所以,我对此很陌生,尝试了angularJS和nodeJS大约2天,我陷入了这个错误。
我试图做一个动态的选择选项,我试图使用nodeJS从mysql数据库中回显一个表并将数据扔给有角度的。我已经尝试了很多方法来解决此问题,但是也许我仍然对角度问题还不太了解,所以我还没有解决问题。
我正在使用nodeJS ver。 1.0.0和angularJS版本。 1.7.5。
这是我的代码
controlAll.js
var http = require('http');
var qs = require('querystring');
var fs = require('fs');
var hbs = require('hbs');
var express = require('express');
var bodyParser = require('body-parser');
var route = express();
var mysql = require('mysql');
var konek = mysql.createConnection({
host: "localhost",
user: "root",
password: "",
database: "mahasiswa",
});
konek.connect(function(err){
if(err) throw err;
console.log("udah konek");
});
route.set('view engine', 'hbs');
route.use(bodyParser.json());
route.use(bodyParser.urlencoded({ extended: true }));
route.get('/mahasiswa/add', function(req, res){
res.render("formm");
});
route.get('/jurusan', function(req,res){
konek.query("SELECT * FROM `jurusan`",function(err,jurusan)
{
if (err) throw err;
res.send(JSON.stringify({
jurusan:jurusan
}));
});
});

答案 0 :(得分:0)
您的控制器(或提供服务)应从您的nodejs端点加载jurusan
数据,然后使用它:
app.controller('drpdn', function($scope, $http){
// Simple GET request example:
$http({
method: 'GET',
url: '/jurusan' // USE YOUR NODEJS ENDPOINT TO LOAD DATA
}).then(function(response) {
// this callback will be called asynchronously
// when the response is available
$scope.jurusan = response.data.jurusan;
}, function(response) {
// called asynchronously if an error occurs
// or server returns response with an error status.
});
});
