Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a flowchart of a video automatic playing method implemented based on a React frame according to an embodiment of the present invention. As shown in fig. 1, the method for automatically playing a video based on an React frame specifically includes the following steps:
and S101, packaging the original video assembly in the page to obtain the React video assembly.
The React frame may not be limited by the frame of the system itself, such as an android system, an IOS system, etc., and may be used. In this embodiment, the page is described by taking a web page of an application as an example. In each application installed on the mobile terminal, web pages of applications of different system frameworks can use the React framework to realize automatic playing of videos in the pages.
And packaging the original video component based on the React frame by using modes such as inheritance, reconstruction and the like, and packaging the original video component into the React video component based on the React frame on the premise of keeping function realization, attribute setting and the like in the original video component. The React video component is added with first appointed attribute information of video elements on the basis of realizing all functions, attribute setting and the like of the original video component. The first specified attribute information can facilitate directly acquiring all video elements in the page. Specifically, the first specified attribute information is a ref attribute of fact. A ref attribute is set in the video element. < video ref ═ this. Meanwhile, after video elements are added to the page by using the following codes, when the video elements are instantiated, the ref attribute of the video elements is assigned:
refVideo＝(elem)＝>{
this.videoElem＝elem
}
the ref attribute of each video element is instantiated to a specific video element. For example, video element aa is instantiated, its ref attribute is assigned as aa, video element bb is instantiated, and its ref attribute is assigned as bb, etc.
In step S102, all video elements are acquired by using the first specified attribute information.
When all the video elements in the page are acquired by using the first specified attribute information in the read video component, specifically, each video element in the page has a ref attribute, and each video element in the page having a ref attribute can be acquired by using this. If video elements aa and bb are included in the page, video elements aa and bb may be obtained using this. Further, the obtained video elements may be stored in an array, and the video elements are sequentially stored according to an instantiation sequence of the video elements or a page setting sequence, and the like.
And step S103, sequentially judging whether each video element has a video element positioned in the current window of the page.
And sequentially judging the acquired video elements according to the sequence in the array, specifically, judging whether each video element is positioned in the current window of the page.
Specifically, the top height value of the current window of the page and the height value of the current window of the page are obtained, and the bottom height value of the current window of the page is obtained through calculation. For example, the top height value of the current window can be obtained by using the window. The bottom height value of the current window is equal to the top height value of the current window plus the height value of the current window itself.
And sequentially acquiring the top height value of each video element and the self height value of each video element, and calculating to obtain the bottom height value of each video element. If the video element top height value is equal to the offset height value of the video element plus the offset height values of all its ancestor elements (traversing all other elements in the page above the video element tag, other elements above the video element tag can be obtained using methods such as obtaining the video element's parents). The self height value of the video element is obtained by using the offset height method. The bottom height value of the video element is equal to the top height value of the video element plus the self height value of the video element.
And sequentially judging whether the top height value of each video element is smaller than the top height value of the current window of the page or not and whether the bottom height value of each video element is larger than the bottom height value of the current window of the page or not, judging that the video element is positioned in the current window of the page when the video elements meet the two conditions simultaneously, and executing the step S104.
And step S104, playing the first video element positioned in the current window.
When the video elements are played, the problems of disordered pictures, noisy sound and the like when pages are displayed due to the fact that a plurality of video elements are played simultaneously are avoided, and only the first video element located in the current window is played. When judging that only one video element is positioned in the current window at present, playing the video element; when a plurality of video elements are judged to be positioned in the current window, only the first video element is played; or when the sequential judgment is carried out, when the video element is judged to be positioned in the current window, the judgment is not continued, and the video element is played. The specific configuration may be set according to the implementation, and is not limited herein.
The React video component also has second specified attribute information for specifying a video state of the video element. Such as adding a command attribute on the basis of the original video component for specifying the video state of the video element. When the video element is played, the second specified attribute information of the video element is modified into a playing state. Such as setting the command attribute to play. And calling a video state modification command of the original video component according to the second specified attribute information, and changing the video state of the video element into a playing state. For example, in the read video component, the value of the command attribute is obtained through nextProps in the shouldComponentUpdate method, and when the value is play, the play method in the original video component is called to realize the playing of the video element.
According to the automatic video playing method based on the React frame, provided by the invention, the original video component in the page is encapsulated to obtain the React video component; the React video component has first specified attribute information of the video elements; acquiring all video elements by using the first specified attribute information; sequentially judging whether each video element has a video element positioned in a current window of the page; and if the video element is judged to be positioned in the current window of the page, changing the video state of the first video element positioned in the current window into a playing state. The invention utilizes the React frame to encapsulate the original video assembly, on one hand, the video automatic playing method realized by the method is not influenced by the system frame, the code can be reused in different systems, the labor development cost is reduced, and the development time is saved. On the other hand, all video elements can be acquired at one time by utilizing the first specified attribute information in the React video component, so that all video elements can be conveniently judged, the first video element in the current window can be accurately determined, and the video can be automatically played by changing the video state.
Fig. 2 is a flowchart illustrating a video automatic playing method implemented based on a React frame according to another embodiment of the present invention. As shown in fig. 2, the method for automatically playing a video based on the fact frame specifically includes the following steps:
step S201, packaging the original video assembly in the page to obtain a React video assembly.
In step S202, all video elements are acquired using the first specified attribute information.
Step S203, sequentially determining whether there is a video element located in the current window of the page in each video element.
And step S204, playing the first video element positioned in the current window.
The description of the above steps refers to the description of the embodiment in fig. 1, and is not repeated herein.
