回答by kennebec

Or use String.

或者使用字符串。

var string = String([1,2,3]);

回答by Flavio Sousa

The join command lets you set the token among the items in the array.

join 命令允许您在数组中的项目之间设置标记。

Ex1:

例1:

function print(str) {
  $("#result").append("<p>" + str + "</p>");  
}

print(["A", "B", "C"].join()); // "A,B,C"
print(["A", "B", "C"].join("-")); // "A-B-C"
print(["A", "B", "C"].join("||")); // "A||B||C"
print(["A", "B", "C"].join("")); // "ABC"
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="result"></div>
