the truth. What are the differences between the two following examples?
<input type='submit' value='text' />
<button type='submit'>text</button>
Not sure where you get your legends from but:
Submit button with <button>
As with:
<button type="submit">(html content)</button>
IE6 will submit all text for this button between the tags, other browsers will only submit the value. Using <button> gives you more layout freedom over the design of the button. In all its intents and purposes, it seemed excellent at first, but various browser quirks make it hard to use at times.
In your example, IE6 will send text to the server, while most other browsers will send nothing. To make it cross-browser compatible, use <button type="submit" value="text">text</button>. Better yet: don't use the value, because if you add HTML it becomes rather tricky what is received on server side. Instead, if you must send an extra value, use a hidden field.
Button with <input>
As with:
<input type="button" />
By default, this does next to nothing. It will not even submit your form. You can only place text on the button and give it a size and a border by means of CSS. Its original (and current) intent was to execute a script without the need to submit the form to the server.
Normal submit button with <input>
As with:
<input type="submit" />
Like the former, but actually submits the surrounding form.
Image submit button with <input>
As with:
<input type="image" />
Like the former (submit), it will also submit a form, but you can use any image. This used to be the preferred way to use images as buttons when a form needed submitting. For more control, <button> is now used. This can also be used for server side image maps but that's a rarity these days. When you use the usemap-attribute and (with or without that attribute), the browser will send the mouse-pointer X/Y coordinates to the server (more precisely, the mouse-pointer location inside the button of the moment you click it). If you just ignore these extras, it is nothing more than a submit button disguised as an image.
There are some subtle differences between browsers, but all will submit the value-attribute, except for the <button> tag as explained above.
With <button>, you can use img tags, etc. where text is
<button type='submit'> text -- can be img etc. </button>
with <input> type, you are limited to text
In summary :
<input type="submit">
<button type="submit"> Submit </button>
Both by default will visually draw a button that performs the same action (submit the form).
However, it is recommended to use <button type="submit"> because it has better semantics, better ARIA support and it is easier to style.
I have an html form and the submit button says "submit query". How can I remove this text? I am using a background image for the submit button and this text is messing up the button :( Any help would be greatly appreciated.
If you do not give your submit button a value
<input type="submit" />
instead of something like
<input type="submit" value="Submit" />
it will display 'submit query' by default. Try giving it a space as the value.
use:
<input type='submit' name='btnTest2' value=''>
Leave the value blank and there will be no words on the button. Since you're using a background image a for the button, give the button a height and width, otherwise it will display as a small gray blip (because there are no words on the button).
Background images are not content. If you want to use an image to tell people what a submit button will do, use a real image. As a bonus that allows you to provide alternative text for users who cannot see the image (e.g. because it failed to load or because they are blind).
<button type="submit">
<img src="example.png" alt="Submit">
</button>
Just use the value attribute as shown below:
<input value="Whateveryouwant" type="submit">
You just have to give it a value:
<input type='submit' name='btnTest'>
<input type='submit' name='btnTest2' value='Push Me'>
In the example above, btnTest renders as "Submit Query" while btnTest2 renders as "Push Me". Hope this helps.
UPDATE: You can do this to not display any text.
<input type='submit' name='btnTest2' value='' style="width:100px;">
Not sure if this was relevant then, but we would use type="image" rather than type="submit"
Just put a space between the value quotes. Simple fix.
Read the question before you reply. You may actually help someone.
Unfortunately, this does not work, at least not in a CMS. I've tried the space and the but IE8 will not recognize it. If I put the same in the value, it reverts back to 'Submit Query'. Just updating for anyone else who finds this method through a search.
EDIT : I added text indent: -9999px; to my CSS, and it seems that it worked. I still added the space in the value attribute for good measure.
I had this issue as well. If you don't set a value for a submit button it defaults to "Submit Query". I assume you are using an image for your submit button since you have the default value.
If you want to fix it for IE8 add a text indent using CSS which will push the default value off the screen.
text-indent:9999px;
If you want to fix it for IE9 you also need to change the default value because the text-indent doesn't work :( in your submit button add the following:
value=" "
I found this to work without a non-breaking space and tested it to my satisfaction on the IE's on browserstack. If you want to use the breaking space, feel free; I'll include the code.
value=" "
Also, thank you to the other stack-responders, you helped me fix this issue on IE9.
Also you inspired me to post my findings here and possibly help others!
If you are using something like a jQueryUI dialog button then you do not want to have the input button show up in the form, but rather just have it in the footer of the dialog. I accomplished this by doing the following:
Because IE will automatically put in an <input type="submit" /> I put this in the form instead: <input type="submit" style="display:none" />
Then later in the dialog JavaScript I put:
$("#register-dialog").dialog({
title: "Register",
modal: true,
width: 700,
buttons: {
Register: function () {
$('#registrationForm').submit();
},
Close: function () {
$(this).dialog("close");
}
}
});
Just remove the text with jQuery?
jQuery:
$('#btnSubmit').val('');
Plus the solutions mentioned with HTML and jQuery, you can put
font-size: 0px;
for the input and it wouldn't show the text anymore.
This worked in my case.
that's it browser show default use this
value="submit" is important
use attribute value="submit"
nothing just do this
<input type="submit /"
a slash with a space and u will not see the Submit or Submit Query no need to give value
