我有表格形式来添加订单的订单详细信息,
表格形式具有Popup LOV
此自定义属性:
onchange="javascript:do_cascade(this);"
这是最后一个函数的代码
function do_cascade(pThis)
{
var row_id=pThis.id.substr(4);
apex.server.process("cascade_order_values", { x02: $(pThis).val()},
{type:"GET", dataType:"json", success:function(json)
{
var cond=0;
// this var as flag changes to 1 when the new value found in tabular form.
var l_code=$(pThis).val();
// to catch selected value to compare it with tabular form values
for (i =row_id;i>0;i=i-1)
// this loop in order to check all tabluar form #f02_ column values
{
var id=('000'+i);//.slice(-4,0);
var curr_id='#f02_'+id;
var curr_code=$(curr_id).val();
if(curr_code==l_code)
{
$('#f05_'+id).val('got it');
$('#f05_'+id).focus();
// i=0; cond=1;
} else cond=0;
}
if (cond==0)
{
$('#f06_'+row_id).val(json.price);
$('#f04_'+row_id).val(json.pro_name);
}
else {
// I want to write something here to delete the new added row
}
}
}
);
}
最后一个函数很快做了什么:当Popup LOV的选定值发生变化时,函数调用应用程序查询并返回一些数据并将它们设置到表格表单字段中,这可以正确执行。这里是比这个函数过程的应用过程:
declare
price number;
pro_code nvarchar2(20):=null;
pro_name nvarchar2(50);
begin
pro_code:=apex_application.g_x02;
SELECT nvl(sell_price,0) into price from products where product_code=pro_code;
SELECT C.CAT_NAME || ' - ' || U.UNIT_NAME into pro_name
FROM PRODUCTS P , CATEGORIES C, UNITS U
WHERE P.CAT_ID=C.CAT_ID AND P.UNIT_ID=U.UNIT_ID AND P.PRODUCT_CODE=pro_code;
sys.htp.p('{"price":"'||price||'", "pro_name":"'||pro_name||'","code":"'||pro_code||'"}');
EXCEPTION
WHEN others
THEN
pro_name:='الرقم غير صحيح';
sys.htp.p('{"price":"'||0||'", "pro_name":"'||pro_name||'","code":"'||pro_code||'"}');
end;
问题是:
我想检查选定的产品代码是否存在时,that mean check tabular form row by row from current row to the first one
当所选值存在将焦点移动到item#f05_
并为其设置值时,然后删除已添加到表格表单的新行
请问我该怎么做。
请帮忙!..
