Description
Technical Field
The invention relates to the technical field of computers, in particular to a method, a medium and equipment for processing a key event.
Background
In an actual IPTV application, a user operates by moving a focus through up, down, left, and right direction keys of a remote controller, and for a general-purpose browser, a response flow of a key event generally includes two types, one is from a web page side to the browser side, and the other is from the browser side to the web page side. For browser-end products oriented to PCs and smart phones, users usually click a target element or a hyperlink directly through a mouse or a touch screen, and response processing of a case event is only completed by the browser end, and a situation that a web page end performs processing by itself and/or browser-end cooperation processing may be required in an IPTV service, so that a general browser end cannot meet special requirements for a key processing process in the IPTV service.
Moreover, after the browser end receives the key event, the browser end does not know whether the webpage end has performed response processing on the key event or not, and does not know that the key event will not be processed again by the webpage end when flowing to the webpage end, so that a situation that the webpage end and the browser end both process the same key event may be caused, which may cause an error situation on the page, and seriously affect user experience.
The browser end customized for the IPTV service has a high customization cost to meet special service requirements, and has a large workload during later modification, which causes problems of poor adaptability and flexibility, and cannot meet requirements of the IPTV service.

The invention provides a method, a medium and a device for processing a key event, which judge whether the key event is processed by a webpage end or not through intelligent decision of the key event, can automatically distinguish the processing flow and path of the key event through delayed processing of the key event on the basis, solve the problem of wrong response of the key event in a page and improve the flexibility and the adaptability of a product. Embodiments of the present invention will be described below with reference to the drawings.
Fig. 1 is a flowchart illustrating a method for processing a key event according to a first aspect of the present invention. As shown in fig. 1, a method for processing a key event according to a first aspect of the present invention includes the following steps:
step S101: acquiring a key event sent by a user, and pressing the key event into a stack;
step S102: transmitting the key event pressed into the stack to a webpage end;
step S103: if the webpage end does not process the key event pressed into the stack, the key event is popped up;
step S104: and sending the popped key event to a browser end.
Step S105: and if the webpage end processes the key event pressed into the stack, discarding the key event.
In the present invention, the execution body of the processing method of the key event may be a browser end in the IPTV field. The IPTV field is the field of interactive network television.
The browser end in the IPTV field is started to display a webpage, unlike a page opened in a pc browser end, the page is more like a desktop of a mobile phone and has no address input field, and the navigation of the whole page is controlled by a remote controller.
Specifically, the flow process of the key event mainly includes two types, the first type is from the web page side to the browser side, and the other type is from the browser side to the web page side. In an actual IPTV service, because the browser does not know whether the key event has been responded and processed by the web page, or the key event will not be responded and processed by the web page after the browser responds and processes, there may be a problem that the web page and the browser respond and process the key event respectively, which may cause an error, for example, a problem that a focus skips some controls, or the focus cannot be moved to some controls.
In the first case, the keystroke event flows from the web side to the browser side. In order to avoid that after the browser end acquires the key event sent by the user, the browser end firstly needs to judge whether the webpage end has responded and processed the key event, if the webpage end has responded and processed the key event, the key event is discarded to stop the key event from continuing flowing to the browser end, the browser end does not respond and process the key event any more, and the specific discarding method is to set an internal member variable m _ defaultHandled of the key event to true to indicate that the key event is processed.
If the webpage end does not respond and process the key event, the key event is continuously sent to the browser end so that the browser end can respond and process the key event, a filtering mechanism is arranged in the browser end, the key event is analyzed and judged layer by layer, if the key event belongs to the event, corresponding processing is carried out, and if the key event does not belong to the event, the key event is continuously transmitted to the next layer. If the key event is passed to the last layer and is not processed, the key event is discarded.
Further, in the second case, the key event flows from the browser end to the web page end, in this case, since the key event is already responded and processed by the browser end once when flowing out from the browser end, when it flows to the web page end, the web page end may respond and process the key event again, which may cause the same key event to be responded and processed by the browser end and the web page end respectively, so that the key event is responded and processed twice, which inevitably causes the above error condition.
