Creating HTML code using text-based values

I want to incorporate an image into my HTML code. This method has worked for me:

<img id="image1" src="http://image.jpg" alt=" " width="300" height="300" />

My goal is to substitute the http with a variable so that I can dynamically call the website instead of hardcoding it inline:

<img id="image1" src=URL alt=" " width="300" height="300" />

Is there anyone who can assist me with this?

Answer №1

If you need to change the src attribute of an image dynamically, follow these steps:

// First, select the image element using its ID
var imgElement = document.getElementById("image1");

// Define the new URL for the image
var newImageUrl = 'https://example.com/new-image.jpg';

// Set the new image source
imgElement.setAttribute("src", newImageUrl);
<img id="image1" src="http://old-image.jpg" alt="No Image Found" width="300" height="300" />

Answer №2

Retrieve the image and assign the src attribute:

let targetImage = document.getElementById('image1');
targetImage.src='http://examplewebsite.com/image.jpg';

Answer №3

Make sure to leave the image source unset in your html, but still include the img element within the DOM:

<img id="image1" alt=" " width="300" height="300" />

When it comes to your javascript (which should be placed towards the end of your <body> tag in your html), follow these steps:

let img1 = document.getElementById('image1');

img1.src = "/some/url/or/file-path/here.jpg"
