perseverereststore.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["dojox.data.PersevereRestStore"]){ //_hasResource checks added by build. Do not use _hasResource directly in your code.
dojo._hasResource["dojox.data.PersevereRestStore"] = true;

dojo.require("dojox.data.JsonRestStore");
dojo.require("dojox.json.ref"); // TODO: Make it work without this dependency

// PersevereRestStore is an extension of JsonRestStore to handle Persevere's special features


dojo.declare("dojox.data.PersevereRestStore",
