在我的应用程序中,我使用javafx,我有一个显示网站新闻的WebView。当在WebView中单击任何链接时 - 它应该在浏览器中打开,而不是在WebView中打开。我找到了应该在java中运行的代码:
NodeList nodeList = document.getElementsByTagName("a");
for (int i = 0; i < nodeList.getLength(); i++)
{
Node node= nodeList.item(i);
EventTarget eventTarget = (EventTarget) node;
eventTarget.addEventListener("click", new EventListener()
{
@Override
public void handleEvent(Event evt)
{
EventTarget target = evt.getCurrentTarget();
HTMLAnchorElement anchorElement = (HTMLAnchorElement) target;
String href = anchorElement.getHref();
//handle opening URL outside JavaFX WebView
System.out.println(href);
evt.preventDefault();
}
}, false);
}
但诀窍是,我需要将其转换为js(使用nashron引擎)。这就是我现在所拥有的:
pane.lookup("#newsPane").getEngine().getLoadWorker().stateProperty()["addListener(javafx.beans.value.ChangeListener)"](
function(o, ov, nv){
if (nv == javafx.concurrent.Worker.State.SUCCEEDED) {
// Here the things get started
var nodes = pane.lookup("#newsPane").getEngine().getDocument().getElementsByTagName("a");
for(var i=0;i<nodes.getLength();i++){
var node = nodes.item(i);
// I got node, but now i need to cast it to EventTarget, but i didn't find anywhere how to do that
LogHelper.info(node);
// instead of *node* there should be *eventTarget*, also i'm not sure the code above will work even with EventTarget
node['addEventListener("click", javafx.event.EventListener)'](
function(evt){
var target = evt.getCurrentTarget();
var href = target.getHref();
LogHelper.info(href);
evt.preventDefault();
}
)
}
}
});
我找到了一些 Java.to()和 Java.type(),但我没有找到如何使用它们(不确定是否它是可能的)。请问有人给我一些建议吗?

使用JavaScript时,无需转换对象。所以只需在对象上调用函数。
