Wikimedia Commons has a set of electrical symbols in SVG format and you can search for svg electronics too. This is a good start to be used with JS drawing libraries.
I would recommend you find a library that has drawing capabilities, then write a plug-in for that library that would draw circuit elements where needed. Raphael is a pretty nice and easy-to-use drawing library.

维基共享资源有一组SVG 格式的电气符号您也可以搜索
svg electronics。这是与 JS 绘图库一起使用的良好开端。Wikimedia Commons has a set of electrical symbols in SVG format and you can search for
svg electronicstoo. This is a good start to be used with JS drawing libraries.我不知道哪个库可以满足您的要求，但有三个库可以作为良好的开始。
它们都有正确的原语，您可以从中构建。
I don't know of a library that does what you want, but there are three libraries that could be good starts.
They all have the right primitives to start with that you could build off of.
我建议您找到一个具有绘图功能的库，然后为该库编写一个插件，以便在需要时绘制电路元件。 Raphael 是一个非常漂亮且易于使用的绘图库。

有一个名为 WireIt 的库，它可以帮助您绘制电路图，我希望它可以帮助您，甚至您可以使用 webtronics。
there is a library called WireIt , it can help you drawing circuit diagrams i hope it helps you or even you can go for webtronics.
尝试DC/AC Virtual Lab，不久的将来会添加更多组件..
Try DC/ AC Virtual Lab , more components are added in the near future ..
