});

});

<input type="button" class="cli" name="clime" value="submit" onclick="clime()">

Answer 1

You seem to be missing the element with the id w3-btn which gets clicked programmatically.

Also, it seems both of these are doing the same thing ...

function clime(){
setInterval(function () {document.getElementById("#w3-btn").click();}, 3000);
alert();
}

and

$(document).ready(function () {
$(".cli").on('click', function(event){
    $("#w3-btn").trigger('click');
});

});

both are trying to click an element with id w3-btn, just in different ways. You only need one of them.
