Zombiejs jQuery nullTypeError 'compareDocumentPosition'

由 流过昼夜 提交于 2020-02-25 09:22:29
问题 Zombie: Cannot read property 'compareDocumentPosition' of null TypeError: Cannot read property 'compareDocumentPosition' of null This happens any time I try to load a page that includes jQuery using Zombiejs. This has happened to me on Debian & Windows, with a variety of different pages, using different versions of jQuery and with nothing else on the page. It seems to have something to do with the way jsDom evaluates jQuery before the page document is ready, but it's pretty far over my head.

disable CORS checking in jsdom on nodejs

由 纵然是瞬间 提交于 2020-01-04 21:30:57
问题 Is it possible to disable the CORS checking functionality in the jsdom node module? The CORS errors are particularly difficult to debug in my use case (clientside testing) and do not occur in the actual environment I am running the program. Perhaps some environmental variable we can set when initializing the object? e.g., window = new jsdom.JSDOM(``,{ cors : false, }).window; 回答1: As stated in this issue on JSDOM Github repository, JSDOM acts like a browser and the same-origin policy applies.

Azure and Node.js and JSDOM scheduled task - opening a webpage with scripts

问题 I have an Azure website that has uses a thirty party script (DHTMLX Schedule library). I want to be able to render out a PDF and send it as an email as a weekly automated task. I have a C# MVC page that is using their .NET Scheduler to render the schedule and at the moment, when the page loads in a browser it essentially does everything I need. However I am trying to create this as a scheduled task in Azure. The page has a lot of JavaScript and CSS which renders out the schedule which gets

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

由 雨燕双飞 提交于 2020-01-02 04:29:11
问题 I am still foggy about how to used jsdom. What is the difference between jsdom.env() and jsdom.jsdom? 回答1: 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

How do I return a value from a simple jsdom function?

由 一世执手 提交于 2020-01-01 05:39:25
问题 I'm using jsdom with jquery, and it's working just fine. However, I'm trying to modularize my code a bit so I don't repeat myself, so I made a basic function out of some jsdom code that takes in some html (DOM), tweaks it with jquery, and spits it back out. However, I'm unable to return my result and thus assign it to a calling var. I'm probably not returning in the right place, but I'm just not seeing the obvious if so. Could use a little help. Here's the code: function tweakIt(html_in){ var

Testing Typescript Generated Classes with node.js, Mocha and mocha-jsdom?

由 十年热恋 提交于 2019-12-25 08:36:40
问题 I would like to run unit tests from bash to test my Typescript generated Javascript classes using mocha and mocha-jsdom. I'm using mocha-jsdom because I want to emulate the dom in my tests but run unit tests from bash. I've seen a few examples where they use the frontend testing framework for mocha in a browser, but I haven't seen any where they are run from bash. It appears that I am unable to include the Javascript classes generated from Typescript in my mocha unit tests. var jsdom =
