How to get value of Object from List in jQuery? Ath the moment I'm getting List of ActionResults from controller and I want to get value of each action (html code).

There is't a problem when I try to send single ActionResult - without list.

When I try to send List<ActionResult> I get object Object every time.

<script type="text/javascript">
    $(document).on('click', 'button', function () {
        $cartAction = $("#" + this.id);
        var url = $cartAction.data("url");
        $.get(url, function (actions) {
           console.log(actions); <-- return Objects Array
           console.log(???); <-- how to get value of each actions
           console.log(actions[1]); <-- return a single object
           console.log(actions[1].document) <-- value undefined
        });
    });
</script>

public ActionResult Index()
{
    var actionList = new List<ActionResult>()
    {
        // ViewComponents, PartialViews
    };
    return Json(actionList);
}

I expect return html code for each ActionResult, but I get

[object Object],[object Object]

for actions list.

Alter table commands take so long to execute

I'm trying to create 4 table hierarchy - Sport Category, League, Team and Player. Till this moment this is what I have created:

      -- Create PLAYER table
create table PLAYER
(
  PLAYER_ID           INT not null,
  NAME_OF_PLAYER         VARCHAR(36) not null,
  NUMBER_OF_PLAYER      INT not null,
  TEAM_ID                   INT not null
) ;

alter table PLAYER
  add constraint PLAYER_PK primary key (PLAYER_ID);

alter table PLAYER MODIFY COLUMN PLAYER_ID INT auto_increment;

alter table PLAYER
  add constraint PLAYER_UK unique (NAME_OF_PLAYER, TEAM_ID);


     -- Create TEAM table
create table TEAM
(
  TEAM_ID           INT not null,
  NAME_OF_TEAM          VARCHAR(36) not null,
  LEAGUE_ID         INT not null
) ;

alter table TEAM
  add constraint TEAM_PK primary key (TEAM_ID);

alter table TEAM MODIFY COLUMN TEAM_ID INT auto_increment;

alter table TEAM
  add constraint TEAM_UK unique (NAME_OF_TEAM);



    -- Create LEAGUE table
create table LEAGUE
(
  LEAGUE_ID           INT not null,
  NAME_OF_LEAGUE          VARCHAR(36) not null,
  SPORT_CATEGORY_ID         INT not null
) ;

alter table LEAGUE
  add constraint LEAGUE_PK primary key (LEAGUE_ID);

alter table LEAGUE MODIFY COLUMN LEAGUE_ID INT auto_increment;

alter table LEAGUE
  add constraint LEAGUE_UK unique (NAME_OF_LEAGUE);



   -- Create Sport_Category table
create table SPORT_CATEGORY
(
  SPORT_CATEGORY_ID           INT not null,
  NAME_OF_CATEGORY          VARCHAR(36) not null
) ;

alter table SPORT_CATEGORY
  add constraint SPORT_CATEGORY_PK primary key (SPORT_CATEGORY_ID);



alter table SPORT_CATEGORY MODIFY COLUMN SPORT_CATEGORY_ID INT auto_increment;



alter table SPORT_CATEGORY
  add constraint SPORT_CATEGORY_UK unique (NAME_OF_CATEGORY);



alter table PLAYER
  add constraint PLAYER_FK foreign key (TEAM_ID)
  references TEAM (TEAM_ID);

alter table TEAM
  add constraint TEAM_FK1 foreign key (LEAGUE_ID)
  references LEAGUE (LEAGUE_ID);


alter table LEAGUE
  add constraint LEAGUE_FK1 foreign key (SPORT_CATEGORY_ID)
  references SPORT_CATEGORY (SPORT_CATEGORY_ID);

When I execute the this sql file, it takes like 15 seconds to finish. With some testing I noticed that alter table statements make it slower. Is this normal for this kind of relation tables? Is it because of the complexity of the tables?

I'm new to working with relations but very enthusiastic about it. Any help will be appreciated.

解决方案

在 jQuery 中，您可以像这样遍历值

<script type="text/javascript">
    $(document).on('click', 'button', function () {
        $cartAction = $("#" + this.id);
        var url = $cartAction.data("url");
        $.get(url, function (actions) {
           console.log(actions); // <-- return Objects Array
           $.each(function() { // <-- iterates through each object in actions array
               console.log($(this)); // <-- logs the object to the console
           });
           console.log(actions[1]); // <-- return a single object
           console.log(actions[1].document) // <-- value undefined
        });
    });
</script>

在大多数浏览器中甚至console.log(actions);可以工作。但你总是可以JSON.stringify(actions);
