Multi-dimensional array implemented by JavaScript

To define multi-dimensional arrays in C #, you can use this simple code: [csharp] int [,] myArraynewint []; In JavaScript, you cannot directly define multi-dimensional arrays, how can this problem be achieved? First define a one-dimensional array: [javascript] varmyArraynewA... SyntaxH

To define multi-dimensional arrays in C #, you can use the following simple code:
[Csharp]
Int [,] myArray = new int [4, 5];

In JavaScript, multi-dimensional arrays cannot be defined directly. How can this problem be achieved?
First, define a one-dimensional array:
[Javascript]
Var myArray = new Array ();
Then, define the members of the one-dimensional array as an array (the reason why it can be redefined is that JavaScript is of a weak type ):
[Javascript]
MyArray [0] = new Array ();
So far, a two-dimensional array with the first index of 0 is defined. If you want to use a two-dimensional array with the first index of 1, you still need to define it before use:
[Javascript]
MyArray [1] = new Array ();

The following is an example of a JavaScript multi-dimensional array application, which is used to store the questions and answers of multiple-dimensional arrays:
