问题描述
我这里有一些有角度的 js 代码.
<html lang="zh-cn"><头><script src="Scripts/angular.min.js"></script><身体><div ng-app=""><表格>作者:<input type="text" ng-model="author"><br><br>标题:<input type="text" ng-model="title"><br><br>身体:<input type="author" ng-model="body"><br><br><输入类型=提交"值=提交"></表单>
</html>和带有 MySQL 代码的节点 js 在这里.我能够从这个节点代码将数据传递到 MySQL DB.如何继续使用角度到节点 js?我来自 PHP 背景.我应该能够将数据从 angular js 形式发送到 MySQL 数据库.我可以从这里的节点代码将数据发送到 MySQL 数据库.
var mysql = require('mysql');var connection = mysql.createConnection({主机:'本地主机'，用户:'',密码: ''，数据库:'copedb'});连接.connect();var 应付 = {作者:'XYZXYZ'，title: '测试节点',正文:'节点JS'};var query = connection.query('插入到对应集合中?'，对应，函数(错误，结果){如果(错误){控制台错误(错误)；返回;}控制台错误(结果)；});
解决方案
它可以成为您入门的垫脚石:
索引.html <html lang="zh-cn"><头><script src="Scripts/angular.min.js"></script><script src="Scripts/app.js"></script><body ng-app="myApp"><div ng-controller="myCtrl"><表格>作者:<input type="text" ng-model="author"><br><br>标题:<input type="text" ng-model="title"><br><br>身体:<input type="author" ng-model="body"><br><br><input type="submit" value="Submit" ng-click="submit()"></表单>
Angular 代码 app.js var app = angular.module('myApp', []);app.controller('myCtrl', function($scope) {$scope.submit= function(){var 数据 = $.param({书:JSON.stringify({作者:$scope.author，标题:$scope.title，正文:$scope.body})});$http.post("/api/book/", data).success(function(data, status) {console.log('数据发布成功');})}});
server.js - Nodejs var express = require('express');var mysql = require('mysql');var app = express();var connection = mysql.createConnection({主机:'本地主机'，用户:'',密码: ''，数据库:'copedb'});连接.connect();app.post('/api/book', function(req, res, next){varcop = req.body.params;var query = connection.query('插入到对应集合中?'，对应，函数(错误，结果){如果(错误){控制台错误(错误)；返回 res.send(err);} 别的 {返回 res.send('确定');}});应用程序听(8080)；
I have some angular js code here.
<!DOCTYPE html>
<html lang="en">
<head>
<script src="Scripts/angular.min.js"></script>
<body>
<div ng-app="">
<form>
Author:
<input type="text" ng-model="author">
<br>
<br> Title:
<input type="text" ng-model="title">
<br>
<br> Body:
<input type="author" ng-model="body">
<br>
<br>
<input type="submit" value="Submit">
</form>
</div>
</head>
</body>
</html>
and node js with MySQL code here. I am able to pass data to MySQL DB from this node code. How to go ahead with angular to node js? I am coming from a PHP background. I should be able to send data from angular js form to MySQL database. I am able to send data to MySQL database from node code here.
var mysql = require('mysql');
var connection = mysql.createConnection({
host: 'localhost',
user: '',
password: '',
database: 'copedb'
});
connection.connect();
var cope = {
author: 'XYZXYZ',
title: 'Testing Node',
body: 'Node JS'
};
var query = connection.query('insert into cope set ?', cope, function(err, result) {
if (err) {
console.error(err);
return;
}
console.error(result);
});
解决方案
It can be the stepping stone for you to getting started:
Index.html
<!DOCTYPE html>
<html lang="en">
<head>
<script src="Scripts/angular.min.js"></script>
<script src="Scripts/app.js"></script>
</head>
<body ng-app="myApp">
<div ng-controller="myCtrl">
<form>
Author:
<input type="text" ng-model="author">
<br>
<br> Title:
<input type="text" ng-model="title">
<br>
<br> Body:
<input type="author" ng-model="body">
<br>
<br>
<input type="submit" value="Submit" ng-click="submit()">
</form>
</div>
</body>
Angular code app.js
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.submit= function(){
var data = $.param({
book: JSON.stringify({
author: $scope.author,
title : $scope.title,
body : $scope.body
})
});
$http.post("/api/book/", data).success(function(data, status) {
console.log('Data posted successfully');
})
}
});
server.js - Nodejs
var express = require('express');
var mysql = require('mysql');
var app = express();
var connection = mysql.createConnection({
host: 'localhost',
user: '',
password: '',
database: 'copedb'
});
connection.connect();
app.post('/api/book', function(req, res, next){
var cope = req.body.params;
var query = connection.query('insert into cope set ?', cope, function(err, result) {
if (err) {
console.error(err);
return res.send(err);
} else {
return res.send('Ok');
}
});
app.listen(8080);
