Question

因此，当我使用＆＃34; gameName＆＃34;点击按钮时，我希望能够删除MongoDB中的特定项目。值。当我这样做时，我不断收到错误404＆＃39;无法删除＆＃39;。我在这做错了什么？谢谢。

以下是请求：

function deleteGame() {
$('#js-games').on('click', '.delete', function(event) {
    event.preventDefault();
    console.log('delete button works')
    var id = $(this).parent().data('id');
    console.log(id);
$.ajax({
    type: 'DELETE',
    dataType: 'json',
    contentType: 'application/json; charset=utf-8',
    url: '/favorites' + '/' + id,
    success: getYourGames(),
})
    var gone = 'Your time was deleted!';
    $('.js-type-game').html(gone);
    setTimeout(function() {
        $('.js-type-game').fadeOut(gone).html('').fadeIn();
        }, 2000);
})

}

这是router.delete：

router.delete('/gameName', (req, res) => {
favorite.delete(req.params.gameName);
console.log(`Deleting game \`${req.params.gameName}\``);
res.status(204).end();
});

Answer 1

您不小心定义了明确的/gameName路线。要定义参数，您需要使用冒号，即：

router.delete('/:gameName', (req, res) => { // with colon (:)
    favorite.delete(req.params.gameName); // req.params.gameName is now correct
    console.log(`Deleting game \`${req.params.gameName}\``);
    res.status(204).end();
});

试图在Ajax中删除MongoDB文档继续获取错误404＆＃39;无法删除＆＃39;
