javaFX

Question

में वेब व्यू से चयन किए गए टेक्स्ट को कैसे प्राप्त करें मुझे javaFX में वेब व्यू से चयनित टेक्स्ट प्राप्त करने की आवश्यकता है। मुझे कोई संकेत नहीं मिला कि इंटरनेट पर इसे कैसे किया जाए।

Answer 1

यह जावा स्क्रिप्ट के साथ किया जा सकता है:

String selection = (String) webView.getEngine() 
        .executeScript("window.getSelection().toString()"); 
System.out.println(selection); 

इसके अलावा आप पा सकते हैं यह सहायक:
Communicating between JavaScript and JavaFX with WebEngine
executeScript

Answer 2

कोई भी चयनित टेक्स्ट और एचटीएमएल दोनों निकाल सकता है जैवफैक्स वेबव्यू से हमारा कोड:
