I had the need to programmatically add an image to the , in other words to an HTML page, dynamically.

我需要以编程方式动态地将图像添加到 ，即添加到HTML页面。

To do that, I created an img element using the createElement method of the Document object:

为此，我使用Document对象的createElement方法创建了一个img元素：

const image = document.createElement('img')

Then I set the src attribute of the image:

然后设置图像的src属性：

image.src  = '/picture.png'

(You can use a relative or an absolute URL, just as you’d use in a normal HTML img tag)

(您可以使用相对或绝对URL，就像在普通HTML img标签中使用的一样)

Then I identified the container I wanted to append the image to, and I called the appendChild() method on it:

然后，我确定了要将图像附加到的容器，并在其上调用了appendChild()方法：

document.querySelector('.container').appendChild(image)
