extjs 传值问题？

Question

我在后台 为什么得不到cmd的值呢？

[code="java"] this.fp.form.submit({

waitMsg: '正在保存。。。',

url: this.baseUrl + "?cmd=Save",

method: 'POST' ,

success: function(){

this.closeWin();

this.store.reload();

},

failure:function(form,action) {

Ext.MessageBox.alert("提示!","信息操作失败!");

},

scope: this

}); [/code]
