Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Before the embodiment of the invention was set forth, the notion related to the embodiment of the invention was introduced:
JavaScript:Javascript is exactly a kind of being embedded in the webpage Html code, can be at a kind of programming language that is used to develop dynamic web page of browser client operation.
XmlHttpRequest: the customer end A cticeX object that can in JavaScript, create, use this object to initiate request to server, obtain data.
Ajax: be the abbreviation of Asynchronous JavaScript and XML (asynchronous JavaScript and XML), be meant a kind of webpage development technology that interaction network page is used of creating, wherein mainly used the xmlHttpRequest object.
XML: the abbreviation that is eXtensible Markup Language (extending mark language).XML is a kind of simple storage language, uses a series of simple mark data of description.Be exactly a kind of form of data of description structure in simple terms.
JSON: be that JavaScript Object Notation (the primary object of JavaScript) is a kind of data interchange format of lightweight.It is based on JavaScript Programming Language.JSON adopts the text formatting that is totally independent of language.JSON and XML are similar, also are a kind of forms of data of description structure, but more simple and convenient than XML when using in JavaScript.
Configuration diagram when Fig. 1 shows the embodiment of the invention based on the execution synch command of browsing neat long-range control method, it is existing that details are as follows:
The operator mentions an operational order on browsing device net page, generate an Ajax object among the JavaScript, initiates a synchronization request to server, can attach command parameter.The execution wait prompting that the back shows that on current web page an order is being carried out is sent in request.
After server receives command request, from request msg, extract command parameter, by communication channel order is sent to distant place equipment then.
Distant place equipment fill order is returned execution result and is given server.
Server is organized into an execution result object with execution result, wherein comprises command execution results, the time of implementation, carry out the miscue information of failure etc., and with the JSON form this object is turned back to client then.
Customer end A jax object detection is finished to server and returns, and at first closes the dialog box that display command is being carried out, and calls the data that a JavaScript call back function is resolved the JSON form that returns then, and the command execution results object is reduced.Run succeeded according to the execution result display command.Perhaps display command is carried out failure and miscue information.
