How to deal with <%= text_field %> in ruby on rails when javascript is used

I used the JavaScript as:

script language="javascript"

function writeResult(text){ document.myform.tDescription.value = text;

}

/script

hence my text field will be:

form="myform" <%= s.text_field 'xyz','abc', :name =>('tDescription'), :size =>50 %> /form

I have to store this text value in the table 'xyz' in column 'abc' but its not working. As ruby on rails by default take the text field name as name="xyz[abc]" , if i m not specifing any name for the text field but becoz of java script the function call I have specify the name as tDescription. Please help how I can store this value in database. If i use input tag instead. What will the controller corresponding code.

give your textfield a unique id

<%= s.text_field 'xyz','abc', :id => "tdescription", :size =>50 %>

now you can have your javascript refer to the id and let rails use name for its uses

either go by classic javascript 

getElementById('tdescription')

or my preference use jquery

$('#tdescription')....
