"Trouble with jQuery: Selecting an image to change isn't

Can someone help me figure out why my simple image change on a dropdown isn't working correctly?

You can find the code on this Jsfiddle.

Thank you for any assistance!

$("#display_avatar").change(function(){
    $("img[name=preview]").attr("src", $("option").attr("imagePath"));
    event.preventDefault();
});

<img src="http://placehold.it/100/0000FF/000000" name="preview" /><br /><br />

<select class="form-control" name="display_avatar" id="display_avatar">
    <option value="1" imagePath="http://placehold.it/100/cccccc/000000">First</option>
    <option value="2"imagePath="http://placehold.it/100/ghghgh/000000">Second</option>
    <option value="3"imagePath="http://placehold.it/100/5fgrty/000000">Third</option>
    <option value="4"imagePath="http://placehold.it/100/ff0000/000000">Fourth</option>
</select>

Answer №1

If you want to retrieve the value from the first option only, use this code:

$("option").attr("imagePath")

For an alternative method, try the following code snippet instead:

this.selectedOptions[0].getAttribute("imagePath")

You can view the updated demonstration here: http://jsfiddle.net/979vbv0j/2/

Answer №2

$("option") retrieves all option elements on the current page. In order to achieve your desired outcome, you should implement the following code:

$("#display_avatar").change(function(){
    $("img[name=preview]").attr("src", $(this).find("option:selected").attr("imagePath"));
    event.preventDefault();
});
