HTMLEditor类返回HTML字符串中的编辑内容。

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); } }

上面的代码生成以下结果。

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); } }

上面的代码生成以下结果。

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); } }

上面的代码生成以下结果。

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); } }
