This article mainly introduces how to implement multi-dimensional arrays in JavaScript. If you need to implement multi-dimensional arrays, refer to defining multi-dimensional arrays in C #. You can use this simple code:
The Code is as follows:
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:
The Code is as follows:
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 ):
The Code is as follows:
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:
The Code is as follows:
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:
The Code is as follows:
