I'm trying to allow a user to select items from one listbox and add them to
a second list box, once the form is submitted the Javascript should set the
value of hdnThemes to all the items entered into the second list box
(lbxSelectedTheme), but of course that is not happening. Any ideas whats
wrong with the below code or do I need a new approach? Unfortunately since
taking over this project I have no way of reaching the orginal programmer
and my javascript skills need some major improvement!
<form id="frmImage" name="frmImage" method="post"
ENCTYPE="multipart/form-data" action="addimge.cfm?Upload=Yes"
onSubmit="return VerifyData();">
<input type="hidden" name="hdnThemes">
<select name="lbxTheme" size=5>
OptionA
OptionB
OptionC
OptionD
OptionE
/select>
<input type="button" name="btnThemeAdd" value="---->"
onClick="AddTheme();>
(The addTheme function is working fine, so I ommitted it to mimimize your
reading)
<select name="lbxSelectedTheme" size=5>
<option value='-'>------------------------------------</option>
</select>
<!----snippet from the VerifyData function that is called OnSubmit --->
// Get selected themes
for (i=1; i< document.frmImageAdm.lbxSelectedTheme.length; i++) {
if (vThemes == "") {
vThemes = document.frmImageAdm.lbxSelectedTheme.options[i].value
} else {
vThemes = vThemes + "," +
document.frmImageAdm.lbxSelectedTheme.options[i].value
}
}
document.frmImageAdm.hdnThemes.value = vThemes
Looks like it should be fine, but when I reference Form.hdnThemes it is
still NULL?
Thanks!
