如何创建一个图像URL数组,将其附加到现有数组中,并使用jQuery获取页面以加载图像?

我正在尝试将图像添加到我的随机数组中。基本上,这个随机生成器告诉你应该看哪部电影,我想知道如何在标题下添加移动的图像。我认为最好的方法可能是使用图像URL创建第二个数组,并使用+和括号将其附加到现有数组中。我只是不知道如何让脚本加载图像。这是我的密码笔: https://codepen.io/McComb/pen/qVPOQO

JQuery

 function GetValue()
{
var myarray= new Array("The Santa Claus", "Just Friends","Home Alone", "Home 
Alone 2","Serendipity","Love Actually","Elf","Christmas Vacation","A 
Christmas Story","The Grinch","Jingle All the Way","Rudolph the Red-Nosed 
Reindeer","Ernest Saves Christmas","Frosty the Snowman","The Muppet 
Christmas Carol","The Nightmare Before Christmas","Jesus of Nazareth 
1977","Bad Santa");
var random = myarray[Math.floor(Math.random() * myarray.length)];
//alert(random);
document.getElementById("message").innerHTML=random;
}

实现所需功能的最简单方法是保存对象,而不是数组中的字符串。这样,您可以创建具有 title 字段和an imageUrl 类似这样的字段:

var myarray= new Array(
    {
        title: "The Santa Claus",
        imageUrl: "https://upload.wikimedia.org/wikipedia/en/thumb/e/e7/Video-x-generic.svg/90px-Video-x-generic.svg.png"
    }, 
    {
        title: "Random Movie",
        imageUrl: "https://upload.wikimedia.org/wikipedia/commons/thumb/a/ad/BolexH16.jpg/220px-BolexH16.jpg"
    }, 
    // you can add as many comma-separated objects as you want
);

添加 img 元素并为其指定id picture . 在JS中,您可以这样设置电影的标题和图像:

document.getElementById("message").innerHTML=random.title;

// the element with id picture is an image element
document.getElementById("picture").src = random.imageUrl;
