Question: How can one get the alt value of an image using jQuery?


To get the alt value of an image using jQuery, you need to use the .attr() function. This function gets the attribute value for only the first element in the matched set. It returns undefined for values of undefined elements.

Here's a basic example:

$(document).ready(function(){ var altValue = $('img').attr('alt'); console.log(altValue); });

In this example, $('img') selects all the image elements on the page. The .attr('alt') method then gets the alt attribute value of the first image found. The value is stored in the altValue variable and printed out to the console with console.log(altValue).

Please note: If there are multiple images and you want to get alt text from a specific image, you should give that image an ID or class and select it accordingly.

For instance, if you have an image with an ID of 'myImage':

<img id="myImage" src="image.jpg" alt="My Image Alt Text">

You could then get the alt text with the following jQuery code:

$(document).ready(function(){ var altValue = $('#myImage').attr('alt'); console.log(altValue); });

In this second example, $('#myImage') selects the image element with the ID of 'myImage'. The rest of the code functions just as before, getting the alt attribute value and logging it to the console.

Remember to link the jQuery library in your HTML file (usually in the <head> section), like so:

<script src=""></script>
