Like updating, deletion takes an object id
, which we pass in the URL to the HTTP DELETE
request.
The doRemove
method gets the object id
from the id
field in the form, and posts a DELETE
message to the server at a URL consisting of the base URL plus the object id
:
function doRemove() { var id = $('#id').val(); if(id == "")'') { alert("Must provide an ID to delete!"); return; } $.ajax({ type: 'DELETE', url: "http://localhost:3000/documents/" + id }) .done(function(result) { $('#json').html(JSON.stringify(result)); var resultHtml = "Deleted"; $('#result').html(resultHtml); }); }
The deletion message handler on the server extracts the ID from the URL and then performs a remove
operation:
exports.deleteDocuments = function(req, res) { var id = new objectId(req.params.id); db.collection('documents', function(err, collection) { collection.remove({'_id':id}, {safe:true}, function(err...
