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>
