git cherry-pick -m 1 <merge request commit hash 1>
git cherry-pick -m 1 <merge request commit hash 2>
...
git cherry-pick -m 1 <merge request commit hash N>

I'd suggest using the stopPropagation() method as shown in the modified fiddle:

Fiddle

$('body').click(function() {
    $(".popup").hide();
});

$('.popup').click(function(e) {
    e.stopPropagation();
});

That way you can hide the popup when you click on the body, without having to add an extra if, and when you click on the popup, the event…

In case it helps someone else who lands here like I did, after a bit of researching I found out that using ISO8601 format also works:

git log --since="2014-02-12T16:36:00-07:00"

This will give you precision down to the second. Note: you can also use:

git log --after="2014-02-12T16:36:00-07:00"
git log --before="2014-02-12T16:36:00-07:00"

Off the top of my head in jQuery:

<script type="text/javascript">
$('.numbers').each(function() {
    $(this).html(
        $(this).html().substr(0, $(this).html().length-2)
          + "<span style='color: #3399ff'>"
          + $(this).html().substr(-2)
          + "</span>");
});
</script>

Here's a fiddle to demonstrate it. I'm sorry it's not plain JavaScript, but I'm sure one of the folks here can offer a native solution…

Shortest, but not best performance (see update bellow) solution for es6 :

function unique(array, propertyName) {
   return array.filter((e, i) => array.findIndex(a => a[propertyName] === e[propertyName]) === i);
