阅读更多关于 How can I turn an EJS template into a string?

问题 I want to pass my variables into that template, let it render, and then get the resulting HTML as a string. How can I do that in Express? 回答1: Depending on the ejs version the following should work. var ejs = require('ejs'), fs = require('fs'), file = fs.readFileSync(__dirname + '/template.ejs', 'ascii'), rendered = ejs.render(file, { locals: { items:[1,2,3] } }); console.log(rendered); You may need to install ejs if it isn't already installed. cd;npm install ejs 回答2: You don't need to use fs

Nodejs express中创建ejs项目,解决express下默认创建jade,无法创建ejs问

阅读更多关于 Nodejs express中创建ejs项目,解决express下默认创建jade,无法创建ejs问

最近在看《Node.js开发指南》，看到使用nodejs进行web开发的时候，准备创建ejs项目遇到问题了，书上命令为： 1 express -t ejs microblog 可是执行后，仍旧创建的是jade项目。原来，express3.x，express4.x中创建ejs命令更新为： express -e microblog //即ejs，-j（即jade）当然，最直接的，你也可以修改package.json里的定义来实现安装ejs。 PS：建立工程过程 1.必须得安装express框架把：express的安装命令也更新了，需要安装express-generator $ npm install -g express //全局安装 $ npm install -g express-generator //这段命令可别忘了，不然会提示“express命令找不到的” 2.建立网站工程结构： express -e ejs microblog 3.根据提示，进入文件夹安装 cd microblog //microblog为前面创建工程的文件夹 npm install 来源： oschina 链接： https://my.oschina.net/u/1538660/blog/704248

问题 I use EJS template engine in my Node.js and Express app, and have used its functionality and rendering so far, and haven't had any problems so far. However, while I always used the syntax res.render(filename, options, callback) in my server-side program to render the contents of the file, I wonder what's the difference between res.render() and ejs.render() . It looks like both methods take a rendering filename as a first argument and Object to embed to the file as a second argument (like

问题 I have a global header used in a couple of places and I was trying to define its location in a variable that could be passed when rendering a template. Something like: var headerLocation = 'some/location/header.ejs'; res.render( viewDir + '/index', { header: headerLocation } ); And in a template file: <% include header %> header being the value passed in with the render.

Embedding an ejs template inside of an erb template

阅读更多关于 Embedding an ejs template inside of an erb template

问题 I'm building a javascript-heavy rails 3 app. It uses underscore.js, which has a very elegant templating mechanism built on top of ejs ( http://embeddedjs.com/). The problem: embeddedjs borrows heavily from the erb syntax, so including ejs templates in an erb template causes rendering problems with the view. Is there a way to include "non-erb" sections in an erb file? This would let me define ejs templates inside erb files. Right now I'm using a hack where I have a helper that reads the raw

阅读更多关于 Passing a function into an EJS template for use in an onclick event?

I'm trying to pass a function into an EJS template and have it be set to an onclick event in the template. Is this possible? In other words, something like this var clickHandler = function() { console.log("I am in the click handler!"); } var template = new EJS({ url: "/template.ejs" }); var html = template.render({ clickHandler: clickHandler }) $("#target").html(html); Where the template looks something like <p onclick='clickHandler'>Click Me</p> Radian Jheng You should put your js function in the .ejs file instead of the server file. You should pass the function name instead of the entire
