问题 After reading this Micro templates are dead article. I've become curious: Whether Using the DOM on the server results in cleaner more maintainable code then templating. Whether it's more efficient to use jsdom instead of a templating engine. How to factor jsdom into the View of a standard MVC setup.

But when it comes to D3.js, for example: var svg = d3.select("body").append("svg") as you can see d3 requires DOM to be available on first place. So, for that reason JSDOM is supposed to be the solution.

问题 M. Bostock pointed out that nodejs' jsdom have incomplete support for svg, and, critical for me, doesn't support getBBox() . Also, he advised to switch to nodejs' PhantomJS. I checked out but the approach is new to me. My nodejs + jsdom script create a virtual DOM, with which my d3js plays and is as follow : var jsdom = require('jsdom'); jsdom.env( // creates virtual page "<html><body></body></html>", // create my DOM hook, [ 'http://d3js.org/d3.v3.min.js', // add my online dependencies ...

问题 I am currently working on a project that requires me to have computed styles send to the browser via JSDOM. I am currently looking for a way to inject some basic CSS into JSDOM so that it could compute the correct inline style (Yes I know that's bad).

This is what I have so far; var document = jsdom.jsdom('<!DOCTYPE html><html><head></head><body id="abody" ></body><

问题 Cross-posted from https://github.com/tmpvar/jsdom/issues#issue/127 I will post a minimal test case in the next day or so - but I wanted to see if anyone else had the same problem - or if (more likely) if I am doing something stupid. I'm using NodeJS v2.6 on Ubuntu 10.04 AMD64 and jsdom@0.1.23. var file = readFileSync("./www/index.html", "utf8"); var window = jsdom.jsdom(file).createWindow(); All inline scripts run, but complain about missing variables which should be supplied by the external

阅读更多关于 node.js: problems with jsdom - jQuery object returns undefined

问题 I am interested in doing some server-side DOM manipulations for one of projects, so I decided to take a look at node.js, and at jsdom in particular.

问题 I have a script to scrape ~1000 webpages. I'm using Promise.all to fire them together, and it returns when all pages are done: Promise.all(urls.map(url => scrap(url))) .then(results => console.log('all done!', results)); This is sweet and correct, except for one thing - machine goes out of memory because of the concurrent requests. I'm use jsdom for scrapping, it quickly takes up a few GB of mem, which is understandable considering it instantiates hundreds of window . I have an idea to fix

问题 I've installed jsdom on my windows 8.1 machine. If I am one directory above my local installation of jsdom, I can call node jsdom and everything works. However, if, from the same dir / pwd, I call a script (at a different path) with require("jsdom").jsdom; I get errors of the type Error: cannot find module 'jsdom' 回答1: If you omit the extension, node will resort to looking in the node_modules folder for a package named "jsdom" (installed via NPM).
