Description
Technical field
The present invention relates to the method and system that a kind of Web shows GPS different directions icons.
Background technology
One kind realizes that network service obtains real time GPS in the prior art, using ActiveX Techniques, and this technology exists as follows
Shortcoming：
1) increase interface to control, control installation upgrade problem certainly will be related to, this is very poor for customer experience, and controls
Part downloads installation automatically, and the client machine often having can install failure.
2) ActiveX Techniques are only applicable to IE, it is impossible to which browser-cross uses, and this just constrains user group.
Another kind in the prior art, can be quantified arrive by the different icons in the N number of direction of Art design, foreground according to GPS directions
The icon in some direction, then asks and shows, this prior art has the disadvantage that：
The serious workload for adding art designing and developer, quantifies the icon of N number of angle, and have M kinds if desired
Color is distinguished, then art designing needs to design N*M icon, and developer is also required to handle N*M kind situations.If client is to icon
It is dissatisfied, want to use individual icon, the just further upgrading of art designing, developer's workload.
