Under the condition that the number of pages of the electronic document is large, the number of pages corresponding to 1 degree on the circular arc of the first circle is also large, and therefore page turning accuracy and user experience can be affected. In order to solve the problem, the invention utilizes the combination of the second circle and the smaller page number range to improve the page turning accuracy. Specifically, the technical scheme provided by the invention can further comprise the following steps a-e on the basis of executing the steps 101-105:

Fig. 2 is a second flowchart of the method for turning pages of an electronic document according to the present invention, as shown in fig. 2, the method includes steps 201 to 208, in which:
in step 201, a canvas and a coordinate system are created.
Specifically, the size and position of an electronic document page are obtained, the equipment parameters of the electronic equipment and the size and position of a display area of the electronic equipment are obtained, a square electronic canvas B with a side length L is created according to the parameters, the electronic canvas B is added to the display area, a coordinate system T is created, and the center of the electronic canvas B is set as an origin of the coordinate system. And acquiring coordinates of the pressed position of the user on the electronic canvas B in real time, and converting the coordinates into a point P0 on a coordinate system T.
Step 202, acquiring the number of pages of the electronic document, and creating a second circle.
Specifically, the page number pageCount of the electronic document is acquired, startpage=1, endpage=pagecount is set, the side length L of the electronic canvas B is used as a second circle, and the circumference C1 is calculated by using the diameter of the circle O1. The circle center of the circle O1 is coincident with the center of the electronic canvas B, the size and the position of the circle O1 are determined, the circle O1 is drawn on the electronic canvas B, and the circle O1 can be temporarily set to be in a hidden state for standby.
Step 203, creating a first circle.
Specifically, one half of the side length L of the electronic canvas B is taken as the diameter of a first circle, such as circle O2. And (3) coinciding the center of the circle O2 with the center of the electronic canvas B, determining the size and the position of the circle O2, drawing the circle O2 on the electronic canvas B, and obtaining 360 degrees of the total circle. Fig. 3 is one of operation diagrams based on a first circle provided by the present invention, and fig. 4 is a second of operation diagrams based on a first circle provided by the present invention, referring to the first circle shown in fig. 3 and 4, a user may perform a selection operation, such as a touch operation, a press operation, or a slide operation, on an electronic canvas. The user may move the selected location multiple times, the direction of movement may be clockwise or counter-clockwise.
And 204, constructing a start-stop page number array ArrayO1.
Specifically, two circles are regarded as line segments having starting points, a point directly above the two circles is regarded as the starting point of the line segment, the points on the line segment correspond to the page numbers of the electronic document, and numbers of page numbers (1 to pageCount) are placed in the start-stop page number array ArrayO1 in a clockwise order from small to large.
Step 205, calculating the corresponding degree according to the coordinates of the operation position of the user, calculating the proportion of the degree to the whole first circle, calculating the page number and displaying.
Specifically, the center of the circle O2 and the point P0 pressed by the user are connected by a straight line, the straight line is extended until the point P1 is obtained by intersecting the circle O1, the straight line is extended until the point P2 is obtained by intersecting the circle O2, the number of GP1 may be displayed near the point P1, and/or the number of GP2 may be displayed near the point P2. And if the number of degrees D2 is 0 degrees right above the circle O2, the number of degrees D2 can be calculated through the coordinates of P0 or P2, the percentage of the current pressing point of the user to the circular arc of the whole circle O2 is obtained after the number of degrees D2 is divided by 360 degrees, the percentage 2 is multiplied by the number of pages (pageCount), the number of pages GP2 which the user wants to turn is obtained by cutting off the number of decimal points to take an integer, the number GP2 is displayed in a display interface, and the page turning of the electronic document is skipped to the page GP2.
Step 206, the user continuously moves the click position P0 and then continuously repeats step 205 to update GP2, and when the user no longer clicks, the number of pages is not updated, the electronic document is jumped to the updated number of pages, and step 207 is selectively executed.
