Loading ajax app with jsdom

阅读更多关于 Loading ajax app with jsdom

问题 I'm looking for a solution to bootstrap a client side app (written in Backbone.js) on the server, so that I can serve correct content to crawlers and non-js consumers. I've been playing around with jsdom & nodejs in an attempt to bootstrap the app, and can get it as far as loading in the basic template content, but the app appears to never start. I've tried 2 different solutions to make sure that I have all the dependencies necessary and the app is loading correctly: I tried using jsdom.env()

D3js : How to convert svg text to path?

阅读更多关于 D3js : How to convert svg text to path?

问题 Is there a D3.js way to convert a text element into a path element? So when I grasp the generated svg, I could keep my the texts shapes. 回答1: There is no way in JavaScript (d3 or any other tool) to access the vector path information about the shape of individual letters in system or web fonts. It's a requested feature for SVG 2, but there are no firm proposals for how it would work. The Raphael method described in the question linked by Lars Kotthoff uses a font object that has already been

I looks like when I run a page through jsdom , the $(document).ready block in the page script isn't being executed. Here is the html: <html> <body> If everything works, you should see a message here: <h2 id="msg"></h2> <script> var checkpoint1 = true var checkpoint2 = false $(document).ready(function(){ checkpoint2 = true $('#msg').html("It works, it works, it works!") }) </script> </body> </html> and the codez: fs = require('fs'); htmlSource = fs.readFileSync("public/examples/test_js_dom.html", "utf8"); global.jsdom = require("jsdom"); jsdom.defaultDocumentFeatures = { FetchExternalResources

What is the difference between jsdom.env() and jsdom.jsdom?

阅读更多关于 What is the difference between jsdom.env() and jsdom.jsdom?

I am still foggy about how to used jsdom. What is the difference between jsdom.env() and jsdom.jsdom? The readme file explains that jsdom.env is built for ease of use, which is rare in the world of the DOM! Since the web has some absolutely horrible javascript on it, as of jsdom 0.2.0 jsdom.env will not process external resources (scripts, images, etc). If you want to process the javascript use one of the methods below (jsdom.jsdom or jsdom.jQueryify) 来源： https://stackoverflow.com/questions/5605961/what-is-the-difference-between-jsdom-env-and-jsdom-jsdom

Testing React portals with enzyme

问题 So I'm having a hard time writing tests for a modal component using React fiber's portal. Because my modal mounts to a domNode on the root of the <body /> but because that domNode doesn't exist, the test fails.

I'm new to unit testing, and I'm aware my tests may not be valuable or following a specific best practice, but I'm focused on getting this working, which will allow me to test my frontend code using JSDOM. const { JSDOM } = require('jsdom'); const { describe, it, beforeEach } = require('mocha'); const { expect } = require('chai'); let checkboxes; const options = { contentType: 'text/html', }; describe('component.js', () => { beforeEach(() => { JSDOM.fromFile('/Users/johnsoct/Dropbox/Development/andybeverlyschool/dist/individual.html', options).then((dom) => { checkboxes = dom.window.document

问题 I want to programatically find a list of URLs for similar images given an image URL. I can't find any free image search APIs so I'm trying to do this by scraping Google's Search by Image.

How do I get jsdom.env to produce the HTML your browser gets from the above URL? Here's what I've tried ( CoffeeScript ):

How to test JavaScript with DOM elements using jasmine?

阅读更多关于 How to test JavaScript with DOM elements using jasmine?

I am trying to write a test in jasmine for JavaScript code including DOM elements which doesn't work. It works when I test only for JavaScript code (just simple functions but not for DOM elements). I have been researching for so long and can't really find the answer. I also tried to use jsdom as it's supposed to be used when testing for DOM elements, however I keep getting a bunch of errors. Is there any 'easy' way to test DOM elements only using jasmine? JavaScript: var result; var adding = function(one, two) { var one1 = document.forms["myForm"]["one"].value; var two1 = document.forms[
