例如我有一个字符串 var str = 'dog,[cat,lion],[bird,chicken,duck]'; 我希望把他转成一个数组: arr = [dog,[cat,lion],[bird,chicken,duck]];
应该怎么操作呢？困扰了一个晚上 T_T
业精于勤，荒于嬉;行成于思，毁于随。
var str = 'dog,[cat,lion],[bird,chicken,duck]'; JSON.parse('['+str.replace(/\w+/g, function(a){return '"'+a+'"'})+']')
eval 也行，
var str = 'dog,[cat,lion],[bird,chicken,duck]'; eval('['+str.replace(/\w+/g, function(a){return '"'+a+'"'})+']')
