Re: Event with javascript in .NET

You can't (at least not as far as I know). That OnLoad event is strictly server-side.

You can put an onload event on the BODY tag which would have the effect you want.

In IE the following are available...

document.body.clientWidth
document.body.clientHeight
document.body.offsetWidth;
document.body.offsetHeight;
window.screen.width
window.screen.height

have a string value, need its related integer value

Re: have a string value, need its related integer value

<%
Do While Not RS.EOF
Response.Write ""
Response.Write RS("Skill")
RS.MoveNext
Loop
%>"><% Response.Write (Session("strSkill"))%>

The option i wish to be selected is that value which is obtained from a previous form. this value is StrSkill. it is a string value. however, when adding the record to a database(in the next form), i need SkillID, which is an integer value. i am trying to obtain this by means of the SQL statement but it is not working. what is the problem, or is there an alternative soln? (note: the table is Skills : Skill(text), SkillID(int))
thank you!

Use CInt() in VBS to convert it.

my explanation was very vague-im sorry! in the next form ,i wish to add a record to a table, which requires the skillID RELATING to strSkill. this can be derived via a SQL statement (which reads the value from the database)

Looking again at your original message, it seems I missed the point completely, doesn't it?

I think this is the fix you're looking for:

<select NAME="Skills">
<%
Do While Not RS.EOF
Response.Write "<option VALUE='" & RS("SkillID") & "'"
If RS("Skill") = Session("strSkill") Then
    Response.Write " selected"
End If
Response.Write ">" & RS("Skill") & </option>
RS.MoveNext
Loop
%>
</select>

What you were trying to do would have produced:

<select NAME="Skills">
<option value="1">Skill 1
<option value="2">Skill 2
<option value="3">Skill 3
<option value="4">Skill 4
<option value="5">Skill 5
<option selected="4">Skill 4</option>

(or something like that) But what you really want is

<select NAME="Skills">
<option value="1">Skill 1</option>
<option value="2">Skill 2</option>
<option value="3">Skill 3</option>
<option value="4" selected>Skill 4</option>
<option value="5">Skill 5</option>
</select>

Browser DOM references

Re: Browser DOM references

4-Sep-02 0:28

Where is a good cross reference for all major broswers...?

IE, NS and Opera...???

I came up with a stellar idea for that web dev contest, but I will require a cross reference to properly implement it...

Any sites...?

Thanx.

p.s-Old browser which supported DHTML right up to cutting edge would be great...Mainly IE and Nestacape are my concerns.

I've always liked the book "The JavaScript Bible." I have the first edition, which doesn't cover Opera, but the newer edition(s) may - I just haven't seen it to verify.

Also, developer.netscape.com is a good start too, but it won't cover Opera.

Re: Ignore my last message read me instead

Sweet....I figured out a most interesting way of implementing the above, but one thing still gets me...

In NS you have the elements collection for iterating all elements in the document and IE offers the same using the all collection. However getElemenyById was introduced by the W3C to eliminate cross browser incompatibilities(I assume anyways). Does this mean both major browser players will eventually eliminate these collections of theirs in favour of the W3C standard getElementById() ...?

Just curious

getElemenyById isn't supported in NS 4.7 or below. So if you have that to worry about, you're out of luck.

Retrieving the next element...???

online billing for students....

3-Sep-02 23:40

if I have the following..

<TD></TD><TD id="Something">Something</TD><TD><IMG/></TD>

How could I get the id of the IMG tag from inside an onMouseOver of the id="something" TD tag...?

IE supports a property called owningElement which I think does something like this...?

Is there any way I can retreive the IMG id ( I want to change the src property ) without supplying the IMG tag an ID also...??

i'm thinking if I could somehow use the all collection:

onMouseOver:

var i = document.all(this.curIndex)+2;

// change image now
document.all(i).src = "diff.gif"

does something like curIndex exist...?

I would like this to be cross browser...so NS elements collection and IE all collection won't work...

Thanx! Smile | :)

deriving an integer value

Re: deriving an integer value

3-Sep-02 6:08

my tables are:
skills: skill(str), skillID(autonumber))
subcategory: subcategory(str), subcategoryid(autonumber), skillID(int)

i am obtaining the value for skill in the string type via a text box(strSkill). however, i need to save this value to the subcategory table as its ID number (ie as an interger value). i am trying to use a SQL statement to derive its related ID, but am failing to do so. where is the problem?

dim sql
sql = "SELECT DISTINCT SkillID FROM Skills WHERE (((Skills.Skill)='" & replace(strSkill,"'","''") & "'))"
Set RS = objConn.Execute(SQL)

If Not bolAlreadyExists Then

RS.AddNew
'adding the new subskill to the table

RS("SubCategory") = Request.Form("SubCategory")
RS("SkillID") = Request.Form("Skills")
'closing the recordset and connection object
RS.Update
RS.Close

thank you! Smile | :)

Hmmm...ok. Here is a note; you don't need to place DISTINCT in front of SkillID if it is defined as an autonumber and the only field you are selecting (those will always be distinct). If you already have your variable skill defined you should be able to do something like this to get the SkillID:

dim conn
dim rs
set conn = Server.CreateObject("ADODB.Connection")
set rs = Server.CreateObject("ADODB.Recordset")

'if you haven't defined your skill do it here
dim skill, SkillId
skill = replace(Request.Form("skill"), "'", "''")
sql = "SELECT SkillID FROM skills WHERE skill = '" & skill & "'"
conn.ConnectionString = "[.......]"
conn.Open
rs.ActiveConnection = conn
rs.Open(sql)
If Not rs.EOF Then
   SkillId = rs("SkillID")
End If
If SkillId = "" Then
   'Add New Record Here
End If
rs.Close
Set rs = Nothing
conn.Close
Set conn = Nothing

passing values when redirecting

mcm3-Sep-02 5:06

Re: passing values when redirecting

3-Sep-02 5:06

is it possible to pass values between forms when using the Response.Redirect Method?

If (Request("City") = 22) Then
Dim strSkill
strSkill = Request.Form("Skills")
Response.Redirect("add3.asp")
Else.....

in the above code section, i wish to pass the value contained in the "Skills" combo box (located on prev page), but when redirected to the add2.asp form , the value is lost. is there any way to rectify this using VBSCript?
thank you? Smile | :)
