Php AJAX不从MySQL更新列表

在创建一个带有FOR循环的文件并显示表中的所有记录之后，我将从表单数据插入数据库。我试图用页面上的数据刷新我的列表，而不是每次将新数据插入数据库时都刷新

main.php

<script type="text/javascript" >
    function fetch(){
        jQuery.ajax({
            url: '/ajax.php',
            success: function(data) {
                jQuery(data).hide().prependTo("#list").slideDown("slow");
                if(jQuery("#list li").length > 15){
                    jQuery('#list li:gt(14)').remove();
                }
                setTimeout("fetch()", 1000);
                console.log(data);
            }
        });
    }
</script>

函数fetch（）{
jQuery.ajax({
url:“/ajax.php”，
成功：功能（数据）{
jQuery（data）.hide（）.prependTo（“#list”）.slideDown（“slow”）；
if（jQuery（“#list li”）.length>15）{
jQuery（“#list li:gt（14）”）.remove（）；
}
setTimeout（“fetch（）”，1000）；
控制台日志（数据）；
}
});
}

你能告诉我们问题是什么吗？问题是列表没有更新，就像ajax请求不起作用一样，我修复了请求中的某些内容，它开始每秒请求我的ajax.php，但列表仍然没有用新数据刷新，我的问题是，到目前为止，我对ajax所做的一切都不起作用@jayblanchard您是否在浏览器控制台中查看ajax请求/响应以查看是否有任何错误。您是否在任何地方调用
fetch（）
？如果没有：为什么没有？如果是：控制台输出是什么？是的，当然我是在调用函数，当我调用它时，我只得到目标id，输出如下
