sniff.js

这是一个ajax的例子大家好好的看看就是一个鱼眼的效果

if(!dojo._hasResource["dijit._base.sniff"]){ //_hasResource checks added by build. Do not use _hasResource directly in your code.
dojo._hasResource["dijit._base.sniff"] = true;
dojo.provide("dijit._base.sniff");

// ported from dojo.html.applyBrowserClass (style.js)

//	summary:
//		Applies pre-set class names based on browser & version to the
//		top-level HTML node.  Simply doing a require on this module will
//		establish this CSS.  Modified version of Morris' CSS hack.
