function isvalid( str ){    var is_valid = true;   if(str.indexof('-') === -1){      is_valid = false;   }   return is_valid; }

but want combine method checks multiple - , empty spacing between characters.

example enter string this. var str = "emp t y" want check if empty space present or if this. var str = "12-34-55"
