Displaying a single document from a mongo database? - mongodb

Question

I use ejs to display the information but I am having trouble displaying only one document. I would like to display one document until user clicks the next button.
View:
<div>
<h1>This is the movie page</h1>
<ul>
<% for(var i =0; i < movies.length; i ++) {%>
<li>
<span style="font-weight: bold">Title:</span> <%= movies[i].DVD_Title %>
</li>
<li>
<span style="font-weight: bold">Studio:</span> <%= movies[i].Studio %>
</li>
<li>
<span style="font-weight: bold">Genre:</span> <%= movies[i].Genre %>
</li>
<li>
<span style="font-weight: bold">Year:</span> <%= movies[i].Year %>
</li>
<br>
<% } %>
<button type="button" id="prev">Prev </button>
<button type="button" id="next">Next</button>
</ul>
</div>
Controller:
var express = require('express');
var router = express.Router();
var moviesModel = require("../models/movies");
/* GET /movies/ listing. */
router.get('/', function(req, res, next) {
moviesModel.find({}).where('Price').gt(10000).exec(function(err,movies){
if(err) throw err;
res.render('movies', {movies:movies});
});
});
module.exports = router;

Since the mongodb query data is returned to the view as an json objects I cannot increment it. I have to push it to its own array and increment that.
Here is my new view:
<div>
<h1>This is the movie page</h1>
<ul>
<% var movieArray = new Array();
for(var i =0; i < movies.length; i ++) {
movieArray.push(movies[i]);
}
var x = 0;
%>
<li>
<span style="font-weight: bold">Title:</span> <%= movieArray[x].DVD_Title %>
</li>
<li>
<span style="font-weight: bold">Studio:</span> <%= movieArray[x].Studio %>
</li>
<li>
<span style="font-weight: bold">Genre:</span> <%= movieArray[x].Genre %>
</li>
<li>
<span style="font-weight: bold">Year:</span> <%= movieArray[x].Year %>
</li>
<br>
<h1><%= movieArray.length %></h1>
<button type="button" id="prev" onClick="prev_movie">Prev </button>
<button type="button" id="next" onClick="next_movie">Next</button>
</ul>
</div>
Once Prev or Next is pushed the x value will decrease or increase unless user reaches -1 or array.length.
