ASP to implement a less annoying automatic pop-up window

Pop-up windows Auto Popup is a nasty thing, why do we use it to show our questionnaires?

Using pop-up windows to display questionnaires is considered to be the easiest and quickest way to gather access to user information. When the first questionnaire was produced, we politely asked people if they would like to fill out the form, but the result was disappointing. So we decided to put the questionnaire on our homepage, and when people visit it automatically pops up, the effect is surprisingly good.

Here is the secret of our success:
1: Automatic pop-up window can only be displayed once, regardless of whether the user filled out the questionnaire.
2: Automatic pop-up window does not affect the display speed of the home page.
3: Automatic pop-up window after the user fills out the questionnaire, automatically disappear.
4: The Automatic pop-up window appears on the top left of the screen.
5: Automatic pop-up windows do not add ads, because our goal is to get the user's investigation report.

We used a small cookie to determine whether to pop the window. We define a cookie that can be used more than once and to judge multiple pop-up windows. We named this cookie "s", which contains the IDs of all the windows that have been ejected.
Now, when the user accesses the home page, we determine whether the requested ID is already contained in the cookie. If the cookie does not exist, we pop the window and write the cookie to prevent the window from popping again.
In the example below, we write cookies on the server side, which we can do with JavaScript, and we choose the server side because it's simpler.
At the very beginning of our homepage, we execute the ASP code. This code is to be placed before the HTML output because we need to edit the header.
<%
Dim Bsurvey ' Whether to display questionnaires
The ID of the const bid= "1" questionnaire

Bsurvey=false
' Check whether the questionnaire has been shown
If InStr (Request.Cookies ("s"), ":" & BID & ":") =0 Then
' Questionnaire not shown, update cookie

' Set cookie expiration time of 60 days
Response.Cookies ("S"). Expires = DATEADD ("D", 60,now ())
' Set path
Response.Cookies ("s"). Path = "/"
' Write Cookie
Response.Cookies ("s") = Request.Cookies ("s") & ":" & BID & ":"


Bsurvey=true
End If
%>

We give each questionnaire an ID, and if you have more than one pop-up window, you can easily have the planned output.

We add an ASP script at the end of the page to determine whether the pop-up window, this script side at the end of the page, does not affect the download speed of the home page. This script is very simple, it uses window.open () to open a new window.

<% if Bsurvey then%>
<SCRIPT>
window.open ("/survey/displaysurvey.asp?q=" & BID, "survey", "Width=350,height=400,top=0,left=0,scrollbars=yes" )
</SCRIPT>
<% End If%>
