In some embodiments, displaying the web page address selection component based on the display information of the web page address selection component and the CSS style file comprises: judging whether the loading of the CSS style file is finished or not; if so, displaying the webpage address selection component based on the definition information of the webpage address selection component and the loaded CSS style file; otherwise, the task displaying the webpage address selection component is placed in a task list, and when the loading of the CSS style file is completed, the webpage address selection component is displayed based on the definition information of the webpage address selection component and the loaded CSS style file. The webpage address selection component can be normally displayed, the display effectiveness of the webpage address selection component is guaranteed, and the situation that the webpage address selection component cannot normally display when the CSS style file is not loaded completely is avoided.
For example, in the process of loading the CSS style file based on the reference address of the CSS style file, because the loaded CSS style file is large and the loading time is long, when the CSS style file is not completely loaded, the web address selection component is directly displayed based on the acquired definition information of the web address selection component and the unloaded CSS style file, which may easily cause the web address selection component not to be normally displayed. Based on the consideration, whether the CSS style file is loaded completely or not can be judged, if yes, the webpage address selection component is displayed based on the definition information of the webpage address selection component and the loaded CSS style file, if not, the CSS style file is continuously loaded, the display task of the webpage address selection component is placed in a task list, and when the CSS style file is loaded completely, the task of displaying the webpage address selection component in the task list is executed, namely, the webpage address selection component is displayed based on the definition information of the webpage address selection component and the loaded CSS style file.
Optionally, before displaying the web address selection component based on the definition information of the web address selection component and the CSS style file, the method further includes: and judging whether first-level region data is acquired, if so, displaying the webpage address selection component based on the definition information of the webpage address selection component and the CSS style file. The first-level region data is used when the webpage address selection component displays. It can be understood that, in order to avoid the delay of the first-level region data in the current display page, the web page address selection address may be displayed after the first-level region data is acquired.
In some embodiments, before displaying the web address selection component based on the definition information of the web address selection component and the CSS style file, further comprising: acquiring width information and height information of a screen of the terminal equipment; calculating the adaptation information of the webpage address selection component according to the width information and the height information; the adaptation information comprises the size of a webpage address selection component and the size of a word size in the webpage address selection component; displaying the web address selection component based on the definition information of the web address selection component and the CSS style file, comprising: and displaying the webpage address selection component based on the definition information of the webpage address selection component, the CSS style file and the adaptation information. The advantage of this arrangement is that the size of the screen of the terminal device can be adapted when the webpage address selection component is displayed, so that the webpage address selection component can be enlarged or reduced in equal proportion under different terminal screen sizes.
Illustratively, width information and height information of a screen of the terminal device for displaying a current display page are acquired, wherein the width information and the height information may include an actual width and an actual height of the screen, and may also include a pixel width and a pixel height of the screen. And calculating the adaptation information of the webpage address selection component according to the width information and the height information according to the set standard screen size. When the proportional relationship between the width information and the width of the standard screen size is inconsistent with the proportional relationship between the height information and the height of the standard screen size, the adaptation information of the web page address selection component can be calculated based on the proportional relationship between the width information and the width of the standard screen size. The adaptation information of the web page address selection component can comprise the size displayed on the screen of the terminal equipment when the web page address selection component is displayed and the size of the word size of characters displayed in the web page address component. And then displaying the webpage address selection component based on the definition display information, the CSS style file and the adaptation information of the webpage address selection component. For example, the style description information in the CSS style file and the adaptation information of the web address selection component may be used as input parameters, a component display method in the definition information of the web address selection component may be called, and the web address selection component may be displayed based on the called component display method.
Fig. 4 is a schematic flowchart of a display method of another web page address selection component according to an embodiment of the present invention, and as shown in fig. 4, the method includes the following steps:
And 406, closing the webpage address selection component, and displaying the region data corresponding to the address selection operation by calling a successful callback function.
