<form action="/foo">
<input type="text" name="q">
<input type="submit" >
</form>
In the previous HTML, if the user types in 'bar' and clicks the button it would submit to example.com/foo?q=bar.
How can I make it go to example.com/foo/bar?
I can easily do it with JS but I'm trying to stick to HTML.
There is no way to do this in HTML, you need a programming language.
Have something on the server process the form an issue an HTTP 301 response with a Location header.
You could enhance that by use the form's submit event to prevent the default action and set location in JS.
You cannot change the value of the action attribute with HTML only. You need to use JS or any other scripting language.

My form is like this:
<form method="GET" action="target">
<input type="text" name="filter"/>
<select name="skill">
<option>opt1</option>
<option>opt2</option>
<option>opt3</option>
</select>
<input type="number" name="level"/>
<input type="submit"/>
</form>
I would like the empty parameters not to be shown in the URL when the form is submitted, and this happens with the skill field , but not with level and filter, which are added to the Query string even though they're empty. How does it happen? Is it possible to prevent this from happening without using javascript?
None of these fields is required to submit the form.
This is not possible without javascript.
You can use something like jQuery to accomplish this.
note: Using form method POST is the preferred way of submitting forms, and the parameters are submitted as http request body and not in the URL.
If you do a form POST instead of GET, the form params will not appears in the query string. But that would require back end changes.
So I have this form and I really want to use html5 validation. Problem is, there are two things my form needs to do:
Simply save the current state so it can be reloaded later (via jsp/servlets) (WITHOUT VALIDATING)
Actually submit the form (validate it before submitting)
Is there a way to turn off validation for a given button/submit but keep it for the other?
My workaround would be to use an AJAX call for the former and regular submit for the latter, but it kind of messes up the system I have in place.
You can add the "novalidate" attribute when the user clicks on a given button.
<form method="post" action="/foo" novalidate>...</form>
This disables html validation.
Add it again when you want your final submission.
EDIT
Apparently there's a better option, the formnovalidate attribute, that you can add to a specific field (which apparently is exactly what you want):
<form action="demo_form.asp">
E-mail: <input type="email" name="userid"><br>
<input type="submit" value="Submit"><br>
<input type="submit" formnovalidate="formnovalidate" value="Submit without validation">
</form>
Yes, by toggling the novalidate attribute (or the noValidate property on the HTMLFormElement object) with JavaScript.

I have a button that is this <button id="btnSubmit">Submit</button> the problem is, I want the form tags to use this id so that is designed the way I want. And also this code, I have a few questions.
<form action="demo_form.php" method="get">
First name: <input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br>
<input type="submit" value="Submit">
</form>
what is the action="demo_form.php",input type="submit" do? And does the input type has any other "What do you call this stuff" besides submit?
The action="demo_form.php" sets the action, in this case, "navigate to file demo_form.php and send it the data".
<input type="submit" (...) > creates and element which submits the form e.g. executes the "action".
The method sets the way the data is submitted to the target of the action ("form_demo.php"), in this case get, which allows you to refer to the submitted data as $GET["name"] in PHP.
Possible input types are listed here.
You either give your <input type="submit" (...) > the id="btnSubmit" property or use javascript to submit the form after an event has been triggered.
MOr info on that is available here (i short: document.<get_the_form_element>.submit();).
I suggest you to take a look at this link. It describes all the basic concepts about how using forms. And you can also find a lot of information by Googling it.
The action attribute
The action attribute defines the action to be performed when the form is submitted.
The common way to submit a form to a server, is by using a submit button.
The input attribute
<input type="submit"> defines a button for submitting a form to a form-handler.
The form-handler is typically a server page with a script for processing input data.
If i understand your question correctly, these are my answers.
action
The action attribute describes the page to which the contents of the form are sent to. So if you have a sign up form with an input for an email, the text that is typed will be sent to the action path. It will be sent using the method described in the method attribute. So you can find your values in either the $_POST variable, or the $_GET variable, get is easy for being able to share the url and post is great for private information.
input
The input element is the actual way to input information (who guessed it). You've got an input of the type text for just text input, you've got checkbox for a true or false input and way way more see: w3schools
why don't you use
<input type="submit" value="Submit" id="btnSubmit">
Or if you want to use a button
<button id="btnSubmit">Submit</button>
Then from jquery or js you can submit the form.
And for this question,
what is the action="demo_form.php",input type="submit" do?
You should probably google it out. This is so basic.
Anyway, just a concise explanation:
action is the attribute where you will specify the code that will handle the form data submitted and input type="submit" will display a button in the page, clicking on it will submit the form.
There are a lot of types in input, the most common ones are
text
password
submit
I have a form:
<form method="GET">
<input type="text" value="hello" name="myname" />
</form>
If this form is submitted, I will end up at:
example.com/?myname=hello
What I would prefer is that when this gets submitted, I end up at:
example.com/hello
Is this possible?
No, you cannot change the way form submission works in HTML. (Using JavaScript, you can do transactions in a different way, without using HTML form submission.) When using method="GET", the URL gets constructed in a specific way; when using method="POST", the URL does not contain submitted data at all (it is sent outside the URL).
There is a trick that changes form submission in one way, but not quite the way you want. If the name of a control is isindex, then the control name and the equals sign are omitted; but the question mark is still there. That is, <input type="text" value="hello" name="isindex" /> would result in http://www.example.com/?hello. And Chrome has broken this when they removed the remainders of support to the isindex element.
If, for some special reason, you really need to make a form create requests like http://example.com/hello, then the simplest way is to set up a very simple server-side script that accepts normal requests that result from HTML forms and just passes them forward after modifying the URL in a simple way.
I have a page that will display a search form with 3 fields, and a submit button.
when the user clicks on submit, i'm going to make an ajax call, get the data, and then populate the bottom half of the page.
What I'm wondering is if you're using ajax calls, would you still create the form using the tag?
So for example, here's some sample HTML:
<H2> Search Options</H2>
<DIV ID="searchform" class="">
<input type='text' id='id'></input>
<input type='text' id='firstname'></input>
<input type='text' id='lastname'></input>
<input type='button' id='submit'></input>
</DIV>
as you can see, I don't have a tag with post attrib set.
can you tell me why i should / shouldn't include the form tag while using ajax?
Thanks.
There is nothing wrong with it at all.
The only problem comes when a user doesn't have JavaScript enabled. How will your form behave then?
*Assuming javascript is enabled in client's browser
If you are handling Ajax call on button click event, then no need of using <form />.
Because each fields you'l get in javascript by using document.getElementByID or some other mechanism (JQuery selectors). moreover the Ajax call also you are making manually so you can avoid use of <form />.
Using <form /> will just add few bytes overhead to html page, there isn't any other advantage of using <form/> in this case, if you are handling ajax call on button Click event.
