我在gridview中添加產品並檢查las記錄是否存在於列表中我有一個消息來更新已存在的記錄或刪除最後插入!以下是我的代碼,但它不起作用!誰能幫我?javascript與if語句在asp.net c後面的代碼中觸發按鈕c#
public void SaveToList()
{
try
{
OrdersDataContext contex = DataContextSingleton.Instance;
_order = new Order();
_order.quant = Int32.Parse(quant.Text);
_order.price = price.Text;
_order.totalprice = Decimal.Parse(totprice.Text);
_order.discoun_id = Int32.Parse(TextBox3.Text);
_order.prod_id = Int32.Parse(TextBox2.Text);
_order.regist_id = Int32.Parse(TextBox4.Text);
_readyToSave.Add(_order);
//contex.Orders.InsertOnSubmit(ord);
//contex.SubmitChanges();
if (_readyToSave.Count() != 0)
{
var selectO = (from o in _readyToSave
orderby o.prod_id
select new
{
val1 = o.prod_id
}).Last();
TextBox15.Text = selectO.val1.ToString();
var selectpr = from p in _readyToSave
where (p.prod_id == Int32.Parse(TextBox15.Text))
select p;
if (selectpr.Count() > 0)
{
btnAdd.Attributes.Add("onclick", "var agree=confirm('This product exist on you order! Do you want to update it???'); if (agree){document.getElementById('<%= btnUpdate%>').click();} else{document.getElementById('<%= btnDelNew %>').click();}");
//Response.Write("<script language='javascript'>alert('This product already have been added in list!!!')</script>");
}
}
ClearTheFields();
Sum();
}
catch
{
}
}
不知道爲什麼,但它停止工作,不調用按鈕.. btnAdd.Attributes.Add(「點擊」,「VAR同意=確認(「本品對你存在訂購!'); if(agree){document.getElementById(''+ btnUpdate.ClientID +'').click();} else {document.getElementById('「+ btnDelNew.ClientID +「').click();}」);誰能幫我???
請原諒這樣的問題:我已經限制了GridView控件的知識,但會在按鈕的屬性中使用文字「<%= btnUpdate.ClientId%>」自動分析爲「ctr001_btnUpdate」(例如)?我的直覺是,它只是簡單地發送到瀏覽器,就像字面意思,只是'<%= btnUpdate.ClientID%>' – freefaller
沒什麼,仍然不起作用! –
