ld-input #

The ld-input component can be used in forms to accept data from the user. While the native HTML input element supports a wide variety of types of input data and offers different control widgets, depending on the user agent, this component supports only a subset of the types available in the native HTML input element. All officially supported types of ld-input are documented here. Other form input widgets either have been implemented as separate components or may eventually be concidered for implementation in the future.

This component can be used in conjunction with the ld-label and the ld-input-message component.

Examples #

Default #

By default, the ld-input component is of type text.

<ld-input placeholder="Placeholder"></ld-input>

<div class="ld-input">
  <input placeholder="Placeholder">
</div>

<LdInput placeholder="Placeholder" />

With value #

<ld-input placeholder="Placeholder" value="Hello"></ld-input>

<div class="ld-input">
  <input placeholder="Placeholder" value="Hello">
</div>

<LdInput placeholder="Placeholder" value="Hello" />

Disabled #

<ld-input placeholder="Placeholder" disabled></ld-input>

<div class="ld-input ld-input--disabled">
  <input placeholder="Placeholder" disabled>
</div>

<LdInput placeholder="Placeholder" disabled />

If you want the input to stay focusable even if it is disabled, use aria-disabled in place of disabled:

<ld-input placeholder="Placeholder" aria-disabled="true"></ld-input>

<div class="ld-input ld-input--disabled">
  <input
    placeholder="Placeholder"
    aria-disabled="true"
    id="focusable-disabled-input-1">
</div>

<!-- Example code for input prevention on aria-disabled input elements -->
<script>
;(() => {
  const input = document.currentScript.previousElementSibling.querySelector('input')
  const initialValue = input.value
  input.addEventListener('input', () => {
    input.value = initialValue
  })
})()
</script>

<LdInput placeholder="Placeholder" aria-disabled="true" />

When aria-disabled is applied on the input, the component will try to prevent user input by resetting the input to its previous value on each input event. However, if you are using the CSS component version of ld-input with aria-disabled, you will have to prevent the default behaviour of the input element yourself.

Dark #

Dark tone inputs should only be used on white backgrounds.

<ld-input tone="dark" placeholder="Placeholder"></ld-input>

<div class="ld-input ld-input--dark">
  <input placeholder="Placeholder">
</div>

<LdInput tone="dark" placeholder="Placeholder" />

Invalid #

<ld-input invalid placeholder="Placeholder"></ld-input>

<div class="ld-input ld-input--invalid">
  <input placeholder="Placeholder">
</div>

<LdInput invalid placeholder="Placeholder" />

Type date #

The ld-input component of type="date" acts as a wrapper around the native input element oftype="date", fully relying on its built-in features and only enhancing it visually.
The component is lightweight, respects the user preferences for display format configured in the user's OS settings, separates presentation format from wire format and is accessible out of the box by offering a familiar UI.

<ld-input placeholder="Birthday" type="date" value="2017-06-01"></ld-input>

<div class="ld-input">
  <input placeholder="Birthday" type="date" value="2017-06-01">
</div>

<LdInput placeholder="Birthday" type="date" value="2017-06-01" />

Type datetime-local #

The ld-input component of type="datetime-local" acts as a wrapper around the native input element oftype="datetime-local", fully relying on its built-in features and only enhancing it visually.
The component is lightweight, respects the user preferences for display format configured in the user's OS settings, separates presentation format from wire format and is accessible out of the box by offering a familiar UI.

<ld-input placeholder="Birthday" type="datetime-local" value="2017-06-01T19:30"></ld-input>

<div class="ld-input">
  <input placeholder="Birthday" type="datetime-local" value="2017-06-01T19:30">
</div>

<LdInput placeholder="Birthday" type="datetime-local" value="2017-06-01T19:30" />

Type email #

Triggerts associated keyboard in supporting browsers and devices with dynamic keyboards.

<ld-input placeholder="Your email address" type="email"></ld-input>

<div class="ld-input">
  <input placeholder="Your email address" type="email">
</div>

<LdInput placeholder="Your email address" type="email" />

Type file #

<ld-input placeholder="Your profile picture" type="file" accept="image/png, image/jpeg"></ld-input>

<LdInput placeholder="Your profile picture" type="file" accept="image/png, image/jpeg" />

Handling files #

If you are using the ld-input component within a form and are posting the form, there is no need to access the selected files and the underlying data, because they are submitted as part of the form data automatically.

However, if you want to compose the form data yourself or want to read the files on the client side, you can do so using the readonly files prop.

