ext中store.load跟store.reload的区别示例介绍

reload : function(options){
this.load(Ext.applyIf(options||{}, this.lastOptions));
},

load : function(options) {
options = Ext.apply({}, options);
this.storeOptions(options);
if(this.sortInfo && this.remoteSort){
var pn = this.paramNames;
options.params = Ext.apply({}, options.params);
options.params[pn.sort] = this.sortInfo.field;
options.params[pn.dir] = this.sortInfo.direction;
}
try {
return this.execute('read', null, options); // <-- null represents rs. No rs for load actions.
} catch(e) {
this.handleException(e);
return false;
}
},
