如何将样式表添加到JSDOM [英] How do you add stylesheets to JSDOM
问题描述
我目前正在从事一个项目，该项目要求我将计算出的样式通过JSDOM发送到浏览器.我目前正在寻找一种将一些基本CSS注入JSDOM的方法，以便可以计算出正确的内联样式(是的，我知道那很不好).
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).
从我发现的内容来看，我可以使用JSDOM 2级，但是从那里我找不到任何有关如何注入样式的文档.
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.
这是我到目前为止所拥有的；
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
}
});
我一直在将css插入head标签，但无济于事.而且我知道我也可能在上面的代码中做错了.
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.
任何帮助都会很棒.
推荐答案
嗯，这听起来有点愚蠢，但这是我所做的:
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);
所以基本上我所做的只是将级别移动到3索引，而不是直接在起始html中添加它，而是在其后附加了它.
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.
它非常简单，我希望它可以帮助其他人.
Its pretty simple and I hope it helps someone else out.
