Question

I have a input text box. After the user is idle from typing I want it to submit the form(which works in the below code) and a image of a checkmark to popup then fadeout. I was just trying to test the fadeout function so the img is visible but I can’t seem to get it to work.

var timer = null;
$('.form_timer').keyup(function()
{
    if (timer) {
        clearTimeout(timer);
    }

    var test = $(this);
    timer = setTimeout(function() {
        test.next('img').fadeOut('slow');
        test.closest('form').submit();

    }, 700);
});

Updated my code to use parent then next. Seems .next works differently then I expected. I still don’t like this as a solution because the textfield could possibly be two levels deep in divs or etc…

var timer = null;
$('.form_timer').keyup(function()
{
    if (timer) {
        clearTimeout(timer);
    }

    var test = $(this);
    timer = setTimeout(function() {
        test.parent().next('.form_checkmark').fadeOut('slow');
        test.closest('form').submit();

    }, 700);
});

EDIT#1 Did some more digging
Doesn’t look like there is a easy solution for what I wanted. Found a solution someone else posted after I knew what i was looking for. Found here
