Html 如何删除id&；rails视图帮助器中的名称属性

默认情况下，Rails从name参数为

select_tag

生成id和名称：

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

---

id

和

name

可以通过为其分配

nil

来删除：

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

选择标签nil，“David”。html\u安全，id:nil
#=>大卫

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>

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