由 丶灬走出姿态 提交于 2019-12-01 17:29:27
I want to use a variable which is declared in javascript file to a ejs file. javascript: var express = require('express'); var app = express(); var myVar = 1; In the ejs file , where I want to use that variable inside a few if statements ,I have to declare it again in order to be able to use it. ejs file: var myVar = 1; if ( my Var ) ....

I tried also to use: app.locals.myVar = 1 but it is undefined in the ejs file. ------- UPDATE -------------------------- In my code I am

问题 I'm just trying to get setup with node.js/express/ejs. I know ejs isn't actual HTML and so I'm having a hard time just displaying a simple image. Can someone point me in the right direction? Directory structure is: myApp/server.js myApp/views/index.ejs myApp/logo.jpg Right now I have // index.ejs <img src = "../logo.jpg" /> Am I going about this the wrong way? Thanks. 回答1: Static files in Express must go inside the directory specified in your static middleware. This is commonly ./public/ .

Node.js express: confuse about ejs template

由 核能气质少年 提交于 2019-12-01 09:18:05
I put my ejs template file in views folder like: views | |--foo.html | |--layout.html so I config my ejs template: app.set('views', __dirname + '/views'); app.engine('html', require('ejs').renderFile); I render my foo template by this: res.render('foo.html', {title: 'test'}); I want use layout.html as the master layout template, I also add <%- body%> tag in layout.html , but is doesn't work, what I saw is only return the ended foo.html . Why the layout.html can't be the master layout?Or how can I set it to the master layout? Ahah you just got tricked by Express 3 change in layout management.

Dynamic templates in EJS (node.js)

由 ♀尐吖头ヾ 提交于 2019-12-01 07:18:24
问题 Does anybody know a nice solution for including templates, whose names would be known only at run time? EJS's includes allows only to specify exact file/template name. Use case : I have a article layout and there is article HTML/EJS content in some local file. To do so I need something like https://github.com/visionmedia/ejs#includes but file name should be taken from locals variable: Assume I have such handler (simplified): app.get('/article/:article', function (req, res) { var

问题 Well, SailJS's default templateing engine is EJS ( Embedded Javascript ) But I cannot seem to find the place where we can create our own helpers and stuff.

I'm using nodejs and mongodb in the back end for an app I'm working on. I'm using express to test the app, and I'm trying to use ejs to render my html files.
