我想运行Express 3.3.x及其默认实现。 Express使用其路由模块,所以我必须做什么,如果任何路由中的任何视图都可以访问JS和CSS?
/**
* Module dependencies.
*/
var express = require('express');
var http = require('http');
var path = require('path');
var piler = require('piler');
var mongoose = require('mongoose');
var config = require('./config');
var app = exports.app = express();
var js = piler.createJSManager();
var css = piler.createCSSManager();
var srv = require('http').createServer(app);
// all environments
js.bind(app,srv);
css.bind(app,srv);
app.set('port', process.env.PORT || 3000);
app.set('views', __dirname + '/views');
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(express.cookieParser('your secret here'));
app.use(express.session());
app.use(app.router);
app.use(require('less-middleware')({ src: __dirname + '/public' }));
app.use(express.static(path.join(__dirname, 'public')));
js.addUrl("http://ajax.googleapis.com/ajax/libs/jquery/1.6.2/jquery.js");
// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}
/**
* Routes
*/
var routes = require('./routes');
app.get('/', routes.index);
srv.listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});
在piler的例子中:
app.get("/", function(req, res){
res.render("index.jade", {
layout: false,
js: js.renderTags(),
css: css.renderTags()
});
});
这很有效。但我有
app.get('/', routes.index);
那么我必须做的是,js.renderTags()在每个视图中都有效吗?
答案 0 :(得分:2)
如果您尝试将变量传递给渲染,则可以使用res.locals
app.use(function(req,res,next){
res.locals.layout= false;
res.locals.js= js.renderTags();
res.locals.css= css.renderTags();
next();
});
在路由器之前使用此功能,但不要覆盖您的本地人(res.locals={...}
)
