record-min.js

一个struts和extjs得源码

Ext.data.Record=function(a,b){this.id=(b||b===0)?b:++Ext.data.Record.AUTO_ID;this.data=a};Ext.data.Record.create=function(e){var c=Ext.extend(Ext.data.Record,{});var d=c.prototype;d.fields=new Ext.util.MixedCollection(false,function(f){return f.name});for(var b=0,a=e.length;b<a;b++){d.fields.add(new Ext.data.Field(e[b]))}c.getField=function(f){return d.fields.get(f)};return c};Ext.data.Record.AUTO_ID=1000;Ext.data.Record.EDIT="edit";Ext.data.Record.REJECT="reject";Ext.data.Record.COMMIT="commit";Ext.data.Record.prototype={dirty:false,editing:false,error:null,modified:null,join:function(a){this.store=a},set:function(a,b){if(String(this.data[a])==String(b)){return}this.dirty=true;if(!this.modified){this.modified={}}if(typeof this.modified[a]=="undefined"){this.modified[a]=this.data[a]}this.data[a]=b;if(!this.editing&&this.store){this.store.afterEdit(this)}},get:function(a){return this.data[a]},beginEdit:function(){this.editing=true;this.modified={}},cancelEdit:function(){this.editing=false;delete this.modified},endEdit:function(){this.editing=false;if(this.dirty&&this.store){this.store.afterEdit(this)}},reject:function(b){var a=this.modified;for(var c in a){if(typeof a[c]!="function"){this.data[c]=a[c]}}this.dirty=false;delete this.modified;this.editing=false;if(this.store&&b!==true){this.store.afterReject(this)}},commit:function(a){this.dirty=false;delete this.modified;this.editing=false;if(this.store&&a!==true){this.store.afterCommit(this)}},getChanges:function(){var a=this.modified,b={};for(var c in a){if(a.hasOwnProperty(c)){b[c]=this.data[c]}}return b},hasError:function(){return this.error!=null},clearError:function(){this.error=null},copy:function(a){return new this.constructor(Ext.apply({},this.data),a||this.id)},isModified:function(a){return !!(this.modified&&this.modified.hasOwnProperty(a))}};
