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 {
    @Override
    public 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 {
    @Override
    public 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 {
    @Override
    public 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 {
    @Override
    public 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);
    }
}
