**To get an element attribute value in JavaScript, you can use the `getAttribute()` method.**
Here’s an example of how you can get the value of the `src` attribute of an image element with the ID “myImage”:
“`js
var imageElement = document.getElementById(“myImage”);
var srcValue = imageElement.getAttribute(“src”);
console.log(srcValue);
“`
In this example, we first get a reference to the image element with the ID “myImage” using `document.getElementById()`. Then, we use the `getAttribute()` method to get the value of the `src` attribute of the image element and log it to the console.
Using the `getAttribute()` method is a versatile way to access the value of any element attribute in JavaScript.
