将每个数字转换为字符串并将它们连接起来

Question

I have javascript array of integers:

[1,3,2,9,5,44]

I need to convert each number to string and concatenate them:

"1,3,2,9,5,44"

How can I implement it ?

Answer 1

使用数组的join方法：

[1,3,2,9,5,44].join(',');

Answer 2

 var array = [1,3,2,9,5,44];
    var result = array.join(",");

Answer 3

您可以使用连接方法： https : //developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Array/join

yourArray.join(",")

Answer 4

You could use JavaScript Array join() method like this:

var arrayOfIntegers = [1,3,2,9,5,44];
var concatenated = arrayOfIntegers.join();

Note that the default separator for this method is comma, so the result would be

1,3,2,9,5,44

If you want to have the result string some other way, you could pass the separator as an argument to this method, eg

var arrayOfIntegers = [1,3,2,9,5,44];
var concatenated = arrayOfIntegers.join(" , ");

would produce this string

1 , 3 , 2 , 9 , 5 , 44
