Simple function to trim JS string arrays

Update, 08.05.08:
A better trimming-function:

function trimArray( array ){
    var trimmedArray = [];
     
    var item;
    for( var i = 0, len=array.length ; i < len ; i++ ){
        item = array[i];

        if( item !== '' ){
            trimmedArray.push( item );
        }
    }

    return trimmedArray; 
}

Had a case at work where I needed to make a breadcrumb-like thingy.

The breadcrumb consisted of either two or three elements, and got it's values from form-fields. Instead of checking the fields for values, I put the values in an array, trim the empty values, and join the array with a separator.

The trimming-function:

/* Trim empty strings from JS string-Arrays */
function trimStringArray( array ){
return array.join( ',' ).replace( /,{2,}/g, ',').split( ',' );
}



Testcode for the Firebug-console.
