Form set
Note that this ASP instance tutorial is about form code. To save trouble, I cannot! You can test the instance execution result on your own!
Simple Application of a Form set
This example shows how to retrieve a value from a Form in the Form set. This form uses the POST method, which means that the sent information is invisible to users and there is no limit on the amount of sent information (a large amount of information can be sent ).
The sample code is as follows:
Reference content is as follows: <Html>
<Body>
<Form action = "/example/aspe/demo_aspe_simpleform1.asp" method = "post">
First name:
<Input type = "text" name = "fname" value = "Donald"/>
<Br/>
Last name:
<Input type = "text" name = "lname" value = "Duck"/>
<Br/>
<Input type = "submit" value = "Submit"/>
</Form>
<%
Response. Write (Request. Form)
%>
</Body>
</Html> |
How to use information from Forms
This example shows how to use the information retrieved from the form. We use the Form set. The form uses the POST method.
The sample code is as follows:
Reference content is as follows: <Html>
<Body>
<Form action = "/example/aspe/demo_aspe_simpleform.asp" method = "post">
Your name: <input type = "text" name = "fname" size = "20"/>
<Input type = "submit" value = "submit"/>
</Form>
<%
Dim fname
Fname = Request. Form ("fname ")
If fname <> "" Then
Response. Write ("Hello! "& Fname &"! <Br/> ")
Response. Write ("How is today? ")
End If
%>
</Body>
</Html> |
More information from the form
This example shows what information the Form set contains if several input fields use the same name. It will show how to separate these identical names. It also shows how to use the count keyword to count the "name" attribute. This form uses the POST method.
The sample code is as follows:
Reference content is as follows: <Html>
<Body>
<Form action = "/example/aspe/demo_aspe_form2.asp" method = "post">
First name:
<Input type = "text" name = "name" value = "Donald"/>
<Br/>
Last name:
<Input type = "text" name = "name" value = "Duck"/>
<Br/>
<Input type = "submit" value = "Submit"/>
</Form>
<Hr/>
<P> information from the preceding form: </p>
<%
If Request. Form ("name") <> "Then
Response. Write ("<p> ")
Response. Write ("name =" & Request. Form ("name "))
Response. Write ("</p> <p> ")
Response. Write ("Number of name attributes :")
Response. Write (Request. Form ("name"). Count)
Response. Write ("</p> <p> ")
Response. Write ("First name =" & Request. Form ("name") (1 ))
Response. Write ("</p> <p> ")
Response. Write ("Last name =" & Request. Form ("name") (2 ))
Response. Write ("</p> ")
End if
%>
</Body>
</Html> |
Form with single-choice button
This example shows how to use the Form set to interact with users through the single-choice button. This form uses the POST method.
The sample code is as follows:
Reference content is as follows: <Html>
<%
Dim cars
Cars = Request. Form ("cars ")
%>
<Body>
<Form action = "/example/aspe/demo_aspe_radiob.asp" method = "post">
<P> select your favorite car: </p>
<Input type = "radio" name = "cars"
<% If cars = "Volvo" then Response. Write ("checked") %>
Value = "Volvo"> Volvo </input>
<Br/>
<Input type = "radio" name = "cars"
<% If cars = "Saab" then Response. Write ("checked") %>
Value = "Saab"> Saab </input>
<Br/>
<Input type = "radio" name = "cars"
<% If cars = "BMW" then Response. Write ("checked") %>
Value = "BMW"> BMW </input>
<Br/>
<Input type = "submit" value = "submit"/>
</Form>
<%
If cars <> "" then
Response. Write ("<p> your favorite car is" & cars & "</p> ")
End if
%>
</Body>
</Html> |
Form with check button
This example shows how to use the Form set to interact with users through the check button. This form uses the POST method.
The sample code is as follows:
Reference content is as follows: <Html>
<Body>
<%
Fruits = Request. Form ("fruits ")
%>
<Form action = "/example/aspe/demo_aspe_checkboxes.asp" method = "post">
<P> what fruits do you like: </p>
<Input type = "checkbox" name = "fruits" value = "Apples"
<% If instr (fruits, "Apple") then Response. Write ("checked") %>
Apple
<Br>
<Input type = "checkbox" name = "fruits" value = "Oranges"
<% If instr (fruits, "Oranges") then Response. Write ("checked") %>
Orange
<Br>
<Input type = "checkbox" name = "fruits" value = "Bananas"
<% If instr (fruits, "Banana") then Response. Write ("checked") %>
Banana
<Br>
<Input type = "submit" value = "submit">
</Form>
<%
If fruits <> "" then %>
<P> you like: <% Response. Write (fruits) %> </p>
<% End if
%>
</Body>
</Html> |
