我正在尝试从data.json文件中解析数据,我想将网站的所有数据存储在此json文件中,然后将数据解析至index.ejs文件。下面是我的index.ejs文件,app.js(用于设置的文件)和data.json文件的代码段。
HTML代码段(index.ejs)
<ul class="menu-list">
<li><%= data.menu.title %></li>
</ul>
Json文件(data.json)
{
"data": {
"menu": [
{
"title": "Home",
"link": ""
},
{
"title": "Contact",
"link": ""
}
]
}
}
设置文件(app.js)
var createError = require('http-errors');
var express = require('express');
var path = require('path');
var cookieParser = require('cookie-parser');
var logger = require('morgan');
var sassMiddleware = require('node-sass-middleware');
var indexRouter = require('./routes/index');
var usersRouter = require('./routes/users');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(logger('dev'));
app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cookieParser());
// compiling sass files
app.use(sassMiddleware({
src: path.join(__dirname, 'public/stylesheets/scss'),
dest: path.join(__dirname, 'public/stylesheets'),
debug: true,
outputStyle: 'compressed',
prefix: '/stylesheets'
}));
app.use('/public', express.static(path.join(__dirname, 'public')));
app.use('/', indexRouter);
app.use('/users', usersRouter);
// catch 404 and forward to error handler
app.use(function(req, res, next) {
next(createError(404));
});
// error handler
app.use(function(err, req, res, next) {
// set locals, only providing error in development
res.locals.message = err.message;
res.locals.error = req.app.get('env') === 'development' ? err : {};
// render the error page
res.status(err.status || 500);
res.render('error');
});
module.exports = app;
原谅我的缩进-怪异的。所有文件都处于同一级别。
答案 0 :(得分:0)
在您的示例中,将<li><%= data.menu.title %></li>
替换为<li><%= data.menu[0].title %></li>
,因为菜单不是数组数据
样本数据
var data =
{"data": {
"menu": [
{
"title": "Home",
"link": ""
},
{
"title": "Contact",
"link": ""
}
]
} };
Ejs代码
<ul class="menu-list">
<% for(var i=0; i < data.data.menu.length; i++) { %>
<li><%= data.data.menu[i].title %></li>
<% } %>
</ul>
