我们可以通过JS数组的splice方法在执行的位置插入新的元素,非常简单
<!DOCTYPE html> <html> <body> <p id="demo">Click the button to add elements to the array.</p> <button onclick="myFunction()">Try it</button> <script> function myFunction() { var fruits = ["Banana", "Orange", "Apple", "Mango"]; fruits.splice(2,0,"Lemon","Kiwi"); var x=document.getElementById("demo"); x.innerHTML=fruits; } </script> </body> </html>
上面的代码执行后输出如下结果
Banana,Orange,Lemon,Kiwi,Apple,Mango
