I have very simple html code (no css, nor js) that includes five inputs with
type="radio" (in one column) and webview in JavaFX 8 which loads this page.
The problem is the following - sometimes these radios are rendered sometimes
not.
For example, I start application - webview loads page, however there is empty
space where these radio must be (these inputs are not rendered,they are not
seen). But, when I move mouse over the area where these radios must be, they
appear.
I see this problem in Linux - Centos, Ubuntu and Windows XP. I've not seen this
problem in Win7.
Here is the code I tested. All the program consists of two classes:
public class JavaFXApplication extends Application {
private int count=0;
@Override
public void start(Stage primaryStage) {
final Button printButton = new Button("Print");
final WebView webPage = new WebView();
final WebEngine webEngine = webPage.getEngine();
printButton.setOnAction(new EventHandler<ActionEvent>() {
@Override public void handle(ActionEvent e) {
String html="<html dir=\"ltr\"><head>\n" +
" <meta http-equiv=\"content-type\" content=\"text/html; charset=utf-8\">\n"
+
"</head>\n" +
"<body contenteditable=\"true\">\n" +
" \n" +
" \n" +
" \n" +
"\n" +
"\n" +
"<p align=\"justify\" style=\"text-align: left; margin-bottom: 0in;
line-height: 150%;margin-bottom: 0in; line-height: 100%\">\n" +
"<font style=\"font-size: 14pt\" face=\"serif\">Стали бы Вы на пути\n" +
"грабителя грузового вагона?</font></p><p align=\"justify\" style=\"text-align:
left; margin-bottom: 0in; line-height: 150%;\"><font style=\"font-size: 14pt\"
face=\"serif\">Выберите ответ:</font></p>\n" +
"\n" +
"<form name='mainForm' style='margin-top:15px;'>\n" +
"<input type='radio' name='answer' value='641' ><font size='4'>Полностью
согласен, полное «Да»</font><br>\n" +
"<input type='radio' name='answer' value='642' ><font size='4'>Больше «Да», чем
«Нет»</font><br>\n" +
"<input type='radio' name='answer' value='643' ><font size='4'>Ни «Да», ни
«Нет», нечто среднее</font><br>\n" +
"<input type='radio' name='answer' value='644' ><font size='4'>Больше «Нет»,
чем «Да»</font><br>\n" +
"<input type='radio' name='answer' value='645' ><font size='4'>Полное
«Нет»</font><br>\n" +
"</form><script type=\"text/javascript\">\n" +
"function getAnswerId(){\n" +
" var elements = document.getElementsByName(\"answer\");\n" +
" for (var i=0, len=elements.length; i<len; ++i) {\n" +
" if (elements[i].checked) return elements[i].value;\n" +
" }\n" +
" return null;\n" +
"}\n" +
"</script></body></html>";
html+=count;
count++;
webEngine.loadContent(html);
}
});
HBox hbox = new HBox();
hbox.getChildren().addAll(printButton);
BorderPane borderPane = new BorderPane();
borderPane.setTop(hbox);
borderPane.setCenter(webPage);
Scene scene = new Scene(borderPane, 300, 250);
primaryStage.setTitle("WebView radio bugs");
primaryStage.setScene(scene);
primaryStage.show();
}
}
And the second class
public class JavaApplication {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
Application.launch(JavaFXApplication.class, args);
}
}
After that I click Print button. After every clicking count++. Compiled openjdk
1.8.45. Tested winxp oracle 1.8.40, centos71,ubuntu 12 oracle 1.8.60. The image
from xp. 29 clicks after that no radios. Moved mouse over 1,3,5: . The result
is on the image I attached. Please, answer.
