创建HTML编辑器

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;public class Main extends Application {@Overridepublic void start(Stage stage) {HTMLEditor htmlEditor = new HTMLEditor();htmlEditor.setPrefHeight(245);Scene scene = new Scene(htmlEditor);       stage.setScene(scene);stage.show();} public static void main(String[] args) {launch(args);}
}

HTML内容

要将内容设置为HTMLEditor类，请使用setHtmlText方法。

htmlEditor.setHtmlText(INITIAL_TEXT);

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;public class Main extends Application {@Overridepublic void start(Stage stage) {HTMLEditor htmlEditor = new HTMLEditor();htmlEditor.setPrefHeight(245);String INITIAL_TEXT = "Lorem ipsum dolor sit "+ "amet, consectetur adipiscing elit. Nam tortor felis, pulvinar "+ "aliquam sagittis gravida eu dolor. Etiam sit amet ipsum "+ "sem.";htmlEditor.setHtmlText(INITIAL_TEXT);Scene scene = new Scene(htmlEditor);       stage.setScene(scene);stage.show();} public static void main(String[] args) {launch(args);}
}

格式

我们可以使用此字符串中的HTML标记为最初渲染的内容应用特定的格式。

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;public class Main extends Application {@Overridepublic void start(Stage stage) {HTMLEditor htmlEditor = new HTMLEditor();htmlEditor.setPrefHeight(245);String INITIAL_TEXT = "Lorem ipsum dolor sit "+ "amet, consectetur adipiscing elit. <i>Nam tortor felis</i>, pulvinar "+ "<UL><li>a</li><li>a</li><li>a</li></UL>"+ "aliquam sagittis gravida <b>eu dolor</b>. Etiam sit amet ipsum "+ "sem.";htmlEditor.setHtmlText(INITIAL_TEXT);Scene scene = new Scene(htmlEditor);       stage.setScene(scene);stage.show();} public static void main(String[] args) {launch(args);}
}

获取HTML内容

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;public class Main extends Application {@Overridepublic void start(Stage stage) {HTMLEditor htmlEditor = new HTMLEditor();htmlEditor.setPrefHeight(245);String INITIAL_TEXT = "Lorem ipsum dolor sit "+ "amet, consectetur adipiscing elit. <i>Nam tortor felis</i>, pulvinar "+ "<UL><li>a</li><li>a</li><li>a</li></UL>"+ "aliquam sagittis gravida <b>eu dolor</b>. Etiam sit amet ipsum "+ "sem.";htmlEditor.setHtmlText(INITIAL_TEXT);Button showHTMLButton = new Button("Produce HTML Code");showHTMLButton.setOnAction((ActionEvent arg0) -> {System.out.println(htmlEditor.getHtmlText());});VBox vbox = new VBox();vbox.getChildren().addAll(htmlEditor,showHTMLButton);Scene scene = new Scene(vbox);       stage.setScene(scene);stage.show();} public static void main(String[] args) {launch(args);}
}
