    put id attribute on anchor element

    <a id="link2">

    set href attribute on page load event:

    (function() {
    var scrt_var = 10;
    var strLink = "2.html&Key=" + scrt_var;
    document.getElementById("link2").setAttribute("href",strLink);
})();

    You can also use an express framework

    app.get("/:id",function(req,res)
{
  var id = req.params.id;
  res.render("home.ejs",{identity : id});
});

    Express file, which receives a JS variable identity from node.js

    <a href = "/any_route/<%=identity%> includes identity JS variable into your href without a trouble enter

    JAVASCRIPT CODE:

    <script>

    function getUrlVars()
{
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
    for(var i = 0; i < hashes.length; i++)
    {
        hash = hashes[i].split('=');
        vars.push(hash[0]);
        vars[hash[0]] = hash[1];
    }
    return vars;
}

var user = getUrlVars()["user"];
var pass = getUrlVars()["pass"];
var sub  = getUrlVars()["sub"];
</script>

<script>
    var myApp = angular.module('myApp',[]);

myApp.controller('dropdownCtrl', ['$scope','$window','$http', function($scope, $window, $http) {

 $http.get('http://dummy.com/app/chapter.php?user='+user+'&pass='+pass)

     .then(function (response) {$scope.names = response.data.admin;});
    $scope.names = [];

        $http.get('http://dummy.com/app/chapter.php?user='+user+'&pass='+pass+'&sub='+sub)

            .then(function (response) {$scope.chapter = response.data.chp;});
           $scope.chapter = [];

};


}]);
    </script>

    HTML:

    <div ng-controller="dropdownCtrl">
<div ng-repeat="a in chapter">
<a href="topic.html?ch={{a.chapter}}" onClick="location.href=this.href+'&user='+user+'&pass='+pass+'&sub='+sub;return false;">{{a.chapter}}</a>
</div>

    <html>

<script language="javascript" type="text/javascript">
var scrt_var = 10; 
openPage = function() {
location.href = "2.html?Key="+scrt_var;
}
</script>

 this is a <a href ="javascript:openPage()">Link  </a>
</html>

    If you want it to be dynamic, so that the value of the variable at the time of the click is used, do the following:

    <script language="javascript" type="text/javascript">
var scrt_var = 10; 
</script>
<a href="2.html" onclick="location.href=this.href+'?key='+scrt_var;return false;">Link</a>

    Of course, that's the quick and dirty solution. You should really have a script that after DOM load adds an onclick handler to all relevant <a> elements.

    Alternatively you could just use a document.write:

    <script type="text\javascript">
var loc = "http://";
document.write('<a href="' + loc + '">Link text</a>');
</script>
