实例公共方法

rich_text_area_tag(name, value = nil, options = {})

rich_textarea_tag(name, value = nil, options = {})

返回一个trix-editor标签,该标签实例化Trix JavaScript编辑器,以及一个隐藏字段,Trix将在更改时写入该字段,因此内容将在表单提交时发送。

选项

  • :class - 默认值为“trix-content”,以便应用默认样式。将此设置为其他值将阻止应用默认样式。

  • [:data][:direct_upload_url] - 默认值为rails_direct_uploads_url

  • [:data][:blob_url_template] - 默认值为rails_service_blob_url(":signed_id", ":filename")

示例

rich_textarea_tag "content", message.content
# <input type="hidden" name="content" id="trix_input_post_1">
# <trix-editor id="content" input="trix_input_post_1" class="trix-content" ...></trix-editor>
也称为:rich_text_area_tag

  editor_tag = content_tag("trix-editor", "", options)
  input_tag = hidden_field_tag(name, value.try(:to_trix_html) || value, id: options[:input], form: form)

  input_tag + editor_tag
