Question

I am trying to set saveData when there is at least one field filled in:

    $(document).ready(function () {
        $(":input").each(function() {
            if($(this).val() != "") 
                window.setInterval(saveData, 5000);
        }
    });

There is a syntax error Expected ')' in this code.

What am I missing here?

Answer 1

each() is a function, so you need to close its invocation parentheses. You are missing the trailing one.

$(document).ready(function () {
    $(":input").each(function() {
        if($(this).val() != "") 
            window.setInterval(saveData, 5000);
    }); // <-- You were missing the closing `)` here.
});
