Description
sp-textfield
components are text boxes that allow users to input custom text entries with a keyboard. Various decorations can be displayed around the field to communicate the entry requirements.
Usage
yarn add @spectrum-web-components/textfield
Import the side effectful registration of <sp-textfield>
via:
import '@spectrum-web-components/textfield/sp-textfield.js';
When looking to leverage the Textfield
base class as a type and/or for extension purposes, do so via:
import { Textfield } from '@spectrum-web-components/textfield';
Example
<sp-field-label for="name-0">Name</sp-field-label>
<sp-textfield id="name-0" placeholder="Enter your name"></sp-textfield>
Variants
Valid
Dictate the validity state of the text entry with the valid
attribute.
<sp-field-label for="name-1" required>Name</sp-field-label>
<sp-textfield
id="name-1"
placeholder="Enter your name"
valid
value="My Name"
></sp-textfield>
Invalid
Dictate the invalidity state of the text entry with the invalid
attribute.
<sp-field-label for="name-2" required>Name</sp-field-label>
<sp-textfield id="name-2" invalid placeholder="Enter your name"></sp-textfield>
Quiet
The quiet style works best when a clear layout (vertical stack, table, grid) assists in a user's ability to parse the element. Too many quiet components in a small space can be hard to read.
<sp-field-label for="name-3">Name (quietly)</sp-field-label>
<sp-textfield id="name-3" placeholder="Enter your name" quiet></sp-textfield>
Types
When inputting URLs, telephone numbers, email addresses, or passwords, specify a type
to provide
user affordances like mobile keyboards and obscured characters:
url
tel
email
password
text
(default)
<sp-field-label for="tel-1">Telephone</sp-field-label>
<sp-textfield
id="tel-1"
type="tel"
placeholder="Enter your phone number"
></sp-textfield>
<sp-field-label for="password-1">Password</sp-field-label>
<sp-textfield id="password-1" type="password"></sp-textfield>
If the type
attribute is not specified, or if it does not match any of these values, the default type adopted is "text."
Help text
Help text can be accessibly associated with an <sp-textfield>
element by using the help-text
or negative-help-text
slots. When using the negative-help-text
slot, <sp-textfield>
will self manage the presence of this content based on the value of the invalid
property on your <sp-textfield>
element. Content within the help-text
slot will be show by default. When your <sp-textfield>
should receive help text based on state outside of the complexity of invalid
or not, manage the content addressed to the help-text
from above to ensure that it displays the right messaging and possesses the right variant
.
Self managed
<sp-field-label for="self">Stay "Positive"</sp-field-label>
<sp-textfield id="self" pattern="[P][o][s][i][t][i][v][e]" value="Positive">
<sp-help-text slot="help-text">
Tell us how you are feeling today.
</sp-help-text>
<sp-help-text slot="negative-help-text">Please be "Positive".</sp-help-text>
</sp-textfield>
Managed from above
<sp-field-label for="managed">Stay "Positive"</sp-field-label>
<sp-textfield
id="managed"
pattern="[P][o][s][i][t][i][v][e]"
value="Positive"
oninput='
const helpText = this.querySelector(`[slot="help-text"]`);
helpText.textContent = this.invalid ? `Please be "Positive".` : `Tell us how you are feeling today.`;
helpText.variant = this.invalid ? `negative` : `neutral`;
'
