Highlight a sentence on hover; change class on click

Highlight a sentence on hover; change class on click

Hi, I'm trying to figure this out with jQuery:

I have a few paragraphs of text kind of like this:

<p class="original" id="paragraph_1">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Fusce ut metus augue, vitae malesuada massa. Vestibulum nec lectus urna, vehicula porta leo. Fusce dui nunc, scelerisque at molestie ut, ultricies eu purus. Duis tristique placerat rhoncus. Aliquam rhoncus lacus justo. Morbi ultricies egestas orci eget fermentum. Proin sapien sem, suscipit vel semper in, tincidunt id enim. </p>

<p class="text" id="paragraph_2">Maecenas nisl ipsum, faucibus sed pulvinar a, tristique sed magna. Sed dui erat, tempor ut rhoncus sagittis, lacinia quis lorem. Quisque feugiat, ipsum nec varius elementum, est nunc lacinia mi, mollis convallis lorem ipsum at erat. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas.</p>


and I have a couple of classes, like so:
.highlight {
background-color: #ccc;
}

.strikethrough {
text-decoration: line-through;
}


What I want to do is apply the .highlight class to a sentence (not the entire paragraph) on hover, and apply the .strikethrough class to a sentence on click. It's easy to find a sentence using regex, but I don't know how to add/remove a span to just that particular sentence that is being hovered over.

I know I could programatically wrap each sentence in <span>...</span> tags on the backend, but I was hoping there was a better solution.

Thanks for your help!
