Examples

Let’s explore some practical examples of using the autocomplete property with search input fields.

Example 1: Basic Autocomplete On

This example enables autocomplete for a search input field. The browser will suggest search terms based on previous entries.

<form>
  <label for="search-input-on">Search:</label>
  <input
    type="search"
    id="search-input-on"
    name="search"
    autocomplete="on"
  />
  <button type="submit">Search</button>
</form>

In this case, as the user types, the browser provides suggestions based on past searches.

Example 2: Disabling Autocomplete

This example disables autocomplete for a search input field. The browser will not suggest any entries.

<form>
  <label for="search-input-off">Search:</label>
  <input
    type="search"
    id="search-input-off"
    name="search"
    autocomplete="off"
  />
  <button type="submit">Search</button>
</form>

With autocomplete="off", the browser does not provide any suggestions, giving the user a clean, unassisted search experience.

Example 3: Using Autocomplete with a Data List

To provide specific suggestions, you can use a <datalist> element in combination with the list attribute.

<form>
  <label for="search-input-list">Search:</label>
  <input
    type="search"
    id="search-input-list"
    name="search"
    list="search-suggestions"
  />
  <datalist id="search-suggestions">
    <option value="JavaScript"></option>
    <option value="HTML"></option>
    <option value="CSS"></option>
    <option value="Web Development"></option>
  </datalist>
  <button type="submit">Search</button>
</form>

This example provides a predefined list of suggestions (JavaScript, HTML, CSS, Web Development) that appear as the user types in the search input field.

Example 4: Autocomplete with Name and Email

This example demonstrates using specific autocomplete types for name and email input fields within a form.

<form>
  <label for="name">Name:</label>
  <input type="text" id="name" name="name" autocomplete="name" /><br /><br />

  <label for="email">Email:</label>
  <input type="email" id="email" name="email" autocomplete="email" /><br /><br />

  <label for="country">Country:</label>
  <input
    type="text"
    id="country"
    name="country"
    autocomplete="country-name"
  /><br /><br />

  <label for="postal-code">Postal Code:</label>
  <input
    type="text"
    id="postal-code"
    name="postal-code"
    autocomplete="postal-code"
  /><br /><br />

  <button type="submit">Submit</button>
</form>

This code snippet pre-fills the form fields with stored information based on the autocomplete attribute values, enhancing the user experience by reducing the need for manual input.

Tips and Best Practices

Consider user privacy: Be mindful of the data you’re storing and suggesting. Provide options for users to clear their search history. 🛡️
Test across browsers: Autocomplete behavior can vary between browsers, so test your implementation thoroughly.
Combine with data lists: For specific suggestions, use the <datalist> element to provide a controlled set of options.
