The invention provides a method for achieving design of a 
client program. The method comprises the following steps that a, a webpage is designed in a visual or coding mode by a user through a design program; b, when the webpage is issued through the design program, content of the webpage is stored to a file in a 
compiled language in a word string mode; c, according to the design program, the file in the step b is compiled through an internally-arranged 
compiler, an 
executable program 
package is generated, and therefore issuance is accomplished; d, when the 
executable program 
package is executed through an inlet program, a 
specific function in the program 
package is called, and the content of the webpage in the step b is returned; e, the obtained content of the webpage is shown by the 
executable program package through an internally-arranged browser kernel, so that interaction between the executable program package and the user is achieved. According to the method, the advantages of a C / S frame and the advantages of a B / S frame in the program design aspect are integrated thoroughly, so that the safety, high efficiency and the communication capacity with a 
client hardware interface of a C / S frame 
system are achieved and an interactive interface with good user experience is provided in rich webpage content showing 
modes.
