删除请求（MongoDB、express、handlebars）

Question

I am having trouble making a delete request in my application. I have a database of reviews, which I alter with my application.

I am trying to make a function that will delete a document from my database and redirect the user to another page.

Here is my handelbars view(i am trying to set it up so if a user clicks on the link, it will excecute the delete method):

<h1>{{rev.title}}</h1>
<h2>{{rev.snippet}}</h2>
<p>{{rev.body}}</p>

<a class ="rem" data-method="delete" href="/reviews/{{this.id}}" >Delete</a>
 //some javascript??!!

This is my router in the routers file:

router.delete('/:id',reviewController.review_delete);

This is my method in the controller file:

const review_delete =  (req, res) => {
    const id = req.params._id;
    mySchemas.reviews.findByIdAndRemove(id, function (err){
        if(err) {
            res.send(err);
        } else {
            res.redirect("./reviews");
        }
    });

}

I've tried multiple things, but i do not yet understand how to actually make it so that the user can delete things. Thanks for your help.

Instead of doing this

 <a class ="rem" data-method="delete" href="/reviews/{{this.id}}" >Delete</a>

Do this

<a class ="rem" href="/reviews/{{this.id}}" onclick="delete({{this.id}})" >Delete</a>

 function delete(id) {
   const xhttp = new XMLHttpRequest();
   xhttp.onreadystatechange = function() {
     // some code
   };
   xhttp.open("DELETE", `<your-server-host>/reviews/${id}`, true);
   xhttp.send();
 
  }
