当我点击我的JavaFX应用程序的Button时,我一直在尝试在地图上显示标记.所以当我点击该按钮时,我在JSON文件中写入该位置,该文件将被加载到包含该地图的html文件中.问题是当我在浏览器中打开html页面时,它工作得很好,但在JavaFX的Web视图中没有任何反应,我不知道为什么!
这是html文件:
<!DOCTYPE html>
<html>
<head>
<title>Simple Map</title>
<meta name="viewport" content="initial-scale=1.0">
<meta charset="utf-8">
<style>
/* Always set the map height explicitly to define the size of the div
* element that contains the map. */
/*#map {
height: 100%;
}*/
#map{width:100%;height:100%;margin:auto;}
/* Optional: Makes the sample page fill the window. */
html, body {
height: 100%;
margin: 0;
padding: 0;
}
</style>
</head>
<body>
<div id="map"></div>
<script>
var map;
var marker;
// Multiple Markers
var markers = [];
var pos …通过使用Java Scripting API,我可以在Java中执行JavaScript.但是,有人可以解释我需要添加到此代码中的内容,以便能够调用C中的函数:/Scripts/Jsfunctions.js
import javax.script.*;
public class InvokeScriptFunction {
public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("JavaScript");
// JavaScript code in a String
String script1 = (String)"function hello(name) {print ('Hello, ' + name);}";
String script2 = (String)"function getValue(a,b) { if (a===\"Number\") return 1;
else return b;}";
// evaluate script
engine.eval(script1);
engine.eval(script2);
Invocable inv = (Invocable) engine;
inv.invokeFunction("hello", "Scripting!!" ); //This one works.
}
}
