【摘要】 AJAX是近几年出现的WEB开发新技术,它实现了浏览器和服务器之间的异步交互.目前的网络地质图库系统大多采用传统B/S同步交互技术,由于图库中传输的大多是数据量很大的地质图件,因此经常出现浏览器阻塞现象.将AJAX技术应用到了网络地质图库系统中,实现了浏览器和地质图库服务器之间的异步交互,与采用传统B/S同步方式的网络地质图库系统相比,具有图片刷新快,无页面闪烁的特点.由此研究了基于AJAX的异步地质图实现技术,并实现了基于AJAX的网络地质图库标记系统,不仅扩充了图件标记管理功能,而且成功解决了浏览器阻塞问题.更多还原

【Abstract】 AJAX is a new WEB developing technology occurred in recent years,which has implemented the asynchronous interaction between browser and WEB server.Most WEB geological map system adopts traditional B/S synchronous interaction technology.Users always face the problem of browser block because of the large-volume data of geological map transmitted in the network.Applying the technology of AJAX to the WEB geological map system,implement the asynchronous interaction between browser and WEB geological map server.Compared with traditional WEB geological map system of B/S synchronous mode,the system could refresh WEB page much more rapidly and without flashing.discuss the technology of asynchronous WEB map and develop a WEB geological map tag system based on AJAX,which not only extends the function of tag management but also solves the problem of browser block.更多还原
