【中文标题】脚本在实际服务器中不起作用，但在 localhost XAMPP 中起作用

【英文标题】：Script not working in actual server but works in localhost XAMPP

【问题描述】：

我似乎找不到问题，因为我的代码在 localhost xampp 中工作。但是一旦我上传到实际的服务器它就不起作用了。

没有任何错误输出

当我提交表单时，它会输出加载程序，然后消失，<div id="status"></div> 没有输出成功消息或错误消息

javascript：

<script>
    function _(id) return document.getElementById(id); 
    function submitForm()
        _("bankbtn").disabled = true;
        _("status").innerhtml = '<div class="progress"><div class="progress-bar progress-bar-striped active" role="progressbar" aria-valuenow="100" aria-valuemin="0" aria-valuemax="100" style="width: 100%"><span class="sr-only">Loading...</span></div></div><br />';
        var formdata = new FormData();
        formdata.append( "bcountry", _("bcountry").value );
        formdata.append( "bname", _("bname").value );
        formdata.append( "baname", _("baname").value );
        formdata.append( "bno", _("bno").value );
        formdata.append( "bswift", _("bswift").value );
        var ajax = new XMLHttpRequest();
        ajax.open( "POST", "editbank_engine.php" );
        ajax.onreadystatechange = function() 
            if(ajax.readyState == 4 && ajax.status == 200) 
                if(ajax.responseText == "success")

                    _("editbank").innerHTML = '<div class="alert alert-success"><h2>Changes has been saved</h2></div>';
                 else 
                    _("status").innerHTML = ajax.responseText;
                    _("bankbtn").disabled = false;
                
            
        
        ajax.send( formdata );
    
</script>

?>

【问题讨论】：

错误报告可能在生产主机上被抑制。在 PHP 代码的开头插入 error_reporting(E_ALL); 以查看可能的错误消息。

【参考方案1】：

所以我发现了问题。它在我的 phpmyadmin （实际服务器） 我正在使用具有id of 0 的测试用户测试我的表单，我所要做的就是将其更改为 1，由于某种原因它不能设置为 0，否则它将无法工作
