Sharepoint 2013 - Open search result in new window/tab - sharepoint-2013

Question

Ok, so I've been struggling with this problem for a few hours now...
I need to modify the links in the search results, so that they open in a new window/tab.
Specifically it's the search results that links to a "off-site"-hit.
I've created a copy of Item_WebPage.html, but I just can't get it to work.
I guess that there are some kind of async loads that screws it all up.
My js-code is as follows:
var anchors = document.getElementsByClassName('ms-srch-item-link');
for (var i = 0; i < anchors.length; i++) {
anchors[i].setAttribute("target", "_blank");
}
}
However, "anchors" always is "0".
Is there a "sharepoint-document-ready-as-h*ll"-function I can use?
My guess is that my problem is that not all content is loaded into the DOM before I run my code...

A custom display template is a good way of changing the behavior of the search results. I've used JQuery code to make sure that external links always load in a new window :
<script type="text/javascript">
if (window.jQuery) {
$(window).load(function () {
// Open external links in a new tab
var url = '://' + window.location.hostname;
// get the current website name, and i add :// to make sure we're looking at the right name //
url = url.toLowerCase(); // lowercase everything to compare apples to apples
$("a").each(function () {
var link = this; // assign the link object to another variable for easier managability
var linkHref = link.href.toLowerCase(); // lower case it
if (linkHref.indexOf(url) < 0 && linkHref.indexOf('javascript:') < 0) { // check to see if this A object has this domain in it and make sure it's not a javascript call
link.target = '_blank'; // change the target to be in the new window
} if (linkHref.indexOf('.pdf') > 0) { // check to see if this is a PDF
link.target = '_blank'; // change the target to be in the new window
$(link).removeAttr("onclick"); //remove the SP click event
} if (linkHref.indexOf('/forms/') > 0 && linkHref.indexOf(').aspx') > 0) { //check for links in the forms library
link.target = '_blank'; // change the target to be in the new window
$(link).removeAttr("onclick"); //remove the SP click event
}
});
});
}
</script>

It's way too long and you may have resolved it.
I was looking for the same and added - target="_blank" to the anchor tag in a custom display template

In SharePoint online, this worked perfectly for me, applies to all results though.
Using SharePoint Designer, update the Item_CommonItem_Body.html Display Template from within _catalogs/masterpage/display templates/search.
Search for below line :
var titleHtml = String.format('<a clicktype="{0}" id="{1}" href="{2}" class="ms-srch-item-link" title="{3}" onfocus="{4}" {5} >{6}</a>',
and replace it with :
var titleHtml = String.format('<a clicktype="{0}" id="{1}" href="{2}" class="ms-srch-item-link" title="{3}" onfocus="{4}" {5} target="_blank">{6}</a>',
Save the change and, from the browser master page library, publish a major version. When you search now the results should open in new tabs although you may need to load the page cache again (CTRL+F5).
