jquery替换不适合'['

Question

我想将'[0'替换为'['和'[1'替换为'['

var sign ='[[1,17.5,24],[0,17.5,25],[0,17.5,26],[0,17.5,31],,,,[0,280.5,47],[0,282.5,49]]';
   sign.replace('[0,','[').replace('[1,', '[')
      alert(sign)

但是那里有相同的价值

Expected:[[17.5,24],[17.5,25],[17.5,26],[17.5,31],[280.5,47],[282.5,49]]

请帮忙
