我遇到了在我的快速應用程序內實施更新的問題。 http://localhost:3000/update2?buyerID=2299 當我輸入上面顯示的鏈接，它將我帶到一個表格，但它的空... 我想這個表格填充與買方ID文件相關的當前值。節點JS Express更新問題
任何人都可以看到我要去哪裏錯了嗎？
感謝

當您在瀏覽器中查看空表單的源代碼時，您會看到什麼？您在節點控制檯中是否收到錯誤？ –
即時通訊沒有得到任何錯誤，我只是希望字段填寫與該買家ID有關的數據的形式 –
我從來沒有使用ejs，但我敢肯定你a）需要至少把值包含引號中的空格和b）刪除斜槓。另外，你認爲什麼是源代碼？它是否包含「value =」？如果是這樣，在那之後插入了什麼？另外，你將'qs：req.query'傳遞給渲染器。你不應該通過'qs：result'嗎？ –