Fig. 5 is a schematic diagram of a page turning principle based on circle O2, referring to fig. 5, assuming that a certain electronic document has 600 pages in total, when the degree corresponding to the operation position of the user is 45 degrees, the target page number=600 pages×45 degrees/360 degrees=75 pages, and the electronic document turns/jumps to the 75 th page; when the user moves the clicked position, assuming that the degree corresponding to the new operation position is 60 degrees, the target page number=600 pages is 60 degrees/360 degrees=100 pages, and the electronic document turns/jumps to page 100.
In the case that the number of pages of the electronic document is large, for more accurate positioning and page turning, whether to execute step 207 may be selected according to whether the number of pages of the electronic document is excessive and a preset trigger condition. For example, when the electronic document having the number of pages of 1800 pages or more is determined to be an electronic document having a large number of pages, and P0 is closer to the circle O1 and farther from the circle O2, the trigger condition is satisfied, and step 207 is executed.
Step 207, precisely locating the page number by using the degree ratio of the second circle and the small-range start-stop page array.
In particular, when the number of pages of a document far exceeds 360 pages, a manner of using only the degree of circle O2 times the total number of pages may not be accurately located to a certain page. At this time, the circle O1 can be displayed, and the range of start and stop page numbers is reduced by using the degree proportion of the circle O1 (namely, the second circle), so that the number of pages can be more accurately positioned by using the degree proportion of the second circle and the start and stop page number array in a small range, and the page turning accuracy is improved. And pausing the jump or displaying the GP2 page according to the trigger condition, and taking over the GP2 by the GP1 corresponding to the circle O1.
The circle O1 is utilized to reduce the page number range and improve the page turning accuracy. Adding and subtracting a number from the target page number calculated by the circle O2 to form an array with a first element and a last element as a start page, wherein the number in the range of the start page is clockwise evenly distributed on the circle O1 from small to large, a plurality of numbers corresponding to each degree are obtained according to 360 degrees and the number of the elements of the array, the number of the point pressed by the user in the circle O1 is multiplied by the number corresponding to each degree to obtain the position of the point in the array, and the position is added with the start page number to obtain the target page number of the user.
For example: the change start page=gp2-5×pd, the change end page=gp2+5×pd, and the value of PD may be equal to the ratio of the number of pages of the electronic document to 360 degrees, and the value of PD may be set based on an empirical value or set by a user. After the array ArrayO1 is emptied, the numbers from startPage to endPage are stored in the array ArrayO1 in a descending order, and the Length of the array ArrayO1 is calculated. Dividing 360 degrees by Length to obtain a number of degrees number occupied by each number in the array ArrayO1 on a circle O1, connecting a pressing site P0 of a user with the circle center of the circle O1, calculating the number D1 of the P0 on the circle O1, dividing the number D1 by the number occupied by each number, rounding to obtain an Index value Index, wherein the Index value represents the position of the number in the number array, calculating to obtain a skip page number GP1=startPage+index, and directly taking elements positioned in the Index position in the array, namely GP1=ArrayO1 [ Index ], and displaying or skipping to GP1 on an interface.
Fig. 6 is a schematic diagram of page turning principle based on circle O1 and circle O2, referring to fig. 6, assuming that a certain electronic document has 3600 pages altogether, when the degree corresponding to the operation position of the user is 45 degrees, the determined GP 2=3600 pages based on circle O2 is 45 degrees/360 degrees=450 pages, pd=3600 pages/360=10, the start page number (startPage) =gp 2-5×pd=400, the end page number (endPage) =gp2+5× pd=500, the intermediate page number (middlePage) = (endPage-startPage)/2=500, index= (500-400+1)/360×45=12.6, and Index is equal to 13 after rounding operation, gp1=400+13-1=412 pages, and the elements located in 13 in the rounding group are gp1=Arrayo1 [13] =412 pages, so that the target page on which the electronic document can be obtained is 412 pages.
