下面的代码演示了JS中如何通过数组对象的join方法将数组元素连接成一个字符串输出
<!DOCTYPE html>
<html>
<body>
<p id="demo">
Click the button to join the array elements into a string.
</p>
<button onclick="myFunction()">Try it</button>
<script>
function myFunction()
{
var fruits = ["Banana","Orange","Apple","Mango"];
var x=document.getElementById("demo");
x.innerHTML=fruits.join();
}
</script>
</body>
</html>
运行结果如下：
Banana,Orange,Apple,Mango
