javascript boolean object

crmpicco · April 20th, 2006, 06:14 AM

Code:

var bOneway = Boolean(document.form.oneWay.value); // contains 'False'
var bReturn = Boolean(document.forms["form"].elements["return"].value); // contains 'True'
var bOpenjaw = Boolean(document.form.openJaw.value); // contains 'False'

I am trying to change these form fields to Booleans in javascript. But the code above just sets them all to true??

Hi Crmpicco!!
here is the answer to your question
http://www.javascriptkit.com/jsref/boolean.shtml

it describes when it returns to true and when to false.

Hope this will help you

Cheers :)

yeah, it seems you can change an object's value to a boolean though

Basically, if the value passed to the Boolean object is anything but 0, null, false, etc., it'll return true.

But I think the issue here is this:

var test1 = Boolean(false); // this returns false
var test2 = Boolean('False'); // this returns true
var test3 = Boolean('false'); // this also returns true

false isn't equal to 'false', nor is it equal to 'False'
