javascript - Coffee script access to input value -

i new javascript, coffee script, jquery , ui tech in general. trying accomplish simple thing - read value input field far no luck. code pretty simple:

    <div class="ui-widget">         <label for="tags">tags: </label>         <input id="tags" value="hello">     </div> 

from coffee script trying read value follows:

jquery ($) ->     $field = $('.ui-widget input') text=$field.val alert #{ text } 

but far no luck, contrary via $field.val("bye") works fine.

could please put shed on that?

thx

parameter less function calls require parentheses.

text=$field.val 

is translated

var text;  text = $field.val; 

notice getting function reference val

adding parans:

text=$field.val() 

becomes

var text;  text = $field.val(); 

returning result of function rather function itself.
