首先在WKWebView上创建一个扩展，该扩展定义了一个'runJavaScriptInMainFrame：'方法。在扩展方法中，使用NSInvocationOperation

NSInvocationOperation类是NSOperation的具体子类您用来启动包含以下内容的操作的操作：指定对象上的选择器。此类实现非并发操作。

调用未记录的'_runJavaScriptInMainFrame：'方法。

 extension WKWebView {
        func runJavaScriptInMainFrame(#scriptString: NSString) -> Void {
            let selector : Selector = "_runJavaScriptInMainFrame:"
            let invocation = NSInvocationOperation(target: self, selector: selector, object: scriptString)
            NSOperationQueue.mainQueue().addOperation(invocation)
        }
    }

现在叫这个：-

webview.runJavacriptInMainFrame:(scriptString: "Write Particular javascript code")

如何在wkwebview中打开'window.open'
