获取从HTML页面发布的数据到Node.Js / Express？
获取从HTML页面发布的数据到Node.Js / Express？
提问于 2014-08-14 09:03:17
我是node.js / express的新手，我有一个问题。我找了好几个小时。
我正试图为我的基本博客制作一个管理面板，我需要发布：
title & content从HTML到my panel.js
以下是我尝试过的：
从HTML页面发布数据，它的工作原理是：
$(document).ready(function() {
$('#but').click(function(e) {
e.preventDefault();
var title = document.getElementById('title');
$.ajax({
type: "POST",
url: "/panel/save",
data: title.value,
dataType: "json"
});
});
});和panel.js
var express = require('express');
var router = express.Router();
var app = express();
router.get('/', function(req, res) {
res.render('panel_html');
});
/* mysql things */
router.get('/save/', function(req, res) {
var t = req.params.title;
console.log("title :"+t);
});
module.exports = router;错误报告：

首先，当您将title变量传递到ajax调用中时，请确保将它放在一个对象文本中，从而为它命名：
$.ajax({
type: "POST",
url: "/panel/save",
data: { title: title.value },
dataType: "json"
});接下来，将您的router.get更改为router.post，以便它可以接受路由。接下来，您应该通过req.body访问您的后期数据。只需确保在此路由声明之前，您正在应用程序中的某个地方useing express的body-parser。
router.post('/save/', function(req, res) {
var t = req.body.title;
console.log("title :"+t);
