    $$(".BB").ADDEVENT('CHANGE',FUNCTION(E){
       VAR ORDER_ITEM_ID =  THIS.GET('ORDER_ITEM_ID');
       VAR PRODUCT_NAME= THIS.VALUE;
       NEW REQUEST.JSON({
            URL: "INDEX.PHP?APP=SALE&AMP;CTL=ADMIN_ORDERS&AMP;ACT=AJAX_DISCOUNT", 
            ONCOMPLETE: FUNCTION(PERSON, TEXT){
                IF(PERSON.STATUS==1){
                    ALERT(PERSON.MSG);
                }ELSE{
                    ALERT("提交失败");
                }
            }
        }).POST('ORDER_ITEM_ID='+ORDER_ITEM_ID+'&AMP;PRODUCT_NAME='+PRODUCT_NAME);
    });
    //后台方法
    FUNCTION AJAX_DISCOUNT(){
        $ID = $_POST['ORDER_ITEM_ID'];
        $PRODUCT_NAME =  $_POST['PRODUCT_NAME]
        $ORDER_ITEM_MDL = $THIS-&GT;APP-&GT;MODEL('ORDERS_ITEM');
        $ORDER_ITEM = $ORDER_ITEM_MDL-&GT;DUMP($ID);
        $ORDER_ITEM['PRODUCT_NAME']=$PRODUCT_NAME;
        $ORDER_ITEM_MDL-&GT;SAVE($ORDER_ITEM);
        $RESULT = ARRAY('STATUS'=&GT;1,'MSG'='信息修改成功']);
        ECHO JSON_ENCODE($RESULT);
