hey guys trying to run this code:

<script>
document.addEventListener('DOMContentLoaded', function() {
const downloadLinks = document.querySelectorAll('[data-download="true"]');
downloadLinks.forEach(link => {
link.addEventListener('click', async function() {
try {
// Check if a member is logged in
const member = await window.memberstack.getCurrentMember();
if (!member.data) {
console.log('User is not logged in');
return;
} // Get the current member's JSON data
const jsonData = await window.memberstack.getMemberJSON();
const currentJson = jsonData.data || {}; // Initialize downloads array if it doesn't exist
const downloads = currentJson.downloads || []; // Add the current timestamp
downloads.push(new Date().toISOString());
currentJson.downloads = downloads; // Update the member's JSON data
await window.memberstack.updateMemberJSON({ json: currentJson });
console.log('Download timestamp added');
} catch (error) {
console.error('Error updating downloads:', error);
}
});
});
});
</script>

it triggers an event after clicking on a button, but i keep getting this error in the console:

"Error updating downloads: TypeError: Cannot read properties of undefined (reading 'getCurrentMember')
at HTMLAnchorElement. "

But im logged in as a member while testing

Hey @Marko Jurisic, can you try testing it with this code instead and see if it works?

<script>
document.addEventListener('DOMContentLoaded', function() {
    const downloadLinks = document.querySelectorAll('[data-download="true"]');
    const memberstack = window.$memberstackDom;
    downloadLinks.forEach(link => {
        link.addEventListener('click', async function() {
            try {
                // Check if a member is logged in
                const member = await memberstack.getCurrentMember();
                if (!member.data) {
                    console.log('User is not logged in');
                    return;
                }
                // Get the current member's JSON data
                const jsonData = await memberstack.getMemberJSON();
                const currentJson = jsonData.data || {};
                // Initialize downloads array if it doesn't exist
                const downloads = currentJson.downloads || [];
                // Add the current timestamp
                downloads.push(new Date().toISOString());
                currentJson.downloads = downloads;
                // Update the member's JSON data
                await memberstack.updateMemberJSON({ json: currentJson });
                console.log('Download timestamp added');
            } catch (error) {
                console.error('Error updating downloads:', error);
            }
        });
    });
});
</script>

"Download timestamp added"

It actually worked, what was the problem ?

THANK YOU MY MAN

You were using window.memberstack instead of window.$memberstackDom. AJ just declared a variable to reference to the correct library 😉