Therefore, after the browser obtains the key event sent by the user, because the browser does not know whether the key event has been responded and processed by the web page, or the key event will not be responded and processed by the web page again after the browser responds and processes, the key event may be responded and processed by the web page and the browser at the same time, and the key event is processed twice. Therefore, the scheme provided by the invention is as follows: after the browser end receives the key event, the browser end firstly does not process the key event, but presses the key event into the stack so as to delay the response and the processing of the browser end to the key event, the key event pressed into the stack is firstly sent to the webpage end, and if the webpage end responds and processes the key event pressed into the stack, the key event is directly discarded according to the situation; and if the webpage end does not respond and process the button event pushed to the stack, the button event is pushed out of the stack to be sent to the browser end for the browser end to respond and process.
Furthermore, in order to avoid pressing too many key events into the stack and affecting the response and processing speed of the browser to the key events, after the browser receives the key events of the user, the browser first needs to determine which of the above situations the flow of the key events is. If the key event belongs to the first situation, i.e. the key event flows from the web page to the browser, the key event is directly sent to the web page without being pressed into the stack, so as to execute the first situation. If the key event belongs to the second situation, namely the key event flows into the webpage end from the browser end, the key event is pressed into the stack to delay the response and the processing of the browser end to the key event, the key event pressed into the stack is sent to the webpage end, and then the first situation is executed.
Optionally, an embodiment of the present application provides a method for determining that the webpage end has processed the button event pushed onto the stack, which specifically includes the following steps:
acquiring the state of a focus control and/or the request state of page resources;
and if the state of the focus control and/or the request state of the page resource changes, determining that the key event is processed at the webpage end.
In order to distinguish whether the key event is responded and processed at the webpage end, the method and the device intelligently judge the response processing condition of the key event at the webpage end by monitoring the state of the control for acquiring the focus and the page resource request state.
Specifically, before the key event is transmitted to the web page end, the browser end records control information of the current acquisition focus, and after the key event passes through the web page end, the browser end records the control information of the current acquisition focus again. If the control for acquiring the focus recorded in the two previous and next times is changed, the key event can be considered to be responded and processed by the webpage end.
Specifically, the obtaining, by the browser, control information of the focus before and after the key event processing includes: firstly, the webpage acquires the key event which is transmitted through the inner core of the browser end, so that the browser end can master two time stages before the key event is processed and after the key event is processed. When the browser-side kernel receives a remote controller key event sent by a user, before the key event is about to be sent to the webpage end, the browser-side can acquire information of a current focus control once, then transmit the key event to the webpage for processing, and after the key event flows out of the webpage end, the browser-side acquires information of the current focus control once again. If the focus controls obtained in the two times are changed, the webpage end can be considered to respond and process the key event.
The focus control is changed, that is, the control for acquiring the focus in the page is shifted, for example, two elements are provided in the page, one is < a > and the other is < input >, and when the focus control is moved from < a > to < input >, the focus control is considered to be changed.
On the other hand, after the key event flows into the web page, the browser side monitors the situation of the page for the resource request in real time, and if a request for a new page, a request for a url of a new frame, or the like occurs, it is also considered that the key event is responded and processed by the web page side.
Similar to the method for detecting the focus control state, detecting the page resource request state also detects whether the web page sends a resource request of a new page or a new frame to the browser end in the time period from before the browser end transmits the key event to the web page end to after the web page end flows out. If yes, the key event is considered to be responded and processed by the webpage end.
The detection of the two states is and/or relationship, wherein if one of the states detects that the webpage end processes the key event, the key event can be determined to be processed and responded by the webpage end without being sent to the browser end.
According to the processing method of the key event, whether the key event is processed by the webpage end or not is intelligently judged through the intelligent decision of the key event, and the browser end carries out delayed processing on the key event, so that the processing flow and path of the key event can be automatically distinguished, the problem that the key event in the page cannot be correctly responded is solved, the key event can be perfectly distinguished and distributed, the requirements of IPTV service specifications are met, and the flexibility, intelligence and competitiveness of products are improved.
