这对我有用 form_with 模型和引导程序
更改my_hidden_form并使用对您的表单有意义的 id。
原始代码是haml
= form_with scope: :model, url: models_path, local: true do |form|
.row
.col-6
.form-group
%h5.mb0 THE CASE TO TICK
= form.check_box :form_value, {:data => {:aria => {controls: :my_hidden_form, expanded: false}, :toggle => "collapse", :type => "checkbox", :target => "#my_hidden_form" }}
.row
.col-6
.form-group.collapse#my_hidden_form
%h5.mb0 THE FORM TO SHOW WHEN CASE IS TICKED
= form.text_field :name, placeholder: "A name"
.row
.col-md-12.text-right
= form.submit 'Submit', class: "btn btn-primary"
使用https://haml2erb.org/转换为 erb/html
<%= form_with scope: :model, url: models_path, local: true do |form| %>
<div class="row">
<div class="col-6">
<div class="form-group">
<h5 class="mb0">THE CASE TO TICK
<%= form.check_box :form_value, {:data => {:aria => {controls: :my_hidden_form, expanded: false}, :toggle => "collapse", :type => "checkbox", :target => "#my_hidden_form" }} %>
</h5>
</div>
</div>
</div>
<div class="row">
<div class="col-6">
<div class="form-group collapse" id="my_hidden_form">
<h5 class="mb0">THE FORM TO SHOW WHEN CASE IS TICKED
<%= form.text_field :name, placeholder: "A name" %>
</h5>
</div>
</div>
</div>
<div class="row">
<div class="col-md-12 text-right">
<%= form.submit 'Submit', class: "btn btn-primary" %>
</div>
</div>
<% end %>
