Mutual conversion between js arrays and strings. Mutual conversion between js Arrays

Many of my friends who are familiar with js have encountered the conversion between js arrays and strings. This article gives a brief introduction. The example is as follows:

I. Convert arrays to strings

The array element needs to be connected to a string using a character. The sample code is as follows:

Var a, B; a = new Array (0, 1, 2, 3, 4); B = a. join ("-");

Ii. Convert string to array

The implementation method is to cut the string into several strings by a specific character and return the strings in array form. The sample code is as follows:

Var s = "abc, abcd, aaa"; ss = s. split (","); // separate each comma.

JS converts an array string into an array

Var B = eval ('+ txtResult. value + ')');

How to convert JavaScript strings to arrays if they are not converted to string arrays?

The numbers are the same, and js is not sensitive to types.
