VBScript traverses form elements to simplify data operation code

(ASP) traversing form elements to simplify data operation code

Function and description:
Most data operations are inseparable from forms. During update, a bunch of request. * and data fields must be listed.
Using traversal form elements saves a bunch of unnecessary things.

Msdn explains selectsinglenode.

1. Two methods to traverse form elements:

Linenum
1. Form
3. 1. Traverse form elements
4. Dim x' lists all elements in the form
5. For x = 1 to request. Form. Count
6. Response. Write Request. Form. Key (x )&"---"
7. Response. Write Request. Form (x) & "<br/>"
8. Next
9. // Request. Form. Key (x) is the element name.
10. // Request. Form (x) is the element value.
12. 2. Traverse form elements-method 2
13. Dim ELEM
14. For each ELEM in request. Form
15. Response. Write ELEM
16. Response. Write Request (ELEM)
17. Response. Write "<br/>"
18. Next
19. // ELEM is the element name.
20. // Request. Form (ELEM) is the element value.

2. An example of operating XML data

Linenum
1. <%
2. Dim hidchkvalue
3. Hidchkvalue = request ("hidchkvalue ")
4. Select case hidchkvalue
5. Case "siteconfig"
6. Set objxml = server. Createobject ("Microsoft. xmldom ")
7. Objxml. Load (server. mappath ("include/system/config. xml "))
8. For each ELEM in request. Form
9. If instr (ELEM, "Site") <> 0 then
10. Temp = request (ELEM)
11. If temp = "" Then temp = ELEM & "undefined"
12. Objxml. selectsinglenode ("//" & ELEM). Text = temp
13. End if
14. Next
15. Objxml. Save server. mappath ("include/system/config. xml ")
16. Set objxml = nothing
17. Response. Write pmtreturn
18. End select
19. %>
