[Solved] What does this line of Jquery do?

by


jQuery uses CSS selectors. a[^="https://stackoverflow.com/"] will select all <a> whose href attribute starts with / which are children of whatever the this is.

See it in action:

$("ul").each(function () {
  $(this).find("a[href^="https://stackoverflow.com/"]").addClass("selected");
});
.selected {
   background-color: lime;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul>
    <li><a href="http://www.google.com">Will not be selected</a></li>
    <li><a href="http://stackoverflow.com/example">Will be selected</a></li> 
</ul>

<ul>
    <li><a href="http://stackoverflow.com/example">Yep</a></li> 
    <li><a href="http://www.google.com">Nope</a></li>
</ul>
