can I use required attribute here? when I am not using form tag ? whether required works only inside form tag?
<label for="fname">First name:</label>
<input type="text" id="fname" name="fname" required>
No, as mentioned here:
The "required" attribute only works on form submit and since your
input has no form the browser does not know what to validate on
submit.
Here is also what W3C says:
When present, it specifies that an input field must be filled out before submitting the form.
So — assuming you aren't intending to use some sort of JS solution — no form, no required.
I have made a form in HTML everything must work very well but there is sth very strange about it. when I check the form on a browser I see my inputs have default values. the values I haven't give them.
"creator" for text input and ***** for password input. I don't know why it's happening I just noticed it happens when I set my password type input equal to 'password' if I change it to text everything will be fine.
this is my form
<form class="form-group">
<input type='text' class='form-control' id='user_email' placeholder="username..." Required /><br>
<input type='password' class='form-control' id='user_PassEnter' placeholder="password..." Required /><br>
</form>
I also should mention the values change when I use other browsers. for example on Chrome the text input value became ajax.
You can solve this by either:
Disabling autocomplete using <form class = "form-group" autocomplete="off">
2.Remove data from your auto-fill in the settings of your browser.
Each browser has their own way of doing it, which you can find by a simple internet search.
By suggestions, I mean the drop down menu appear when you start typing, and it's suggestions are based on what you've typed before:
For example, when I type 'a' in title field, it will give me a ton of suggestions which is pretty annoying.
How can this be turned off?
What you want is to disable HTML autocomplete Attribute.
Setting autocomplete="off" here has two effects:
It stops the browser from saving field data for later autocompletion
on similar forms though heuristics that vary by browser. It stops the
browser from caching form data in session history. When form data is
cached in session history, the information filled in by the user will
be visible after the user has submitted the form and clicked on the
Back button to go back to the original form page.

Here's an example how to do it.
<form action="#" autocomplete="on">
First name:<input type="text" name="fname"><br>
Last name: <input type="text" name="lname"><br>
E-mail: <input type="email" name="email" autocomplete="off"><br>
<input type="submit">
</form>
If it's on React framework then use as follows:
<input
id={field.name}
className="form-control"
type="text"
placeholder={field.name}
autoComplete="off"
{...fields}/>

