Question

我目前正在搞乱多维数组，以存储一些涉及多个连接表和每个内部多个字段的信息。我正在使用jQuery.ajax（）抓取数据并使用.each输出它，所有这些工作正常，但现在我正在尝试设置数组，Chrome控制台显示未定义的值，当我从我可以看到应该设置它们。设置的唯一一个是循环的最后一次传递。

这就是我在循环中设置数组的原因：

    gAuthrequests[gAuthrqcount][1] = [];
    gAuthrequests[gAuthrqcount][1][i] = [];
    gAuthrequests[gAuthrqcount][1][i][0] = val.KRANE_REQUEST_DETAILS_ID;
    gAuthrequests[gAuthrqcount][1][i][1] = comments;
    gAuthrequests[gAuthrqcount][1][i][2] = 0;
    i++;

我知道循环有效，因为它输出正常，我也在一点使用console.log来跟踪这些行的数组进度，一切看起来都很好，这是输出：

    KRID: (96) Assign Var: gAuthrequests[7][1][0][0]: 63
    KRID: (96) Assign Var: gAuthrequests[7][1][0][1]: No comments
    KRID: (96) Assign Var: gAuthrequests[7][1][0][2]: 0
    KRID: (96) Set var: gAuthrequests[7][1]:
    KRID: (96) Set var: gAuthrequests[7][1][1]:
    KRID: (96) Assign Var: gAuthrequests[7][1][1][0]: 64
    KRID: (96) Assign Var: gAuthrequests[7][1][1][1]: No comments
    KRID: (96) Assign Var: gAuthrequests[7][1][1][2]: 0
    KRID: (96) Set var: gAuthrequests[7][1]:  okr.js:360
    KRID: (96) Set var: gAuthrequests[7][1][2]:
    KRID: (96) Assign Var: gAuthrequests[7][1][2][0]: 65
    KRID: (96) Assign Var: gAuthrequests[7][1][2][1]: No comments
    KRID: (96) Assign Var: gAuthrequests[7][1][2][2]: 0
    KRID: (96) Set var: gAuthrequests[7][1]:
    KRID: (96) Set var: gAuthrequests[7][1][3]:
    KRID: (96) Assign Var: gAuthrequests[7][1][3][0]: 66
    KRID: (96) Assign Var: gAuthrequests[7][1][3][1]: I want access to this this this this this
    KRID: (96) Assign Var: gAuthrequests[7][1][3][2]: 0

在这个例子中，唯一要设置的变量是'gAuthrequests [7] [1] [3]'（66）之前的3是未定义的

Answer 1

使用对象数组结束：

在第一次循环之前

： 'gRQCount = [];'

在第二次循环之前： 'var i = 0;'

循环：

    gAuthrequests[gRQCount][i] = {};
    gAuthrequests[gRQCount][i].krid = krid;
    gAuthrequests[gRQCount][i].krdid = val.KRANE_REQUEST_DETAILS_ID;
    gAuthrequests[gRQCount][i].cylinder = cylinderrecid;
    gAuthrequests[gRQCount][i].comments = comments;
    gAuthrequests[gRQCount][i].status = 0;
    i++

设置多维数组的值未定义
