I have a form in asp.net 3.5 , which has a master page and a child page (content page). The form has several questions, I am using the asp.net checkboxlist for a questions, since multiple options can be selected, if the user selects 'Other' on one of the selections, then they have to enter data into a textbox field.
I made the following client side javascript to validate this but, the code doesnt seem to check wheter the Other option value is selected, I believe it has to do with the way the html is rendered on the page,,,
Can you please suggest how to do this?
Thanks in advance.
Rendered Javascript
//Here I am trying to get the text property of the label rendered for the texbox
// and set my validation arguments
<script language='javascript' type='text/javascript'>
function checkOther2(oSrc, args) {
{
var elementRef =
document.getElementById('ctl00_Content_CheckBoxList1');
var checkBoxArray = elementRef.getElementsByTagName('input');
var checkedValues = '';
for (var i = 0; i < checkBoxArray.length; i++) {
var checkBoxRef = checkBoxArray[i];
if (checkBoxRef.checked == true) {
// You can only get the Text property, which
will be in an HTML label element.
var labelArray =
checkBoxRef.parentNode.getElementsByTagName('label');
if (labelArray.length > 0) {
if (checkedValues.length > 0)
checkedValues += ',';
checkedValues += labelArray[0].innerHTML.text;
if (checkedValues == 'Other') {
args.IsValid = !(args.Value == "")
// test
alert("Hello");
}
}
else {
args.IsValid = true;
}
}
}
}
}
// HTML Rendered

Your JS looks rather complicated. Try a more simple approach...
function isValid(f)
{
var cb = document.getElementById('<%=CheckBoxList1_3.ClientID%>');
if(cb && cb.checked)
{
var tb = document.ElementById('<%=txt2other.ClientID%>');
if(tb && tb.value.length > 0)
{
f.submit();
}
else
{
alert('Please enter a comment in question #2.');
}
}
}
If you have a lot of these, try setting a property on the checkbox like value=other
so when you loop through your checkboxes, you can use if(cb.checked && cb.value == 'other')
