html5如何设置自动对焦,如何HTML5自动对焦添加到轨道的形式?

强烈推介IDEA2020.2破解激活,IntelliJ IDEA 注册码,2020.2 IDEA 激活码

= text_field_tag('search_text_1', params[:search_text],

options = {:type => 'search'})

产生

,我想HTML5自动对焦增加,如

= text_field_tag('search_text_1', params[:search_text],

options = {:type => 'search', :autofocus => true})

这产生

这不实际工作,但我怎么能我得到了autofocus实际的HTML输出是作为HTML规范节目,即

# Not sure where it goes or if that matters

使用

options = {:type => 'search', :autofocus }

.../_search.html.haml:2: syntax error, unexpected '}', expecting =>

...:type => 'search', :autofocus })
