Unable to activate checkboxes with JavaScript

I have a programming task that involves creating and disabling checkboxes in an ASP.NET website. The checkbox creation code looks something like this:

cBox = New CheckBox
cBox.ID = "Link" & lngUSN & "|" & objTableMapping.DatasetName & "|" & CStr(objDRInput("URNs")) & "|" & intLinkCount & "|" & objTableMapping.Reference
cBox.InputAttributes.Add("class", "Link" & lngUSN & "|" & objTableMapping.DatasetName & "|" & CStr(objDRInput("URNs"))) '& "|" & intLinkCount)
cBox.Checked = False
cBox.Enabled = False

Once the page is loaded via AJAX, I need to enable these checkboxes using JavaScript:

window.onload = EnableLinkAndUnLinkCheckboxes;

function EnableLinkAndUnLinkCheckboxes()
    {
        //Go through all of the checkboxes on the webpage and ensure they are enabled
        var frm = document.forms[0];
        for (i = 0; i < frm.elements.length; i++) {
            if (frm.elements[i].type == "checkbox") {
                alert('got here')
                frm.elements[i].disabled = false;
                }
            }
    }

Despite reaching the code to enable the checkboxes ('Got here' alert appearing), they remain disabled. What could be causing this issue?

Answer №1

Give this method a shot.

function ActivateCheckboxLinks() {
        //Check all checkboxes on the page and make sure they are activated
        var form = document.forms[0];
        for (index = 0; index < form.elements.length; index++) {
            if (form.elements[index].type == "checkbox") {
                form.elements[index].removeAttribute('disabled');
                form.elements[index].parentElement.removeAttribute('disabled');
            }
        }
    }
