[RAILS] [For super beginners] How to use autofocus: true

autofocus attribute

"Autofocus: true" means that as soon as the page is loaded, the cursor moves to the part where the autofocus attribute is described and the input state is entered.

Concrete example

When you move from the list page to My Page and try to change the name.   If you click the My Page button from the list page to go to My Page, My Page will be displayed with the cursor moved even if you do not select the form part of your name. So you can edit it right away! カーソルが移動して入力状態になる

⚠️ Keep in mind that autofocus: true is limited to one per html file.

How to write

Here, the code of the above image is introduced as it is. Let's understand how "autofocus: ture" is used in the whole. Environment: rails 6.0.0, VScode 1.46, macOS Catalina 10.15


<div class="account-page">
  <div class="account-page-title">
    <h1>My page</h1>
  <div class="account-info">
    <h2>User information</h2>
  <div class="account-page-form">
    <%= form_for(current_user) do |f| %>
      <div class="form-field">
        <div class="form-field-name">
          <%= f.label :name %>
        <div class="form-field-name">
          <%= f.text_field :name, autofocus: true %>
      <div class="form-field">   
        <div class="form-field-email">
          <%= f.label :email %>
        <div class="form-field-email">
          <%= f.email_field :email %>
      <%= f.submit "Update" %>
