String.prototype.wordWrap = function(m, b, c){
var i, j, l, s, r;
if(m < i =" -1," l =" (r" s =" r[i],"> m; r[i] += s.slice(0, j) + ((s = s.slice(j)).length ? b : ""))
j = c == 2 || (j = s.slice(0, m + 1).match(/\S*(\s)?$/))[1] ? m : j.input.length - j[0].length
|| c == 1 && m || j.input.length + (j = s.slice(m).match(/^\S*/)).input.length;
return r.join("\n");
};
Định dạng hàm:
String.wordWrap(maxLength: Integer, [breakWith:String="\n"],
[cutType:Integer = 0]): String

Kết quả:

Returns an string with the extra characters/words "broken".

maxLength: maximum amount of characters per line

breakWtih: string that will be added whenever it's needed to break the line

cutType:
0 = words longer than "maxLength" will not be broken
1 = words will be broken when needed
