[Javascript] Checkbox values
Hello.
I have a problem with this code ASP / Javascript.
The problem is JavaScript; try this LINK and select value cespiti
1) With ASP language is populated a secondary form, generated by a main form with a series of checkboxes, text fields and select;
2) Selecting different checkbox from a secondary form and compiled other fields, this values must be copied to a single field hidden in the principal form;
If the checkbox returned by the query SQL, is unique, the string:
is right and compiled values in the field hidden in principal form.
But if the checkbox returned by the query SQL are different, the string:
response with: - undefined;undefined;undefined;undefined
Can you help me?
kind regards
mike

Can you explain what you mean by "checkbox returned by the query SQL is unique/different"?

The problem is line 286: - <a href="javascript:insertf1(document.myform.SOTTODETTAGLIO _VERIFICA_6.value+';'+document.myform.Esito.value+ ';'+document.myform.ITEMS_6.value+';'+document.myf orm.ITEMS_KO_6.value)">
What do you actually want to happen? For example, if I select checkbox 1, do you want anything to appear, or do you always want to pass the last row data?

I need insert in the string: - <a href="javascript:insertf1(document.myform.SOTTODETTAGLIO _VERIFICA_6.value+';'+document.myform.Esito.value+ ';'+document.myform.ITEMS_6.value+';'+document.myf orm.ITEMS_KO_6.value)">
all the values selected in the secondary form and insert this string in the hidden field of the main form; whether a value or more values.

Is there a particular reason why the elements are named differently? You can use the same name, just not the same ID. If you have the same name, you can use document.getElementsByName() to get a list/array of elements which you can loop over. Check the checked property of the checkboxes to see if that row is one of the selected ones to pass the values through.

Ok, I try this but response with error 'Object required', why?: -
-
function insertf1(stringa)
-
-
{
-
-
var s = "";
-
for( var i = 0; i < 7; i++)
-
-
{
-
-
s += "," + document.getElementById('test_'+i).value;
-
-
}
-
window.opener.document.myform.dati_aggiuntivi.value=s;
-
-
return s.substr();
-
-
}
-
-
<select size="1" id=test_1" name="test_1">
-
...
-
</select>
-
-
<select size="1" id=test_2" name="test_2">
-
...
-
</select>
-
-
<select size="1" id=test_3" name="test_3">
-
...
-
</select>
-
-
<input type="checkbox" name="SOTTODETTAGLIO_VERIFICA_1" value="NCS43">
-
-
<input type="checkbox" name="SOTTODETTAGLIO_VERIFICA_2" value="NCS44">
-
-

You're starting from 0 and the IDs start from 1.

You're not passing anything to insertF1, so you can remove stringa.
In the above code, you have only 3 elements while the loop loops till 6.

Then the 7 should be replaced by a dynamic value generated from the server-side which changes depending on the number of fields.

Yes but this is already done: -
-
function insertf1(stringa)
-
-
{
-
-
var s = "";
-
for( var i = 1; i < 7; i++)
-
-
{
-
-
s += "," + document.getElementById('test_'+i).value;
-
-
}
-
window.opener.document.myform.dati_aggiuntivi.valu e = s;
-
-
return s.substr();
-
-
}
-
-
...
-
-
<form name="form">
-
-
<%
-
rs.MoveFirst()
-
Do While Not rs.EOF
-
%>
-
-
-
<input type="checkbox" name="DETTAGLIO" value="<%=rs("DETTAGLIO")%>">
-
-
<select size="1" id="test_<%=list%>" name="test_<%=list%>">
-
...
-
</select>
-
-
<select size="1" id="test_<%=list%>" name="test_<%=list%>">
-
...
-
</select>
-
-
<select size="1" id="test_<%=list%>" name="test_<%=list%>">
-
...
-
</select>
-
...
-
-
-
<%
-
rs.MoveNext()
-
Loop
-
%>
-
-
...
-
-
<a href="#" onclick="insertf1();return false;">

I meant on line 6, the 7 should be replaced by a dynamic value.
You have three select elements, but the code loops till 6, so it would be trying to access "test_4", "test_5", "test_6" which don't exist.

I don't think you've made any changes since the last time I checked. The code looks and behaves the same.
If you're using unique IDs, use document.getElementById(). If you're using names, use document.getElementsByName(). Alternatively, you could use document.getElementsByTagName("input") and then check the type/name.

Your help is not the help I think
However, thanks.

Something lost in translation?
I've seen the link, but the changes that you're showing in this thread are not reflected in the link. Also, the popup page is a .html file while you've shown that you're using ASP.

Oh, so you wanted all the fields in the form?
Anyway, glad to hear that you've managed to solve it.
