Description

Realize the Web performance analysis system and the method for browser-cross in the Internet application system

Technical field

The present invention relates to the Internet application system field, be particularly related to enterprise Web application system field and the Internet Web application and mobile Internet WAP and use and the Widget applied technical field, specifically be meant the Web performance analysis system and the method that realize browser-cross in a kind of Internet application system.

Background technology

Along with the development of modern social science technology, Internet technology has been deep into different social sectors.In enterprise uses, the computer software of large enterprise is the continuous progress of enterprise application system, C/S (client/server) pattern by the past changes present B/S (browser/server) pattern into, and traditional enterprise application system has become enterprise Web application system; In the internet, applications, the fast development of Internet technology is that the web of core technology uses main flow, particularly RIA technology and the Widget technology become Internet technology already and more brought revolutionary development with HTML, CSS, Javascript; In the mobile Internet, the arriving in 3G epoch makes WAP and Widget technology also enter develop rapidly period.

The development of Internet technology has driven the development of browser, and the browser on desktop computer and the mobile device emerges in an endless stream.Numerous browsers such as Internet Explorer, the Firefox on the desktop computer, Chrome, Safari, Opera have launched the browser Great War, and the Opear Mini on the mobile device, Windows Mobile IE, Gorilla, UCWEB also are the redactions that occurs frequently.HTML, CSS, Javascript technology are the bases of Internet technology, a kind of especially requisite script of Javascript language.Though each browser manufacturer is all in the operational efficiency that improves Javascript as possible, the consumer-user of Internet technology relatively, performance issue remains a significant problem of internet, applications.

At present only at 8.0 versions of the Firefox of desktop operating system browser and IE browser performance analysis tool is arranged, the API that their performance analysis tool all is based on browser to be provided develops.Yet other numerous browsers but do not have performance analysis tool.

Present Javascript debugging acid mainly can be debugged Javascript under IE and firefox, because IE and Firefox provide the debugging interface of javascript respectively.With Firefox is example, and Fig. 1 has illustrated the relation of the performance analysis tool Firebug on the Firefox, Page Speed and firefox.Firefox provides Javascript debugging interface: jsdIDebuggerService, can inject the hook of some debugging to it, and realize performance evaluation, the debugging interface that it provides mainly contains functionHook, scriptHook, topLevelHook etc.The user is registered to it among the jsdIDebuggerService as long as realize these interfaces, can do the ruuning situation performance evaluation of Javascript in Firefox.Firefox provides Http the interface nsIStreamListener of request equally, utilizes its onDataAvailable method can do the performance evaluation of Network Transmission.

Yet several drawbacks of this method for analyzing performance comprise: can not browser-cross, because the interface difference that browser provides, can not be general based on the performance analysis tool that browser develops, present performance analysis tool all is to use on IE, Firefox, and on browsers such as chrome, safari, opera and Opear Mini, Windows MobileIE, Gorilla, UCWEB on the mobile device all can not do performance evaluation; Need plug-in unit is installed, this type of performance analysis tool all need be installed plug-in unit on browser; The upgrading of browser version can cause performance analysis tool not use; Be difficult to accomplish combine analysis or the like with CPU, internal memory etc.
