Question

我想将我的products数组传递给html页面。

app.get("/", function(req, res){
    res.render(__dirname+ "/product.html",{data: Product_Array_fromDatabase});
})

在HTML页面的客户端，我试图查看/将循环它

<script type="text/javascript">
    var data = JSON.stringify(data);
   alert(data) // Says Undefined
</script>

我没有获得数据的价值？有什么帮助吗？

我做了ejs渲染数据并使用jquery ajax将数据发送到页面并提醒它可能对你有用

<强> hello.js

var express = require('express');
var app = express();

var engine = require('ejs-locals');

app.engine('ejs', engine);
app.set('view engine', 'ejs');
app.set('views', __dirname + '/views');


app.get('/', function(req, res){ 
res.render('index',{user:"John Smith"}) 
 });

app.get('/helo', function(req, res){
  res.send({'data':'hello'});
});


var server = app.listen(3000, function () {

  var host = server.address().address;
  var port = server.address().port;

  console.log('Example app listening at http://%s:%s', host, port);

});

<强> index.ejs 在名为views --- path appname / views / index.ejs

的目录中

<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
<script>
$(document).ready(function(){
    $("button").click(function(){
        $.get("/helo", function(data, status){
            console.log(data);
            var result = data
            alert(result['data'])
        });
    });
});
</script>
</head>
<body>
welcome <%= user%><br>
<button>Send an HTTP GET request to a page and get the result back</button>


</body>
</html>

Express.js发送数据查看未发送，出了什么问题
