Most of the time, when you don't know the number of forms you need, you need to be able to control the number of forms. The following two effects were collected:

　　Effect 1:

<ptml><body><form name=" Form1 "><table id=" tb1 border=0> <tr><td><a "#" > Add Attachment href= ></table><input type= "hidden" name= "fjcnt" value= "1"/></form></body></ptml>< Script language= "JavaScript" > Function addfj () {var oTb = document.getElementById ("tb1"); var oTr = otb.insertrow (0); var name = "Thefilename" +document.form1.fjcnt.value; Document.form1.fjcnt.value=parseint (Document.form1.fjCnt.value) +1; Otr.insertcell (0). InnerHTML = "<input id= ' file ' name= '" +name+ "' Type=file style= ' width:400px; ' > <input Type=button > "return false; } function delfj (obj) {Obj.parentElement.parentElement.removeNode (true); return false; }</script>

　　Effect 2:

<ptml><pead><style type= "Text/css" ></style><script LANGUage= "VBScript" >function AddFile () Dim strstr= "<table>" If not IsNumeric (Window.form1.filenum.value) Then Window.form1.filenum.value =1for I=1 to window.form1.filenum.valuestr=str& "<tr><td valign= ' middle ' >　　File "&i&": </td><td><input type= ' file ' name= ' file ' &i& ' class= ' tx1 ' value size= ' ' > Save As <input type= ' text ' name= ' file ' &i& ' ' size= ' class= ' tx2 ' ></td></tr> ' Nextwindow.uptd.innerHTML =str& "</table>" End Function</script><script language= "JavaScript" ></script><title></title><meta http-equiv= "Content-type" CONTENT= "text/html; charset=gb2312 "></pead><body bgcolor=" #ffffff "class=" p9 "><form method=" Post "Name=" Form1 "ACTION = "savetofile.asp" enctype= "Multipart/form-data" > <table border= "0" align="Center" cellpadding= "0" cellspacing= "0" > <TR> <td><div align= "center" ><font color= "#0000 FF "size=" 5 > Save to File </FONT></DIV></TD> </TR> <TR> <td><table width= "75 0 "border=" 1 "align=" center "cellpadding=" 0 "cellspacing=" 0 "bordercolor=" #111111 "style=" Border-collapse:collapse " > <TR> <td height= "colspan=" 2 "> Upload <input name=" FileNum "class=" TX 2 "value=" 1 "size=" 4 "> Files <input type=" button "name=" button "class=" BT "value=" set "&G T </TD> </TR> <TR> <TD> <div id= "UPTD" > </DIV></TD> </TR> <TR> <td height= "colspan=" 2 "align=" middle "> <i Nput type= "button" name= "button" class= "BT" value= "See how many Boxes" > <input type= "Submit" name= "button" class= "BT" Value= " Upload "> 　　 <input type= "Reset" name= "button" class= "BT" value= "reset" > </TD> < /tr> </TABLE></TD> </TR> </TABLE></FORM></BODY></HTML>

In ASP, dynamic forms can be submitted in the same way as normal forms. An easy way to do this is to set the name of a fixed form, and when multiple forms are submitted, the form data is automatically separated by "," and then split with split and then recycled to submit separately. As follows:

<% @LANGUAGE = "VBSCRIPT" codepage= "936"%>
<script language= "JavaScript" >
function Addtxtproductnamebox ()
{
var oTb = document.getElementById ("Tableproductname");
var oTr = otb.insertrow (0);
Otr.insertcell (0). InnerHTML = "<input name= ' txtproductname ' type= ' text ' ><input Type=button >"
return false;
}
function Deltxtproductnamebox (obj)
{
Obj.parentElement.parentElement.removeNode (TRUE);
return false;
}
</script>
<% Dim Rs3,sql3,productnamearray
If productname<> "" Then
Set Rs3=server. CreateObject ("ADODB.") RecordSet ")
Sql3= "SELECT * from Amdiproduct"
Rs3.open sql3,conn,3,2
Productnamearray=split (ProductName, ",")
For i = 0 To UBound (productnamearray)
Rs3.addnew
RS3 ("CompanyID") =companyid
RS3 ("ProductName") =productnamearray (i)
Rs3.update
Next
Rs3.close
Set rs3=nothing
End If
%>
<form name= "Form1" method= "Post" action= "" >
Products name £ º <a href= "#" > Add product Name </a>
<table id= "Tableproductname" border=0>
<tr><td> </td></tr>
</table>
<input name= "Submit" type= "submit" id= "Submit" value= "= = Submit"/>
</form>