<ld-input
  placeholder="Your profile picture"
  type="file"
  accept="image/png, image/jpeg"
></ld-input>

<script>
  ;(() => {
    const ldInput = document.currentScript.previousElementSibling
    ldInput.addEventListener('ldchange', async (ev) => {
      const files = ev.target.files
      if (!files || !files.length) return

      // Read the file on the client side.
      const fileReader = new FileReader()
      fileReader.readAsDataURL(files[0])
      fileReader.onerror = (progressEvent) => {
        // Handle error...
      }
      fileReader.onloadend = (progressEvent) => {
        // Use file data...
      }

      // Or post the file to the server.
      const data = new FormData()
      data.append('userpic', files[0])
      const requestOptions = {
        method: 'POST',
        body: data,
      }
      try {
        await fetch('/api/user/profile/picture', {
          method: 'POST',
          body: data,
        })
        // success!
      } catch (err) {
        // Handle error...
      }
    })
  })()
</script>

<LdInput
  placeholder="Your profile picture"
  type="file"
  accept="image/png, image/jpeg"
  onLdchange={async (ev) => {
    const files = ev.target.files
    if (!files || !files.length) return

    // Read the file on the client side.
    const fileReader = new FileReader()
    fileReader.readAsDataURL(files[0])
    fileReader.onerror = (progressEvent) => {
      // Handle error...
    }
    fileReader.onloadend = (progressEvent) => {
      // Use file data...
    }

    // Or post the file to the server.
    const data = new FormData()
    data.append('userpic', files[0])
    const requestOptions = {
      method: 'POST',
      body: data,
    }
    try {
      await fetch('/api/user/profile/picture', requestOptions)
      // success!
    } catch (err) {
      // Handle error...

<div class="ld-input">
  <input placeholder="Your website URL" type="url">
</div>

<LdInput placeholder="Your website URL" type="url" />

Multiline (as textarea) #

The multiline attribute transforms the component to a textarea element instead of an input element internally. Setting this attribute to true disables the attribute type and both slots.

<ld-input placeholder="Tell us your story..." multiline rows="5" cols="33"></ld-input>

<div class="ld-input">
  <textarea placeholder="Tell us your story..." rows="5" cols="33"></textarea>
</div>

<LdInput placeholder="Tell us your story..." multiline rows={5} cols={33} />

Resizing #

You can change the way how the multiline input element can be resized by the user by applying the resize prop on the ld-input element.

<ld-input resize="horizontal" placeholder="Tell us your story..." multiline rows="5" cols="33"></ld-input>

<ld-input resize="vertical" placeholder="Tell us your story..." multiline rows="5" cols="33"></ld-input>

<div class="ld-input ld-input--resize-horizontal">
  <textarea placeholder="Tell us your story..." rows="5" cols="33"></textarea>
</div>

<div class="ld-input ld-input--resize-vertical">
  <textarea placeholder="Tell us your story..." rows="5" cols="33"></textarea>
</div>

<LdInput resize="horizontal" placeholder="Tell us your story..." multiline rows={5} cols={33} />

On input message width and placement #

By default, the input field stretches to the maximum width of its wrapping label, which in turn stretches to the width of its content (the computed width of the ld-input-message component). So, if you want to set certain constraints on the width of all three components, you can do so by setting the constraint on the wrapping element – the ld-label component.

When displaying input messages conditionally (i.e. an error message becomes visible as soon as an input has been interacted with, but the value is still invalid) you should try to position UI elements in a way that prevents layout shifts. For instance, you can "reserve space" for your messages and then make them appear in the reserved space without pushing other content to the bottom (i.e. using position: absolute or some “flexy” layout). Needless to say, results look best if you keep the messages short.

With slotted elements #

You can use slots in order to add static or interactive elements, such as icons or buttons into the input component.

The Web Component ld-input listens for click events on the contained ld-icon component and automatically focuses the input field on icon click. The CSS component version of ld-input doesn't do that.

Input validation #

The ld-input Web Component does not provide any properties or methods for validating the input value internally. Instead, it provides a low level API for integrating the component with the form validation solution of your choice. It allows you to listen for focus, input and blur events, as well as custom events (see Events for details).

You can find examples for different kinds of input validation in the Form validation documentation. Please also be aware of differences in event handling compared to native elements that come with Web Components. Details can be found in our Event handling documentation.

Overview #

The ld-input component. You can use it in conjunction with the ld-label and the ld-input-message component. See examples in the docs for a better understanding on how they can be used together.
