pug - adding attribute in input field of Jade with javascript variable -

i want add attribute in input field local javascript variable as:

-var requiredfield = ('agent' == user.account_type.tolowercase()) ? 'required' : '';  input(type='text', name="name", placeholder="name", "#{requiredfield}") 

but attribute #{requiredfield} in html. how can achieved?

i using jade. in advance

jade smart enough render required attribute based off of boolean value: required=true or required=false.

   input(type='text',required=true)    input(type='text',required=false) 

will render out as:

<input type='text' required /> <input type='text' /> 

so code sample, try instead:

-var isrequired = 'agent' == user.account_type.tolowercase(); input(type='text', name="name", placeholder="name", required=isrequired)
