我有这个简单的 app.js 使用 Express JS\NODEJS
var express= require("express");
var path= require("path");
var app= express();
app.use(express.static(__dirname));
var users=[ { userName: "faizan", password: "faizan", email: "mfkj@live.com"},
{ userName: "ali", password: "ali", email: "xyz@live.com"},
{ userName: "hussain", password: "hussain", email: "abc@live.com"},
{ userName: "hassan", password: "hassan", email: "xyz@mail.com"},
];
app.get('/',function(request , response){
response.sendFile(__dirname+ '/index.html');
});
app.get('/frmSignUp', function(request, response){
users.push({
userName: request.query["userName"],
password: request.query["password"],
email: request.query["email"]
});
response.sendFile(__dirname+ '/dashboard.html');
//how can i show my user array items in my dashboard html page?? Question1
});
app.get('/frmSignIn',function(request, response)
{
if(users.contains(request.query["userName"])) //this is invalid
// is there any way available to check userName in array that is this exists?
response.sendFile(__dirname+ '/dashboard.html');
})
var server =app.listen(3010, function(){
console.log("server running on port "+ server.address().port);
})
我在根目录中有索引注册登录和仪表板 HTML 页面。我有上面代码中注释的问题，请让我知道我可以做这些事情吗？
最佳答案
回答您的问题:
使用模板。从现有的 html 中执行此操作的最简单方法可能是使用
ejs(首先在项目根目录中npm install ejs)。示例:app.js:app.set('view engine', 'ejs'); // ... app.get('/frmSignUp', function(request, response) { users.push({ userName: request.query["userName"], password: request.query["password"], email: request.query["email"] }); response.render('dashboard.ejs', { users: users }); });dashboard.ejs:<html> <head> <title>Dashboard</title> </head> <body> <h1>Users</h1> <ul> <% users.forEach(function(user) { %> <li><%= user.userName %></li> <% }); %> </ul> </body> </html>
由于您有一个对象数组，并且要检查
userName字符串，因此您需要手动循环users数组并进行比较用户名。
