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).
From what I have found out I can use JSDOM Level 2, but from there I can't find any documentation on how to inject the styles.
This is what I have so far;
var document = jsdom.jsdom('<!DOCTYPE html><html><head></head><body id="abody" ></body></html>', jsdom.level(2, 'style'), {
features : {
FetchExternalResources : ['script', 'css'],
QuerySelector : true
}
});
I have been inserting the css into the head tag but to no avail. And I know I could be doing the above code wrong as well.
Any help would be great.
Well, this is going to sounds kinda dumb but this is what I did:
var path = require('path');
var fs = require('fs');
var mainCss = fs.readFileSync(path.normalize(__dirname + "web_main.css"), 'utf8');
var document = jsdom.jsdom('<!DOCTYPE html><html><meta http-equiv="content-type" content="text/html; charset=utf-8"><head></head><body id="abody" ></body></html>', jsdom.level(3, 'index'), {
features : {
FetchExternalResources : ['script', 'css'],
QuerySelector : true
}
});
var window = document.createWindow();
var head = document.getElementsByTagName('head')[0];
style = document.createElement("style");
style.type = 'text/css';
style.innerHTML = mainCss;
head.appendChild(style);
So basically all I changed was moving the level to 3 index, and instead of directly having it in the starting html, I appended it afterwards.
Its pretty simple and I hope it helps someone else out.
