数组tostring方法_数组toString（）方法以及JavaScript中的示例
數(shù)組tostring方法
JavaScript toString()方法 (JavaScript toString() method)
toString() method is used to convert an array to the string. It is called with the array name and returns the string containing array elements with comma separated.
toString()方法用于將數(shù)組轉(zhuǎn)換為字符串。 使用數(shù)組名稱調(diào)用它，并返回包含以逗號(hào)分隔的數(shù)組元素的字符串。
Syntax:
句法：
array.toString();Parameters: None
參數(shù)：無
Return value: A string containing array elements
返回值：包含數(shù)組元素的字符串
Example:
例：
Input:var arr = [10, 20, 30, 40, 50];Function call:var str = arr.toString(); Output:str = "10,20,30,40,50"JavaScript code to convert array’s elements to the string using Array.toString() method
JavaScript代碼使用Array.toString()方法將數(shù)組的元素轉(zhuǎn)換為字符串
<html> <head> <title>JavaScipt Example</title> </head><body><script>var arr1 = ["Manju", "Amit", "Abhi", "Radib"];var arr2 = [10, 20, 30, 40, 50];var arr3 = [-10, -20, 0, 10, 20];var str1 = arr1.toString();var str2 = arr2.toString();var str3 = arr3.toString();document.write("str1: " + str1 + "<br>");document.write("str2: " + str2 + "<br>");document.write("str3: " + str3 + "<br>");document.write("printing the types of the objects...<br>");document.write("type of arr1: " + typeof(arr1) + "<br>");document.write("type of arr2: " + typeof(arr2) + "<br>");document.write("type of arr3: " + typeof(arr3) + "<br>");document.write("type of str1: " + typeof(str1) + "<br>");document.write("type of str2: " + typeof(str2) + "<br>");document.write("type of str3: " + typeof(str3) + "<br>");</script> </body> </html>Output
