Howdy,
Just wondering how the following might be done:
I have a couple of different webpages that need to call a function to
clear the textbox onFocus of the textbox. I'm wanting to use one
function that I can call from a javascript include file (rather than
having multiple versions of the function all through the site).
So far i've tried the following:
function clearfield(poFo rm,poElement)
{
if (document.forms[poForm].poElement.valu e == "Type Search Here...")
document.forms[poForm].poElement.valu e = "";
}
where the passing page calls the function as:
clearfield('for mname','formele ment');
but just get errors.
Any help on this one would be most appreciative!!
Cheers

Not really. Didn't test it before posting, and as I see now,
there's a mistake: function clrTxt(oElem, oEvent) { if ( oElem && oElem.value && oElem.defaultVa lue && oEvent && oEvent.type ) {
should, of course, be replaced with:
function clrTxt(oElem, oEvent) {
if (
oElem
&& typeof oElem.value != "undefined"
&& oElem.defaultVa lue
&& oEvent
&& oEvent.type
) {

If I fill out the textfields properly with Name, Email etc in a row it
is fine. But if I fill out, for example, my Name, then tab twice, it
clears my entered value. How do I stop this?
All I want the script to do is that when the cell is blank or
whitespace, put the necessary text in the field, else, continue as
normal.

Hi everybody,
I have a lot of textboxes on my form and a "Clear" button. Is there a
way with a for loop or something to clear the textboxes, instead of
writing textboxName.clear?
Thanks a lot

I used to clear my page's control in Visual Studio 2003 using code like this:
Dim c As Control
For Each c In Page.Controls(1).Controls
If TypeOf c Is TextBox Then
CType(c, TextBox).Text = Nothing
End If
If TypeOf c Is DropDownList Then
CType(c, DropDownList).SelectedIndex = 0
End If
Next

foreach (TextBox tb in this.Controls)
tb.Dispose();
What this does is clears every other textbox on the form.
Suppose there are 10 textboxes... this will dispose the 1st one, then i
guess whatever list of textboxes it's maintaining gets shifted, so the
2nd is now the 1st in the list, so when it goes to the next one, it is
destroying the 3rd textbox, leaving the 2nd one safe...

Hey-o!
Can anyone tell me how to make this work?
Long story short, I would like to use text from TextBox1.Text as the functions I would like to call. Then I would like TextBox1.Text to show the result of the functions I just called.
(Pretend the line below is a textbox)
So therefore, TextBox1.Text would look like this = "Multiply(4,GrabNumFromAray(RandomNumGen(4)))"
