Javascript Functions in Apps

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,

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.

Hi Eric,

Have you time to consider my issue?

Thanks,

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...
