Javascript 如何将数据数组从express.js传递到ejs模板并呈现它们
我在我的nodejs web应用程序中使用Javascript 如何将数据数组从express.js传递到ejs模板并呈现它们,javascript,node.js,express,ejs,Javascript,Node.js,Express,Ejs,我在我的nodejs web应用程序中使用express.js，用户输入一些条件，程序得到如下数据数组： var data = [ { name: 'Salmons Creek', image: 'https://farm6.staticflickr.com/5479/11694969344_42dff96680.jpg', description: "Great place to go fishin' Bacon ipsum dolor amet kielbasa

我想使用EJS模板语言来渲染数组中的所有对象。如何将数据传递到模板并呈现它们？在js文件中，您应该像这样呈现EJB：
var express = require('express');
var app = express();
var path = require('path');
// viewed at http://localhost:8080
app.use("/", express.static(__dirname + '/'));
app.set('view engine', 'ejs');
app.get('/', function(req, res) {
var data = [
{
name: 'Salmons Creek',
image: 'https://farm6.staticflickr.com/5479/11694969344_42dff96680.jpg',
description: "Great place to go fishin' Bacon ipsum dolor amet kielbasa cow"
},
{
name: 'Granite Hills',
image: 'https://farm5.staticflickr.com/4103/5088123249_5f24c3202c.jpg',
description: "It's just a hill. Made of granite. Nothing more! Cow doner."
},
{
name: 'Wildwood Miew',
image: 'https://farm5.staticflickr.com/4016/4369518024_0f64300987.jpg',
description: 'All campsites. All the time.Short ribs pastrami drumstick.'
},
{
name: 'Lake Fooey',
image: 'https://farm7.staticflickr.com/6138/6042439726_9efecf8348.jpg',
description: 'Hills and lakes and lakes and hills. Pork ribeye pork chop.'
}
];
res.render('index.ejs', {data:data} );
});
app.listen(8080);
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<ul>
<% data.forEach(function(dat) { %>
<li><%= dat.name %></li>
<li><%= dat.image%></li>
<li><%= dat.description%></li>
<% }); %>
</ul>
</body>

如何准确地渲染它们？就像字符串一样，在元素中？您必须给我们一个您想要的输出示例。大多数模板引擎的可能副本都有所谓的上下文。在ejs中，它是渲染方法的第二个参数。因此，您可以执行类似于
res.render（'page1'，{data:data}）
