<%= select_tag 'pseudo-attribute', options_for_select(...), :include_blank => 'Nowhere'%>
此标记用于包含“无处”的空白选项,但现在文本框为空白,有人知道原因吗?
答案 0 :(得分:8)
现在select标签的代码是(Rails 3.1.0.rc4)
def select_tag(name, option_tags = nil, options = {})
html_name = (options[:multiple] == true && !name.to_s.ends_with?("[]")) ? "#{name}[]" : name
if options.delete(:include_blank)
option_tags = "<option value=\"\"></option>".html_safe + option_tags
end
if prompt = options.delete(:prompt)
option_tags = "<option value=\"\">#{prompt}</option>".html_safe + option_tags
end
content_tag :select, option_tags, { "name" => html_name, "id" => sanitize_to_id(name) }.update(options.stringify_keys)
end
表示您必须将:include_blank
替换为:prompt
。如果您想在选择字段中选择空白,请使用包含空白:)
