Using the onchange
command with a drop
down list |
|
|
|
|
|
Follow these instructions to
make your drop down list execute
when a selection is made instead
of using a submit button. |
|
|
You will place your drop down
list in a form and set the form
action to your
database results page. You use a
Onchange event that uses the
form name and is
added to the select tag. When
you select a choice from the
list, the selected
option will be submitted to a
form handler when a selection is
made
automatically.
Follow steps below:
1. Open a page that contains a
drop down list, that when a
option is selected
you want to submit to a results
page.
2. Select the drop down list,
from the Insert menu select the
Form menu, and
click Form, this will create a
form around your drop down list.
3. Right click the form, and
choose Form Properties
4. In Form Properties, click
Send to Other, click Options and
enter a page name
that will be used to show
results based on criteria, the
value from this drop
down list we be passed to that
page.
5. Enter a form name, like
"Form1", click OK to exit Form
Properties.
6. In Page View, place the
curser just in front of your
drop down menu, and
click HTML view tab.
7. Locate the tag for the drop
down menu, it will start with:
<Select>
8. Add the following text to the
Select tag, just after the name:
onchange=form1.submit()
It should look something like
the example below:
<select size="1"
name="Dropdown1" onchange=form1.submit()>
This will specify which form
name to use, choosing a
selection from the drop
down list will submit the
results to the form's action.
9. Save and Preview the page.
Your final code will look like
the example below:
<form method="POST" name="form1"
action="listresults.asp">
<p><select size="1"
name="Dropdown1" onchange=form1.submit()>
<option
value="Option1">Option1</option>
<option
value="Option2">Option2</option>
<option
value="Option3">Option3</option>
</select>
</form>
NOTE: To make this work, you
will need to create a database
results region that
includes criteria. You will
specify a database filed name
and the value will be
the list box name, in our
example the list box name is
"Dropdown1". Make sure
you check the box for "Use This
Search Form Filed" when you
specify criteria, in
the database results wizard.
