@spectrum-web-components/textfield

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';

Sizes

Small

<sp-field-label size="s" for="name-0-s">Name</sp-field-label>
<sp-textfield
    size="s"
    id="name-0-s"
    placeholder="Enter your name"
></sp-textfield>

Medium

<sp-field-label for="name-0-m">Name</sp-field-label>
<sp-textfield id="name-0-m" placeholder="Enter your name"></sp-textfield>

Large

<sp-field-label size="l" for="name-0-l">Name</sp-field-label>
<sp-textfield
    size="l"
    id="name-0-l"
    placeholder="Enter your name"
></sp-textfield>

Extra Large

<sp-field-label size="xl" for="name-0-xl">Name</sp-field-label>
<sp-textfield
    size="xl"
    id="name-0-xl"
    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`;
    '
>
    <sp-help-text slot="neutral-text">
        Tell us how you're feeling today.
    </sp-help-text>
    <sp-help-text slot="help-text">Please be "Positive".</sp-help-text>
</sp-textfield>
