未调用 IFrameElement EventListener
IFrameElement EventListener not being called
我已将 EventListener 添加到 IFrameElement,但它从未被调用。
监听器定义:
EventListener eventListener = (e) {
print("Lisenter clicked.");
};
IFrameElement 定义:
var type = 'click';
IFrameElement element = IFrameElement()
..width = (MediaQuery.of(context).size.width - 400).toString()
..height = MediaQuery.of(context).size.height.toString()
..srcdoc = value
..addEventListener(type, eventListener)
..style.border = 'none';
ui.platformViewRegistry.registerViewFactory(
createdViewId,
(int viewId) => element);
dispatchEvent 定义:
marker.addListener('click', function() {dispatchEvent(new Event("click"));console.log("woot");});
单击标记时,会在控制台中找到 "woot",但我从未看到 "Listener clicked"。我做错了什么?
我得到以下结果:
"marker.addListener('click', function() {dispatchEvent(new MouseEvent('click', {view: window, bubbles: true, cancelable: true }));"
"var o = Object.create(null);"
"o.id = \"${property.id}\";"
""
"console.log(o);"
"window.parent.postMessage(o);"
""
"});\n";
然后我在 window:
上附加一个监听器
window.onMessage.listen((onData) {
// do things
if (messageEvent.data["id"] == property.id) { }
})
