Я думаю, что могу сказать, с некоторой определенностью, * да *. –

[Что вы пытались?] (Http://mattgemmell.com/what-have-you-tried/) –

Я играл с .substr() и .slice(), но я смущен тем, как захватите странные символы перед 'fa-' like ''. Я попытался использовать replace(), чтобы захватить .substr() раньше, но не могу заставить его работать. –

Вы можете использовать регулярное выражение для поиска действительных имен классов, начиная с fa-.

//A string you want to extract the classes from. 
var exampleString = 'fa-deviantart[]fa-diamond[]'; 

//Extract the class names using a regex into an array. 
var classList = exampleString.match(/fa\-[a-zA-Z0-9\-_]*/g); 

//Create a new string from the array of matched classes. 
alert(classList.join(' '));
