Sometimes you want to build a link URL which contains both server side and client side information. For instance, in your asp code you want to build this link:
<a href='DeleteRecord.asp?RecordID=&UserID=&UserPassword=
'>Delete this record</a>
"UserID" value and "UserPassword" values are user authentication information the user enters at client side before s/he clicks this link. While you can retrieve RecordID from a database by server-side, you have no way get user authentication information here. Here's one way to solve this problem:
First, the user authentication form:
<form name='formAuth' id='formAuth'>
<input type=text id='textUserID'>
<input type=password id='textUserPassword'>
</form>
Then, the JavaScript function:
<script language=javascript>
function DeleteRecord(parRecordID)
{
window.location.href ="DeleteRecord.asp?RecordID=
"+parRecordID
+ "&UserID=" +
document.formAuth.textUserID.value
+ "&UserPassword=" + document.formAuth.textUserPassword.value
}
</script>
When you build the link again, suppose you have retrieved "RecordID" value from the database and saved it to a variable "valRecordID".
<a href='javascript:DeleteRecord(<%=valRecordID%>)
'>Delete this record</a>
