Dom-to-image is a library which can turn arbitrary DOM node into a vector (SVG) or raster (PNG or JPEG) image, written in JavaScript. $('#myImage').attr('src', 'img/new-image.jpg'). To achieve this task, we are going to depend of the dom-to-image Javascript library. If you need to do something after the new image has loaded, then you can attach jQuery’s load() method to our example above: //Change the img property and use load() to figure out when Determining when the new image is loaded.

In the code above, we referenced the image by its ID and then used jQuery’s attr() method to set a new value for its src attribute.

If you’re already using the jQuery library and you would like to keep your code consistent, you can use the following method: //Change the img property using jQuery's attr method On Mar 2, 12:35 am, wrote: Not sure about ID, but if you use the NAME attribute. Let's create a variable image with createElement ('img'): var img document.createElement('img').

This will force the browser to load our new image. After retrieving the img, we were able to modify its src attribute and assign a new URL.We passed “myImage” in as the parameter because that is the ID of our image. We retrieved the img element from our HTML DOM by using the method document.getElementById().In this case, we have broken the process up into two steps: Set the src property of our element to the new image URL Var img = document.getElementById('myImage') If you run the snippet above, you will see that the src attribute of our image element is replaced by our JavaScript code.Ī more verbose example for those of you who want to understand what is going on here: //Get our img element by using document.getElementById Only send the origin of the document as the referrer in all cases.

The URL is sent as a referrer when the protocol security level stays the same (e.g.HTTPHTTP, HTTPSHTTPS), but isn't sent to a less secure destination (e.g. No referrer information is sent along with requests. Modify the src attribute of the image with the ID 'myImage'ĭocument.getElementById('myImage').src = 'img/new-image.jpg' The Referer header will be omitted entirely. Instead, you can just use vanilla JavaScript, which tends to be faster. If you’re not already using jQuery, then there is no sense in including the library just to manipulate the src attribute.

In this post, I will show you how to accomplish this using both regular JavaScript and jQuery.Ĭhanging the src attribute using regular JavaScript. Therefore, by setting a new src, we can dynamically change the image in question. The src attribute specifies the URL of an image. This is a tutorial on how to change the “src” attribute of an image using JavaScript.
