The reason why the network booking to do some research actually stems from a recent set of test questions, the following analysis is a lack of a large number of user research, the right to improve personal ability and do some exercises.
At present, the booking website is overwhelming, in addition to the major airlines of the portal booking, a variety of small professional booking sites countless, but involved in the process of money transactions, users tend to be high visibility, high reliabili

First, User role (ADA)
If you want to make a comprehensive list of user types for a site, you need to do a lot of user research. But after a brief analysis, the ADA is a typical example of a mainstream user, which can be found after the ADA is refined.
It can be seen that the ADA use QQ travel

his contributions to open source projects have been resented by some people. This dilemma exposes a delicate problem, and companies that rely on open source technology for business success need to try to regulate the open source community without real control. When companies start to regulate open-source community behavior, they will be very cautious, because it could stifle innovation or cause community members to question the motives of the company's supervisors. If the situation starts to be

Memory Model
During the process of creating a class using the prototype method, the prototype has four different states in the memory. We still create the Person class example above to analyze the prototype memory model. The Code is as follows:
// First state function Person () {}; // Second State Person. prototype. name = "Leon"; Person. prototype. age = 22; Person. prototype. say = fucntion () {alert (this. name + "," + this. age) ;}// the third State. After an object is created, a _ proto _

In the net2.0 environment, each method in the Web service generates an Asynchronous Method and an end event in the proxy class generated after adding a reference to the client. We can use this Asynchronous Method and event to easily call web service in different steps.
Simple Example
Assume that a data query method is defined in Web Service:
