getSelector.js provides a simple function to get the shortest possible CSS selector path of an element.
Here's some HTML:
<!DOCTYPE html>
<div id="container">
<ul>
<li>1</li>
<li>2</li><!-- second 'li' here -->
<li>3</li>
</ul>
</div>
... and for some reason, your JavaScript code has a variable reference to the second <li> tag (let's call it the el variable). You can get the CSS selector path to it by calling the getSelector function:
getSelector(el); // Returns "li:nth-child(2)"
It's that simple.
getSelector.js should work on browsers that support querySelector, getElementsByClassName and String.trim, which probably includes:
- Chrome 4+
- Firefox 3.5+
- Internet Explorer 9+
- Opera 10.5+
- Safari 5+
But, currently it's only tested on:
- Chrome 14+
- Firefox 7+
