How to track internal redirect links as well on Google Analytics User Explorer?

问题

I'm trying to see the internal links that our wordpress users clicked on G analytics user explorer section's each user report. The report only shows the wordpress posts they surf but not the internal redirect urls (which are attached to images).

The internal redirect urls are like : www.example.com/download/234234jjk/file.html on download images.

I've used below php and javascript to track clicks:

<?php
    if (is_user_logged_in()) {
        $user = wp_get_current_user();
        $userName = $user->user_login;
    }
?>
<script type="text/javascript">
    function _gaLt(event) {

        /* If GA is blocked or not loaded, or not main|middle|touch click then don't track */
        if (!ga.hasOwnProperty("loaded") || ga.loaded != true || (event.which != 1 && event.which != 2)) {
            return;
        }

        var el = event.srcElement || event.target;

        /* Loop up the DOM tree through parent elements if clicked element is not a link (eg: an image inside a link) */
        while (el && (typeof el.tagName == 'undefined' || el.tagName.toLowerCase() != 'a' || !el.href)) {
            el = el.parentNode;
        }

        /* if a link with valid href has been clicked */
        if (el && el.href) {

            var link = el.href;

            /* Only if it is an external link */
            if (link.indexOf(location.host) == -1 && !link.match(/^javascript\:/i)) {

                /* Is actual target set and not _(self|parent|top)? */
                var target = (el.target && !el.target.match(/^_(self|parent|top)$/i)) ? el.target : false;

                /* Assume a target if Ctrl|shift|meta-click */
                if (event.ctrlKey || event.shiftKey || event.metaKey || event.which == 2) {
                    target = "_blank";
                }

                var hbrun = false; // tracker has not yet run

                /* HitCallback to open link in same window after tracker */
                var hitBack = function() {
                    /* run once only */
                    if (hbrun) return;
                    hbrun = true;
                    window.location.href = link;
                };

                if (target) { /* If target opens a new window then just track */
                    ga(
                        "send", "event", "Outgoing Links", link,
                        document.location.pathname + document.location.search
                    );
                } else { /* Prevent standard click, track then open */
                    event.preventDefault ? event.preventDefault() : event.returnValue = !1;
                    /* send event with callback */
                    ga(
                        "send", "event", "Outgoing Links", link,
                        document.location.pathname + document.location.search, {
                            "hitCallback": hitBack
                        }
                    );

                    /* Run hitCallback again if GA takes longer than 1 second */
                    setTimeout(hitBack, 1000);
                }
            }
        }
    }

    var _w = window;
    /* Use "click" if touchscreen device, else "mousedown" */
    var _gaLtEvt = ("ontouchstart" in _w) ? "click" : "mousedown";
    /* Attach the event to all clicks in the document after page has loaded */
    _w.addEventListener ? _w.addEventListener("load", function() {document.body.addEventListener(_gaLtEvt, _gaLt, !1)}, !1)
        : _w.attachEvent && _w.attachEvent("onload", function() {document.body.attachEvent("on" + _gaLtEvt, _gaLt)});
</script>
<script>
    (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
    (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
    m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
    })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

    ga('create', 'UA-myUAID', 'auto');
    <?php if (isset($userName)) : ?>
        ga('set', 'userId', <?php echo(json_encode($userName)); ?>); // Set the user ID using signed-in user_id.
    <?php endif; ?>
    ga('send', 'pageview');
</script>

However it doesn't log internal clicks. How to include internal links click tracking as well?
