Как получить return true или false из javascript в код позади
функция confirm_meth() {
var confirmed = confirm('там есть еще несколько предметов с таким же номером скольжения. Вы хотите продолжить');
если (подтверждено == true) {
вернуть true;
}
еще {
возвращать false;
}
}
Элемента управления scriptmanager.RegisterStartupScript(страницы, метод gettype(), "confirm_meth", "confirm_meth()", правда);
Отправить код кнопки следующим образом
string url = строка.Пустой;
bool isAgri = true;
int count = 0; //добавлено
foreach (строка GridViewRow в grdRpt.Rows)
{
Флажок ЧК = (флажок)grdRpt.Строк[подряд.Параметр rowindex].FindControl("chkselecdata");
если (ЧК.Проверено == верно)
{
считать++;
int key = конвертировать.ToInt32(grdRpt.DataKeys[строка.Параметр rowindex].Значение);
if (row.Cells[4].Text == "Agri Input")
{
isAgri = истина;
url = ConfigurationManager.AppSettings["SAPAgriInputPostingUrl"].Метод toString();
}
перерыв;

In the runmode when i click the submit i get alert message as "There are some more items with same slip number is there. Do you want to proceed?"
Ok Cancel.
i click ok
in the below line i cannot get the System.Web.UI.ScriptManager.RegisterClientScriptBlock(Page, typeof(System.Web.UI.Page), "Script", "confirm_meth();", true);
retrun value
what is the mistake in my above code?
What I have tried:
function confirm_meth() {
var confirmed = confirm('There are some more items with same slip number is there. Do you want to proceed');
if (confirmed == true) {
return true;
}
else {
return false;
}
}
ScriptManager.RegisterStartupScript(Page, GetType(), "confirm_meth", "confirm_meth()", true);
