Question

When you create a post , over in the Left hand side under the vote up and vote down, is a new share on twitter facebook and linkedin.

How do they do that, is it just using javascript ?

Or something far more clever than say:

This : http://www.openjs.com/articles/ajax/target_url_hiding.php

Answer 1

The a tag for the Facebook share does not have an href tag, therefore no URL is displayed when hovering over it by the browser.

They’ll use JavaScript to capture the click on the a tag, and open a popup to complete the action.

Edit:

Psuedo JS code that isn’t x-browser

document.body.addEventListener('click', function (e) {
    if (e.target.className == "fb-share") {
        window.open('http://www.facebook.com');
    }
}, false);
