Getting ERR_EMPTY_RESPONSE on $.POST

Question

I have a simple social networking site with chat functionality. I have used $.post a lot in multiple pages. The code works well on all pages except message.php

Answer 1

Instead of allowing your server to be spammed, you can remove the handler before the first post and set it back again when the post returns.

$(document).ready(function(e) {
    var $abc = $('.abc'); //good idea to cache those jQuery selectors!

    function abcPost() {
        $abc.off('keyup', abcPost)
        var a = $(this).val();
        $(".showoff").text("wait..");
        $.post('bbs.php', {
            a: a
        },
        function(abc) {
            $(".showoff").html(abc);
            $abc.on('keyup', abcPost)
        });
    }

    $abc.on('keyup', abcPost);

});
