html - jQuery: Easiest way to wrap an image tag with an A anchor tag

Question

This is a simplified version of my problem.

I have two buttons, and one image. The image code is something like this

<img class="onoff" src="image.jpg">

When I press button one I want the image to be wrapped in an A tag, like

<a href="link.html">
<img class="onoff" src="image.jpg">
</a>

And when I press the other button, the A tags should be removed.

What's the easiest way of doing this with jQuery?

Answer 1

you have already many answers, but (at least before I started writing) none of them will correctly work.

They do not take into account that you should not wrap the <img> with multiple <a> tags. Furthermore, do not try to unwrap it if it is not wrapped! You would destroy your DOM.

This code simple does a verification before wrapping or unwrapping:

$(function(){
    var wrapped = false;
    var original = $(".onoff");

    $("#button1").click(function(){
        if (!wrapped) {
            wrapped = true;
            $(".onoff").wrap("<a href="link.html"></a>");
        }
    });

    $("#button2").click(function(){
        if (wrapped) {
            wrapped = false;
            $(".onoff").parent().replaceWith(original);
        }
    });
});

Good luck!
