IOS WKWebView - 隐藏网站页眉和页脚

Question

如何使用 Wkwebview 加载网址来隐藏页眉和页脚？最有可能传递网页读取的一些参数或 cookie 并对其采取操作。

class TermCond_PrivacyPoli_VC: UIViewController , WKNavigationDelegate, WKUIDelegate {



var HC = "https://www.hospi24.com/hospi24/company/privacy";


override func viewDidLoad() {
    super.viewDidLoad()
    let  webViewK = WKWebView(frame: CGRect(x: 0, y: 70, width: self.view.frame.size.width, height: self.view.frame.size.height))
    self.view.addSubview(webViewK)
    webViewK.uiDelegate = self;
    webViewK.navigationDelegate = self
    let url = URL.init(string: "https://www.hospi24.com/hospi24/company/privacy") //URL (string: TNC)
    let request = URLRequest(url: url!)
    webViewK.load(request)

}



func webView(webView: WKWebView, didFinishNavigation navigation: WKNavigation!) {
    print("finish to load")
}


func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {

    print("finish to load")
    let elementID = "bottomMenu"
    let removeElementIdScript = "var element = document.getElementsByClassName(('\(elementID)[0].style.display=\"none\";'); element.parentElement.removeChild(element);"
    webView.evaluateJavaScript(removeElementIdScript) { (response, error) in
        debugPrint("Am here")
    }
}

您可以通过在请求中传递 cookie 参数来隐藏页眉和页脚。所以在服务器端基于cookie的页眉和页脚将是可见的，或者您可以应用Javascript代码使其通过JavaScript禁用，您可以在didFinish Delegate

中使用此代码

public func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
 self.wkwebView.evaluateJavaScript("document.getElementById(\"header\").style.display='none';") { (result, error) in
        if error == nil {
            // header is hide now
        }
}