In the embodiment of the invention, when the address selection operation acted on the webpage address selection component by the user is detected, whether the region data corresponding to the address selection operation is the last-stage region data is judged, if so, the situation that the region selection does not continue to exist after the region data corresponding to the region selection operation is explained, at the moment, the webpage address selection component can be directly closed, and the region data corresponding to the address selection operation is displayed in the current display page through calling the successful callback function. When the fact that the region data corresponding to the address selection operation is not the last-stage region data is determined, it is indicated that the user may need to continue to select the next-stage region data in the webpage address selection component, the next-stage region data of the region data corresponding to the address selection operation is obtained, and the next-stage region data is rendered into a current display page for the user to select the address. For example, when the web page address selection component includes region data of four levels, i.e., city, district, town, and street, in common, if the region data corresponding to the address selection operation performed by the user on the web page address selection component is the region data of four levels (i.e., the region data related to the street), the web page address selection component is closed, and the region data of four levels selected by the user is displayed in the current display page. If the region data corresponding to the address selection operation acted on the webpage address selection component by the user is second-level region data (namely region-related region data), acquiring town-related region data, and rendering the town-related region data to a current display page for the user to select specific third-level region data.
Optionally, the obtaining of the next-stage region data of the region data corresponding to the address selection operation includes: judging whether next-level region data of the region data corresponding to the address selection operation exists in a cache, if so, acquiring the next-level region data from the cache; otherwise, the next-stage region data is obtained by calling a callback function of the formatting parameter. The method has the advantages that the data stored in the cache can be reasonably utilized, the time for downloading the webpage resources is saved, the speed for acquiring the next-level regional data of the regional data corresponding to the address selection operation can be effectively increased, the flow is saved, and the user experience is improved.
Optionally, the obtaining the next-level region data by calling a callback function of the formatting parameter includes: determining a region grade number of region data corresponding to the address selection operation and a parent-level region number of the region grade number; taking the region grade number and the parent-level region number as input parameters, calling a callback function of the formatting parameter to combine the region grade number and the parent-level region number, and generating a request parameter for acquiring next-level region data; generating an Ajax request according to the request parameters and preset Ajax request configuration parameters, and sending the Ajax request to a server; and judging whether data corresponding to the Ajax request fed back by the server is received within a preset time period, if so, taking the data corresponding to the Ajax request as next-level region data.
In the embodiment of the present invention, the region level number of the region data corresponding to the region selection operation and the parent region number of the region level number are determined, where the parent region number of the region level number can be understood as the previous region level number of the region level number. For example, if the region data corresponding to the region selection operation is the second-level region data, the region rank number of the region data corresponding to the region selection operation is 2, and the parent region number of the region rank number is 1. In another example, if the region data corresponding to the region selection operation is the first-level region data, the region rank number of the region data corresponding to the region selection operation is 1, and if there is no parent region number, the parent region number of the region rank number may be set to 0. And then, taking the region grade number and the parent-level region number as input parameters, calling a callback function of the formatting parameters to combine the region grade number and the parent-level region number, and generating a request parameter for acquiring next-level region data. That is, the callback function of the formatting parameter performs combined processing on the region level number and the parent region number to generate a request parameter for acquiring next-level region data. And generating an Ajax request by using the request parameters of the next-level region data and preset Ajax request configuration parameters, and sending the Ajax request to a server so as to obtain data corresponding to the Ajax request from the server side as the next-level region data.
Optionally, if data corresponding to the Ajax request fed back by the server is received within a preset time period, the data corresponding to the Ajax request is used as next-level region data, and the next-level region data is stored in the cache for subsequent use. Optionally, if data corresponding to the Ajax request fed back by the server is received within a preset time period, the data corresponding to the Ajax request fed back by the server may be used as an input parameter, a callback function of formatted return data is called to format the data corresponding to the Ajax request, and the final data after the data corresponding to the Ajax request is formatted is used as next-level region data, so that the obtained next-level region data meets the format requirement. For example, invoking a callback function for formatting return data to format data corresponding to the Ajax request may include: and generating an array of data corresponding to the Ajax request, wherein each item in the array comprises a key and a value, the key corresponds to the internal value, and the value is used for being displayed in the current display page. Optionally, before the data corresponding to the Ajax request is used as next-level region data, determining whether the data corresponding to the Ajax request is valid, if so, using the data corresponding to the Ajax request as next-level region data, otherwise, closing the web address selection component, and displaying the region data corresponding to the address selection operation, which is performed by the user on the web address selection component, by calling a successful callback function.
