Question

I have the following script:

$(function() {
    $(".message").hide();

    function simulate_ajax_call()
    {
        $.ajax({
            url: "/echo/json/",
            success: function(){
                alert("done");
                $(".message").empty().html("done");
                $(".message").delay(1000).fadeOut(500);
            }
        });
    }

    $('.button').click(function() {
        $(".message").fadeIn(500);
        setTimeout("simulate_ajax_call()", 5000);
    });
});

With the following HTML:

<input type="button" value="button" class="button" />
<div class="message">loading...</div>

For some reason the setTimeout part is not working. i.e. it does not seem to call the function after 5000ms.

jsFiddle.

You need to replace:

setTimeout("simulate_ajax_call()", 5000);

with:

setTimeout(simulate_ajax_call, 5000);

You should avoid putting () at the end of the function name because otherwise it gets called/run immediately 🙂
