Javascript Functions in Apps

Hi Eric,

Thanks for the reply.

For the 'are you sure?' popup issue, I have code like this...
-----------------------------------------------------------------
const exportButton = document.getElementById('export');
    exportButton.addEventListener('click', function(e) {
    console.log('button was clicked');
    var proceed = confirm("Are you sure you want to download this file?");
    if (proceed) {
        downloadCSV();
    } else {
        //don't proceed
    }
});
-----------------------------------------------------------------
But this gives an error in the console when clicked...
    
       Ignored call to 'confirm()'. The document is sandboxed, and the 'allow-modals' keyword is not set.
-----------------------------------------------------------------

For the cookies I have this code...
-----------------------------------------------------------------
function setCookie(name,value,days) {
    var expires = "";
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days*24*60*60*1000));
        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + (value || "")  + expires + "; path=/";
}

function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') c = c.substring(1,c.length);
        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}
-----------------------------------------------------------------
If I do this:
-----------------------------------------------------------------
setCookie('test','hello',7)
testCookie = getCookie('test');
console.log(testCookie);
-----------------------------------------------------------------
Then it returns a null value. The document.cookie value looks like this...

Hi Eric,

Have you time to consider my issue?

Thanks,

Hi Eric,

Thanks for the advice. I have implemented localStorage and that works fine.

I can also create modals, but I'm not sure how the main code can interact with the modal e.g. how does the modal return a 'yes' or 'no' response, and how to put a button/listener on the modal. Can you point me in the right direction?

Thanks,

SGL.

I'm going to close this post as I am now able to save to localStorage, create modals and send messages between them.

I do have an additional issue with modals, but I will create a separate post for it.

Thanks,

SGL
