使用改代码只需要13行代码 原始需要25-30行代码搞定 ，示例：

	saveRecord: function() {
	    $postForm({
	        formPanel:this.formPanel,
	        scope:this,
	        url: __ctxPath + "/basedata/saveStudentDepartment.action",
	        params:{},
	        callback: function(d, f) {
				var e = Ext.getCmp("StudentDepartmentGrid");
				if (e != null) {
					e.getStore().reload();
				}
				b.close();
            }
	    });
