The first embodiment is as follows: the embodiment provides a map display method of a visual screen, which is used for enabling a map to be matched with the visual screen, and referring to fig. 1 and fig. 2, an outermost container is the visual screen, other icon components are needed for displaying a map page, and according to actual use scene setting, the method specifically comprises the following steps:
s100: acquiring the size of a visual screen, setting the zooming attribute of an outermost container, and reversely determining the zooming attribute of a map container;
specifically, the zoom attribute of the outermost container and the zoom attribute of the map container are set to be opposite, and the zoom attribute is mainly used for keeping the original size of the map and preventing the map from being influenced by the outermost container, so that map blurring caused by zooming in the second process is reduced. By way of example and not limitation, assume that the outermost container scaling attribute value obtained according to the size of the visualization screen is transform: scale (1,0.5), which represents that the overall width of the map is unchanged and the height is reduced by one time when the map is displayed on the visualization screen. Scale (1,2) is added to the map container, so that the map is reversely magnified, the width of the map is unchanged, and the height of the map is magnified by 2 times.
S200: adjusting a zooming label of a map page according to the zooming attribute of the map container to obtain zooming parameters of the map page;
in the above steps, the Zoom tag is a setZoom tag, and by way of example and not limitation, taking the version 2.0 of the grand map as an example, a Zoom attribute for setting a Zoom-out or Zoom-in scale of the map by a developer through the setZoom tag is provided, where the Zoom attribute is a proprietary attribute of the IE browser, that is, a map page where the map page is located, and it can set or retrieve the Zoom scale of an object. Therefore, the setZoom interface is called when the zoom tab of the map page is adjusted.
S300: setting an initial zooming attribute of a map container, and obtaining a zooming reference value and a floating coefficient of the map page;
specifically, the initial zoom attribute of the map container is set such that the map container is zoomed in length and width in equal proportion. That is, the zoom scale is 1:1, as in the foregoing example, the maximum size of the map is 1920 × 1080, the initial zoom attribute is transform: scale (1,1), the zoom parameter of the map page at this time can be obtained by the getZoom method provided by the grand map, that is, the reference value of the map page is 11.2, and meanwhile, the floating coefficient 1.1 can also be directly obtained by the getZoom.
S400: zooming the outermost container for multiple times, synchronously obtaining zooming parameters of the map page, and generating a zooming attribute relation function of the zooming parameters of the map page and the map container according to the zooming reference value and the floating coefficient of the map page;
specifically, the outermost container is zoomed for multiple times, the outermost container can be operated through a developer debugging tool of a browser where the map page is located, the attribute value of the map container is set to transform: scale (1,2), the setZoom tag is called to zoom at the moment, and the zoom parameter of the map page at the moment is obtained to be 10.1 according to the getZoom. Other scaling ratios can be selected to scale the outermost container multiple times, so that for convenience of calculation, the scaling attribute is transform: scale (1,0.25), and the scaling attribute of the map container is synchronized to transform: scale (1,4), and the scaling parameter of the acquired map page is about 7.89. For more accurate calculation, the scale may be continuously adjusted to obtain more scaling parameters.
For clarity, the following table is given as an example:
based on the zoom attribute of the map container and the zoom parameter of the map page in the above table, a functional relationship between the two can be derived, where X is 11.2- (a-1) × 1.1, where 11.2 is the zoom reference value of the map page, a is the maximum value of the length and width in the zoom attribute scale (1,1) of the map container, 1 is the reference zoom scale, 1.1 is the floating coefficient, and X is the zoom parameter of the map page, where the zoom reference value and the floating coefficient of the map page can be adaptively changed according to different map pages and different visualization screens.
Based on the above, the relationship function between the zoom parameter of the map page and the zoom attribute of the map container can be obtained as follows:
X＝μ-(a-1)×θ
wherein X is a zooming parameter of a map page; mu is a zoom reference value of the map page; theta is a floating coefficient; a is the greater of the length or width scale in the map container scale attribute.
In this embodiment, the scaling of the outermost container is performed multiple times, and a relationship function between the scaling parameter of any map page and the scaling attribute of the map container in the display process of the visual screen is obtained, that is, the scaling attribute of the outermost container is calculated according to the size of the visual screen and the display parameter of the map page, then the scaling attribute of the map container is determined, and finally the scaling parameter of the map page is obtained, and the map page is scaled, so that the map is displayed on the visual screen clearly and in a normal scale.
Further, in this embodiment, in order to further improve the accuracy of obtaining the zoom reference value and the floating coefficient by modifying the zoom attribute of the map container by using the setZoom tag, after setting the initial zoom attribute of the map container and before obtaining the zoom reference value and the floating coefficient of the map page, the method further includes: and carrying out zoom adjustment on the map page, and synchronously updating the zoom label of the map page, wherein the zoom adjustment can be manual adjustment or setting an instruction so as to keep the initial zoom attribute of the map container at 1:1, thereby reducing the problem of poor adaptation effect caused by errors.
S500: obtaining display parameters of a map page, calculating the zooming attribute of the target outermost container, and dynamically calculating the zooming parameter of the target map page based on the zooming attribute of the target outermost container according to the relation function so as to display the map on a visual screen.
In the above step, as described above, after obtaining the display parameters of the map page, the length-width scaling ratio (i.e. the ratio of the size of the visual screen to the size of the map in length and width) can be calculated according to the size of the visual screen, and the scaling ratio is the scaling attribute of the outermost container, so that the scaling attribute of the map container is reversely calculated, and finally, the scaling parameters of the target map page are obtained according to the above relation function, and after scaling the map according to the scaling parameters of the target map page, the map is displayed on the visual screen, so as to achieve the effect of synchronous scaling adaptation. By independently setting the zoom parameters of the map page, compared with the conventional visual screen which directly sets the zoom scale according to the size, the embodiment can solve the problems of map distortion and too large focus offset of the central point.

X＝μ-(a-1)×θ
