下面的代碼演示了JS數組通過push方法添加一個元素到數組末尾
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 <!DOCTYPE html> <html> <body> <p id="demo"> Click the button to add a new element to the array. </p> <button onclick="myFunction()">Try it</button> <script> var fruits = ["Banana","Orange","Apple","Mango"]; function myFunction() { fruits.push("jb51.net") var x=document.getElementById("demo"); x.innerHTML=fruits; } </script> </body> </html>上面的代碼執行後輸出如下結果
Banana,Orange,Apple,Mango,jb51.net
