Here is the code for the random number combining integer
and character
<%=(0...4).map { ('a'..'z').to_a[rand(26)] }.join %> <%=rand(1..2000)%>
Gives output like:
tqzu 1664
But when i put this into textbox like;
<input type = "text" value=<%=(0...4).map { ('a'..'z').to_a[rand(26)] }.join %><%=rand(1..2000)%> />
OUTPUT
ztgg
Question:-
how to get the value of random number into textbox with the combination of char and integer
?
It only processes the first part. If you place your code in a helper you can call the helper method within your view and you shouldn't have any problems.
You have to put your code into "
:
<input type = "text" value="<%=(0...4).map { ('a'..'z').to_a[rand(26)] }.join %> <%=rand(1..2000)%>" />
or better:
# in helper
def code
[(0...4).map { ('a'..'z').to_a[rand(26)] }.join,
rand(1..2000)].join(' ')
end
# in view
<%= tag :input, :value => code %>
In your form place code like this
<%=@rand_value = (0...4).map { ('a'..'z').to_a[rand(26)] }.join.to_s + rand(1..2000).to_s %>
<%= f.text_field :text, :value => @rand_value %>
or you can use text_field_tag as below:
<%= text_field_tag "text", @rand_value %>