Step S205, monitoring a scroll event of a scroll bar in a current window of the page, and determining whether the scroll bar of the current window is scrolling.
Adding a monitoring event to the scroll bar, for example, adding an addEventListener method to monitor the scroll event of the scroll bar, triggering the addEventListener when a user drags or pulls the scroll bar or the scroll bar moves up and down or the like, so as to monitor the scroll event of the scroll bar, determine that the scroll bar of the current window is rolling, and execute step S206.
In step S206, the video state of the video element is changed to the paused state.
Due to the fact that the scroll bar of the current window is scrolled, the video elements may not be located in the current window completely, and at the moment, the video elements are continuously played, and the display effect is not started for the user. And in the process of the current window rolling, the display effect of continuously playing the video elements is poor. Therefore, when it is determined that the scroll bar of the current window is scrolling, the video state of the video element is changed to the paused state. Specifically, the second specified attribute information of the video element is modified into a pause state, and the command attribute is set to stop. And calling a video state modification command of the original video component according to the second specified attribute information, and changing the video state of the video element into a pause state. And calling a stop method in the original video component to realize pause playing of the video element when the value of the command attribute is stop.
And step S207, judging whether the scroll bar of the current window stops rolling at preset time intervals.
After the scroll bar of the current window is monitored to be scrolled, it is necessary to continuously judge when the scroll bar stops scrolling. Here, after the step S205 determines that the scroll bar of the current window is scrolling, the step S may perform the step of determining whether the scroll bar of the current window stops scrolling by using a callback function such as a scroll bar scroll event.
And after the scroll bar of the current window stops scrolling, re-executing the step S203, and determining whether a video element is located in the current window of the page, and if so, changing the video state of the video element to a playing state. Further, if it is determined that the video element is located in the current window of the page and the video state of the video element is the pause state, that is, the video element is playing before the scroll bar is scrolled, and when the scroll bar is scrolled, the video state of the video element is modified to the pause state, so that the video element is paused. When the scroll bar stops scrolling, the video element is still located in the current window of the page, and at this time, the video state of the video element can be changed into a playing state, so that the video element is played at a breakpoint. The breakpoint playing records the position of the video element when the video element is paused, so that the video element can continue to be played downwards according to the position when the video element is paused, and the video element is not played from the beginning again. Compared with the prior art that the video elements are played from the beginning again when the playing state is changed, the user can continue to watch the content behind the video elements, the watching habit of the user is better met, the user does not need to spend time to watch the watched content again, or the user needs to manually adjust the watching progress and the like, and the watching experience effect of the user is improved.
When judging whether the scroll bar of the current window stops scrolling at every preset time, specifically, after monitoring a scroll event of the scroll bar, recording an initial position value of the scroll bar in the current window. And then acquiring the current position value of the scroll bar in the current window at preset time intervals. Here, the timer may be used to perform the timing, and the current position value of the scroll bar in the current window is obtained. If the set-up timer is preset for a time interval of 200 milliseconds. The current position value of the scroll bar in the current window is acquired every 200 milliseconds. It is determined whether the initial position value is equal to the current position value. If the initial position value is equal to the current position value, the scroll bar is not rolled, and the scroll bar of the current window is judged to stop rolling. And if the initial position value is not equal to the current position value, namely the scroll bar still rolls, updating the initial position value to the current position value. And continuously utilizing the timer to obtain the current position value of the scroll bar in the current window at intervals of preset time, and judging whether the initial position value is equal to the current position value or not until the initial position value is equal to the current position value, namely the scroll bar stops rolling.
Further, when it is determined at preset intervals whether the scroll bar of the current window stops scrolling, in order to prevent the scroll bar from frequently executing when it is determined whether the scroll bar of the current window stops scrolling during the scrolling process, a timing execution flag value may be set, and the default timing execution flag value is not executed. When judging whether the scroll bar of the current window stops, firstly detecting whether the timing execution mark value is unexecuted. If the timing execution flag value is not executed, that is, no timer is currently processing to determine whether the scroll bar stops scrolling. The initial position value of the scroll bar in the current window can be recorded, and whether the scroll bar of the current window stops rolling or not is judged when the current position value of the scroll bar in the current window is obtained at intervals of preset time. Meanwhile, the timer execution flag value is set to be in execution. At this time, if a scroll bar triggers a scroll event, the callback function executes to judge whether the scroll bar of the current window stops rolling, and since the timing execution flag value is in execution, that is, whether the scroll bar stops rolling is judged at present, the timer is not established again, and the current position value of the scroll bar in the current window is obtained at preset time intervals according to the timing of the current existing timer for judgment, so that the data waste caused by the establishment of repeated judgment of a plurality of timers is avoided. And after the scroll bar of the current window stops rolling, setting a timing execution marking value as unexecuted, and eliminating the timer.
According to the automatic video playing method based on the React frame, the React frame is utilized to encapsulate the original video component, so that the automatic video playing method realized by the method is not influenced by the system frame, codes can be reused in different systems, the labor development cost is reduced, and the development time is saved. Meanwhile, the scroll bar scrolling event of the current window is monitored, and when the scroll bar is scrolling, the playing of the video elements is paused, so that the bad watching effect in the scroll bar scrolling process is avoided. And after the scroll bar stops scrolling, when the video element is judged to be positioned in the current window, the video element is played according to the breakpoint and is not played from the beginning again. The user can continue to watch the content behind the video element, so that the watching habit of the user is better met, the user does not need to spend time to watch the watched content again, or the user needs to manually adjust the watching progress and the like, and the watching experience effect of the user is improved.
