Question

I am building a plugin which has a option where a user can set which element should right (default is left), the idea is for an menu, which has the option that a user can say, the first sub menu and the third submenu should float to the right, but i cant seem to get it to work, if i add one value it works, but once i add more values it doesn’t work.

// plugin options

var defaults = {
    floatRight:      [1,5,6,9]
}
var opt = jQuery.extend(defaults, o);

// the loop

var i = 0
$('li').each(function(){
   if((jQuery.inArray(i, o.floatRight)) == '-1'){
      // add class...
   }
  i++;
});

Answer 1

It looks like you want to use opt rather than o?

$('li').each(function(i){
   if((jQuery.inArray(i, opt.floatRight)) !== -1){
      // add class...
   }
});

Also, change the comparison to !== as I’m assuming you want to add the class if it is floated on the right?
