onQuery

public boolean onQuery(CefBrowser browser,
                       CefFrame frame,
                       long queryId,
                       java.lang.String request,
                       boolean persistent,
                       CefQueryCallback callback)

从接口复制的说明: CefMessageRouterHandler

Called when the browser receives a JavaScript query. (当浏览器收到JavaScript查询时调用。)

指定者:

onQuery 在接口中 CefMessageRouterHandler

参数:

browser - The corresponding browser. (-相应的浏览器。)

frame - The frame generating the event. Instance only valid within the scope of this method. (-生成事件的框架。实例仅在此方法的范围内有效。)

queryId - The unique ID for the query. (-查询的唯一ID。)

persistent - True if the query is persistent. (-如果查询是持久的，则为true。)

callback - Object used to continue or cancel the query asynchronously. (-用于异步继续或取消查询的对象。)

返回:

True to handle the query or false to propagate the query to other registered handlers, if any. If no handlers return true from this method then the query will be automatically canceled with an error code of -1 delivered to the JavaScript onFailure callback. (如果为True，则处理查询；如果为false，则将查询传播到其他已注册的处理程序（如果有）。如果没有处理程序从此方法返回true，则查询将被自动取消，并向JavaScript onFailure回调传递错误代码-1。)

onQueryCanceled

public void onQueryCanceled(CefBrowser browser,
                            CefFrame frame,
                            long queryId)

从接口复制的说明: CefMessageRouterHandler

Called when a pending JavaScript query is canceled. (取消待处理的JavaScript查询时调用。)

指定者:

onQueryCanceled 在接口中 CefMessageRouterHandler

参数:

browser - The corresponding browser. (-相应的浏览器。)

frame - The frame generating the event. Instance only valid within the scope of this method. (-生成事件的框架。实例仅在此方法的范围内有效。)

queryId - The unique ID for the query. (-查询的唯一ID。)
