JS数组带有一个slice方法,可以获取数组的指定部分,下面的代码获取数组中的第二个和第三个元素
<!DOCTYPE html> <html> <body> <p id="demo">Click the button to extract the second and the third elements from the array.</p> <button onclick="myFunction()">Try it</button> <script> function myFunction() { var fruits = ["Banana", "Orange", "Lemon", "Apple", "Mango"]; var citrus = fruits.slice(1,3); var x=document.getElementById("demo"); x.innerHTML=citrus; } </script> </body> </html>
上面的代码输出
Orange,Lemon
