Miscellaneous Methods Freedom of choice is what you got Freedom from choice is what you want —Devo, "Freedom of Choice" In the preceding chapters, we have examined many categories of jQuery methods. A few methods provided by the library have so far defied categorization, though. In this chapter, we will explore methods that can be used to abbreviate common JavaScript idioms. Setup Methods These functions are useful before the main code body begins. $.browser Contains information about the currently running browser. Parameters None. $.browser Return Value Boolean flags for each user agent possibility.
Miscellaneous Methods Description The $.browser property allows us to detect which web browser is accessing the page, as reported by the browser itself. It contains flags for each of the four most prevalent browser classes—Internet Explorer, Mozilla, Safari, and Opera. The browsers can be tested independently: $() .log('Safari: ' + $.browser.safari) .log('Opera: ' + $.browser.opera) .log('MSIE: ' + $.browser.msie) .log('Mozilla: ' + $.browser.mozilla); When executed on a Firefox browser, the results are: Safari: false Opera: false MSIE: false Mozilla: true This property is available immediately. It is therefore safe to use it to determine whether or not to call $(document).ready(). Because $.browser uses navigator.useragent to determine the platform, it is vulnerable to spoofing by the user. It is always best to avoid browser-specific code entirely where possible. In special cases where it needs to be written for different agents, the best alternative is to test for the presence of the JavaScript features you want to use. If this does not differentiate the clients well enough, the $.browser property can be used for further distinctions. $.noConflict() Relinquishes jQuery’s control of the $ variable. Parameters None. $.noConflict() Return Value The global jQuery object. This can be set to a variable to provide an alternative shortcut to $. [ 170 ]
