在JQuery中创建数组的数组

Question

我想知道如何在JQuery中创建2D数组的等效项

从研究中，我可以看到JQuery不支持2d数组，但是我想知道是否有可能从数组中的数组创建一个。

我想做的是拥有一个可容纳数周的数组，而该数组内部可容纳7天。

从收集的研究中，我似乎想要这样的东西：

{
 "Week":
 [
     {
      "Day":"Monday",
      "Day":"Tuesday",
      "Day":"Wednesday",
      "Day":"Thursday",
      "Day":"Friday",
      "Day":"Saturday",
      "Day":"Sunday"
     }
 ]
}

所以

week[1,2,3,4,5,6,7,8,9,10]
day[Monday,Tuesday, Wednesday, Thursday, Friday,Saturday, Sunday]

因此，有效地将周作为行的索引，将日作为列的索引。

这实际上可行吗？ 我习惯了Java，jQuery对我来说很奇怪。

Answer 1

使用javascript的数组中的数组： var a = [[1],[2]] 。

访问数据： a[1][0] -> 2 。

我不确定要了解您需要做什么。 在javascript中，您可以创建array数组。 因此，如果您尝试在一周内的一天内将其存储在数组中，则可以执行以下操作：

var weeks = [
    ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
    ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
    //...
    ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
    ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
    ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"]
]

console.log(weeks[0][0]); //"Monday"
console.log(weeks[0]); //array["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"]

或者您可以像2d关联数组一样使用js OBJECT：

var weeks = {
    "week1" : ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
    "week2" : ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
    "week3" : ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
   //...
    "week8" : ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
    "week9" : ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
    "week10" : ["Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"],
}

console.log(weeks.week1[0]); //monday
console.log(weeks.week1); //["Monday",...,"Sunday"]

:)希望它能有所帮助。

Answer 3

您可以生成类似于其他编程语言的多个数组。

生成这种数组的最短方法是：

[[],[]]

如之前帖子中所述。

但是对于您的问题，我建议您首先创建一个日数组，如下所示：

var days = ['Monday', 'Tuesday', '...'];

然后，您可以像下面这样引用这个天数组：

var weeks = [days, days, days, days, ...];

这将节省资源，因为始终只有一个指向同一天数组的指针。 而不是每周都有新的天数数组。

祝你今天愉快。
