I'm taking html content out of my database and displaying it on a page.

Unfortunately these pages often have unclosed html tags and cause problems later when the page is rendered.

I was wondering if there is a JavaScript implementation of something like tidy or htmlpurifier.

Basically some software which can preferably close html tags in a string.

Edit: I'm not in a browser environment (node.js)

As you tagged your question with node.js:

npm install tidy

Something like this could work:

function tidy(htmldata) {
    var d = document.createElement('div');
    d.innerHTML = htmldata;
    return d.innerHTML;
}
