html - 如何从 rails view helper 中删除 id 和 name 属性

Question

select_tagRails默认为 name 参数生成 id 和 name ：

select_tag "people", "<option>David</option>".html_safe
# => <select id="people" name="people"><option>David</option></select>

但是，如果我们想生成select没有 andid和name属性怎么办？
像这样：

<select><option>David</option></select>

空名称参数不起作用，空 html 属性仍然存在：

select_tag "", "<option>David</option>".html_safe
# => <select id name><option>David</option></select>

手动id和name分配不起作用

select_tag "people", "<option>David</option>".html_safe, id: false, name: false
# => <select id=false name=false><option>David</option></select>
select_tag "people", "<option>David</option>".html_safe, id: '', name: ''
# => <select id name><option>David</option></select>

Answer 1

id并且name可以通过分配nil给它来删除：

select_tag nil, "<option>David</option>".html_safe, id: nil
# => <select><option>David</option></select>
