The Design And Impletation Of A Sending-Visa System Based On AngularJS

With the improvement of people’s living standards and life quality, foreign tourism industry has become increasingly popular and hot, so the outbound travel business for the visa requirements have become more sophisticated, and have become a major business of travel companys. According to the survey, the sending visa department of the majority travel companies now manage the consumer visa orders status in the manual recording, updating and maintaining way, not only time consuming, but also prone to error. To address this question, we need to design and implement a true mobile client management platform for visa order.In this paper, on the basis of above background and business needs, we designed and implemented the sending visa system based on We Chat platform. Firstly, we proposed the Angular JS to complete the front-end interface of sending visa system design on the basis of the overall system architecture. Secondly, we design the main modules such as wait-sending module、wait-sendout module 、fingerprint module and personal information modules respectively. In the front-end interface to achieve Angular JS algorithm flow, the focus to take advantage of its two-way data binding interaction needs to achieve higher page complexity; Directive implements the use of a custom instruction create a targeted tags and attributes to extend HTML5 comes tag,so the browser can recognize the new grammar check system to complete the delivery of the specific needs; At the same time, according to needs of foreground and communication,we take advantage of Angular JS framework to provide a built-in service to achieve a reading of the background data.Finally, we introduce the configure environment to the sending visa system, and show the effect of front-end interface and associated key code for each module and other important work to verify the effect of the present framework. And through the testing and post on-line operation,sending visa system can be very good to complete the visa order dynamic management and maintenance, and to work closely with other business sectors, which made the visa management s more convenient, fast, accurate, and improve the couriers of productivity and company transfer visas orders.The innovation of this paper are as follows:1) Accomplishment of the front-end interface design and implementation of sending visa system which resolves the problem of slow order management and error-prone challenges, and provides a viable option for the travel company in order management.2) In practical work, in order to improve the stability and efficiency of the system, we presented the program for Angular JS $digest cycle and ng-repeat performance in terms of optimization.
