request.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["dojo.data.api.Request"]){ //_hasResource checks added by build. Do not use _hasResource directly in your code.
dojo._hasResource["dojo.data.api.Request"] = true;
dojo.provide("dojo.data.api.Request");

dojo.declare("dojo.data.api.Request", null, {
	//	summary:
	//		This class defines out the semantics of what a 'Request' object looks like
	//		when returned from a fetch() method.  In general, a request object is
	//		nothing more than the original keywordArgs from fetch with an abort function 
	//		attached to it to allow users to abort a particular request if they so choose. 
	//		No other functions are required on a general Request object return.  That does not
	//		inhibit other store implementations from adding extentions to it, of course.
	//
	//		This is an abstract API that data provider implementations conform to.  
	//		This file defines methods signatures and intentionally leaves all the
	//		methods unimplemented.
	//
	//		For more details on fetch, see dojo.data.api.Read.fetch().

	abort: function(){
		//	summary:
		//		This function is a hook point for stores to provide as a way for 
		//		a fetch to be halted mid-processing.
		//	description:
		//		This function is a hook point for stores to provide as a way for
