Calling or triggering an external javascript twice

Adam Smith · Jul 26, 2006

Hello,

How can I call or trigger an external javascript twice in a form?
I have

<script language="JavaScript" src="country_state.js"
name="Country_State">
<script type="text/javascript" src="country_state.js">
</script>

set in between my HEAD tags.

In between the BODY tags I have
The first trigger

<td><select id="countrySelect" name="compcount"
onchange="populateState()"></select></td>
<td> <font size="-2"><b>State</b></font></td>
<td><select id="stateSelect" name="compstate"></select><script
type="text/javascript">initCountry('US'); </script></td>

Which works

the second trigger calling the same external script

<td><select id="countrySelect" name="contcount"
onchange="populateState()"></select></td>
<td><font size="-2"><b> State</b></font></td>
<td><select id="stateSelect" name="contstate"></select><script
type="text/javascript">initCountry('US'); </script></td>

Which does NOT work now?

The only difference is the name of the variables, "compcount",
"compstate", "contcount", "contstate", from the form input fields
I am not much of a java person, but can some one say why and suggest a
correction

Thanks

Adam

You should try validating that code. There is no name attribute for the

script tag. You are missing a closing said:

What does the function initCountry do?

Show the code for the external file. Or, post a URL to a sample page
that shows what you are trying to do.

Hi Randy,
Was trying to keep the post small by not posting the code. BTW, my
apology for the late response, I was dealing with a crescendo of
computer problems. The code is sort of lengthy and includes an
additional datafile. (I'll repost and shorten the original repl quote in
the interest of space, hope you'll be able to pick up the thread easily)

The sript is "A simple international country and state drop down list
that automatically repopulates the state section based on the country
selected without page refreshes. Select a country and the country's
states or provinces are listed ........ If the country doesn't have any
states or provines configured, an empty text box is displayed."

The script is from ==>
http://javascript.internet.com/forms/country-state-drop-down.html

It is being used in a form, in which the user may have two (2)
addresses, work and home, that may not necessarily be in the same Country.

I'm calling it twice but am having a problem with repeating the trigger
of the external *.js call of the country-state-drop-down script. The
trigger works perfectly fine on just the first call.
--------------------------------------------------------------------------------

In the *.html containing the Form I have set meta tags:
<meta http-equiv="content-type" content="Content-Script-Type"
CONTENT="text/javascript">

In the head setion there is (country_state.js is the external javascript
file)
<script type="text/javascript" src="country_state.js"></script>

In the Body section there are two sets of 'Table' entries:

1st entry ==>

<td width="12%" bgcolor="#7C9CCC"><font size="-2">City</font></td>
<td bgcolor="#dae0e0" width="12%"><input type="text" name="compcity"
size="15" maxlength="25"></td>
<td width="12%"><font size="-2">Country</font></td>
<td bgcolor="#dae0e0" colspan="2"><select id="countrySelect"
name="compcount" onchange="populateState()"></select></td>
<td bgcolor="#7C9CCC" width="12%"><font size="-2">State</font></td>
<td bgcolor="#dae0e0" colspan="2"><select id="stateSelect"
name="compstate"></select>
<script type="text/javascript">initCountry('US'); </script>
</td>

2nd entry ==>

<td width="12%" bgcolor="#7C9CCC"><font size="-2">City</font></td>
<td bgcolor="#DAE0E0" width="12%"><input type="text" name="contcity"
size="15" maxlength="25"></td>
<td width="12%"><font size="-2">Country</font></td>
<td bgcolor="#dae0e0" colspan="2"><select id="countrySelect"
name="contcount" onchange="populateState()"></select></td>
<td width="12%" bgcolor="#7C9CCC"><font size="-2">State</font></td>
<td colspan="2" bgcolor="#DAE0E0"><select id="stateSelect"
name="contstate"></select>
<script type="text/javascript">initCountry('US'); </script>
</td>
____________________________

Now, either drop down list works [singly, but not together] perfectly
well, [the 2nd only when the 1st is disabled], but not together.

How can I get them both to work in the same form?

I was assumming it to be validated since it apparently ran error free,
was there another method that you had in mind?

What does the function initCountry do?

The initCountry set a default value for the select option

Show the code for the external file. Or, post a URL to a sample page

Hi Randy,
Was trying to keep the post small by not posting the code.

The way to keep it small is to reduce it to post a small example that
illustrates the problem or provide a link. We didn't need hundreds of
lines of data files, probaly 5 or 10 would be plenty.

BTW, my
apology for the late response, I was dealing with a crescendo of
computer problems. The code is sort of lengthy and includes an
additional datafile. (I'll repost and shorten the original repl quote in
the interest of space, hope you'll be able to pick up the thread easily)

That doesn't save space, it wastes even more...

The sript is "A simple international country and state drop down list
that automatically repopulates the state section based on the country
selected without page refreshes. Select a country and the country's
states or provinces are listed ........ If the country doesn't have any
states or provines configured, an empty text box is displayed."

So you have a select element whose content is dependent on another
select - there are hundreds of those around, one is here:

<URL: http://www.javascripttoolbox.com/lib/dynamicoptionlist/ >

You will need to re-format the data files and make a few modifications.
Incidentally, setAttribute is broken on some popular browsers, so
avoid using it if possible and use 'dot' property accessors:

e.g. instead of:
inputEl.setAttribute("size", 20);

use:
inputEl.size = '20';

[...]

Java and JavaScript are slightly different, but anyway...

I noticed your first script tag in the head section is not closed.
Could that be part of the problem?

Can someone tell me if this a real tracker? Or is it one designed to show you a different message at certain times, ie. acting like one?	0	Jan 10, 2021
