Question

我是Javascript的新手。我试图让我的数组按字母顺序打印，但我尝试过的所有方法似乎都不起作用。例如array.sort（）。请注意，console.log不会因某些我不知道的原因打印。这是我的代码，

<!DOCTYPE html>
<html>
<body>   
<p id="products"></p>
<script>                            
var products =    ["Printer","Tablet","Router","Monitor","Keyboard","Mouse","Webcam","Hard Drive"];
document.getElementById("products").innerHTML = products; 
array.sort("products");
</script>
</body>

非常感谢泰德

Answer 1

您需要在您的数组中调用.sort()变量products。 Array Sort

var products = ["Printer","Tablet","Router","Monitor","Keyboard","Mouse","Webcam","Hard Drive"];

products.sort(); // add this line

document.getElementById("products").innerHTML = products;

<p id="products"></p>

Answer 2

试试这个 document.getElementById("products").innerHTML = products.sort();

Answer 3

sort（）是一种扩展方法，您不需要将参数传递给。您只需要使用函数名称调用数组名称。您可以查看有关sort（）函数here的更多信息。

var products =    ["Printer","Tablet","Router","Monitor","Keyboard","Mouse","Webcam","Hard Drive"];
products.sort();
document.getElementById("products").innerHTML = products;

＆＃13;

<p id="products"></p>

＆＃13;

Answer 4

必须是products.sort();。 Array具有用于排序的内置功能。</ p>

Answer 5

var products = ["Printer","Tablet","Router","Monitor","Keyboard","Mouse","Webcam","Hard Drive"];

products.sort(); // add this line

document.getElementById("products").innerHTML = products;

<p id="products"></p>
