Update function to validate checkbox is checked
I have a function that is triggered by the click of a button. It validates that at least one checkbox is checked in the form. The problem is that the form has 2 checkboxes, one I do NOT need validated, but it is validating both apparently or validating the incorrect box.
This is my button
This is the checkbox I NEED validated that at least one is checked
This is the checkbox I DO NOT need validated (this may or not be checked)
This is my function. Which I think I need to update so that only validates the checkbox named 'box'
How can the function be modified to only validate that element?
This is my button
<button type="submit" class="btn btn-white" formaction="links_spunlinkusers.asp?caseid=<%=(rs_case.Fields.Item("Id").Value)%>" onclick="return oneCheckboxChecked(form1)"> Unlink </button>
This is the checkbox I NEED validated that at least one is checked
<input name="box" id = "box" type="checkbox" value="<%=(rs_users.Fields.Item("userid").Value)%>" >
This is the checkbox I DO NOT need validated (this may or not be checked)
<input class="i-checks" <%If (CStr((rs_users.Fields.Item("Xfer2Forms").Value)) = CStr("True")) Then Response.Write("checked") : Response.Write("")%> name="<%= (iCount & ".Qty") %>" type="checkbox" value="1">
This is my function. Which I think I need to update so that only validates the checkbox named 'box'
How can the function be modified to only validate that element?
<script language="JavaScript">
function oneCheckboxChecked(form){
for(f=0;f<form.length;f++){
if(form[f].type !="checkbox") continue;
if(form[f].checked){
return true;
}
}
alert("Select at least one User");{
return false;
}
}
</script>

In oneCheckBoxChecked, if the conditions are not met for form submission, return false which will prevent the default event. Also, remove the "return" from the button onclick call.

James, sorry I was updating the question, please read above. I need to have the function indicate which of the checkbox elements inside the form should be validated, I have two checkboxes but only need the one named 'box' validated and not the other one.

I added it like this and seems to work.
function oneCheckboxChecked(form){
for(f=0;f<form.length;f++){
if(form[f].type !="checkbox") continue;
if(form[f].getAttribute("name") == "box")
if(form[f].checked){
return true;
}
}
alert("Select at least one User");{
return false;
}
}
