Rails:如何为hidden_​​field_tag分配名称和ID？

Question

如何为hidden_​​field_tag分配特定的ID和名称？

像这样,

hidden_field_tag(:id => "page_no",:name => "page", :value => "1" )

任何的想法!

Answer 1

hidden_field_tag("page_name", "1", :id => "page_no")

根据http://api.rubyonrails.org/classes/ActionView/Helpers/FormTagHelper.html#method-i-hidden_​​field_tag

Answer 2

它需要 hidden_field_tag(name, value = nil, options = {})

所以第三个参数是选项.

hidden_field_tag("page", "1", {:id => "page_no"}) 将名称设置为"page",将值设置为"1"并将id设置为"page_no"
