基本上，我需要以字符串的形式获取数据（与问题无关），并通过jQuery将其附加到Javafx WebView中。此链接是我找到如何嵌入jQuery并将jQuery函数调用到WebView的地方：https：//community.oracle.com/message/10446280?tstart=1。'
。解释代码：我正在一个Eclipse RCP项目中工作，其中主ViewPart是一个容纳WebView的Javafx场景的容器。WebEngine加载页面。下面的代码抓住视图，获取场景，然后获取WebView。EditorPart获取当前活动编辑器的内容（最终将注入WebView）。现在，我只有一些用于测试的临时代码。可以在链接中更好地解释ExecuteJquery。
代码：
HandlerUtil.getActiveWorkbenchWindow(event).getActivePage().showView("com.interpro.emmeclipse.views.PageBuilderPart");
FXSceneProvider view = (FXSceneProvider) page.findView("com.interpro.emmeclipse.views.PageBuilderPart");
Scene scene = (Scene) view.getScene();
AnchorPane node = (AnchorPane)scene.getRoot();
WebView webview = (WebView) node.getChildren().get(0);
final WebEngine engine = webview.getEngine();
final IEditorPart activeEditor = PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor();
if (activeEditor != null) {
final IDocument doc = (IDocument) activeEditor.getAdapter(IDocument.class);
if(doc != null){
System.out.println(doc.get());
engine.documentProperty().addListener(new ChangeListener<Document>() {
@Override public void changed(ObservableValue<? extends Document> prop, Document oldDoc, Document newDoc) {
executejQuery(
engine,
"$("#content").append(<div class='ui-statusbar'><h5 class='ui-title'>Test</h5></div>);"
);
}
});
}
}

线程" Javafx应用程序线程"中的例外
我认为下一行由于缺乏报价而产生错误：
"$("#content").append(<div class='ui-statusbar'><h5 class='ui-title'>Test</h5></div>);"
尝试
"$("#content").append("<div class='ui-statusbar'><h5 class='ui-title'>Test</h5></div>");"