Update
Here's an update to fix some browsers skipping "autocomplete=off" flag.
<form action="#" autocomplete="off">
First name: <input type="text" name="fname" autocomplete="off" readonly onfocus="this.removeAttribute('readonly');"><br> Last name: <input type="text" name="lname" autocomplete="off" readonly onfocus="this.removeAttribute('readonly');"><br> E-mail:
<input type="email" name="email" autocomplete="off" readonly onfocus="this.removeAttribute('readonly');"><br>
<input type="submit">
</form>
On Chrome, the only method we could identify which prevented all form fills was to use autocomplete="new-password". Apply this on any input which shouldn't have autocomplete, and it'll be enforced (even if the field has nothing to do with passwords, e.g. SomeStateId filling with state form values). See this link on the Chromium bugs discussion for more detail.
Note that this only consistently works on Chromium-based browsers and Safari - Firefox doesn't have special handlers for this new-password (see this discussion for some detail).
Update: Firefox is coming aboard! Nightly v68.0a1 and Beta v67.0b5 (3/27/2019) feature support for the new-password autocomplete attribute, stable releases should be coming on 5/14/2019 per the roadmap.
Update in 2022: For input fields with a type of password, some browsers are now offering to generate secure passwords if you've specified autocomplete="new-password". There's currently no workaround if you want to suppress that behavior, but I'll update if one becomes available.
use autocomplete="off" attribute
Quote:IMPORTANT
Put the attribute on the <input> element,
NOT on the <form> element
Adding the two following attributes turn off all the field suggestions (tested on Chrome v85, Firefox v80 and Edge v44):
<input type="search" autocomplete="off">
I know it's been a while but if someone is looking for the answer this might help. I have used autocomplete="new-password" for the password field. and it solved my problem. Here is the MDN documentation.
This solution worked for me: Add readonly attribute.
Here's an update to fix some browsers skipping the
"autocomplete=off" flag.
<input type="text" name="lname" autocomplete="off" readonly onfocus="this.removeAttribute('readonly');">
autocomplete = "new-password" does not work for me.
I built a React Form.
Google Chrome will autocomplete the form input based on the name attribute.
<input
className="scp-remark"
type="text"
name="remark"
id='remark'
value={this.state.remark}
placeholder="Remark"
onChange={this.handleChange}
/>
It will base on the "name" attribute to decide whether to autofill your form. In this example, name: "remark". So Chrome will autofill based on all my previous "remark" inputs.
<input
className="scp-remark"
type="text"
name={uuid()} //disable Chrome autofill
id='remark'
value={this.state.remark}
placeholder="Remark"
onChange={this.handleChange}
/>
So, to hack this, I give name a random value using uuid() library.
import uuid from 'react-uuid';
Now, the autocomplete dropdown list will not happen.
I use the id attribute to identify the form input instead of name in the handleChange event handler
handleChange = (event) => {
const {id, value} = event.target;
this.setState({
[id]: value,
})
}
And it works for me.
I had similar issue but I eventually end up doing
<input id="inp1" autocomplete="off" maxlength="1" />
i.e.,
autocomplete = 'off' and suggestions will be disappeared.
<input type="text" autocomplete="off"> is in fact the right answer, though for me it wasn't immediately clear.
According to MDN:
If a browser keeps on making suggestions even after setting
autocomplete to off, then you have to change the name attribute of the
input element.
The attribute does prevent the future saving of data but it does not necessarily clear existing saved data. Thus, if suggestions are still being made even after setting the attribute to "off", either:
rename the input
clear existing data entries
Additionally, if you are working in a React context the attribute naturally becomes autoComplete.
Cheers!
I ended up changing the input field to
<textarea style="resize:none;"></textarea>
You'll never get autocomplete for textareas.
If you are using ReactJS. Then make this as autoComplete="off"
<input type="text" autoComplete="off" />
The attribute pattern is not working without required and the required attribute is not yet compatible with the IOS devices.
I'm having trouble with minlength because it's not working on my code but maxlength works fine. I can't use oninvalid because I'm using a dynamic form and as well as jquery validate.
Any thoughts or recommendations?
<form method="post">
<input type="text" required pattern=".{3,}">
<input type="submit">
</form>

I've got really simple question - is there any way to disable HTML5 validation only for some chosen inputs (instead of setting "novalidate" for whole form)?
I mean something like <input type='number' requirednovalidate>. But this doesn't work.
You may ask why I need type="number" or "required" then? Well, I need it there because my framework uses it for its own validation.
EDIT
It is about one special input - birth number. I need it to be of type number (because of mobile devices) but its value is mostly used with "/" (e.g. 860518/8757) which is not valid character for type number. So I need user to fill it without slash (8605188757). The problem is when there is invalid value filled in html5 input (e.g. "fsda" in number type), it seems like it is empty, with no value.
So when user fill the value in wrong format (860518/8757), html validation is disabled so the JS validation runs, it is validated like empty field. So the error message is like "Please fill the field birth number" (which is really confusing) instead somthing like "Sorry, wrong format".
My solution was to enable html5 validation for this field (so the default browser message is displayed when there is wrong format filled) but disable it for other fields so that they would be validated only with my JS validation.
You cannot disable HTML5 validation for a chosen input(s).
If you want to remove validation on the entire form you can use formnovalidate in your input element.
For example,
<input type="submit" value="Save" class="button primary large" formnovalidate/>
Note you can use formnovalidate with <input type=submit>, <inut type=image> or <button> -source
For more info go here or here.
novalidate attribute is only for form tag, it can't be applied on form controls.
You can remove the required attribute in js, after your framework validates:
$('[Selector]').removeAttr('required');
Now the selected field will not be validated.
Inputs will be validate when:
have attr required or prop required=true
aren't empty; don't have to have attr required or prop required=true
and have no attr disabled or prop disabled=true
If you want to validate data in a specific way, use pattern attr.
