| Providing the location-based service also has become to the feature.The technology uses the mobile communication of mobile device,combined with the global positioning system,access to geographic location of users' devices and dig useful information from the location information.It combined with the rapid spread of mobile internet information platform make these location information become value-add data.The system that based on cross-platform development framework Apache Cordova and IONIC hybrid application development framework builds a quick deployment solution includes Android and IOS mobile platform applications,etc.When users use the system to make their orders,the system will send the notification according to the location.The system mainly developed by Web development technologies,such as HTML5,CSS3 and JAVASCRIPT language.It is very popular and relatively low barriers to entry.There are so much active development communities,open source libraries.Through the page load performance test of the system application,it can be cached locally after first load of page.Development with MVC framework of AngularJS make the templates load and render on demand.It can improve page load performance further.The system provides an answering and waiting for selection mechanism to handle events demand response in order.It also can reduce the waste generated by response data.The publisher can choose who to finish that order.As a result of using Cordova which provides a number of API for calling native application APIs,it can obtain the users' geographic location by calling the location API of Baidu map.The system also records the potential responders and decides the sequence for deriving by calculating the distance between the two locations.Apache Cordova and IONIC provide a convenient way to deploy cross-platform applications by simply adding different platforms.After recompiling,it is easy to get the generated binary files for distribution. |
