如何将嵌入的字符串数组转换为数组javascript(How to convert embedded string array into array javascript)

我有一个字符串格式的数组。 我如何将其转换为数组。

my_data="['A','B','C']"  (Note the quotes around [])
convert this to ['A','B','C']

到目前为止,我尝试了json.parse和其他字符串到数组对话没有运气。 有人可以帮忙吗?


I have an array coming in string format. How do i convert it to an array.

我认为一个样本脚本价值超过1000字:

转到firebird服务器计算机中的shell接口,cd到您具有读/写权限的文件夹,启动isql或isql-fb(取决于您的系统和firebird版本)并运行此脚本:

create database 'netmajor.fdb' user 'sysdba' password 'masterkey';
set autoddl off;

create table netmajor_example (
    netmajor_id     integer not null
  , str_data        varchar(200)
  , int_data        integer
  , constraint pk_netmajor_example
      primary key (netmajor_id)
);

create generator netmajor_gen;

set term ^;

create trigger netmajor_pkassign
   for netmajor_example
active before insert position 1
AS
begin
  if (new.netmajor_id is null) then
    new.netmajor_id = gen_id(netmajor_gen, 1);
end
^

commit work^

set term ; ^


insert into netmajor_example (str_data, int_data) values ('one', 1);
insert into netmajor_example (str_data, int_data) values ('twenty', 20);
commit work;

select * from netmajor_example;

看看我的机器中的结果:

; NETMAJOR_ID STR_DATA                     INT_DATA
;============ ============================ ============
;           1 one                                     1
;           2 twenty                                 20

如果您有任何疑问,请随时联系。 最好的祝福。


I think a sample script worths more than 1000 words:

Go to a shell interface in the firebird server machine, cd to a folder where you have read/write permissions, start isql or isql-fb (depends on your system and firebird version) and run this script:

create database 'netmajor.fdb' user 'sysdba' password 'masterkey';
set autoddl off;

create table netmajor_example (
    netmajor_id     integer not null
  , str_data        varchar(200)
  , int_data        integer
  , constraint pk_netmajor_example
      primary key (netmajor_id)
);

create generator netmajor_gen;

set term ^;

create trigger netmajor_pkassign
   for netmajor_example
active before insert position 1
AS
begin
  if (new.netmajor_id is null) then
    new.netmajor_id = gen_id(netmajor_gen, 1);
end
^

commit work^

set term ; ^


insert into netmajor_example (str_data, int_data) values ('one', 1);
insert into netmajor_example (str_data, int_data) values ('twenty', 20);
commit work;

select * from netmajor_example;

Take a look at the results, which in my machine are:

; NETMAJOR_ID STR_DATA                     INT_DATA
;============ ============================ ============
;           1 one                                     1
;           2 twenty                                 20
