Embodiment two:
In the scheme of the embodiment of the present invention one, map section is sent to client by rendering server, by client, the map received section is combined into electronic chart and shows, the electronic chart that conveniently user customer is shown operates, the embodiment of the present invention two does further process to the electronic chart that client is shown on the basis of embodiment one, and carries out the operations such as such as public transportation enquiry to the electronic chart after process.
As shown in Figure 5, be the process flow diagram of the present embodiment two, comprise the following steps:
Step 201: client receives map that rendering server sends and cut into slices and after being combined into electronic chart, obtains the general point information of the general point that mark that the map that receives cuts into slices comprises from rendering server.
The specific implementation process of this step 201 includes but not limited to following two kinds of modes:
First kind of way:
Client is after being combined into electronic chart, determine each map section mark comprised in the electronic chart of this current display, and will determine that map section mark is sent to rendering server, the general point information represented by general point mark corresponding for the map determined section mark is sent to client by request rendering server.
Such as: client sends to rendering server the request message including section mark and is: http://xxx.mapabc.com? tile=6741.3102,6741.3103,6741.3104 & z=13 & rid=782699, wherein, 6741.3102 a section mark is.
The second way:
Client is after being combined into electronic chart, and rendering server determines that this map sending to client is cut into slices, and the general point information of the general point comprised of being cut into slices by described map is sent to client.
After client receives the general point information of rendering server transmission, can map section be unit, store general point information in this locality.
Step 202: client monitor MouseMove (mouse displacement) event, judge mouse whether be arranged in client show electronic chart play up frame region, if so, then execution step 203; Otherwise, proceed MouseMove and monitor.
Owing to containing the displaying mark of multiple general point in the electronic chart that client is shown, that is, what have multiple general point in the electronic chart of displaying plays up frame, therefore, in this step 202, the region of playing up frame shared in electronic chart can be referred to as to play up frame region.
Particularly, in step 202., when client monitors mouse displacement event, judge whether the position at the current place of mouse belongs to arbitrary step playing up frame region in electronic chart and comprise:
The first step: obtain the positional information in the electronic chart at the current place of mouse.
Second step: determine the map section mark that described positional information is corresponding.
3rd step: judge whether this positional information belongs in the scope that the general point represented by general point mark corresponding to described map section mark cover, that if so, then determines that mouse is arranged in the electronic chart of displaying plays up frame region; Otherwise that determines that mouse is not arranged in the electronic chart of displaying plays up frame region.
Step 203: client is according to the general point information obtained from rendering server, determine the general point information played up represented by frame region at the current place of mouse, and judge whether the coordinate (also namely playing up the coordinate of the reference point in frame region) of general point in this general point information exists, if exist, then perform step 205; Otherwise, perform step 204.
In the scheme of this step 203, first client can determine that map section corresponding to position in frame region is played up at the current place of mouse, and then according to the map section mark and general point identify between corresponding relation, determine that the general point information of general point represented by frame region is played up at the current place of mouse.
If the coordinate that reference point in the general point information of general point represented by frame region is played up at the current place of mouse exists, then represent the position at the current place of mouse and play up the reference point in frame region in same map is cut into slices; Otherwise, represent the current position of mouse and play up the reference point in frame region not in same map is cut into slices.
Step 204: client, according to the section of mouse current place map, determines that this plays up the reference point in frame region from cut into slices other maps adjacent cut into slices with this map.
The map section that the section of described adjacent map refers to for splicing electronic chart is in the upper and lower map section in the left and right of described map section in position.
Particularly, when determine the current place of mouse play up position in frame region and this reference point playing up frame region not in same map is cut into slices time, determine that the method that this plays up the reference point in frame region comprises:
The first step: client reads the first general point mark, this first general point mark is that general point corresponding to frame region of playing up determined in the map section at the current place of mouse identifies.
Second step: client reads the general point information identifying like-identified with the first general point from the section of adjacent map.
3rd step: client obtains the reference point coordinate that frame region is played up at the current place of mouse from the general point information read.
Step 205: the reference point playing up frame region at the current place of client determination mouse, and according to this reference point and the size playing up frame region, generate the covering layer playing up frame region described in covering.
In this step 205, described covering layer has operability, wherein, cover size and the current place of mouse of layer to play up frame size identical, and to change along with the mouse displacement change of playing up frame size extremely.Wherein, the attribute information of described covering layer can be, but not limited to be transparent rectangle frame.
Particularly, client according to the reference point determined and the size playing up frame region, call a Marker function generate described in play up the covering layer in frame region.
