javascript - JavaFX Web View :sending a String from javafx to js webview

Question

我目前使用 WebEngine 渲染网页。我想将一个 String 从 Java 方法发送到 WebView 以在 map 弹出窗口(传单)中显示它。

有人知道我做错了什么吗？

 webEngine.executeScript("addpopup(" + new_val.getDescription() + "," + new_val.getLatitude() + "," + new_val.getLongitude() + ")");

相关 JavaScript 代码:

function addpopup(desc,lan,lat){
    var popup = L.popup().setLatLng([lan, lat]).setContent(desc).openOn(map);
}

无需描述参数即可工作。

我认为您缺少 new_val.getDescription() 周围的引号:

webEngine.executeScript("addpopup('" + new_val.getDescription() + "'," 
     + new_val.getLatitude() + "," + new_val.getLongitude() + ")");
