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
