window.getComputedStyle error in FireFox

[Sevin777]

the Selectize function that gets direction (ltr,rtl) from the input throws an error when using FireFox if Selectize is called in an iframe with display:none;

This is a known issue with FireFox.

The issue can easily be solved in selectize by modifying the following code:

dir = window.getComputedStyle ? window.getComputedStyle(input, null).getPropertyValue('direction') : input.currentStyle && input.currentStyle.direction;
dir = dir || $input.parents('[dir]:first').attr('dir') || '';

Change to:

var alternativeGetDir=function(){
    return input.currentStyle && input.currentStyle.direction  || $input.parents('[dir]:first').attr('dir') || '';
};
try{          
    dir = window.getComputedStyle ? window.getComputedStyle(input, null).getPropertyValue('direction') : alternativeGetDir();
}
catch(ex){
    //will throw error in FF if loaded in iframe with display:none
    dir = alternativeGetDir();
}
