onRendered callback height is before when before height is larger than new actual height.

When embed in tableViewCell, need update everytimes after load markdown, but onRendered callback height is before when before height is larger than new actual height, so I add the below method to get the actual height

public func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
        // 获取内容实际高度
        webView.evaluateJavaScript("document.body.scrollHeight") { [unowned self] (result, error) in
            DispatchQueue.main.async { [unowned self] in
                if let tempHeight: Double = result as? Double {
                    let height = CGFloat(tempHeight) + 10
                    debugPrint("height ==== \(height)")
                    self.onRendered?(height)
                }
            }
        }
    }

@cellgit Bro, there is a wiser fix change the postDocumentHeight func to

const postDocumentHeight = () => {
    var _body = document.body;
    var _html = document.documentElement;
//    var height = Math.max(
//                          _body.scrollHeight,
//                          _body.offsetHeight,
//                          _html.clientHeight,
//                          _html.scrollHeight,
//                          _html.offsetHeight
//                          );
    var height = _html.offsetHeight;
    console.log(height)
    window?.webkit?.messageHandlers?.updateHeight?.postMessage(height);
};

@kasimok Why is my main.js compressed? Where can I see the source code?

it is for performance concern, you can use tools like vscode to decompress it.
