Appendix 1:
1) Simple
To add an authentication script to a button, you can
<% @ Page Language = "C #" %>
<SCRIPT language = "javascript">
Function getconfirm ()
{
If (confirm ("Do you want to delete record? ") = True)
Return true;
Else
Return false;
}
</SCRIPT>
<Script runat = "server">
Public void Page_Load (Object sender, EventArgs E ){
BtnSubmit. Attributes. Add ("onclick", "return getconfirm ();");
}
Void btnSubmit_Click (object sender, EventArgs e ){
Message. Text = "You entered your name as:" + txtName. Text;
}
</Script>
<Html>
<Head>
</Head>
<Body>
<Form runat = "server">
Name: <asp: Textbox id = "txtName" runat = "server"/>
<Asp: Button id = "btnSubmit" onclick = "btnSubmit_Click" runat = "server" Text = "Submit"> </asp: Button> <br/>
<Asp: Label id = "Message" runat = "server"/>
</Form>
</Body>
</Html>
Note the key points btnSubmit. attributes. add ("onclick", "return fffkkk ();"); this statement is equivalent to adding "onclick =" return fffkkk (); "to the static page tag.
2) more complex
Sometimes we need to add authentication in the delete column of the DataGrid.
First, create a DataGrid and add a delete column to her.
<Asp: DataGrid id = "DataGrid1" runat = "server">
<Columns>
<Asp: TemplateColumn>
<ItemTemplate>
<Asp: LinkButton id = "mongodel"
Runat = "server" Text = "Delete"
CommandName = "Delete" CausesValidation = "false">
</Asp: LinkButton>
</ItemTemplate>
</Asp: TemplateColumn>
</Columns>
</Asp: DataGrid>
Then write in the ItemDataBound event of the DataGrid as follows:
Private Sub DataGrid1_ItemDataBound
(ByVal sender As Object, ByVal e As DataGridItemEventArgs)
Handles DataGrid1.ItemDataBound
Dim l As LinkButton
If e. Item. ItemType = ListItemType. Item Or
E. Item. ItemType = ListItemType. AlternatingItem Then
L = CType (e. Item. Cells (0). FindControl ("mongodel"), LinkButton)
L. Attributes. Add ("onclick", "return getconfirm ();")
End If
End Sub
The Getconfirm () function is the same as the first one.
Function getconfirm ()
{
If (confirm ("Do you want to delete record? ") = True)
Return true;
Else
Return false;
}
In this way, you can.

Returns the interval between two dates.
Syntax
DateDiff (interval, date1, date2 [, firstdayofweek [, firstweekofyear])
The syntax of the DateDiff function includes the following parameters:
Parameter description
Interval is required. String expression indicates the time interval between date1 and date2. For values, see the "Settings" section.
Date1 and date2 are required. Date expression. Two dates used for calculation.
Firstdayofweek is optional. Specify the constant of the first day of the week. If not specified, the default value is Sunday. For values, see the "Settings" section.
Firstweekofyear is optional. Specifies the constant of the first week of a year. If this parameter is not specified, the default value is the week of April 1, January 1. For values, see the "Settings" section.
Set
The interval parameter can have the following values:
Set description
Yyyy
Q quarter
N months
Y number of days in a year
D
Number of days per week
Ww week
H hour
M minutes
S seconds
The firstdayofweek parameter can have the following values:
Constant Value description
VbUseSystem 0 is set using the regional language (NLS) API.
VbSunday 1 Sunday (default)
VbMonday 2 Monday
VbTuesday 3 Tuesday
VbWednesday 4
VbThursday 5 Thursday
VbFriday 6 Friday
VbSaturday 7 Saturday
The firstweekofyear parameter can have the following values:
Constant Value description
VbUseSystem 0 is set using the regional language (NLS) API.
VbFirstJan1 starts from the week of July 1, January 1 (default ).
VbFirstFourDays 2 starts from the first week of at least four days in the New Year.
VbFirstFullWeek 3 starts from the first complete week of the year.
Description
The DateDiff function is used to determine the number of specified time intervals between two dates. For example, you can use DateDiff to calculate the number of days with different dates, or the number of weeks between the day and the last day of the current year.
To calculate the number of days for date1 and date2, you can use "number of days in a year" ("y") or "day" ("d "). When interval is "the number of days of a week" ("w"), DateDiff returns the number of weeks between two dates. If date1 is Monday, DateDiff calculates the number of Monday before date2. This result contains date2, not date1. If interval is "Week" ("ww"), the DateDiff function returns the number of weeks between two dates in the calendar table. Function compute the number of Sundays between date1 and date2. If date2 is Sunday, DateDiff calculates date2, but date1 is not calculated even if date1 is Sunday.
If date1 is later than date2, The DateDiff function returns a negative number.
The firstdayofweek parameter affects the calculation of the "w" and "ww" separators.
If date1 or date2 is a date text, the specified year will become a fixed part of the date. However, if date1 or date2 is included in quotation marks ("") and the year is omitted, the current year will be inserted every time date1 or date2 expressions are calculated in the code. In this way, you can write program code for different years.
When interval is "year" ("yyyy"), although only one day is actually different from January 1, DateDiff returns 1, indicating that the year is different.
The following example uses the DateDiff function to display the number of days between today and the given date:
Function DiffADate (theDate)
DiffADate = "days from the current day:" & DateDiff ("d", Now, theDate)
End Function

When interval is "the number of days of a week" ("w"), DateDiff returns the number of weeks between two dates. If date1 is Monday, DateDiff calculates the number of Monday before date2. This result contains date2, not date1. If interval is "Week" ("ww"), the DateDiff function returns the number of weeks between two dates in the calendar table. Function compute the number of Sundays between date1 and date2. If date2 is Sunday, DateDiff calculates date2, but date1 is not calculated even if date1 is Sunday.
If date1 is later than date2, The DateDiff function returns a negative number.
