10.ASP method to get form input data
: Get POST
A. Get: The client adds the data to the URL after the format is "? Field 1 = input data 1& field 2 = input data 2& ... ",
And then send it to the server.
For example: Action is www.abc.com, field name input data is Jack, field age data is 15, then use the Get method to
Http://www.abc.com?Name=jack&Age=15
Two. Post: The client uses HTTP information data to transfer to the server
In asp:
Get: Use "Enter data = request.querystring (field name)" To remove the data attached to the URL.
Post: Use the Enter data =request.forml (field name ")" to read the HTTP information data fields.
* Request.QueryString Example
such as: 〈a hery= "aspform.asp?" Name=jack&age=15 ">
Click here 〈/a〉〈p〉
Name:<%=request. QueryString ("Name")%)
Age:<%=request. Qeuerystring ("age")%)
* Get Example
aspturm.asp:
<form action= "asp1b.asp" method= "Get" >
Name: <input type=text name= "input1" value= "Your name" >
<p>
Features: <select name= "Input2" >
<option>cool!
<option>handsome
<option>warmhearted
</select>
<input type=submit value= "OK" >
</form>
The content of asp1b.asp
<% =request.querystring ("input1")%> Hi, your character is
<%= request.querystring ("Input2")%>
</body>11.request. From
Syntax: request. from (name) [(index) |. Count
Name: Field name
Index: When multiple values are entered in the same field, the pointer value index specifies the value to read the same field, ranging from 1 to
Request. From (name). Count
Count: By request. The From (name). Count knowable Name field enter several values, if no this name field, Count is 0
The following example:
<%
Fori=1 to Request.fron ("INPUT1"). Count
Response.Write Request. From ("Input1") (I) & "<br>"
Next
%>
If the INPUT1 has two values, it shows
* If the index is not used to specify which to read. Available
〈%
For each item request. From ("Input"))
Repomse.write Item & "<br>"
Next
%>
You can also use the for each x in Tewuest. From "repeatedly gets the input values for all fields.
<% for each x in request. Form%>
Request. From (<%=x%) =<%=request. Form
(x)%> <br>
<% Next%>
