toString() method returns a string representing the specified array and its elements. This method has the same algorithm as Array.prototype.toString() . TypedArray is one of the typed array types here.

句法

typedarray.toString()
					

返回值

A string representing the elements of the typed array.

范例

TypedArray objects override the toString 方法为 Object . For TypedArray objects, the toString method joins the array and returns one string containing each typed array element separated by commas. For example, the following code creates a typed array and uses toString to convert the array to a string.

var numbers = new Uint8Array([2, 5, 8, 1, 4])
numbers.toString(); // "2,5,8,1,4"
					

JavaScript calls the toString method automatically when a typed array is to be represented as a text value or when an array is referred to in a string concatenation.

兼容性

If a browser doesn't support the TypedArray.prototype.toString() method yet, JavaScript will call the toString 方法为 Object :

var numbers = new Uint8Array([2, 5, 8, 1, 4])
numbers.toString(); // "[object Uint8Array]"
