GwtQuery（gQuery）是否像jQuery这样的跨浏览器库？

Question

Does GwtQuery offer the same browser compatibility as jQuery? If not, what browsers has it been tested with?

Answer 1

• gQuery(GwtQuery) supports Browser compatibility as jQuery.
• Each browser gets separately compiled JS

gQuery is an entire rewrite of GWT in jQuery.

GQuery and jQuery are built around selectors.

Both support CSS standard selectors plus extra selectors (:text :password :hidden etc).

jQuery uses the sizzle engine. A javascript engine which works with any browser and has optimizations per browser.

GQuery has optimized engines written in java.

The more appropriate engine is selected in compile time.

GQuery uses a modified sizzle version for IE6/7

GQuery adds compile-time optimizations when using compiled selectors.

Compiled Selectors

• Use them with immutable selectors and when selector performance is a goal in your application.

Selectors Performance

• GQuery in compiled mode produces the faster javascript code to select DOM elements.

• GQuery dynamic selectors are, in most cases, faster or equal than any other library.

Events

• GQuery provides methods for assigning event in a cross-browser way.
• GQuery event system is compatible with Gwt.
• issues: – When Gwt detaches a widget, events added via GQuery are lost.
