How to delete the multiple rows based on checkbox conditon - node.js

Question

I am new to node.js. I am created small example, now I want to delete multiple rows based on checkbox condition. I have one table of checkboxes as last column. I want delete checked checkbox rows when click on button.
Jade code is
<section class="get">
<h3>Get Data</h3>
LOAD DATA
<div>
<table>
{{# each items }}
<article class="item">
<tr>
<td>{{ this.title }}</td>
<td>{{ this.content }}</td>
<td>{{ this.author }}</td>
<td>{{ this._id }}</td>
<form action="/check" method="post">
<td><input type="checkbox" id="chk" name="chk" ></td>
</article>
</tr>
{{/each}}
<button>check</button>
</form>
</table>
</td>
</section>
Back end code is
router.get('/get-data', function(req, res, next) {
var resultArray = [];
mongo.connect(url, function(err, db) {
assert.equal(null, err);
var cursor = db.collection('user-data').find();
cursor.forEach(function(doc, err) {
assert.equal(null, err);
resultArray.push(doc);
}, function() {
db.close();
res.render('index', {items: resultArray});
});
});
});`
router.post('/check', function(req, res, next) {
// var id = req.body.id;
console.log("check value");
console.log(req.body.chk);
req.body.chk=Boolean(req.body.chk);
for(i=0; i<req.body.chk;i++){
if(req.body.chk==true){
res.redirect('/');
}
else{
res.send("checkbox is not checked");
}
}
});
