How can I convert a string to boolean in JavaScript?

I have a select list with 2 options in it, yes or no, something like:

   <select size="1">
     <option value="true">yes</option>
     <option value="false">no</option>
   </select>

Now i want to use the selected value in the jquery-UI button disabled property , means :

  $("button").button({ disabled : $("select").val() });

Now my problem is that the value which we will get by $("select").val() is string and for

disabled property we need boolean. So i want to know that is there any method just like

pareInt or parseFloat by which we can convert a string to boolean ?

Answer 1

var value = ('true' === $("select").val() );
