Uncaught ReferenceError: variable is not defined on onclick function Javascript

Question

Today , i have been read all the topic about this but couldn't come up with a solution that's why i am opening this topic.

This is my function which creates the view and i am trying to have a onclick function which should directs to other javascript function where i change the textbox value.

<script type="text/javascript">
    $('#submitbtnamazon')
            .click(function(evt) {
                        var x = document.getElementById("term").value;

                        if (x == null || x == "" || x == "Enter Search Term") {
                            alert("Please, Enter The Search Term");
                            return false;
                        }
                        listItems = $('#trackList').find('ul').remove();
                        var searchTerm = $("#term").val();
                        var url = "clientid=Shazam&field-keywords="
                                + searchTerm
                                + "&type=TRACK&pagenumber=1&ie=UTF8";       

    jsRoutes.controllers.AmazonSearchController.amazonSearch(url)
                        .ajax({
                            success : function(xml) {
                                $('#trackList')
                                    .append('<ul data-role="listview"></ul>');
                                    listItems = $('#trackList').find('ul');
                                    html = ''

                                 tracks = xml.getElementsByTagName("track");
                                for(var i = 0; i < tracks.length; i++) {
                                    var track = tracks[i];
                                    var titles = track.getElementsByTagName("title");
                                    var artists = track.getElementsByTagName("creator");
                                    var albums =    track.getElementsByTagName("album");

                                                                .getAttribute("rel");

                                                        if (name == "http://www.amazon.com/dmusic/ASIN") {

                                                $("#track").html(html);
                                                $("#track").dialog({
                                                    height : 'auto',
                                                    width : 'auto',
                                                    title : "Search Results"
                                                });
                                                // Need to refresh list after AJAX call
                                                $('#trackList ul').listview(
                                                        "refresh");
                                            }
                                        });
                    });
</script>

This is my other function where i change the textbox value. it works actually with other values e.g. when i give hardcoded string value. I can see the value in the console but for some reason it gives me the error like : here the string starts with B is AsinId where i take from amazon. I am definitely in need of help because i am totally stucked.

Uncaught ReferenceError: B00BMQRILU is not defined 62594001:1 onclick

<script type="text/javascript">

    function someFunction(var1) {
        tracktextbox = document.getElementsByName("trackId");
        for (var i = 0; i < tracktextbox.length; i++) {
            tracktextbox[i].value = var1;
        }
        $('#track').dialog('close');
    }

</script>

Answer 1

The problem is '<h6><a href="#" onclick="someFunction('+trackId+ ')">', from the error it is clear that trackId is a string value, so you need to enclose it within "" or ''. So try

'<h6><a href="#" onclick="someFunction(\'' + trackId + '\')">'
