我正在尝试使用 PHP 和 ajax 将数据提交到 MySQL 数据库，但它没有提交数据，当我尝试使用默认页面重新加载方法提交数据时，它正在提交数据，可能是我的 ajax 代码中存在一些问题。请在这方面指导我。
HTML 代码:
<form method="POST" id="custForm" class="addcustform">

Ajax 代码:
$('.addcustform').submit(function(){
var data = $('#custForm').serialize();
$.ajax({
type : 'POST',
url : '../include/addcust.php',
data : data,
beforeSend: function()
{
//$("#alert").fadeOut();
$(".btn-addcust").html('Saving ...');
},
success : function(response)
{
if(response=="ok"){
setTimeout( function(){
// Do something after 1 second
$(".btn-addcust").html('Success');
} , 1000 );
}
//alert(data);
}
});
return false;
});
如有任何帮助，我们将不胜感激。谢谢
最佳答案
如果您使用 Chrome，则可以按F12，转到网络，然后提交表单并查看新添加的行，服务器的响应是什么样的(根据您发布的代码应该ok)。也许您将数据提交到了错误的 URL(尝试使用绝对 URL，如 /include/addcust.php)。
您尚未为按钮设置值，因此 jQuery 不会使其生效，并且 PHP 的第一行将导致 false。因此，只需将 value="submit" 添加到您的提交按钮即可。
关于javascript - 无法通过ajax提交数据，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/44156836/
