问题描述:
我在网上的NodeJS应用程序,用户输入一些条件使用express.js
和程序获取数据的数组像这样:如何从express.js数据数组传递给EJS模板,并将其呈现
var data = [
{

我想使用EJS模板语言来渲染数组中的所有对象。我如何将数据传递给模板并渲染它们?
答
在您的JS文件,你应该呈现这样的EJS:
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);
而在你EJS文件,您可以呈现这样的数据变量:
<!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>
</html>
我已经尝试过了,它作品。
的文件夹结构是这样的:
.
+-- app.js
+-- views
| +-- index.js
使它们究竟如何?就像一个字符串,在元素中?你必须给我们一个你想要的输出的例子 – adeneo
[用EJS模板传递变量]的可能重复(https://stackoverflow.com/questions/25596615/passing-variable-with-ejs-templating) –
大多数模板引擎具有所谓的上下文。在ejs中,它是渲染方法的第二个参数。所以你应该做一些像'res.render('page1',{data:data})'这些数据应该可以用于你的EJS脚本。 – Keith
